1G A/C fan wiring

Justyn · Jul 16, 2026

Hey everyone, I’m trying to wire up my slim fan replacing the stock ac fan. I know my slim fan is a 1 speed fan and the stock ac fan is a 2 speed. How would I wire this up so it can be used like factory. Do I need to remove the resistor that is on the stock ac fan?

Thanks for the quick reply. Can I use the factory harness and factory relays and use the blue and black wires from the slim fan to the factory harness

You need to check how many amps it pulls throughout its operation to judge if the wiring needs to be replaced or not. Near close to the factory fan draw should be fine. Mishimoto?
