[urq] UrQ After run Radiator Fan

[Andrew Finney]

Justin, the reason the radiator thermoswitches have 3
pins is that Audi relocated the overheat high temp
switch down from the line between the bottom of the
coolant recovery tank to the radiator(where it is on
my '83 UrQ) to the bottom of the radiator in one
thermoswitch(where it is on my '84). That third pin
has nothing to do with afterrun. I believe the
afterrun get's its signal from a sensor mounted like
our injector cooling fan thermoswitch on the cam
cover. The reason I asked the group is that I wondered
if someone had done an easy swap of a relay or two
with a jumper wire or some such thing from the
injector cooling fan thermoswitch. Thanks.
