I'm trying to build a "control pack" for my Godzilla take out motor. Unfortunately Godzilla parts are still harder to come by but Coyote parts are not (Ford MAF pigtail for the Godzilla is like $100). I'm looking at the wiring pinouts for both of them and the Coyote shows a pin thats 12v to the MAF at location 3




The Godzilla MAF plug
Lists
Pin 1- MAF
Pin 2- VREF
Pin 3- MAF Return
Pin 4- IAT

There doesn't appear to be a 12v lead going to the Godzilla MAF. Can you use the Coyote MAF on a Godzilla PCM if you're feeding the Coyote MAF a 12V instead of the VREF? What issues would that cause since the Godzilla PCM is supposed to be sending out a VREF for the MAF and IAT?

Thanks

That maybe the way to go, but I was hoping for something fancy controlled by the PCM. Some how Ford has electric fans in their 7.3 Godzilla control pack.

I'm working on a godzilla swap and the godzilla body harness has only an FC-V fan wire on the PCM thats located on Pin #4 of the PCM plug. The godzilla originally had a clutch fan that it was able to control with the PCM. Is there any way to make the PCM control an electric fan? I'm wondering if I could just wire up a Ford Fusion soft start fan controller that uses a PWM ground signal to control the fan, but I'm not sure what FC-V wire is putting out? Power? Ground?

Also on the transmission harness there is a Fan Speed sensor wire would that need to be hooked up to something to keep the PCM happy?

Is there a way to have the PCM control a relay to just engage an electric fan?

Thanks
