Thanks for your help!

Tough to say without more info like part number and such. It appears to be non electronic. I would ground the body and run a hot lead to one post then measure voltage with a meter at the other post. Got a 50/50 chance of it being connected right the first time. If you don't get correct voltage then swap connections. Once you get it figured out be sure to mark it somehow.

You can also use a "light" voltage tester, light will be bright at 12v and dim at 6.

 

thats a bimetalic stip unit . need to know what part number or what its original vehicle it came out of as its a push in cluster one .

if thats a R307 unit power in is the spade by the upright to the left in the picture

 

Look real close as sometimes the stamp is light, but often there is a + on the power side.

 

if that's a Ford instrument voltage regulator, if you have a wiring diagram, figure it out. red is voltage.

 

Think I got it, thank y'all!
