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.

Another site for camera options in case you want to add front and side cameras.   https://www.camerasource.com/automotive-backup-cameras?make_filter=6012&model_filter=6204&year_filte

You can look on this site maybe find what you're looking for they do have a switch option for multiple camera angles.    https://navtv.com/

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 bluev8 · Posted

      That makes sense, and I think you are describing the real product problem. Capturing data is the easy part. If the owner or technician has to manually dig through five minutes of millisecond-level logs, the product has already failed. The device would be at the ECM harness, not at the OBD port, so I agree that data retrieval and event marking need to be thought through carefully. The way I am thinking about the architecture is: The recorder itself should not depend on a phone, app, Bluetooth, Wi-Fi, or cloud connection to capture the event. It should always keep a local rolling buffer and lock the event locally. A button, phone app, or small cabin device would only act as an event marker. If the driver feels a stumble and presses the button 10–30 seconds later, the pre-buffer has to already contain the useful data. For data retrieval, the practical options would be a sealed service USB lead, Wi-Fi download, or a phone/cabin companion device. I would not expect the owner to remove the ECM-side module or work with raw files directly. The cloud or AI side would be for interpretation, not for capturing the event. The truck may have no connection when the issue happens, so the evidence has to be saved locally first. After that, cloud processing could help decode the data, compare it against baselines, and generate a readable report. For the first version, I would keep the automatic triggers conservative and objective: driver event marker bus-off error passive voltage drop / brownout device reset FIFO or queue overflow a normally periodic message disappearing side-to-side communication mismatch, if the topology supports that For “learning normal,” I agree with your point, but I would not want to overclaim it as automatic root-cause diagnosis at first. A realistic first step would be learned baseline comparison for that specific vehicle and operating condition. For example, a value would only be compared against similar conditions: RPM range load / MAP throttle position gear / vehicle speed coolant and oil temperature battery voltage AFM/DFM state, if decoded and validated Then the report could flag things like: this periodic message disappeared compared with its normal timing this value deviated from this vehicle’s normal range under similar conditions the same abnormal pattern repeated after the same type of event the anomaly occurred together with voltage, oil-pressure, misfire, or communication changes But I would still call that “abnormal pattern detected,” not “replace this part,” unless there is enough validated repair data behind it. So the intended product would not be “here is a huge log.” It would need to be an event package: what triggered the capture how much pre/post data was preserved what changed before and after the event whether the device itself reset, overflowed, or saw a bus error selected graphs around the event raw data only as supporting evidence From your perspective, what would make this kind of report useful instead of just another datalog? For example: What are the top 5 parameters or events you would want highlighted first? Would you trust a learned baseline for that specific vehicle, or would you prefer fixed thresholds? How much false-positive flagging would be acceptable before you stopped looking at the reports? What would a one-page report need to show for an independent shop to take it seriously? For misfire, AFM/DFM, oil pressure, or U-code complaints, what would you want the tool to flag automatically?
