Re: If my truck has a temp gauge does the temp light function?

Just find a no gauge harness and pull the wire that runs the light. Add it into the gauge harness. There is an empty spot for it. In the engine compartment same thing on that harness. Then run both the temp and oil senders to the same wire and you have your check engine light.

I'm going to see if I can find a way to wire an oil pressure warning light switch to the currently unused temp lamp. Shouldn't it be as simple as wiring a oil pressure switch to the unused pin 5?
