It comes complete with the 40 amp relay, wires, fuses, and 3/8" NPT brass thermostat. If you recognize just what to look for, it ll come to be 2nd nature. From the (second) A/C relay, connect the yellow and orange wires to the ground. If you have installed an aftermarket electric fan, that did not come with a thermostatic control, the PFC can be programmed to turn it ON and OFF at any desired preset temperature. Black wire. The fan will turn on when the A/C compressor activates. Electric Cooling Fans Schematics 4-cylinder cars 4-cylinder cars with added relay Factory V8 Factory V8 modified Hover over a wire to confirm the colour. Feels free to follow us! Resistance: Measured in Ohms (R or O), resistance specifies just how quickly electrons can move via a material. Use a female terminal on the other end and attach it to the switch terminal of the relay. Connect the Red wire to the sending unit wire of the original fan relay harness. Remove the negative terminal of the battery first so that there is no chance of sparks. Route the 16-guage wire up the fenderwell and through the firewall to just below the dash. I cut the wire in half running from the fan to the switch and hooked the wire from the fan to post#85 and the other side going to the switch to post#87 and then ran a new wire from post#30 to the alt but the fan runs all … Cooling Fan M.A.D.
