I'm in Adana Turkey right now and for the last year (probably in the high 80s-100ish for 6 mo). Offroading? Yes, but not as much as I'd like. Not sure how that factors in. If the electric pushes the same or more CFMs as the crank fan, it'll perform better because it puts less load on the engine and can run at full RPMs regardless of engine speed...crucial when off-roading. If not, it'll perform worse, so make sure you get one with the right CFMs.

 

So I'm wrapping up the wiring and trying to figure the best way to have my manual cab switch relay and the factory relay wiring control both fans either when the manual switch or when the AC controls and fans.

As of right now I have both circuits controlling the dual fans. Either the manual switch in the cab or factory AC fan control. Both wired to the fans. It woks great for the moment. But should I be worried about both circuits tie together With nothing to keep Whe electric flow from crossing?
