Hey guys! The 331 is running and leak free. What an engine!

I've been tapping the electric fan directly to the battery while we tune the car, but now I want to wire it correctly. I have a thermostat control and an electric fan with a positive and round cable. It is a 2500 cfm fan. Where should I tap the positive wire on the fan to?

Thanks!

What type of fan switch module do you have? Is it a probe or is it a sensor that is mounted into a water jacket? It shouldn't really matter at all, but I used the radiator mounted probe.

I wired mine from the fan to the relay/switch and then to a 20amp circuit breaker, and then to the battery side of the solenoid and of course a ground wire.

Here is the circuit breaker I used.

Here are the wiring instructions for my switch that should be pretty close to yours.

Glad you got your 331 running! I know your build is similar to mine. Pretty crazy power huh! So much for the "experts"
