Thanks.... I try. I'm still young enough to know everything but old enough to be wrong about all of it... And still young enough to never admit to that last part when it comes up.
The wiring doesn't have to be a nightmare; Do some research and buy the right gauge wire for the job, inline fuses for each fan, additional relays (if needed), and a thermostatic switch. There may be a more complete writeup on here about how to get it done (properly)... I know there was one advocating the use of the A/C's high temp switches which I would ignore but there may be more information posted in that thread which is useful.
