I'm looking for the VSS and reverse wires for a 2000 Explorer Eddie Bauer. It has the Mach audio system. I've searched the forums, and some people say it's only in the big wiring harness on the passengers side of the engine bay (grey/black). Others say it's in the radio harness, but I dont' see a grey/black wire in there. Can anyone confirm either way? There is a 20-pin connector for the stock radio, but I dont' seem to need it for my D3. I thought maybe the wire was in there, but no grey/black. Anyone have a pin-out of that connector? Also, where is the reverse wire for the backup cam
