I thought about getting one of those and calling it a day.Save the time and money and just buy a Black Magic... they work great and are easy to install.
Easiest way to do it.
E-fan $30-50
75A relay $20
toggle switch $5
misc wire and connectors $10-15
That will get you started. Down the line, if you want to add a controller, you can buy one and wire it in. But not necessary. I ran my fan off a toggle for 9 years before swapping to a controller. I actually got a little creative and wired in a green LED on the fan input wire so anytime the fan was engaged, it would light the little green LED next to my autometer water temp gauge.
I have a Derale controller that i got from summit, its worked well so far, the relay did pop once on it, and that sucked, so from now on i am keeping spare relays in the car at all times. Would be a good idea with any controller
Is that about what a dual fan contour setup goes for at a pull a part? and where did you get the relay? Ill probably set it up on a controller, i know DC's are the bomb but are the ones at autozone any good in a pinch?
