thanks guys,
I found a harness of wires coming into a rectangular plug on the passenger side behind the side panel under the speakers. Could this be it? I was kind of hoping to find a couple of rcas actually but realized that wouldnt make sense after I thought about it. If so I guess I need to figure out which are right and left input. I don't intend on having any control or power from the head...that would be nice, but more than I want to chew off at this point.

take care, opossum
