I have a 2000 gt coupe with the mach 460 audio system and I want to replace it with an aftermarket receiver. I have pulled the factory deck and hooked up the aftermarket deck with the wiring harness' supplied. The problem is that every wiring harness that I have been able to find does not have a connector for the 6 pin connector. With this being said, I have power to the deck, but no sound because I don't have the six pin connector hooked up. How or where do I wire in the six pin connector? What I have done so far with the wiring is....gray plug to the deck, ant to ant connection, 8 pin to speakers, black ground wire to ground, 6 pin to ?.....HELP!
