Pretty straight forward... i setup a mark 8 system in my truck, so far works great. But temperature hasnt gotten over 75 here since install. I currently have it wired to speed 2, but my concern is that turning on the AC without the fan already running will kick it into speed 2 and draw waaay too much initially.
