generally very simple (and this applies to all cars with clutch fans basically)

you run a wire 16 or 18awg for the hot to the relay’s power in, you run same thing from relay’s power out to the fan’s hot and then the other fan wire to ground (pick a spot on the chassis)

run any old dinky wire 22awg or larger for the relay trigger power from your switched ignition source, and run the trigger ground to chassis OR to a thermostatic relay if you want it to cycle on/off by temperature

some fans will have a low speed and high speed (ie maxima), usually run by a seperate pair of wires so you could have both speeds controlled by temperature if you can manage to install both the probes into the radiator/waterneck whatever
