The E-fan system runs off the previously-unused Fuse K, and involves 3 relays: low speed (controlled by a dash switch & a low-temp switch), high speed (controlled by a high-temp switch), and A/C which forces the high-speed relay on when the compressor clutch is energized. The wire for high is AWG8; low is AWG10. I left some extra wire under the relays for future changes to the fans. The 4th relay position is available for future use.

Eventually, the relay burned out & I switched back to the (more-reliable & fuel-efficient) clutched fan.
