Car Stereo Wiring Explained In Detail

I go over a standard 16 pin harness and tell you all the functions in it. applies to: Car Stereo and Marine stereo systems, Wiring Explained In Detail.
Usually, it is best to make all of the new stereo's wiring connections via the wiring harness, but if you have to make a direct power connection, you'll need to know the difference between "switched" and "constant" power:
A switched power source is only on when the ignition is keyed. Connect your new stereo's main (switched) power lead - usually a red wire - to a switched power source, so that the stereo will turn off when you turn off the car, and not drain your vehicle's battery.
A constant power source is always on. Connect your new stereo's memory lead - usually a yellow wire - to a constant power source, so that you don't lose your radio station presets, tone control presets, and clock settings every time you turn off the vehicle.
Although rare, a few high-powered stereos require you to make a direct constant power connection at the positive terminal of your vehicle's battery. This requires a heavier gauge power wire, an in-line fuse (usually included), and a ring terminal to connect the power wire to the battery clamp. You will have to route the power wire to the battery location, which is often through the vehicle firewall and into the engine compartment in order to make the connection at the battery.
Speaker wires
Car stereos have eight wires for the traditional 4-speaker system - a positive wire and a negative wire for the front left, front right, rear left, and rear right speakers. Depending on the wiring configuration in your vehicle and the wiring harness adapter we offer, some of these may not be used.
Ground wire
A good ground connection is vital for proper stereo performance and to eliminate unwanted noise. If you are not using a custom wiring harness, look for a bare, unpainted bolt or screw that contacts the bare metal of your vehicle's chassis. Loosen the bolt, slip the ground wire underneath (this is almost always a black wire), then tighten the bolt. If your ground wire doesn't contact bare metal, your stereo won't operate. A loose or weak ground connection can result in signal noise interfering with your music.
In-dash video - tapping into the parking brake wire
If your new stereo has a touchscreen or video monitor, you will also need to connect a wire to your emergency/parking brake wire. This wire acts as a switch to turn on the video monitor when the parking brake is engaged.
This wire can be in different locations in different vehicles, depending on the brake configuration. The wire is usually found where your parking brake is. In vehicles that have a hand brake between the front seats, you'll have to remove the center console to get to it. In vehicles that have a foot-pedal parking brake, the stereo's wire will need to be routed to it under that dash. Either way, it isn't too hard, just take your time. And once again, award-winning tech support team can be a big help in locating it and helping you get to it.

[@josephdickson3531]

Thank you this helped immensely! I had a 1988 Kenwood (KRC-757) and it had slightly different wires such as one blue I don't know what it does, but I managed to get it running by putting positive on red plus yellow and negative on black. Thank you! :D

[@JoshuaCosimi]

Hey by chance did your early kenwood have plugin speaker wires similar to the krc 999?

[@MNDashcam]

Very helpful, thank you! I wire a lot of audio already but the wiring in my 96 Mustang GT is a nightmare because of the previous owner.. This will help me a lot with putting in a different aftermarket stereo than what is in there now.

[@jameslunsford2599]

Thanks for the tutorial. now I'm off to tackle my wife's Grand am and 20 degree temps. See ya on the busted-Knuckle side!

[@tomshiba51]

I found your video first, and at less than eight minutes, it looks like the shortest video I've found on this subject so far. Thank you for being concise and on point. The bundle of wires on my most recent HU purchase doesn't look so intimidating now.

[@gavbam]

Just watched your tutorial and would like to say Thank you for educating me on how to re-wire a radio. Having just recently bought a campervan I want to know what each wire is however accidently 'yanking' the molex connecter several wires came out, this is now going to be easier to diagnose. Cheers (UK)

[@jayzah]

Thanks so much for this! got a bit confused at one point installing a stereo into my car. Turns Out my toyota has diffrent coloured constant, earth and key power wires lol but thanks to your information and a wiring diagram of my car i found online i was able to successfully install my stereo :)

[@Dillion2221992]

this video helped me install the stereo in my jeep. I had no clue where to start before watching this video. Many of the videos out there will show you how to install with a vehicle specific adapter (which I didn't really want to go buy) but this video helped me understand how it all works and which wires are for what. This allowed me to do all the wiring myself in less than an hour without going and buying an adapter. Thank you Lessco Electronics.

[@Lesscoelectronics]

Dylan Adams youre welcome

[@jackiieboiiwang9463]

For me I used.. Power = blue w/yellow stripe wire from the deck(dash) and connected it to the red wire and yellow wire twisted together from the stereo(after market stereo) EARTH = black to black. For the BACK SPEAKERS = red from the deck(dash) connected to Pink from stereo(aftermarket 1). White from deck(dash) connected to pink w/black stripe from stereo. Yellow from deck(dash) connected to green w/black stripe from stereo. And grey from deck(dash) connected to green from stereo. FRONT SPEAKERS = green from deck(dash) to grey from stereo. Purple from deck(dash) to white w/black stripe from stereo. Pink from deck(dash) to white. And blue from deck(dash) to grey w/black stripe. Now this worked for me but you know how they say it CAN DEPEND on your model, make or car/stereos as some are DIFFERENT! Remember unplug your car battery before connecting all wires. Other then that hope this helps someone.

[@juancanada2018]

For my adapter that came with the aftermarket deck came with a blue striped cable but not with the solid blue one and my adapter that goes to the factory harness has a solid blue cable but not a striped blue cable for my 2000 honda accord.. Isnt my blue cable for am/fm? What should i do ?? Please

[@spectreduloft]

Blue to power antenna - factory harness Blues/White to amplifier - factory harness usually each code color are the same for any brand of radio. I plug the blue to the Blues/White i installed my JVC radio today and it work perfect.

[@danielslc88]

Juan Canada still don't get it.

[@AdrianWitzil]

Thank you for the info. I appreciate the help. Im a complete amateur but your video has been extremely helpful.

[@matthewzamora5503]

Thanks for explaining the harness connection includes not only power, but also audio. Makes a shit ton more sense, since Pioneer AVH series stereos do not explicitly provide this explanation.

[@coffeebotography]

Differentiate between BAT and ACC power.

[@nascar9059]

Switch the red to yellow and yellow to red

[@Taz981]

@@nascar9059 I want my radio to play even when car is off - so that I turn the radio off manually.. If I understand correctly I can achieve this by switching red and yellow wire? Right now my radio shuts down the moment I turn off my car...

[@Taz981]

To achieve what I wanted is quite simple - peel (not cut) both red and yellow wire and join them together. Insulate. :)

[@118118118rory]

Hello, i want to wire my stereo to my leisure battery, i was going to do it by running a permanant memory feed into the memory slot and then running another permanant feed with a switch into the ignition switch slot. Will this work? will be running from a 12v fuse box so no need for inline fuses etc.

[@catcall569]

Thank you for this video. Your explanation of the wires and colors were excellent. Not every guy has had experience installing car radios. It would be awesome if you could explain the wiring and colors for cars with steering wheel controls.

[@sccndc]

If you don't care about the receiver remembering, can you combine yellow and red to a single positive 12v source? I ask because that's all I have from my old boat radio. This set up powers the receiver but I can't get sound to the speakers. the receiver and speakers are brand new kenwoods. not enough amps from the old power source? thanks in advance, you really know your stuff!

[@artv4nd3l4y]

Steven Collova Provided that the 12v source can provide enough amperage, this will work and will obviously erase data each time it's turned off. If you're tapping to a fuse such as the cigarette lighter, be sure it can provide enough amperage for both the head unit and the cigarette lighter. Otherwise if you draw too much power consistently for long enough it will blow the fuse regularly. This is the only issue I would see if you don't care about presets being saved, good luck hope this helps.

[@sccndc]

ashokk sethi Thank you! I tried a bench test suggested by Kenwood and I think it's a faulty unit.

[@artv4nd3l4y]

Hmm, bcae1 website is a great source for troubleshooting, I have learned a great deal from him. Google bcae1. good luck hope you're able to get it fixed and don't have to buy a new one like I did when mine said miswiring for no reason.

Harness so when I cut it from plug and tied it together my lights came on with out it running or manually turned on.. so I'm trying to trouble shoot that and also when I plugged radio in it didn't come on minus the orange wire so I would like to know if it being unhooked could affect it also thanks.

how do you fix the wiring if the preexisting factory harness was cut out completely but you have the 16 pin harness for the deck, how would i wire in all those wires to the factory ones without the clip-in harness which is then supposed to be wired into the 16 pin harness that comes with the stereo?

Hello quick question about my car audio install. I’m using an Xelon Audio headunit with the stock door speakers.

i am using a sony radio from my integra, (aftermarket) and i want to install it in a new hynudai i bought last week. the wiring is all different. there are 3 brown wires, 3 grey wires, 1 white 2 purples and i looked up hyudai sonata harness diagram and is still not working. on the diagram i noticed something saying A+ B+ LUM and ground. i am assuming the black is the ground wire, but when i pulled out the radio there was a separate ground wire from the power source to the frame of the car. any help would be appreciated.

[@Lesscoelectronics]

+MykeLyppaTV that needs to connect your factory amp turn on wire, you probably put the blue there instead of the blu/wht I'm thinking..

Blue and white wire is usually a turn on wire for your amplifier for a subwoofer or all speakers etc. accessory is the red wire and yellow is constant which needs to go to constant from car side

Hi, I'm trying to install my after market radio and I have a couple questions. My car has a factory amp, so I had to order a special wiring harness for it. It is a common signal ground system with four separate positives and one common negative. Does this mean I wire the positives per usual, and connect the negatives to the chassis ground? That's the only open negative. Do I leave them unattached? What do I connect the phone mute wire to? And on my after market radio, the remote turn on (+) and power antenna (+) are the same wire- blue/black. On the harness, however the amp turn on is blue/white and the power antenna is just blue. Do I connect all three to each other in this case? Thank you in advance!

I have an internal antenna. Do I need to hook up the power antenna wire at all?
