harness was at the back of the amp (facing the amp from the hatch). I could not find it until I looked between the back seat and the cargo area. If you fold down the back seats, there is a flap that you can pull up. It divides the cargo area from the back seat. What i believe is the sat harness was taped to some other wires that are coming from the amp (u must get behind the amp). I hope this was it cause I'm getting my Sirius in a few day's. It's a white harness, can't miss it.
I'll get pic's during the install and mail them to ya.
