which do you want?

to control the fans or have it run as if it came with the electric fans installed?

this could be the reason you are running in to problems...

there are walk through posts on this forum on what you need, and need to do.

i dont recall anyone ever having "control" over the fans other than turning them on and off. this was purely for when going through deeper water.
Nelson just programs the tune so it turns on at certian temps, just like your current belt driven fan turns on at a certian temp.

If you are looking for more than that, i can see where this would cause problems. how would you control the fans? a simple dial knob like a dimmer switch? what purpose would this be for?
