My "new" Truck needs a little help: 2010 Chevy 2500HD

[UNSTUCK]

After months of searching, I found a nice-ish 2500 HD CNG truck. I pulled the trigger on it and drove it home on Monday. The place I purchased it from is being pretty cool about a few items I found that need repair. They are willing to help out, to an extent. I can take care of almost all of it, but the one issue I'm stuck on is that the reverse system is not working. No back up lights, no back up camera and no back up alarm (when you are close to running into something). I found a broken wire at the camera and fixed it and thought that would fix my problem. No such luck. That is when I noticed that the lights weren't coming on either. I though maybe the switch on the tranny was bad, but this new tranny doesn't have the Neutral switch that the older 4L..... trannies had. I haven't been able to find much about this problem online. I did verify that the back up camera switch is turned on (button on the mirror) and found the reverse lights fuse, which was good. I also noticed I have no power to the reverse lights at the trailer connector.

So, anyone run across this? Or maybe you could point to one of the better chevy forums that I could get some information on this issue.

Thanks.

WOW... sounds like a crazy issue that is being caused by one thing not turning on. Good luck on the search. Look up fullsizechevy.com I know there are a few chevy techs on there that might be able to help.
