anyone happen to have an interior wiring diagram for a 2005 gmc sierra RCSB?
mainly the steering column/ under the steering column area, im installing a SWI-PS Pac steering wheel controls adpter for his cd player and i need to tap into a wire to do it.

thanks!

 

which wire you looking for? I pull power from the radio harness and the control wire can be found at the radio connector too.

 

im lookin for the control wire, and in the instructions it says it cannot be pulled from connector

 

anyone?

 

Ill have to look on my avalanche tommorow and see where i tapped it at.
