I just got a 1990 Cherokee and the previous owner decided to take out all four speakers and cut the wiring harness. I can currently find 13 wires and the antenna plug. I only intend on installing two speakers because I'll never be in the back and I don't have that much money. According to a wiring diagram I found, front right speaker wires should be black for neg and white for pos. I found 2 black wires and one plain white up in the dash. I pulled open the door panel and found one green and one black wire. So I looked back in the dash and I found a one green and one black wire. Went over to the left door panel and found the same thing. One black one green. I have another black wire in the dash but not another green one. According to the diagram left front speaker should be green for pos and black/yellow for neg. Diagram also says that the ground should be a black wire.
My questions are:
1) Does the color of the wires at the actual speaker matter? 2) Is there any way I can figure out which black wire is the ground? 3)Does any one know if you need a dash kit for this car? It doesn't look like the opening is too big but I don't have a radio to put in it yet.Any help would be greatly appreciated. Thanks
