We are trying to replace a stereo in a 2007 pontiac montana sv6, but we can't find a wiring diagram anywhere. Unfortunately the previous owners took off the factory harness. We believe we have most wires figured out but there's a couple we are unsure about. The constant 12v and the switching 12v we keep finding contradicting info on. Thanks for your time

There is not a switched wire in the radio wiring. It is data controlled. Constant is probably orange. The data wire is probably pink. Do not connect anything to that. Insulate it so it does not touch anything. Is there an air conditioner control near the radio? Are there 2 plugs on that? Does one of the plugs have 6 or so larger wires? If so, the brown wire will work for a switched power source. If both plugs have smaller wire, there will be a pink wire that you can use. Use a meter to verify.
