Re: electric fan wiring
Blitzer454 is dead on with his advice. An E-fan arrangement should ALWAYS use a relay, due to its high amp draw. I'd even recommend a controller to operate it. There are one and two speed controllers that you can purchase, and the good ones come with relays and wiring, along with wiring diagrams to assist in wiring it properly.
Flex-O-Lite sells a good one. They are pricey (in the $100.00 plus range), which might be why folks don't use them. I ask myself, why would I skimp on something important like a E-fan controller on such a classic car?
Never argue with an idiot; they'll only drag you down to their level, then beat you with experience.
