Answer: Yes you can use the gear shift light output for rad fan control. You would simply use the switched negative as the negative side of a normal 30amp relay and use the output of the relay to power your fan. The instructions that show you how to wire a shift light using a relay are identical to that required for using your rad fan. You would simply then need to configure the output to come on at say, 750rpm and on at 85 degrees and off at 80 degrees.
