Hello,
I have googled and can't seem to find out how to wire up this Hayden 3654 (dual fan / dual speed) controller to the contour dual fan. I am trying to have both high and low speed.
I have the fans, the low speed dropping resistor pack and the Hayden controller. I can figure out high speed but not sure how to wire in for low speed using the resistor pack? Any help is appreciated.

resister is going to go in series to reduce voltage so you can have slow spinning

If this is two fans

Low is one fan
High is two fans

No?

I think I got it figured out. I am going to take the low speed tap from the controller into the dropping resistor then out to each fan, the high speed taps from controller will go direct to each fan. Let me know if that sounds correct.

I rethought about it

I would verify if these fan motors can be safely dropped by voltage

the dropping resistor is part of the ford contour wiring schematic and a factory part. I am going to give it a shot and see.

I have Contour fans and a Dakota Digital controler. I'm using the factory harness on the fans with the resistors (I installed a new one from ROck Auto.) I have my fan controller set to run two seperate fans. The fans come on at low speed as fan one, then they come on high as fan two. I have a 70 amp relay on the low side, and a 40 on the high side. I used the 70 amp on the low side because while being lower draw at low speed, that is where the in rush load is to start the fans. Been running this way for a year and a half, and works great.
