Well, I have replaced both my tcc solenoid and the external wiring connector, and still no lock-up. Is there a way that I can test the wiring to see if it's getting the signal from the ECM? If I turn the key to "run" and jumper the pins at the ALDL will it send voltage to one of the pins at the connector? I'm almost out of ideas here.

the power wire on the four pin connector is towards the drivers front. you can back probe and test light it. again left front is power (otherwise known as pin A.)

I tested the pins on my tcc solenoid connector today.

With the ingition turned on and the A and F terminals jumped I got voltage at all three pins. When the brake peddle was mashed the voltage at the purple wire went to zero, I assume this is correct.

When I removed the the jumper wire at the ALDL the tan wire went to zero and the green wire was unchanged. Shouldn't it be the green wire thats goes to zero and not the tan one?

Anybody? lol

One more bump. Anybody know if these results are normal?
