Hey Guys I am needing some help with some wiring for a 2005 GMC Sierra. I was planing to put amy after market cd player in my new truck. The problem I am having is how do you wire it right. I wired it all up the way I thought it would be and ends up I could not start the truck. I would just shut right back off. So I took the back out and put the radio in and it worked. Is there something I am missing or need to do? Thanks

1. Did you use an aftermarket wire harness?
2. If yes, did you use the acc wire in the factory radio plug?
If you did, you may want to try running a new acc wire.
This may be the problem, but i'm not possitive. Many times the factory acc wire is a pulsing wire to turn the radio on.
Need more info: does the truck have On Star and/or Bose Speaker system?
This truck has no acc wire ( switched 12v) in the radio harness. It is a digital signal on the Class 2 Bus that the radio sees & turns on. Most likely from your description, you do not have the right harness adapter. Also the factory radio generates the warning chimes ( low oil, headlights on , key in ign, etc...). You need these to work! Soundgate, Scosche, Metra & others make the right adapters w/chime generation, OnStar & Bose interfaces, and a decoded acc lead . Example -
No Bose or Onstar - Soundgate GMCHIME or Scosche GM09
Has OnStar, no Bose - Soundgate DIGISTAR
Has Bose & OnStar - Soundgate DIGISTAR-X
( I sell Soundgate, so I know it best...)

Experience gained is directly proportional to the amount of equipment destroyed - break it & learn!
yea, if you have the wrong harness, then you will have the DATA wire going to your radio power input, this will ground out the data output, and totally confuse the computer, it will read brake trouble codes and all sorts of crazy shhh, you need to get the ch09 or something like that, the chimer modual for the databus 2 system, it's like a 50 - 80 dollor part, depending on were you look, doesn't sound like you have onstar or anything.. i think their systems act a little different, but i dunno
