I recently removed the rear lift gate speakers in my 89' but I cant seem to figure out what wires are for what in the panel behind the spare tire mount. I want to relocate the gate speakers to the cup holder area in the back seat. I can see which one goes to my trailer hitch plug but thats about it. Can any one give me a hand on figuring this out? I also need to replace my lift gate soon so any info on doing that will help as well.
