My brother suggested a wiring solution, and I'll admit being sub-par in wiring. I can read a diagram, but that's about it.
Anyway, low amp in-line fuse between compressor coil wire to relay, use relay as switch, high amp in-line fuse from battery to relay, wire from relay to fan, ground fan. Good enough? Sounds solid to me, the fan comes on when I want it to, which when the a/c compressor is engaged.

Seems like you're good to go.
Low side is battery-switch-fuse-compressor-relay-ground
High side is battery-fuse-relay-ground
The fan will turn on every time the compressor kicks on. Your basic 40 amp Bosch relay works perfect for this, unless the fan is too big. You can get standard-style 50, 60, 75amp relays as well.
