How to wire your reverse camera with a switch

Wiring can get tricky sometimes. This is how I advise you to get around feedback on reverse lights when switching your backup cam on.

[@Jack-gu7rr]

Thanks for posting this video. It may be almost 6 years old but that doesn't make it any less helpful! After watching this video, I bought some 6 amp diodes from Lessco Electronics. I purchased a new head unit for my 2013 Silverado, and added a backup camera. I followed your instructions on your video and it works like a charm! Thank you!

[@pterodox123]

How long did the shipping take? If you can remember.

[@lakersfanalbq]

Dude , I don't care how old this video is - You are the MAN !!! Followed your tutorial to the T. Works like a champ first try. All you naysayers need to take a hike . Relay SMELAY . When you turn it on it does NOT have a jerky turn on. It is a smooth as butter transition . If you know ANYTHING about electronics , this is what you want . Thanks man I am HAPPY !!!

Used this yesterday to wire up reverse camera with override switch and worked perfectly. Cheers 👍

[@TheDro]

thank you, i was trying to figure this out last night and felt like my brain was frying so i decided to take a break until today and this is exactly the problem I was having! thanks thanks thanks! I knew there was something i needed to add in line just had no idea what to do.

[@virgiltorres4727]

Just an observation. You only need to diode isolate the reverse light wire. The other end of the overrride switch is at 12 volts so if you close the switch while the car is in reverse you get no current flow since the potential coming off the reverse wire and the switch is the same. Very well explained write up.

[@cristianlagow]

Thank you, I needed to join the three cables together for my install to work. Good I found your video.

[@tomcosta47]

I'm watching a video that is 6 years old but I think it's going to help me

[@DerpMcDerp101]

Probably one of the more informative videos I've seen actualy learned what a diode does and it's application very professional al stuff here thumbs up

[@toyotrustPR]

Thank you for the video Martin. Great info.

[@dennishasley5388]

Yes, this configuration looks like you would have it on when in reverse as well as when you wanted to. For me, having it work with the switch only is fine.

[@rollingthunder1751]

Great stuff, but I think only 1 diode on the reverse trigger wire might be good if we are just trying to keep the back up light from going on when the switch is closed. Also, a fuse coming from the power source to the switch might be a good thing.

[@s3uoq]

I thought this too but if you are using a switch with a light in it then that will illuminate when reverse is selected in gearbox. If you only want override switch to light up when using switch then double diode is necessary. This won't matter if it's a non illuminated switch though and a single diode can be used.

[@Jpcars636]

Can you do a diagram on how to wire it up on a switch without using reverse switch

[@rollingthunder1751]

@@Jpcars636 Just to clarify, are you saying you want the cam to work completely manually through a switch and not at all through the cars reveres light circuit?

[@rollingthunder1751]

@@s3uoq Right, I was speaking of a basic toggle. An illuminated switch or pilot light will light up from the reverse circuit. Not sure it would be as huge an issue as the back up light coming on but if it's not wanted then, yes, 2 diodes are needed.

[@Jpcars636]

@@rollingthunder1751 yes that’s better for me 👍

[@lettersquash]

Great vid, learned a lot, thanks. Waiting for my cam and LCD to arrive. Dumb question, is the red wire to the DVD Receiver's "camera input" the actual signal feed or just the power? Have you just ignored the video cable between cam and monitor? Less dumb question, maybe:- I'd like to power mine from an ignition-on 12V to use as a rearview mirror replacement in a van, but I'm not sure if there is a source in the rear light assembly. Should there be one in there somewhere? If not, do you reckon it's ok to power it from the tail light rather than backup light? I'll then put the side lights (running lights) on to use the rear view. I don't want to have to run a ign-on cable all the way from the front.

[@ToiletDuckify]

It's worth noting a lot of current stereos that can be used as a back up camera, have an input from the reverse lights, and an output to power up the camera. Stops this convoluted route with diodes, and simplifies the whole install.

[@jessestrum]

hi i learnt a lot from your videos please can you tell me what type of diodes to buy thanks for a great lesson cheers john

[@petertwiss4215]

Just wanted to ask: Does your diodes overheat? Seems that without a resistor in series, a large current draw will occur?

[@JuanPerez-yy5hr]

Thank you for the info

[@mattmadison4731]

Looks like he got lost trying to explain (kiss) keep it super simple don't waste time going to taillight if your going to toggle switch just go direct power like you were kinda showing at the end when it looked like you erased your reverse wire but at the end you wanted the wire can we have a part 2 video showing it the simple way with just a toggle switch and if needed the diode for the diode can you use the one that resembles a fuse or is the size to big as it would be easy to crimp a fuse holder and put the diode in there last note check the camera angle (seems like this is your early days keep it up and you'll have a good following )

[@DJMATIC2023]

Any chance you can do a tutorial on driving with backup camera not going off. I have a 2017 Chevy cruze and would like to figure out a way to wire a always going really cam so that as I'm driving I know what's coming up behind me or if there is anyone in the lanes I can't see.... Lol. Please your the best

[@scottyboy2400]

PLEASE REPLY ASAP! Great video! I just liked & subbed! ------------- BUT! Now I have a question for ya! If I am not wanting the camera on anytime I want it, just when in reverse, could I tap into the reverse light pos and rev light neg wires at the light which is right next to the camera of course, then run the vid cable and the reverse signal turn on wire (if that is what the other wire even is? SEE other question below) to the head unit? The reason I ask is before i found your video, i watched others that showed it done this way and i went ahead and run the wires as i wait for my head unit to arrive. Hoping I did not screw up and have to redo all i done because it was a pain in my 2011 prius to run the wires from the top of the hatch(where the tag is) down to the tail light then all the way to the front of the car! Also just to be sure, the video rca cable also has a little red-pigtail on each end of it. ----- I could not find out for sure about this pigtail so to be safe i went ahead and ran another wire from the rear pigtail to the front pigtail,(the red short wire found on each end of the video rca cable) just incase i am right and this wire will be used to let the HUnit know when to switch to cam by connecting it to the wire labeled reverse on the hu's wiring harness. Am I right or am I all screwed up??? Thanks! PLEASE HELP!

[@na-bm9wp]

2016 or 2015 silverado I would say find a constantly on 12v like off the battery put a diode on it and tie it in on 1739 (red) in the rear body junction box with a diode to prevent it from going back up to the ignition. Then find an always on neutral like off the battery and tie it in on 24 (white) in the rear body junction box with dual diodes to be safe (probably not needed since it is a neutral, but just to be safe anyway) and then break that neutral thru your switch and it should power the rear camera on and off thru your switch. Just my opinion, but looks like it would work. 4 diodes 2 wires and a switch should put it in business.

[@joshrandall9986]

So this may be a dumb question, but why are the diodes necessary? I am wanting to use a toggle switch for on off function so I can view at any point while towing and using a small separate lcd screen for viewing. I am using an add a circuit in the fuse box to tap for power. Thanks for answers and pointers.

[@antonioarcellana7243]

Sir, hi thank you for your video got better understanding now how to wire my camera using switch and diode. But one question on the 12V switch and 12V power coming from the tail light ... 1. How about if I forgot to turn off my switch and suddenly reverse my car, power supply from reverse light and my switch are both triggered? what will happen 2. My car still using halogen bulbs reverse light maybe about 21watts “guest only” what diode capacity is ideal? 3. hope you can help me to solve this question in my mind... thanks Anton

[@luffyfeecesroronoa2728]

so i got a 98 cav. bought a cheap radio cause i wasnt sure this would work anyway. on my video wire (yellow) each end has a red wire on each side which i assume is the 12 volt wire. i spliced this wire into the red wire on my pig tail of my radio which says its 12 volts. on the other end i dont know where to put it so i spiced into the red wire that draws power from the reverse light and i spliced the ground into the ground wire on my park lights. did i wire this wrong? needless to say it did not work.

[@JustisNme]

OK, great Vid, I went to your website but don't know what size diode I need, please help

[@Gondalenium]

I think this is more complicated than simply using a Single Pole Double Throw toggle switch. You also get the option of being able to turn it off all together. Thanks anyhow.

[@DerpMcDerp101]

Ok i wired up completley like you said now i tapped the reverse and the switch wires after diode and ran the red to the reverse signal wire on the stereo is that wrong ? because i am able to get the camera to show u with the switch on AV but the review doest come on when i revers back up camera app stays dark no matter what i do

How to modify this scheme if I want use with an uvc usb camera attached to a tablet? There is an app that can launch upon connecting the camera. So back llight relay/switch part of the scheme should work. It is not clear for me how to switch on camera bypassing the reverse.

[@bigdiesel891]

Wouldn't you only need one diode on the tail light? If the switch is off isn't that acting as a diode and if its left on when in reverse I don't think it would hurt anything, because you would be adding voltage to account for any drop from the extra wires. Not that diodes are expensive and I like the idea of isolating things for safety, I'm just wondering if there is a need for it.

[@achimgazelle3641]

Hello, I have installed an Android Radio with rear view camera and this is exactly the problem I am facing right now. I don't want to switch on the camera in reverse but also manually while driving. The problem is known. Then the reverse gear lamp will light up too. I wanted to do the same with the diodes but I didn't know how. Your video explains a lot more. I already have a switch for my USB charger in the front. I would like to steal the 12+ from this switch and send it to the camera. But what I don't understand is, why is it not enough to install a diode in front of the reverse lamp? do I have to install 2 diodes? Would there be a short circuit if I installed only 1 diode, because the 12+ goes from the reverse lamp to the switch? I happen to have an SR260 m10? diode. would that work too?

[@DerpMcDerp101]

its is hooked up like the diagram but the red wire is going to my violet and white striped revers signal wire im thinking that may be wrong no clue why it only works in av mode not in back up camera mode i was thinking maybe because of my relay that allows me to watch video while in motion idk

Instructions. Reverse taillight provides power to camera and must be connected to brown reverse wire of radio. Yellow rca camera to radio.black is Ground . I use ground of reverse light bulb.works fine. Put car reverse, radio switches to camera display

[@djnormil]

in this case without using the diode i would connect the camera straight to the battery power or to the remote power and connect reverse wire from the head unit to the reverse wire into the taillight reverse wire. you do not have to use any switch or diode

[@MrPaull1112]

Hi just watched this tutorial vid and it was great. I have a question. Instead of running an alternative 12v power supply to have a switch, Can also wiring the reverse camera to the Park lights and then turning the park lights on acts as the on/off switch for the camera? ( obviously the diodes will still be needed)

sure, no problem there.

Thats great dude, but not everybody has a dvd player. Why is it, no one can show a simple video on how to wire to your taillight?

[@yourface3154]

Also, with your last picture, seems with the placing of the tail light Diode, would prevent that tail light from working at all, correct?

[@yss2685]

No. It is just a tapped/jumped connection to (+) on tail light and it is not tail light's main power connection. Tail light is getting its power from a different source/switch that car has. Jumping to that connection is just providing you with a sense connection (when tail light is powered on).

[@acewilums]

Can't I just leave the reverse light circuit out of it all together and just wire it to power to turn on when the unit turns on ?

[@larrya703]

I don't understand why you need a diode for the switch. If for some reason the switch was accidentally closed while you were in reverse, would it even matter, it's all positive current anyway ?

Nice video ! Thanks for doing it! Here is my setup : Im running Front and Rear Cameras to Head unit utilizing both a toggle switch 2 Pole center off i.e. , ON/OFF/ON AND A SWITCH TO CONTROL Video feed and trigger the correct camera. The 2 Pole Toggle will control the front camera when I want it in the ON position constantly. I figure I need one diode at the Reverse Power on Tail light and one below the Head Unit where the diode makes contact with the trigger wires. The 2 Pole Toggle will have an adapt fuse before going to 12 Volts . The Head unit will also have an inline fuse to power . I have a schematic I could email if it would make life easier?Question : will 2 diodes be sufficient? Thanks Get Up and Go aka Papa

What would happen, if the switch is on (+12V) and I go into reverse (+12V)? Do I have an overvolt situation (+24V, series circuit) or is this (at 09:57) a parallel circuit and I would still have only +12V? I don't want to damange my stereo or camera.

that cannot physically happen, its electrically impossible.

[@PC-zq6er]

Hi, thank you for sharing your information, is there any possibility that the camera/monitor get damage from two incoming power sources? For example, 12volt 6amp diode from the battery plus 12 volt 6amp diode from the reverse light. Let say the switch is turned on while in reverse gear at the same time. Is it necessary to add two 6 amp fuses after each diode? Is it safe for two powers to be on at the same?

[@Junior-ji1om]

couldnt you do the same basic thing, only bypass the reverse connection at the tail light, and run 12 volts thru the switch to the radio reverse, and the camera power? you would have to manually switch the camera on when going into reverse, but it eliminates the need for diodes as well as eliminates the need to tap into the tail light wires.

[@Lesscoelectronics]

Sounds like alot of extra steps, but you can try it for yourself I suppose.

[@Skulskit]

im thinking about putting my back up cam on a switch, great video explaining it, but im more worried about the technical part, how would you wire in these diodes and protect them back behind the stereo? just solder and heat shrink?

[@Lesscoelectronics]

Tape is fine, but heat shrink is an even better option.

[@Skulskit]

Lessco Electronics ok thanks! and how come you only sell the 6A diodes in a 10 pack?

[@Lesscoelectronics]

I do 10 packs cause if I sold onsie, twosies Id lose $ after shipping little things like that.

[@Skulskit]

Lessco Electronics makes sense...one other question, do you have to bring the camera power wire back to the splice with the diodes? or can you just wire it to the reverse light in the back? and if you could do it this way do you still do the double diode isolation off the tail light and the switch?

[@Chemistmenace]

Skulskit Short answer: Yeah you have to bring it back. Long answer: If you wire it directly to the reverse light, your camera WILL get power. The problem is that if you don't bring the camera power wire back, your display WON'T get power and it WON'T recognize that the camera is on (it will think it's off). Therefore you will not see the camera's video on your display. Note: These backup cams are already designed in the simplest way possible, and there really aren't any shortcuts. If there was an easier way, they'd be doing it already.

[@samsen201]

Exactly what I wanted. However if I am going to add a second LCD screen (A 5 or 7 inch el chepo chines), dedicated to for the Second reverse camera! Wouldn't that be a good idea, for all time electronic rear view mirror, as my truck gives me very poor coverage through optical mirror (Lifted truck and what not). I ask this because of many reasons. First the current back up camera has Wide angel lens so really not suitable for permanent view and then has those not needed Stop / Waring lines for parking. Then By not messing with car's OEM system, I may cause less chance of damage to the HU, and camera that are going to be one 24/7, when car running. Additionally beside choosing a camera that has closer to normal human eye field of view, I am going to hang it on top of the back of the car or behind the rear glass, and not low, at bumper level, that again should give me a more realistic view of the back without making objects small/large or causing distortion of distance judgment. And who knows, may be in a future, a more sophisticated model, I may add two horizontally placed cameras to feed the same one screen, an turning the system into a passive LG type 3D picture that doesn't need a 3D glass to see 3D!!!! In this scenario, do I need to connect both the red wires of the LCD and 2nd dedicated back camera mirror, to an IGN red wire from under dash fuse box? Thanks man and you are a good teacher.

[@Lesscoelectronics]

Maybe something like this MC7101 video I did may be a more valid solution for you, Its all in one and the cameras are able to be viewed alone or split screen or or 3/4 or 4/4 on screen simultanously and can be switched manually or electronically with turn signals and reverse turn ons...

It would turn on anytime you used the switch. Effectively making it the same as a room with a light switch VS motion sensor. The switch adds a step but also versatility because you can turn it on when ever you want it.

i have a 94 astro and im trying to change out my rear view camera please help

[@Lesscoelectronics]

+Luis Santiago tell me how I can asssist

[@BAHRAMCR]

why not leave the backup camera on all the time while driving ?

[@GamerReels]

If connected to the radio it will be on the backup display. You could put two toggle switches one for the receiver one for the camera but if you direct connect the camera to say the battery it will be on all the time and run your battery dead.

[@brucebeverly2629]

Rob - Yes, the right way is to power the camera (+) lead from the ACC (Accessory) Red lead on the wiring harness behind the radio. The camera (-) lead connects to Audio GND (black) lead on the wiring harness behind the radio. The radio and camera will power ON and OFF together, as a properly designed system. Yes, these two power wires to the camera will be long, but they will be free of large ground currents elsewhere in your vehicle that will cause image distortion and possibly loss of sync with the radio video decoder. The Reverse lamp (+) lead connects ONLY to the radio's Reverse In input, which signals it to display your camera image when your vehicle is in reverse.

single pole double throw is simpler. no need for diodes. youre already going to put a switch in so just go with the spdt. you even said "diodes get hot" diodes get hot = more likely failure. the only benefit to this is if the switch fails you will still get the camera in reverse. if the spdt fails. you have no camera.

[@Lesscoelectronics]

diodes cant be replaced by a spst relay.

[@firebirdude2]

He said SPDT switch. Are you insinuating voltage could jump between the poles of the switch? Camera and monitor on the common, 12V ignition and reverse lights on the switching poles. Unless power jumps through the switch, you're isolated. Sorry, but you're thinking way too much into this.

[@nasilemak868]

To those who suggest running constant 12v to the camera, you cant do that to certain cameras with leds built in them.

[@mysterious_codm6812]

A question,I want my camara to turn on when i put it on reserve,but also sometimes just to check what I have on my hitch carrier,not always being on,just sometimes turning it on,will it be all good?

[@Jpcars636]

What type diode do ya need

[@Lesscoelectronics]

a standard 1 amp in1005 diode

[@Jpcars636]

@@Lesscoelectronics thanks mate

[@egastt]

What amp diode is recommended?

[@Lesscoelectronics]

I use 5 amp diodes usually

[@GordWall]

I like using a relay (SPDT) better than these diodes.

[@firebirdude2]

SPDT switch. No diodes. Done.

[@colewarner200]

Why two diodes? Is the one on the switch loop actually necessary? What is its purpose? Please don't tell me you only explained it this way in order to goad ppl into buying more diodes from your websites? Please explain. I'm no expert I'm just saying I don't understand its purpose.

[@p.max55hotmail25]

i did my from in side of my car never from the reverse lights there is a wire in side the cab that does the same things has the reverse lights do

Seems like an overly complicated way of doing things. This video suggests you need a switch and diodes (soldering, presumably) to arrange things, but I highly suspect that most head units (especially after-market) already have circuits in place to do this; just need to wire it correctly. He is right that the radio will be "looking" for a 12v trigger for the back-up camera. So you have a choice. If you want the camera to be on only when in reverse, then you can share the same circuit with the radio and the reverse (lights). If you want to be able to view the camera whenever the car is on, then the camera must be supplied by accessory power (running lights will often be able to this). The radio should not share the same 12v reverse circuit in this case. For the radio to automatically switch to the camera when in reverse though, it still needs to be wired in to the reverse circuit.

[@uawsux]

I installed dvn927bt with JBL adapter it whistles not all the time seems like it's only when it's quiet mostly because I probably can't hear it for the radio for DVD CD blah blah blah how do I get rid of that whistle I put a ground wire from the radio to the frame whistles still there it's just different wrench man 55 at yahoo.com

[@rixanneh18]

Rocket science it ain't. Run a red and black 12v to a toggle.

[@salceti]

should use a lapel mike and slow down your speaking too

[@AndresGarcia-yo5qt]

My humble opinion will be put a single pole swich to turn all , the camera , the reverse swicth of the receiver and dont hook it up to the reverse light. )the only thing it wiill turn on manualy with the switch.

[@seansinay8797]

If your switch is on when you go into reverse, you'll have an overvolt situation since both +12v sources will be in series with the head unit and the camera.. This is not the correct way to do this

[@maddog9659]

Sean Sinay 12VDC plus + 12VDC = 12VDC, you can't produce overvoltage at the load with a 12VDC Source, hook up 12 different wires from source to load and you'll still have 12VDC

[@rollingthunder1751]

+George S Correct, 12v positive is 12v positive.

[@MowSow]

This is absurd !! Just connect the reverse wire from the head unit to the reverse wire in the car harness, then connect the red wire (12V) to the red wire on the head unit that is already connected to the accessory wire in the car harness. This way the camera is on as soon as you turn the key. It will come on when you go into reverse, and also you can go into the head unit and switch to the rear camera input, and you can watch the rear when driving on the screen. Done

[@stephenlozada7158]

Noisy shoes

[@nelsonwilley062998d]

Every video is seriously pissing me off with this. If I never hook the power up to the reverse light how can you have a problem with it. All you had to say was dont plug it into the reverse light

[@andytaing8887]

JUST CUT THE REVERSE WIRE IN HAFT, PUT ONE DIODE BETWEEN AND YOU ARE DONE...

[@andytaing8887]

how about 4 cameras to stay on all time in cargo monitor, using just the same rear camera as a backup camera with a switch to the head unit?

[@MrNatesluvs]

He is a salesman, a bad one. Even had to read off the paper a double pole single throw lol. So why not a relay?

[@MrNatesluvs]

Oh come on. How long you been doing this? First off from the camera just hook up the red wire to the positive wire on the light that turns on when you put your car in reverse. Second run a wire from you units back up power, usually light purple with a stripe to the same hot wire. Camera can be turned on from the head unit will also automatically switch on when gear in placed in reverse. No need for switches or diodes. How silly.

[@davecarlson9350]

Your reverse lights will be on any time your camera is on if you wire it the way you suggest.

[@MrNatesluvs]

Nope they are not.

[@massesbulet]

So the power source for the camera it gonna be the source for the wire that says reverse on head unit so they can kick together when I put on reverse automatically please help thanks
