Rewiring my EFI Magnum - 1970 Dart Swinger

I like it with the fan switch in lighter spot. Just a thought, keep the fan on all the time and when you turn on OD, the switch can also turn fan off since when in OD you're at speed with good air flow and not needed. make the fan switch to turn off fan if wanted then when you have AC added you won't have to change the wiring to have fan on at low speed to move air across condenser.
