What coolant temp sensor are all of you using? The one on the back of the Water pump (not the single wire sender) or the one on the driver side bottom of the Rad? Im about 2 hours more work of getting the car ready to start (some OE wiring bugs and button up some things) and just a little curious on what you all were using.

 

Use the one on the back of the water pump.

 

Thanks Ken. After going over my diagrams AGAIN, the one on the rad is for a fan. I gotta build that circuit eventually. I got my Taurus Efan on a toggle switch for now.
