the radio control switch if the? I have already identified the 2 ports on the back of the radio that are used to allow the radio steering controls to work on the radio.
Why don't you just go to your Chevy dealer and get the wiring diagram from the parts dept.?
I have all the wiring diagrams. All of those involve the use of wiring harnesses, since I do not have the wiring harness that does have the steering radio control ports. I would have to order harnesses for the SIR to radio control AND SIR to the back of the radio.
That is why I am trying to get info on running the 2 wires directly from the radio to the switch.
