I’ve researched this for 10 years and I finally got around to doing it. Nothing on the Internet seems to help.
 

This is a 2015 GMC Sierra 1500 WT

So here is the deal there are 6 wires that go to the camera.

IMG_6434.thumb.jpeg.b2d6ebf5860d6465486d5feca10d23c7.jpegRed, white, yellow, brown and 2 blacks

Red wire is constant 12+ volt.

White wire is 12+ volt while in reverse.

 

If you apply an external 12 V source to the white wire the backup lights do come on, but the camera doesn’t. If you cut the wire, you can eliminate the backup lights, but the camera still doesn’t work.

 

The yellow, brown, and two blacks have no voltage or negligible voltage, whether in reverse or not.

 

I’m assuming my problem has something to do with one of the two black wires but I don’t know what it is.

 

What am I doing wrong/missing?

 

The goal is to install a diode, so the camera works in reverse and when a button is pressed in the cab. I already have a wire in between the cab and the Camera. But that’s pretty useless until I figure out how to trigger the camera on… I’m going to take power from the driver side fuse panel, where I have my other accessories connected so it’s only live while the truck is keyed on.


Help would be appreciated.

To close this out. I didn’t have the wires backward . I had to put them back the way they were.   IT works absolutely flawlessly now, short of a voice command for the bumper camera, but when

Why would you expect the camera to tell the radio when to flip into reverse mode?  I expect the radio receives a digital signal from the ecm/bcm telling it the truck is in reverse, then the radio goes into reverse mode and turns the camera on.

 

I would expect it to be non-trivial to get the radio to switch into reverse mode on command.

 

But, if you really want to find out, a subscription to alldata.com should be able to tell you what all the wires to the camera plug are for.

I feel like it would be easier to just do the live view rearview mirror the hardest part of figuring that out is how to mount the camera. It you have auto dimming drivers mirror you'll already have power to the rearview mirror you'll have to get a mirror from a 2020+ truck and you'll have just the camera wire to run to the back of the cab. If you don't have auto dimming drivers mirror then you'll have to get a harness from harnessdr.com. all in all way easier then what your trying to do.

That’s not a bad idea. That is what I’m trying to achieve. I have a cap on the back of my truck that completely blocks my rearview..

You can get the camera cord on Amazon it comes in several lengths.  Camera and mirror is off a 2020+ truck.

Why would a wire from the camera that is triggered by reverse lights, not turned on the radio view? what purpose would it serve?

 

I have read there’s a 20 pin connector behind the radio that you can work with, but that’s for upgrading to a new radio/viewer.

 

they sell kits that you plug directly into the camera that jumps the remaining 5 wires together, but then it only has an RCA, which is video and ground that you plug directly into your new radio. I would just cut that off and connect it to the existing wiring but that my not work. My radio has no option/menu for the camera at all.

I should attempt to try jumping the remaining four wires that I’m not working with together

not the red or white though and see what happens if anything it would leave me with the camera/video monitor constantly on. then I would just interrupt the power on the red to turn it on and off.. I would lose it automatically coming on when I put it in reverse.

I’d still like to get the rear camera to work similar to the way I’m doing it, but I guess I could always go cheap like this..

I don’t think I have any power up there, though I guess I’d have to figure out how to route it

I guess with the adapter from Amazon and the camera package from eBay I have both cameras on my rearview mirror. I can probably make it work so that the factory system still works.

I added all the things you need for rearview mirror setup. I put this in my 2014 and my 2018 sierra's

I’m dumb. I should just buy this. I’m operating off of what I tried to do 10 years ago. I didn’t realize I could just buy this. I’ve recorded front and rear view. Forget the factory system.

 

i’m gonna look into these and the OBD-2 options…

if anyone knows how to make the factory one work the way I want to please tell me.

 

this is similar to the controller. I got for the LED light bars. This modern stuff is great.

You can also upgrade your radio HMI to allow carplay and android auto and then get this adapter harness so you can push a button on your radio screen and turn on the backup camera while driving down the road.

I just gave you the 2 easy plug and play options that everyone does. And have personally done myself.

      Intermittent no-code issues on 2022.5+ V8 trucks — what did the shop fail to capture?

      By asilverblazer · Posted

      Length/amount of data capture will be important to consider, sifting through 5 minutes of a data log can be enormous when it is stored in milliseconds. Being able to find the 'event' let alone decipher it.   Presumably the driver would notice something and hit a button to capture the 'window' of data. That window has to be large enough for the operator to recognize the event and react accordingly.    The data has to be able to be retrieved easily.   The data has to be able to be understood. Which is the biggest challenge, dealer techs won't even know what most of it is and would likely not even look at it if an owner brought it to them. Meaning the owner, the least educated/qualified, trying to understand it.    How will the data be presented? Could specific PIDs be selected and a timelapse graph be watched? How will a specific value be noted as abnormal? Additionally, a good data logger would be able to 'learn' normal values for a specific vehicle and flag abnormalities automatically. It could in theory watch parameters degrade over time and suggest maintenance as needed. (If the MAF reading begins tapering off for a given set of other readings - MAP, throttle position, Ambient, etc.. a flag to check air filter.) With the amount of data available, a device (really the vehicle rather than an additional accessory) should be able to do more than issue a DTC. It should be able to run the full diagnostic suite automatically and present a solution rather than a code. (It's not the 90's anymore). The technology is available for the vehicle to not just say "P0087", it should know low fuel pressure, check other PIDs to narrow down the problem itself, and determine if it is a lift pump, high pressure pump, regulator, leak in the fuel line, clogged filter, etc. Even if it can't narrow it down, it should be able to guide the user to the likely problems.   This would be a major problem for dealer service departments, which are the manufacturers customers it is in their collective best interest to NOT have this available to the consumer.   Further, if the owner is going to be the primary consumer of the data, it's got to be at a consumer price point vs. dealer only specialty tool price.   This group is more 'involved' in their vehicle than general public/consumer and will have knowledge, experience, needs and desires that are quite different from the market at large.

      OCI, not when but why?

      I put the prof up. If you read what I posted. You can see that housing, cars and income are in line with the era we were talking about. It’s harder in some places easier in others. Let’s agree to disagree and put this back on track, OK? We both are pretty stubborn and hard headed. But I bring receipts. If you wish I will not respond to you in the future.

      Lets see if I can sum up two pages of nothing useful.    You want to refute your own governments data of the "Purchasing Power" Index FOR THE ENTIRE USA and its territories replacing it with the experience of a single family and its business and label that reality?  Then pound on that for a week hoping it will find traction?    Stan, I've told you several times. I don't do irrational. There are more people in the USA than your family.    I'm pretty sure this tread is so blown up. I'll give you a few days or months if need be to post yourself silent then I'll see if I can find enough parts of the train to reassemble it.

      VSE CCV Bypass - Anyone have this installed in their L5P?

      By asilverblazer · Posted

      Facebook groups hate VSE, poor customer service; their responses to criticisms are pretty poor for a reputable company. I'm not a customer, haven't bought anything from them, but how they handle themselves on social media is a definite "No" for me.

      Transmission Woes :-(

      By asilverblazer · Posted

      $10,000 for a transmission?   Pretty sure I could buy all the parts, tools, and education to rebuild it myself for a quarter of that amount.   or swap it out with a new one...
