Not Ranked
Just something that I added to my Cobra for extra peace of mind. I never had the ECU unit or anything to worry about and my fan thermostat was adjustable over a fairly wide range. But just for extra peace of mind, I took a lead off the thermostat and ran it through a toggle switch on the dash and another relay so that if the fan relay or fuse for the thermostat lead blew, I could run the fan manually with the toggle switch until I got home and could fix the problem.
