Just bought an Pioneer AVIC D3 for my 2002 Cab and cant find the harness that will work for the car. Crutchfield and other online sources have not been helpful. Can anyone recommend somewhere i can get a harness[X(]

 

if you have the old 8 pin harness one brown and one black then use a VW, test the wires for the power side though, if it has the little yellow one inthe top corner that looks like it is from a lego, then that is your speakers to your amp including amp turn on which would be the lone wire not teisted like the others.
