Default NB AC compressor question for someone smarter than me

Currently doing a engine swap in my NB, dropped the subframe out of the engine yesterday. I decided to leave the AC Compressor in the engine bay so that I didnt have to purge the system. One issue however, I managed to rip a wire out of the compressor in the process. There is a single wire that runs to the compressor, attaches to what looks like a thermal sensor of some type and then runs to the clutch assembly. On the JDM motor I got months ago for my dads NA it also came with a Compressor but its different than mine. Its smaller and also doesnt have the same thermal switch at all. I was just going to bypass this thermal switch and run the signal wire directly to the Compressor, I dont see what the point of this thermal sensor is, but maybe someone smarter than me can shed some light on it for me? Thanks guys and gals. Attaching pics... one is the compressor in the car and the other is the misterious smaller compressor thats JDM and ****.

( dont mind the dirty compressor it will be cleaned before the shiny new engine goes in ).

I believe it is indeed a thermal switch. I believe it contains a bimetallic strip that turns the thing off if it gets too hot. Sometimes the switch goes bad and won't let the compressor run, and folks jumper the connector so that the switch is bypassed.

Awesome thats what I figured, just jumper the wire and run it directly. You Sir get a cat for your good deed, looks like you and I both are in the negative LOL. Thanks again brother
