I am having all kinds of problems with the VSS signal wire on a 2007 chevy express van. I have been told that it is a dark green with white stripe located on drivers side pcm under hood. I found 5 wires with that color. I have tried all of them and still get strange readings on D3. What numbers should I see on the connections screen. The unit show the car driving 50-80mph when I am driving 10 mph. I also read that the unit takes time to calibrate. How long does it take or is it by miles driven?

I finally found the wire. It is dark green with white stripe on pin #50 on pcm under hood drivers side fender.
