Does your truck have A/C?

Maybe a few more pics of surrounding area?

Or a pic of the bracket/area it came from. Was it just laying there next to the carb?

Might be A/C compressor switch. Being on the DS of carb is about where the compressor would be if you had an A/C system. Just a guess!

That air temperature switch inserts through the side of the air cleaner housing and is retained by a horseshoe spring clip.  It is part of the AIR emissions package (smog pump) control circuit.  The switch contacts should close above ~60° F.

That makes perfect sense, I see the clip groove now.

D'oh!

Thanks so much for helping me. I will try to see if I can find the spot it goes in.
