I have a 1986 toyota pickup with wing windows and a pocket below the stereo, and I'm trying to install a new Pioneer radio for it. All the cords in the toyota pickup are different chords than what they are for the new wire harness i'm trying to install. I'm trying to figure out which cord is the one that will turn it on and the cord that connected to the ignition. I'm really confused and I don't want to buy an adapter for it because I'm converting the pickup into a four speaker system.
