When my serpentine belt broke, it ate the electrical connectors on the front of the engine. The replacement Engine Coolant Temperature Sensor connector I got had different wire colors than the factory harness. There was nothing left of the factory connector so I couldn't see what should go where. I'm hoping someone would take a look at their ECT sensor and tell me what color wire belongs in which position on the sensor. There are 2 positions next to the lock ear on the sensor and one additional position next to it. It sort of looks like this:

ECT Sensor looking towards block

[TAB] 3

Wires in the factory harness are yellow, black, and dark green.

I know this may be a pain, but thanks for any help.

 

I can look in the service manual, but what engine/year Mike?

 

I got the information I needed. Thanks to all who replied and/or sent info.
