Well I had time today to look for that dark green with a white stripe. I found @ least 5 of them. How do I tell which one is the correct one? I am trying to hook up a Pioneer Navigation unit that requires this VSS wire, I tried the first GREEN / WHITE and no go.

I believe the VSS wire is in the green plug of the PCM in position 50. The green connector is the one closest to the fender and you usually need to remove the one closest to the motor to get it out. There are 7 mm bolts that secure the plugs in the PCM.

Yep that was the one, I had to pull the whole controller out to get access. Pin 50 was the correct wire.

thanks a bunch
