OK, I'm stumped on this one! The PET images calls #33 a temperature switch, and I have it on my engine. I can't find the wires that go to that switch on the 1980 ROW or USA current flow diagrams. Anybody know what that switch does?

i had that on mine too, but was not hooked to anything..

On a CIS car it'll go to a solenoid that decreases control pressure and consequently provides a richer mixture on cold starts.

Glen, is this related to the WUR? Or a different solenoid? If only used for CIS, then I don't need it anymore - at least electrically.

Ducman82

You won't need it.

GlenL

Yes, it controls pressure to the WUR.

Thanks Glen. That just made my life easier!
