Isis system and radiator fan controller?
I haven't bought the Isis system yet but plan to. I'm currently ordering a autorad and need to know if I should order the fan controller? Will the Isis system make the $100 harness not required?

you will still need a controller to have the fan temp-based. the ISIS kit supplies a signal wire to turn it on/off (tan wire from power cell #1).

Does the Isis eliminate the need for the relays?

No. ISIS PowerCells support up to 25A. Most fans need 30A during their initial kick-on. The ISIS-recommended method is to use the fan wire as the positive part of a fan relay.Does the Isis eliminate the need for the relays?
