Ok, here's my situation. As some of you may know, I got my supra last week Monday. I want to put in an aftermarket radio. Problem: The Sony aftermarket that was installed was installed improperly. No wiring harness, they just cut the wires. So, I have a plug that's just hanging, wires connected directly to sony wiring harness wires, and the speaker wires were connected through an amp... A crappy amp. Basically what I'm asking is this: Does anyone know how to wire a pioneer DEH-34 radio in to an 85 Supra? The speaker wires on the car side were connected through an amp, and I don't know which ones go to which wire on the harness. The other wires (positive, ground, dimmer (I think)) are all connected through the wiring harness for the Sony deck. I am hoping to do this maybe tomorrow or Friday, and am going to check Pioneer's website (if such a site exists) to see if I can find anything out there. Help if you can, I would greatly appreciate it!
