RamChargers Dual fan question

[Twil]

I have been using the RamChargers Turbo Regal Dual fan setup for one season. It really work great!! My question is:

How do I get the fans on with a toggle switch?

I had a toggle switch to ground at the green/yel wire located at the fan relay on the drv side fender. This work great untl I added this new dual fan setup. Now when I flip the toggle, nothing happens.

Also, these fans came with a special wire harness adapter. I'm almost sure this is the source of my dilemma.

Thanks,
Brandon

Well, because that wire your switch is conected to (grn/yel) is the trigger for the high speed fan relay.
These fans are wired to run off of the low speed fan relay (no they don't really run in low speed). They use that relay because it's the one controlled by the engine temperature sensor.

The high speed relay is triggered by the high temp coolant switch, or A/C.

You need to hook your toggle switch into the dark green wire on the low speed relay.

That should do it.
