Thermastat gauge wiring Question

[Southern Rebel]

When I bought my blazer the thermostat gauge did not work, when I took the cluster out, it was not even hooked up and the hole in the water housing was blocked off. I have bought a switch that screws into the water housing, but do not know what kind of wiring it takes. Does anybody know what kind of connectors it takes to go into the thermostat gauge? I can pretty much figure out the connect on the switch. If at all possible, pictures would be a great help. Thanks
