I’m not sure, but I’ll have to look at that diagram some more. That might be very helpful. I am still determined/curious to figure it out just for the sake of figuring it out.

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

You must’ve posted while I was typing. I really like that third brake light camera absolutely won’t work for my situation, though. Mine is completely obscured by my cap on my bed..

I’m sure I can look around but $400 bucks for the GM mirror is just not real

 

I just ordered the “WOLFBOX G900 TriPro Bumper Version 3 Channel Rearview Mirror Cam”

I may get additional cameras had a switch..

I’m probably gonna use some of this really good Velcro I use on everything so I can move the camera from my bumper to the end of my we which sticks out like 3 feet in front of my truck when it’s.

in the rear, I’ll probably put wood in the license plate bracket on my liftgate and when I take the liftgate off, I may have one mounted on the bumper license plate or from the ladder rack.. I may or may not get some 10 foot extension cables so that way when I remove the items I listed above, I can just plug it in and avoid the switch altogether or at least for the front

You just use the camera from the 3rd brake light. You can mount it in the cap. I didn't search for the best deals on the stuff i just got you the part numbers.

Hey, I wired up the backup camera for my '12 to have a separate switch to turn it on, on-demand, as well as come on automatically in reverse, and for my '04, I can select an on-screen button on the radio to turn the camera on, but both radios are aftermarket.  Both radio's have a harness adapter with a small computer that listens to the computer bus on the truck, to find out when the truck is put into reverse (and some other stuff), and breaks that signal out into a separate "reverse" wire that connects to the radio.  For the oem radio, that happens inside the radio.

This other thread mentions a '14, where WAMS might be able to reprogram the radio HU to be able to turn the camera on/off:

You might be interested in that.

I gave him that option already.  I feel he wants cheap and hard way not expensive and factory functioning.

Dude, that's super frustrating with your GMC camera! It sounds like you've done a ton of work. Since you know which wires get power, the two black ones are probably for the video signal, like one is video positive and the other is video ground. You might need to find a wiring diagram for your specific camera to figure out which black wire is which for the video to show up. Good luck!

It’s not that. I just thought it would be easy.
 

The set up I bought which should be showing up tomorrow was $350 and I’m likely gonna buy an additional camera and a switch..

 

It’ll be great for backing up and added security of having a video of people stealing my stuff

I had removed my rearview mirror the other week. I wish I had done it 10 years ago, but in my state, you have to have it to get an inspection sticker even though it serves no function with the cap on. Just like the third brake light on the cab I got a rejection sticker one time usually they just change your lightbulb for you, but they wouldn’t do it because the cap was on there and they didn’t wanna struggle to change the bulbs, even though the brake light can’t be seen anywhere other than inside the driver compartment reflecting off the front of the cap.

 

by having the back up camera in my rearview mirror, I also wind up with a functioning rearview mirror.. it should be much more convenient. I typically just park where I pull forward that way I never have any issue, but sometimes you do have to back up which I’d use the mirrors but you’re still backing up blind even with the factory camera you can’t see anything anyway, especially if I have any of my accessories in my hitch. That’s why I’m probably gonna mouth the second camera high up on the ladder rack.

I already had run a spare wire when I ran the massive cables for my front/rear mount winch.. I just thought it would be as easy as tapping in to the always on blade for the cigarette lighter fuse with a switch and connecting it to a wire in the rear. It didn’t work out that way, even though it didn’t work out. I just have a spare power wire for anything else. I wanna run back there.

[MGnoob]

I got a J fuse holder just like the regular fuse holder in the photo so now I have access to constant power and accessory while ignition keyed.. I just have to pull that 50 amp J fuse, put it in the holder and then make a harness.

I don’t think I’m gonna install a fuse block.

it’ll just be the camera system, and the trigger power for my light bar controller, and battery isolator.

[MGnoob]

Not bad.. just need to finish hard wiring, connect GPS, program it.

 

I got Velcro on multiple places on the front. I can just move the camera around.

 

on the back, I’m undecided if I’m gonna install another camera probably

 

The rear camera has a red wire coming off of it that you hook up so when you put in reverse, it comes out automatically.

 

I just have to tie that to the white wire from the existing factory camera. Apparently, I learned that the hard way.

I ended up using the information from this thread
 

 

 

I used fuse 32 and 36 to tap off of. I think I had it backwards the first time because it was constant on. I just switched it and it seems to work fine. Other than that,The mirror says battery low one time and then another time it said battery level very low, but my truck doesn’t tell me any of that… I haven’t noticed it since I’ll have to check tomorrow

 

I swear, I thought I heard it making a noise when walking past it a little while ago while it was off, but I can’t be sure I didn’t have my hearing aids in.

 

I’m still using the accessory blade from where you would move the 50 amp cigarette lighter fuse if you wanted it to not constantly have constant power to charge your devices from for other stuff.

 

later today, I’m gonna be installing the smokers kit and swapping out that socket for a cigarette lighter installing the ashtray. I’m likely gonna hardwire in a quad lock mount/charger for my phone at some point…

I haven’t decided where I’m gonna get power from for that yet. Possibly a different location altogether. Currently drawing off the accessory for the cigarette lighter I have a three amp fuse that runs to both my battery isolator and my lightbar controller. I know I got a lot of extra wire, but I just always do that.

because I had repaired where I had cut the wires on the original back up camera, I peeled back the shrink wrap and bloom. One of those wires is literally just glued together from the factory, but yeah, I tapped into the white wire and all is good for reverse.
