backup camera wiring

17845 Views 28 Replies 6 Participants Last post by  ofl0926
hello everyone. so i am attempting to installing a camera for my truck. the camera comes with a red(+) wire, black/red(-) wire and a yellow RCA connection. the back of my radio in the harness, there is a wire labeled reverse gear signal input purple/white stripe.
i ran the yellow rca to the headunit.
now for a few questions

do i run the red wire to a constant 12 volt?
if i do need a constant 12 volt, where do you suggest splicing into?
black/red will be ground
the purple/white stripe wire, is that the one that needs to be wired to the reverse gear signal AKA the green/white stripe wire?

the truck is a 12 crew cab with RF system. headunit is a pioneer avh-x8500bhs

thanks again

If you run 12v constant it will always be on. When I did mine on my 06 I tapped the towing harness for the reverse light but you need to tap the reverse wire to the deck as well. I ran the wire all the way back from there with the rca. There is a post somewhere on here you can tap a wire under the dash would be way easier (I couldn't find it) for the deck. I had an amp under my back seats I used power right from the battery, but used a relay and the remote wire to turn it on when the head unit came on. It worked.
Yes the purple to the green. You can use any 12v wire that only has power when the truck is on (not much in the back) for the red and you can ground to any bolt on the frame underneath.
I wired my camera always on when truck is running and then ran the reverse 12v into the video switcher. I also ran an additional 12v source from a toggle switch to the video switcher so that I can activate the camera without putting it in reverse if I'd like to.
Any recommendations to which 12volt constant I can tap into that is towards the rear. If I have to, I'll run cables to the inside.

You could tap the reverse light it would only have power when it was on. Unless you want to go with the whenever want route.
You have to run the RCA to the head unit so run your red power wire with it and tap into the power going to the head unit.. Should be the read wire.. Easy.

The camera should have power whenever the truck is on otherwise it will be dead if you hit the camera input on the head unit (to check trailer or for what ever reason you may need)

Copy that amigo. Thanks again everyone

You probably also have a wire that has to go to the parking brake for DVD playback there is a relay jump out for that if you look it up (it's illegal to drive with one playing). I did it so my kids could watch a movie on trips though.
well i tried everything you guys recommended and no luck.
here is what i am doing


pioneer avh-8500bhs

red wire from camera to power of radio red or yellow?
black/red wire to ground
purple/white stripe wire from harness to green/white stripe wire on passenger side kick panel
yellow RCA from camera to RC IN on radio

well in the settings i have options. i have the polarity option which gives me two options positive or ground. the other setting is camera on or off. if i turn the camera on, it activates but doesnt turn off. it stays stuck in the camera setting and i have to hold the mute button down to get the picture off the screen. if the camera setting is off, nothing happens. we tried different things and my friend and i are stuck
if someone could just break it down simple for me so i can get this down, i would greatly appreciate it

You are combining two modes of operation together, hence the 'strange' operation.

The normal mode is that the camera is only on (and viewable) when the transmission is in reverse. In this mode the red wire, camera sense from HU (purple/green wire) and back-up wire (white/green) should all be connected together (do not connect the red wire from the camera to the red wire going to the HU). Camera polarity should be set at Positive.

The other mode is for the camera to be on full time and the HU is switched to camera input (camera ON) whenever its display is desired. In this mode the red wire from the camera is wired to a permanent power source (such as the red wire going to the HU) and nothing is connected to the white/green wire in the cab (back-up light power source). Do not connect the purple/green wire from the HU to anything.

You do not need to make any change to the ground connection and the video lead.

Proper connection is the red from the camera to the red power wire of the head unit, the green wire from the Headunit to the backup light wire in the kick. The green wire HAS to be hooked up or it will not auto switch..
The Pioneer is flakey you have to play with the settings to get it to work, but it will.
If you don't hook up the green wire from the HU to the kick you manually have to switch to the BU camera, and if you don't connect the camera red wire to the a wire that is switched by the key you won't be able to switch to it whenever you want. It will work.

It's thing, use a meter and make sure the Green wire is getting 12v only when in reverse. If so I will check the settings on my buddy's pioneer and see how they are set. I swear I hate pioneer.

well no luck my friend. i didnt have a meter to check the voltage. i did have a test light and it did turn on when i applied it to the green/white stripe wire
That it then.. Should just me a setting in the radio
This is too late to help you, but if anyone comes along and reads this because they are considering doing what you are attempting......Peak makes a really good wireless backup camera system. After two wired systems failed on me, I came across the Peak at NAPA for 79.00 and the guy I work with there said he hadn't had a single one returned for any reason. Installed it in less than 15 minutes, it does what it's supposed to and hasn't failed in one year of use.
Wired cameras are not hard. Pioneer radios are. Lol

I really wish I did the research on the pioneer before. I did get a great deal in the radio from my friend

I'm thinking of going the wireless route. Just don't need the lcd. We will see what I do. I was really hoping it would work cause it would make life so much easier for when I hook up to my boat

I have a Pioneer HU in my 2013 Titan and have no problem with the aftermarket rearview camera. I have it wired to automatically operate when shifted into reverse. I did not try to wire the camera permanently on such that I could use the RearView selection to manually display the rearview when desired as well as work automatically when shifting into Reverse, but it should work that way if the camera power is connected to a permanent source of power instead of the backup-light circuit. The camera sense should be set to Battery in settings.

Try again with camera power lead connect to the red wire going to the HU (or some other source of power that is on when the ignition switch is on) and the HU sense wire is connected to the green/white (backup light) wire. Camera ground is connected to chassis ground and video from camera to camera input on the HU. Connected this way the HU should show the rearview when the transmission is in reverse or when the RearView is selected on the HU.

Just to clarify. It will work perfectly with the pioneer. It just a setting in the menu. We had the same problem in my buddy's Z. I'm trying to catch up with him to get you all the settings.

Eakes. There were 3 or 4 backup camera settings. Can you see how all of yours are set..
I have two settings for the backup camera: In settings for Camera there is a choice of Battery, Ground and Off, is set for Battery. Under Video Settings (sub menu to Settings) the choices for Camera are Auto, On and OFF, set for Auto.
