1995 Mustang GT Mach 460
I have a 1995 GT vert that originally had the Mach 460 installed, but had an aftermarket hu installed when I bought it. I purchased the Metra 70-5510 harness to see if I could integrate the factory amps. What is interesting is that there are 2 harnesses in the dash that the metra harness will hook up to. The one the hu was already hooked up to does NOT have the orange (dimmer) or blue (amp turn on) wires in it. The second harness does have these wires, but there is no power to it at all (I verified with a volt meter). Does anyone know why 2 harnesses, and if so, why only 1 works? Will hooking up the blue wire from the radio to the other harness make the amps work? Is it worth screwing around with, or am I best off running everything new? If I run new, how should I set up? I always wanted to do a component type set up, but not sure where to start.
Thanks in advance for the help!
