Anyone care to walk me through the steps to wire this up? Currently the fan on my car runs continuously, I'd like for it to function correctly. Its installed on a '92 Mazda MX-3 with a 88-89 MX-6 GT F2T swap.

Check your ecu temp readout to confirm it's correct, then the fan trigger setting in the menu. in my ~5 yr old unit, the PNP setting had a 70 degree adder to the target temp of 210 or whatever. Stick a voltmeter on the output pin & confirm it's changing state at the trigger setting.
If it changing state, go for standard electrical stuff like a stuck relay.

He's asking how to wire it up. It's not part of the engine harness in that car. ECU currently has no idea that the car even has a cooling fan.
It's probably running constantly because the entire circuit from the 88-89 MX6 isn't there, and those cars have a fail-safe where if something breaks or isn't present, the fan just runs full time.
Does this help?
