I recent bought a 1985 Mercury Grand Maquis, and want to install my stereo from my old car. I have a JVC KD-S10. I have the wiriring harness for it, but I am unsure of what colors goto which cables in order to install it, and I'd rather not dish out 35 bucks to have it installed by someone. If anyone can help, please do. I am dying without having music in my car.
