    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

    I have everything wired as described. Dominator setup and Ron Davis radiator with his relay setup for Holley EFI. It works as should when starting/idling & initial driving, but after a bit of driving the fans turn off and car will start to rise in temp. If I shut the car off and restart, the fans immediately come back on as they should've been. I'm keeping constant +12V power to the relays when they should be turned on, but aren't. I selected "ground" for my Outputs. Could this be something with selection for +12V? I'm trying to determine if it's possible or there's some issue with relay to the fans. I only have a minute to test/check before having to shut the car back off, and fans will cycle back on when I turn power back on. It happens every time after I make some runs to datalog. Using B10 & B3 Outputs, one for each electric fan.

    This entire thread has been extremely useful and convinced me to go with a fan controller. I understand the wiring for the C-6 controller. I currently run the Holley Terminator EFI. I have my fans triggered with the negative wire from the CTS to a relay to provide the 12 Volts to the fans as per the instructions. When I convert to the C-6 controller, I'd like to use the 12 volt from the relay, basically the 12 volt from the relay would now go to the C-6 controller. I think this is the easiest way for me to power the controller. My question is in order to maintain constant power to the controller what should the Fan off/on settings be? (Basic I/O, Electric Fans section). On at a low temp, say 100°F and off a very high temp? I just want to provide power to the controller with what I already have in place. If this is not a good way, then I'm stumped at where the CTS trigger wire goes. Currently my fan is set to come on 185°F, off 175°F. I know that's way too narrow a window to keep power to the controller. I also understand all the other software requirements for the ECU to the controller that needs to be done. Just want to use the 12 volt source with what I have in place to provide power to the controller. Hope this makes sense.
    You don't want to do it that way, because it over complicates things and it wastes an Output. The CTS wire never goes anywhere except going to the ECU.

    The power connections to the C6 controller should go directly to the battery with a 40 amp circuit breaker in the positive lead. The Basic I/O settings for the fan (System ICF) will be disabled and an output will be created in the Inputs/Outputs ICF. The small wire going to the controller needs to go to an Output that is capable of being configured as a ground side (and PWM−). Andrew

    Would the Fusion/C6 controller box work for a fuel pump?

    No, it will not. Andrew

    Does anyone have current information on where connectors for the PWM fan controllers are available? I found some threads on other sites with part numbers, but they're all now obsolete. Worst case, I'll just pot the connector and make a pigtail to something like a Detusch DTP.
