Never seen it before
Hi Guys
I realize this will bar my membership in the know it all club but I'm at work away from any reference material and my truck is in NorCal. I remembered that as I was crawling around my truck the other day I came across this part hanging on the radiator support next to the A/C stuff and I have to admit, I can't remember ever seeing one before.
What is it?
I'll include the pic.

Its not a socket. There is a lense there kind of like a sensor. I'll add a couple more pics. They are fuzzy cause I was trying to get close.

I would but I can't read it.
I have a feeling he'll know without needing a number.

But I guess not.
It just seems that a mechanical switch would be cheaper and easier for them.
I'm curious about the mercury question as mercury needs movement for the switch to work so why is it mounted on the radiator support.
I love finding out the history on these things.
