Car Camera Wiring Tip - Using the red tail wire for power

🔔 Please CLICK THE BELL if you want to see my videos! 🔔
If you've ever looked at one of those Amazon or eBay car cameras and wondered how you wire it, maybe this will help. Yes... that red lead coming out of the video cable can be used to run power to the camera... and I had a surprising accidental discovery about the ground!

That red wire on the video cable is for instant on in reverse. It is connected with the power wire to camera which is connected to reverse light and the one at the radio side connects to your radios wiring harness labeled reverse gear signal input. So now when you put in reverse it automatically switches to camera mode and when you put it in drive it then will go to the last mode you where on.

[@nickkennedy4218]

This was what I also thought as well. I didn’t think it was for actually powering the camera, but only to wire with the head units reverse trigger wire.

[@adamjensen6376]

I know this post is couple months old but I got a question here I just bought a new stereo android and its got brake, reverse and key 2. can you tell me what is key 2 and brake for where do I wire them up at Thanks

[@guccimane5752]

Aaron Darren if your car doesn’t have those wires, I believe you just leave them alone

[@adamjensen6376]

@@guccimane5752 I found out what they are and your correct those wires are for vehicles who don't have keys on their steering wheel Thanks bro

[@ultrakewlkidd]

So do you hook the black and red both to the reverse light?

[@batfenderman7212]

As far as the ground wire that is part of the 12v feed at the camera end, you may not want to connect it to ground. This is because there is already a ground connection at the head unit (monitor). If you connect grounds at both ends you can end up with a ground loop. If you have screen flicker with backup camera activated, try removing the ground connection at camera end and you may find that flicker disappears.

[@MonaichFother]

I've installed a dozen of these cameras and there's nothing new this video can show me- Wait What?? :O

[@juanguerrero1747]

Thanks man everyone else on KZbin makes this set up look messy 🙎🏽‍♂️ but this videos great !!

[@tbonemalone6678]

The red wire that runs in the harness with the yellow video signal wire is meant to be used for the signal from the camera back to the head unit so the head unit knows when to switch the screen to camera mode. This video makes no mention of this important function. Also, the only time you wouldn't need to connect the camera ground wire is if the camera mounting hardware was acting as a ground through contact with the vehicle chasis.

[@submittedbymail]

I have an android head unit. Can I set the rear camera to record all the time, but still take the screen when put in reverse?

[@marcellochriscitiello1870]

The android radio turns the video mode automatically on as soon as you put reverse. Even if the camera is not installed at all!

[@extrakimF]

No it doesn't.

[@extrakimF]

@@batfenderman7212 if that's the case you should run the ground wire from the camera to the same spot that you grounded the head unit. You shouldn't use the RCA as ground.

[@thenathans96]

Awesome, thanks for the explanation of that mysterious red wire!

[@BradPaul1863]

Very good. You got the basics covered clearly in less than 5 minutes compared to the "other" guys that took twice as long to make things somewhat confusing. Thank you.

[@xavifut]

Especially when they tell you their life story before describing what u were actually looking for in the first place

[@cameronowens8921]

Thanks for the informative video! I'm getting ready to install one on my TJ & the ATOTO SA102 headunit has the red 12V lead available. However if I want the camera to only come on during reversing would I use the other 12V lead close to the camera & tap into the reverse light power?

[@MrJfred78]

Thank you! The instructions that came with my camera said to hook up both red wires to power and I thought that didn't make since and it should be one or the other. Glad I found your video.

[@chefro1]

I too wired an aftermarket camera (nearly identical to yours) to a 2-DIN aftermarket head unit in a VW Jetta Sportwagen - these cars have CANBUS. As any other "standard" instructions, I have tapped into the Reverse Light connector. What happened was that I would turn the key to Accessories (only), shift into Reverse and have video feed. However, with the engine operational when shifting into Reverse I would only get a blank screen with only the grid lines-feature incorporated into that head unit. I combed through a lot of videos on youtube and various information in forums and finally I have seen someone's comment who said that if the CAR HAS CANBUS - do not tap into Reverse Light. If the new head unit preserves the functionality of the Canbus then it should power up automatically the camera when shifted in reverse. That's another tip. What I wanted to comment about is your "Ground" note toward the end. Actually I disconnected that separate or "local" ground wire when troubleshooting my situation and the camera had no feed. I too was thinking that the ground is already carried out through the RCA wire to and through the head unit which is already grounded. That was wrong. As soon as I reconnected that local ground I had video feed. I'm not sure what your further research has unveiled, but you might consider amending your video (which provides an excellent how-to, btw) with complete information concerning that local ground wire. Thanks. good luck

[@TheChapen]

Hello Ionel P. Just came across your comment while looking for the solution for my reverse camera. When I put the car in reverse, I only get that "blank screen with the grid line-features" as you mentioned. What did you say was the solution the get the camera to work normally? Thanks in advance

[@fredben56]

Peugeot 107 needs ground to otherwise there is no video feed.

[@Phil-Sands]

This way of installing the power wire at the radio end only works if the radio switches to reverse camera mode using CANBUS, if it's a cheep Chinese radio the camera end needs the red connected to the reverse bulb 12v feed and black to ground or leave disconnected and use the phono plug ground, the red wire at the radio end will need to be connected to the radio reverse signal terminal.

[@ChiacchieraconMichele]

Thank you! This makes it a lot more clear. I've been searching on the internet everywhere and have been very unsuccessful in finding an answer. Thanks again!

[@rockymountainplecos1058]

This video clears it up for me. Was so confused about the two red wire sticking off the yellow rca plug.

[@IvanMarino]

Hello, im using a NDDN-W56 toyota navigator and need assist to mount the carvox led 333 reverse cam and i cant see where to connect the reverse trigger red cable. Can you assist? Thank you

[@francisco5434]

My head unit (cheap but good, Boss) has backup camera and alternately rear video feed selection from the touch screen, so I chose to draw power from my rear license lamp. I can now turn the camera on/off with my driving light switch. I don't have to be in reverse to power the camera on. That way, I can see traffic behind me while driving: tailgater's license numbers or just watch behind me while parked. I also hard-wired my mirror dash cam from my dome/courtesy lights (ignition hot,) so it starts recording as soon as I start the car and there is no wire dangling down to my cigarette lighter. I did have to buy a separate 5V USB step-down transformer, but it looks stock, with only a 2" lead going under the headliner. My mirror cam has an extra video feed to record both from the front-facing and a second camera. I could split the feed from my backup camera and run the video signal to the dash cam to record both views. But, I chose instead to install a second cheap camera pointing out the back window, powered the same way, for higher resolution. This would work with any brand camera, head unit combination.

[@nacelnik]

Hello, I do have FPV camera and monitor but is there why that my rear light will be able to run this camera, or will it "burn" it. btw. I run this "system" with battery but now I want to get rid of them. What do you think? Quanum ELITE QB58 Transmitter power: 25mW Input power: 2.5~5V Thank you very much.

Finally got an answer from you after watching 10 other videos. Simple and clear! Thank you for the vid!

[@CesarQuinteros]

Thank you! I looked through a bunch of videos for what the red cables meant! Even considered not putting in the backup camera because I wasn't sure about the red wire. Thanks!

[@RVingTheCountry]

Great. Thanks So question... will my radio, I just got the Heigh10... will that notify my camera to turn on or do I still have to tap into my reverse wire on the taillight?

[@jacobk9049]

When you do this, do you typically wire the power wire for the back up camera to the power wire for the radio or do you run it to the battery?

[@jerichobrady4179]

On a 2012 ram would u advise splicing the 12v wire and the reverse wire onto the 7 pin trailer plug wires or running both straight to the dash

Wat color is the wire

[@nickglowacki7010]

Very informative, it's exactly what I was looking for. Thank You!

[@PattonDickson]

So about to install one of these in my TJ, i was planning on running the red wire off my backup lamp or hitch reverse wiring. If I am understanding correctly, I can ignore the red wire with the video feed if I am getting power from the back of the Jeep.

[@AllscanTwelve]

can you cut the yellow RCA cable (though it's long but what if it is short) that goes to the head unit to connect a new wire, say 16 gauge wire, in between to extend it?

[@Nickoli0811]

Can I install the red wire into the red 12v on the back of the head unit instead of the purple video viewer. And then run a wire from the kick panel and find the reverse light wire and run that to the purple video viewer cable? That way I can view the camera whenever I want as well as have it kick on when put into reverse? Thanks

[@rafaelaguadalupe3167]

Hello My name is ralphie, I too was searching for the rear view reversing camera. While looking through the images and reading the descriptions. It explains how one can connect the red and black wire meaning the negative and positive to any reverse brake light. I was confused for a little while, but I didn't realize there are so many different reversing cameras for different vehicles. And what I also realized is that most of these products don't include extendable wires to make the connection easy and comfortable to install. Great video.i definitely understand how it works thanks.

[@SDSproductionsLLC]

Just tried this! It works. No need to ground the black wire to ground. Power can come from the radio connection. Connect the red cables together at the camera end. Thanks!

[@joziksk4323]

Hello Can i connect camera and monitor wires to parking light ? 2 cables on + and 2 cables on black

[@JerryJ26]

An added tip that I use is to not use the ground wire spliced to the backup light ground wire. I drill a pilot hole near in the body near the camera, then rotary brush the area around the hole to get bare metal. Crimp a eye terminal to the ground wire and attach it to the chassis hole with a self tapping screw to ensure a good bond.

[@zjhildreth]

That seems like that’s a better idea than letting it ground thru the head units video ground. I’m no expert, but it seems like that tidbit of information he shared in this vid wouldn’t meet an actual electrician’s approval. Your way seems like it a better bet

[@MannyGonzalezReyna]

You have the exact right way.

[@eddward758]

Bro, quick question .. if i use the constant power thats going to the head unit to connect the “ pig tail “ for the camera to power up.. how does it come on when i put the car in reverse?

[@KhanHS]

Perfect. Just what I needed to know. Been to 4 different Auto electricians to connect a power and ground for me and they all fobbed me off to come another day as it's a lengthy job and 1 even went on to say he needs the trigger wire to run to the reverse lights too lmao. Watched your video. Camera was already in place as well as wiring. Just connected the trigger to the red on camera and it fired up in reverse. My xtrons unit actually had a wire labelled reverse behind the headunit so other trigger wire went to that. Literally took me 5 mins to get my reverse camera working. Thanks again

[@chrisb8870]

Can you explain this again please? My radio instructions say to connect Headunit's brown (Back/Reverse) wire on its harness to Car reverse trigger wire. I already fed the Camera at Rear Reverse light harness in trunk. I found the Bulb/harness and tapped the (+) to Red of Cam and (-) Black to Ground in trunk also. The NightVision LEDs go on when I put gearshift into Reverse but Camera does Not show up on Radio. What do I connect Brown wire to from Headunit?

[@KhanHS]

@@chrisb8870 Sounds like you do have power as the leds turn on. Are you sure you connected the camera video feed to the correct input on headunit side? Try other inputs too incase they been labelled wrong on headunit.

[@chrisb8870]

Did you connect the small red wire on Camera wire/Near Radio to anything? I didn't connect it because I already connected other end of Red wire/Camera Side to reverse lights wiring in trunk. Do you still comnect the other red to the radios wire(Marked Reverse)

[@KhanHS]

@@chrisb8870 Yh so my radio (xtrons) had a wire on headunit side for it to connect to. I used the trigger wire only and didnt connect to reverse light at all but my headunit also has canbus so it only needed the trigger wire to get it working when putting in reverse

[@GrizzleGear]

So did you get your power from the red 12v wire or did you use the yellow acc?

[@aq8973]

great video! easy to understand. did you ever find out about that black ground wire? thanks

[@papabilhas]

Easy way; Plug the yellow rca to the radio and the red(power) on to red wire coming out from the radio( normaly its a red wire identification with ccd power), that means you have power. Then you have to connect the other yellow rca to the camera(witch is the signal that comes from the rear camera to the radio). Finally connect both wires from the interface(red and black) to the reverse light. Using red with red and black with black. Don t forget to connect the red wire from the rca cable with other 2 red wires coming from the reverse light also as you ve done with the black ones. Done!

[@RikAindow]

My car, a 2007 Ford Mondeo, has a weird switched polarity tail light. What you think is ground is actually live, and turning on a signal, putting the car in reverse etc, actually switches on the ground for that light. I believe it's done this way so that if the car's control module fails, the lights turn on for safety. So to get around that headache (and CANBUS), here's how I wired the camera. The black lead from the camera went to a ground point near the camera. I used a tail light screw. The red power cable connected to the red cable on one end of the video cable. I ran the video cable to the head unit and connected it to the camera socket on my headunit. The red power cable was then connected to my headunits remote turn on lead (usually used for amps etc). By doing this, I was able to get a camera that is permanently live when the stereo is on so can be used at any time. My headunit wiring harness adapter had a reversing light signal output which I connected to the headunit reversing sensor. Hey presto! The camera automatically shows when I enter reverse, or manually switch to the camera input.

they share the same ground or neutral line if they are directly connected to same power source (car battery). But there are dashcam monitors that are battery backed up to avoid relying on ACC of car.

Funny u mentioned this because the same exact scenario happened to me. As I was wiring cam up I noticed everything was working and I hadn't even wired up the ground yet so I left it be. Everything ran fine without issue for a month & then screen started flickering intermittently. I went through everything & couldn't figure out the prob. Ended up finally terminating the ground & wala...back in business. Still can't make heads or tails out of it. Glad to hear that everything's running smooth on Seicane, looks like they addressed some passed issues with revised edition.

I'm confused why you made no mention of which wire from the harness you connected that to, yes 12vdc source but in some cases there is a few sources right at the stereo. My problem is I've already crimped my accessory red and my constant yellow and I'm looking at this blue wire that says remote output 12 volts 500 mAh, and I'm wondering if I can run it off of that rather than cut one of the lines I've already crimped.

[@viewer2325]

thank you. Your first 3 minutes I think answers my questions, I will find out tomorrow.

[@BruiSSer81]

A lot of people have asked but I haven’t seen an answer, does this method mean the camera can be viewed while not in reverse also since it’s connected to the head unit power source not the reverse light wire??

[@m.sm.1159]

But the head unit has a wire in the harness that is in my case is pink. It's says the short red wire next to the rca connects to that. Do you just connect the pink wire, the red wire and run them to my reverse light triggered 12v in my dash?

So one red to the head unite and the other red just nothing right

[@superspicytofu]

1 red to head unit, the other end plus the power in red are tied together and connected to the reversing light. When put into reverse, camera turns on, signal is sent to headunit to reverse.

[@JimboX1461]

You didn't mention the reverse trigger wire which is going to confuse people. Most people use the red wire on the RCA cable for the reverse light to trigger the camera. The way you set it up you will have access to the camera at all times but unless you run a separate wire for the reverse trigger it won't automatically come on when in reverse.

[@gregoryminogue1350]

I have done exactly as you suggest - the camera works when I go into reverse. The issue is the LEDs around the camera are on 100% of the time when the car is on. I spliced the RED power wire at the head unit into the wire going to 12v Ignition?

[@MrFear41]

I hooked this camera up to my 5200 pioneer stereo head unit. I just plug yellow video and left red along on the head unit of stereo. And wired it to my rear tail light. It works but I have to go into settings on my stereo to turn camera on every time. Have any idea why

[@aliferoz007]

Brent you got to put video light with little red wire hanging... Thats usefull thing

[@olddirtyburt7522]

The red wire that is with the yelllow RCA is your trigger to turn the camera on and off when it sees 12volts. Those 12 volts are supplied from the rear of the vehicle, courtesy of your recerse lights going on when you back up. When the back up lights are on, they privide power to the camera and power to the head units trigger ( marked reverse lights or camera) and allow the head unit to immediately go into camera mode. When the reverse lights are off, camera is off.

[@d.j.9961]

Real quickly, I glanced at a pontiac g5 & the reverse lights are down beside the license plate, not within the tail light.at 1st glance, I do not see a good way of routing the camera wiring threw the trunk & out to the reverse light. I need to track the wires but, I also need opening to route the cam. Another issue I am having is the dimming if the head unit with the headlights. It does not have switched power on the red wire so, I ran a fuse tap to a switched source directly to the fusebox

[@VICKSTEEL]

Awsome got right to the info I needed thank you

[@miguelc9358]

If anyone sees videos for 2013 BMW F10 models installing power to fuse box in the trunk for after market backup camera, please provide as I haven't found any yet. Thanks.

[@jru2284]

Does this make it so you can turn the camera on when you are not in reverse?

[@jennyomalley7634]

Also I thought the red pig-tail was to connect to the reverse on the head screen and the other end to the reversing light as a sort of switch wire so when you put the car into reverse it switch's on the camera.

EXCELLENT VIDEO WITH GREAT INFO ON RED PIG TAIL

[@supersaiyanyaaj4219]

Thanks for the tutorial and great explanation but when I did the same connection as in this video clip, key in ACC mode engine not start gear in reverse my camera will only display/come on. When I startup car and put in reverse the camera lost signal. I then separate the little red wire to reverse backup light only and run the power cable separate to a 12v fuse box. Everything work when I startup the car gear in reverse, so I really don't know why it doesn't when I combine (red cable, power cabe to the reverse light like in this video.) It could be the my car is different not so sure my car is a Q5.

Does Connecting the short red pig-tale the way you said to the power plug solve the interference problem? And after putting them together i’m I suppose to connect them also to the backlight ?
