Trying to install a new head unit in a 03 Silverado without Bose or Onstar. The truck had a kenwood deck in it already, so I am not sure of the wiring harness. Looks to be just a basic GM one. I hooked everything up to the new decks wiring harness and pluged her in and all I got was the cd eject mechanism to make noise. No lights, no sound. I am stumped, where can I start? I think a wiring diagram would help, but I need one for the truck side of the harness. Thanks!

Check YELLOW wire on the deck for constant 12 volts and RED wire for switched 12 volts and test BLACK wire for ground. If all these are OK, then check fuse on deck.

Yep, these trucks don't have a switch 12v source.
