I'm thinking about taking my controller to the next step and offering an epoxy sealed control unit with weatherproof harness connectors to allow you to basically plug n play this to ANY fan or dual fan setup and have the ability to run it at 1, 2 or 3 speed fan operation. It will consist of a main IGN control, an AC override, 2 temp switches and an externally mounted resistor board that simply needs to be mounted where there is some airflow-it can even be mounted onto the fan shroud.
The epoxy is a nitrogen rich type so its basically won't ever be able to melt or catch on fire. The relay control unit has diode and resistor equipped relays (not Chinese crap either!) all with a minimum or 250,000 switching cycles at full load-so in essence, they'll last practically forever. Right now I'm looking at a cost of about $175 per unit and I'll be offering a 5 year warranty on the unit-I'm that convinced of its durability! The supplied temp switches will allow an operating temperature of 190-195 assuming you have an adequate electric fan. Thoughts? Let me know what you think-I'm in the final stages of production for this unit so input would be great!

Again, I'd like to stress that this control unit can be used with or without an ECM. Thanks!

 

Hmm, I like this... Nice Quiet Operation on Low, Medium as a Default and High to bring Down the Operating Temp. I Like!
