Just a heads up for anyone wanting a real nice fan controller... I've been building my Torana for a while, and used a Spal controller to run the fans on it Spal Fan Controller and just got it all dialed in today. Works awesome

Has low and high temp limits for the fans along with an a/c input as well (which I used) so it kicks them up automatically when needed.

It can also use a factory sending unit if you want too, or add thier own. I am running mine off the stock sending unit..
