I think the previous owner of my TTA had an aftermarket stereo in the car. And the radio works now even with the key in the off position. I think it might be a bad relay that the guy installed. But I wanted to find out what one of the wires in connected to. It goes in the far top right spot on the far left cluster of wires on the passenger side behind the dash. Here is a pic if that helps. The wire was gray with a blue stripe.
Also let me know where a good place is to get detailed wiring diagrams.
TIA
