'86 T-type coolant temp sensor & connector

[ttypetex]

Trying to source either or both. All I can find on the net is a dual pin sensor set up. Mine is single pin, and connector secure tang is broken.

I assume everybody's is a single pin? Anyone know where to get it?

the two pin with the oval connector is the SU109 temp sensor, I think you are looking for the "temp switch", pt. #TU64 at AZ, Advance, etc.

Thanks. That is exactly it. Wonder what this temp switch controls?

Is the temp switch used just to light up the dash idiot light?

What is the SU109 temp sensor? Does that provide a signal to the ECM to help determine fueling mixture, maybe?
