Need a Pic

[scottKP]

I need a pic of the ecm still plugged in. There is a white box piggybacked on side of the ecm (calibrator). There are two plugs. The bigger one has several wires. I need to know how many wires (and colors) are there in the smaller plug. Also which ports they are in if more than one.
TIA

The larger plug has 6 wires (blue, purple, black, yellow, black, and green). The smaller plug only has 1 wire. It was dark out, so don't quote me on the colors.......but if the wire count is the same, I'd bet on it being okay.

Thanks Hood.
Here's my problem: My speedometer works fine, but when I hook the scan-tool it doesn't show a speed reading. Therefore no T/C lock-up, etc. Does anyone know how the system works? I am guessing a signal comes from the VSS into the calibrator. It does it's thing then sends it to the cluster and to the ECM? So I guess my VSS is good, and I have tried another calibrator. Could I have a cut, grounded, or bad wire somewhere? Any thoughts would help.
Thanks
