    Default Need Non-Bose Radio Wiring Diagram for 09 Silverado

    I have been looking everywhere for a diagram of the OEM connectors behind the factory head unit. I have an aftermarket radio and i'm not spending the $150 bucks on the onstar/chime adapter which is apparently all they make for my year model. SO i'm gona just cut the oem plugs and splice em together with some good connectors.

    Anybody have the factory wiring diagram for the 2 factory plugs?

    metra doesnt seem to make one without the $100 adapter. All of our local shops use metra, and i've looked at em with no luck.

    why not cut factory wires, its the way it used to be done back in the day before harnesses.

    i wouldnt cut the wires. as soon as you do that you void any warranty you have left on everything electrical. Plus in the long run, the $100 you spend will be worth way more than the headaches from a head unit just dangling in your truck because you cant figure out which wire is correctly connected.
