The temp light in my dash is not working. I don't beleive it has in the 15 mos. I have owned the car. I have a sending unit? mounted on the intake with no wires connected. Where do the wires for this originate? How do I recognize them? I have just had my engine rebuilt by Brent Hougestol at Advantage Custom Engines in Didsbury Alberta and am very happy with the result. But I cannot drive the car with confidence until I get this silly idiot light working. The car is a 67 326 2 speed. Can anyone tell me how to get this temp light working PLEASE. Jimbo
