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.

Whatever you do, do NOT cut the factory wiring off. Please... There's reasons that the module exists. With these newer trucks all the wires are not directly derived from wires in the dash due to the advent of computers and CANbus wiring. You might be able to scrounge up the wires from various parts of the truck, but do yourself and future owner of the vehicle a favor and get the module. You'll also keep the door chimes and other critical alert and safety chimes, which you'd lose otherwise.Christopher

Thanks for all your help.
I ended up not going with that expensive adapter and instead went with a Metra 70-2105 harness for 2006 and Up Impala. Fits the OEM harness and only cost $15. Of course now i don't have the annoying door chime, and the onstar which i never used, but at least if i ever wanted it in the future i could also add the adapter.
I still soldered and shrink wrapped all my connections, just didn't have to cut the OEM harness.

thank God you didnt cut the wires, there are aways around situations like that and what you did will work fine. just dont cut the wires. And the wiring color code that the member gave earlier is accurate as far as I been doing mobile audio for the past 15 years. GM has not changed there color code in decades. Hope the new radio works out for you. What are you putting in there anyway?08 Silverado

Install went well, only issue i ended up having was finding a "safe" 12v accessories source inside the firewall, But i ended up finding one on the power block near my brake pedal. Apparently GM leaves a 15amp and 30amp accessory circuit there with an ignition on/off circuit.
I also installed a hidden ground switch so i can bypass the dvd player parking brake crap.
