Default EFK Question...

Doing my timing belt at the end of august and was contemplating tossing an EFK from SPP while the front end was apart.

1.) Where do you electrically tap to power the fan?
2.) Does it run constantly just as the mechanical one does? If not, what signal switches the fan on?

thanks

Default You tap power from the Aux fan. The EFK only comes on with the aux fan

which is whenever the AC is on or if the coolant is over a certain temp - like 210 degrees or summin. IMHO - you need an adjustable fan switch or a 190 degree one like what Neuspeed sells.

BTW - there are pics of the SPP fan in my pic poster.
