RE: Reg MKII's and cooling fans.

["George Tylinski" <tylinskig@asme.org>]

And for the truly bizarre (talking Wayland show car here), use the
existing car lights as load+indicator: 2 brake, 2 reverse, 8 signals,
one dome (or?) = 13 They might not all handle 2 amps in stock form, but
may need an upgrade (or put an appropiate resistor in series). Not
really more wiring, but less clean. It would sure dilute the thermal
load. No need to clutter the dashboard either. Uh, I see further down
that you're not using external loads, so this probably wouldn't be a
solution in that case...
