The easiest way I have found to wire a fan is run a relay on the positive wire controlled with the Ign. circuit then add a thermostat to control the fan ground.The thermostat can be bought from any Flex-a-lite dealer. I got mine fromSummit Pn# FLX-31147 Price 24.99. Its adjustable from 180-240 degrees to switch the fan on with provisions for a override switch.
