Just an option.
It also includes the ability to switch the parallel mode on/off when you're not at the track.

 

@ dynodragon. Can you post the alternate wiring some how so we don't have to join that forum?

 

Sorry - I thought you could see it without joining.
My concept here was to use the existing wiring and fuses and just add a relay to trigger the AC fan. The new relay is wired to the AC fan the same as the stock one, except the trigger is from the cooling fan as opposed to the ECU/AC switch. I also added a switch so I can run completely stock on the street.
