The temp. sensor thats in the pass. side head has a wire that comes from what wire loom? As many times as I've had this thing apart, I can't find the wire. I've gotten under the car and just about stood on my head looking for it. Any help. Thanks.

Actually it's the fan sensor, not the temp sensor.

 

I just found mine it was comeing from the driver side by the washer moter . Darkgreen whith prong to go over sensor . My temp sensor was on the drive side head that other one put me on the wrong track for a long time .

 

On my '88 the connector for the Heavy Duty Fan Switch on the passenger side head (Gray wire) runs in the same wire loom (along the passenger valve cover on intake side) as the Injectors, Knock Sensor, TPS, CTS, CSS, IAC, A/C, A.I.R. Solenoids, and Starter. It has the same type of connector as the Knock Sensor.

The green wire on the drivers side is connected to the Engine Temperature Gauge Sending unit.
