Ok, so I got all the wires connected to the harness and tried it and the CD player doesn't light up or turn on. The only thing it does do, is if I hit the "CD eject" button, I can hear the motor run to try and eject a CD, so that tells me I have power to it. When I pulled the factory CD player out there were two separate pin connectors going in the back of it. One of them, I plugged the wiring harness into which connects to the new CD player, and the other one I have no idea what that was for, I was assuming this was the Onstar stuff, so it isnt connected to anything. I double-checked my connections and its wired up correctly as far as I can tell. I pressed every button on the CD player and I tried the reset button, and I tried pulling the face off and re-connecting it to make sure that was secure.
Anything I'm missing? Do I need to splice into one of the wires on the other pin connector that went into the factory CD player? Is there an external stock amp in this ca that I'm not aware of?
Any help is most appreciated.
