so i have a 87 yj... and i am trying to install a aftermarket deck in it. and i cant find a wiring harness anywere because it seems that the 87 is a one year wonder for a radio wiring harness. so i have to do it the cheap man way witch i dont like doing and cut the harness off the back of the old radio and make my own.. i was just wondering if anyone has done this and could tell me what wires mean what... and i am also install rear speakers and it seems to look like the front speakers are dual voice coil speakers so what wires do i snip from the back of the front speakers and wire them to the back speakers.
