Question Wiring diagram?

Does anybody have a wiring diagram for the harness going into the back of the factory radio? (Pioneer equipped)

When I installed the Pioneer flat screen head unit in my 2007 LT2, the "LAN adapter" that I bought with it had the plug on end for the head unit and the correctly colored wires to connect to the factory wires. It required me to cut the stock plug(s), solder and insulate the connections but wire colors matched exactly.

Should be fine, factory wiring to the door speakers is decent. Over 100w I'd consider upgrading.

If the adapter does not have it the radio is not equipped for it.
