Radiator Thermal Switch Plug

What are the voltages on the Radiator Thermal switch plug on a 1990 CQ?

Also, does anyone have a wiring diagram for it?

Wouldn't it just be 12v? I'm pretty sure it's just a thermal switch that closes as it gets to a certain temp.
yeah, that's what i was thinking, but i don't have 12v which is why i wanted a wiring chart. not sure where the wires come from to that switch.

Pin 3 gets 12v and then pins 1 and 2 are grounds.
