Help With Sensors

I am rebuilding a 72 C10 and I have found 2 sensors that I don't know where they go. They are both the same thread pattern - I am guessing on is the oil sensor and the other is the water temperature sensor. One has a flat end where the wire goes and the other has a end with a tap on it. I found a hole on the right side of the 350 SB where I believe one goes, but I don't know which one goes there and I can't find where the other one goes. Please help.

Thanks

Re: Help With Sensors

Sounds like they're both water temp sensors, most of the oil sensors I've seen have 1/8" or 1/4" pipe threads on them. Temp sensors usually screw into the heads and oil is usually at the rear of the intake or around the oil filter area.

Re: Help With Sensors

look on the other head, there should be a hole on that one too.
Does/did your truck have dummy lights, or guages on it when you took it apart?
