So every thing from my avic hooks up to the mach 460 head unit wiring harness i just dont know were to connect the amp turn on wires (2) from the car to the radio and in im just going with the amp grounds(2) just gets grounded to the car
Connect the 2 blue/white wires to a 3k ohm resistor, and then from there to the blue/white on the D3 harness (it's with the RCAs).
Also, did you connect the pink from the radio to the white/orange wire in the pass kick panel? It's the VSS wire and will make it more accurate. I have done a few installs without the pink connected, and trust me, you want it connected.
