ok, well, before any one says that I should just get an aftermarket cd player, and rewire it all now, this is what I got, and it was all free, so I'm going to stick w/ this for now at least 
I'm attempting to remove the stock mach 460 wiring harness behind the headunit, and add a different type, w/ new wiring and an add cd harness included. not to mention, a new ground (I'm getting interferience now
) so, I can remove almost all of it, but that little clip (w/ the yellow wire on it) is giving me a ton of trouble! it's way up in the dash, behind the gauge panel, and the steering setup is getting in the way... any suggestions? also, does anyone know where the harness from the front, connects to the rear harness wiring? that would be helpful to know too, along w/ where that ground wire actually is connected to the frame (the one about a foot in the wire before the connection between the two harnesses is made. thanks guys.
