Does anyone know if you still need a 75 amp relay with the delta fan control unit, model fx35. How did evryone wire it as well, did you use the hi speed or low speed, I will be using the a/c with mine as well. Thanks

Everything you need with for the install comes with the kit.(Except for the fan). Wire it as the instructions say. I used the high speed wire. The fan comes on when it needs to and ramps up the speed as temp. rises. Its never actually spun the fan at full speed because its never needed it.

Thanks for the info, did you wire it to always hot so the fan will cool for a few minutes after the vehicle shuts down, or to a wire with the ignition switch.

Man you ask a lot of questions LOL. This is personal preference, sometimes a car can heat up even more for a few minutes after shutting it down so you may want to wire it so its always hot, me however, I was uncomfortable doing this because if that temp sensor ever fouls up and runs my fan until my battery is dead...well I am stuck! I tore my AC out of my car so I didn't wire that up and yes everything you need comes with the controller, and I think the model is FK35, not FX35.

It's the only way to learn, heh.

i wouldnt wire it hot because it wont cool the car after the motor is shut off so why drain the battery. when the motor is off, the water pump is no longer moving coolant so if you run the fan when the car is off, all your doing is cooling your radiator
