On another note, I’m getting ready to start running some wire. My brother is the brains behind this but we were discussing routing options. This is the $60 relay I bought and the only 2 red wires from the main bulkhead in the firewall that I’m going to use. I have 2 60 amp fuses. My brother ordered the blue plug from GM which he somehow knew would plug right into this relay. 1 wire to the ignition and one to the fan control. I think I have a decent idea of where to mount the relay back up near the headlight/core support area.
This is the fan controller. The big plug had 5 wires in originally but we removed 2 of them since they weren’t going to be used. The yellow and black wires tie into the temp sensor in the cylinder head.
The controller has 2 screws holding the back cover on. Open it up and there’s 4 temperature settings so you can choose where the fans come on. It’ll probably be mounted inside under the dash some place. I have a spool of 10 gauge wire which I think would work ok but my brother suggested I buy some 8 gauge and run a wire from the alternator to the battery, then another one from the battery across to the power in stud on the relay I pictured above.
