I have the Mach 460 in my '00 mustang coupe. I have an aftermarket headunit, i have every wiring harness i can get my hands on....even the harness from Metra....the harness going into the middle of the stock radio(top DIN) is the power for the unit. Then i have two grey harnesses and a black one. im guessing one of the harness connects the CD player(bottom din) to the radio and that the black harness is power? I need to know how to find the speaker wires, amp wires, etc....wiring diagrams would be great!! anyone that can help please do, i have lots of wires and im not sure where to start with this. Plug and play, no way, not even with the metra harness, i cant even tell where those connectors would plug into even if they could

 

breath in, breath out.........

check out page 2 of my sig and see if the hrns's look the same.

One hnrs is the power, one it the connector for a slave cd, and one is for the audio. There is actually a forth as well that you may need depending on what you want to do and what deck you bought. Are you going to add any other equipment in the future?
