So I'm trying to figure out how to rig in an Spal high CFM fan but I don't know how the fan control module functions and were I would interface the fan/extra relays and wiring with this module to keep everything happy.
The shop manual doesn't provide any information on the module.
Anyone smarter than me have any input? How is the duty cycle of the fan controlled? PWM? Some of the aftermarket fans available from Rock auto as direct swap in don't have a module and there is a 2 pin plug connected straight to the fan so can I just bypass the fan module without pissing the ecu off?
I know how to run switched 12V to a relay and into the fan.
