It's been a very long time since I installed a trans temp gauge. Does anybody know, on the back of the gauge the are three male connectors (GRD, S, and I), where do the S and the I hook up? GRD is obvious but I don't remember what goes where with the other two. Anybody know? Thanks.

 

Just a guess...S could be the sender wire, and I could be instruments lights.

 

Yep, that's it. S- signal or sender, I- switched power and GRD is ground of course.

 

Yeah, I figured it out after about 2 mins of really thinking. Thanks for the help.
