Hi Patrick, I would agree that using the fused connection on the "ignition
switched" side of the fuse block as the source would be a good idea. The
ignition switch is not fuse protected so by using that as a source you do
run a risk of "letting the smoke out" should a short to ground occur in
your fan system.
You may find that the electrical demands of your fan are more than the
fuses can handle as the system was not designed with heavy continuous loads
in mind.
To circumvent that issue you could use the unfused side of the "ignition
switched" section of the fuse block as the source and install an "in line"
fuse to protect the fan circuit.
I cannot overemphasize the importance of protecting the fan circuit with a
fuse, it very easy to damage a wiring harness and replacing one is a major
undertaking.
