That's where your dash override switch goes, if you want one.  Otherwise,
just tie it off and leave it alone.

Easy with the DeRale kit.  Connect the yellow wire to "always hot" (this
allows the fan to run anytime the sensor is above the set point); but power
the override switch from switched power (so it will only override when the
ignition is on).  Only caveat is to be sure the fan can cool the sensor, so
the fan doesn't run continuously on a hot day.

With a little more imagination, you could probably figure out how to put a
timer on the yellow wire, to limit the fan to running say 10 minutes after
the key is off.  But that seems way over the top to me, especially for a
lowly TRactor motor.

Good advice, but far too late ... <G>
