this is the aftermarket controler a member built so you don't need to worry which one you get. but the typical factory one can be wired direct.
I added a failsafe temp controler to bypass the controler should it fail, but had to add diaodes to the circuit or the backfeeding caused the fans to tick and drain the battery.
feets would have to repost his pics of both types of fans if the old links don't work.
