I ave completely replaced the mach 460 sound system in my 95 vert. Im finishing the wiring for the receiver/CD and have a question. Should I connect the ground wire of the receiver to the ground wire of the wiring harness adapter -- or to car metal?
I'd use the one from the harness if it were up to me, but I don't think you could go wrong in either case. It's probably easier to just use the factory ground, versus finding a good ground anyway, since you need bare metal to attach to, and you'll probably be digging around under the dash to find it.
