[urq] Radiator cooling fan

[Thatcher Hubbard]

As long as it's functioning correctly, you can let the existing cooling fan
circuit handle it, which is about the only part of the 034EFI swap that was
easy. Of course, mine was a total mess, and I still don't have the high
speed circuit working, which is bad, because when it tries to trigger the
high speed and it doesn't come on, that doesn't mean that the medium circuit
continues to function.
I've decided that the best setup is probably a SPAL fan (quieter, better air
volume) and an independently wired SPAL controller.  Not even that
expensive.
