    The preexisting Electric Fans output in Basic I/O - System Parameters (System ICF), don't utilize the custom Inputs/Outputs ICF. And vice-versa, a custom created Electric Fan Output in the Inputs/Outputs ICF, doesn't involve the preexisting Electric Fans output in Basic I/O - System Parameters (System ICF). Please read post #1 of this forum thread again. Of course, both types will require Pin Mapping.

    OK, read through this thread and I still have questions. I plan to go the Fusion fan/controller route. Do I need the 75 amp protected relay? A diode? A relay to run the PWM controller? Or does the PWM on the fusion fan have a built-in relay that's only wired to the HP?

    When using the Fusion fan & controller, the setup is exactly the same as the Corvette. No need for any relays. The controller has 5 wires. Two go to the motor, two go to the battery, one small wire gets connected to a PWM- Output on your HP. On the battery connection, on the positive side, wire a 40 circuit breakers. Done. Andrew
