Larger two pin with connectors in a tee, pointing forward, is the ecu ect sensor.

Smallest one pin is a thermoswitch to control o/d shifting.

Medium one pin is gauge sensor.


That's interesting. My truck is a 5-speed. I can see someone, somewhere along the line, installing the automatic's tstat housing/manifold, but then why do I have all three connected? <img src="/forums/images/graemlins/pfft.gif" alt="" />

Thanks again, Eddy.
