Wiring relays for fuel pump and tranny cooler fan

[Heiner921]

Was wondering if anyone uses relays to run fuel pumps and tranny cooler fans? or are you just running battery positive to toggle switch to fan? if using a relay, how are you wiring it?

I don't run a Tran fan just a fuel pump but I just run wires and twist them together. No switches or relays.

For fans I use a gator clip, the kind your average mid size battery charger has on it, with a fuse. No switch to fail and a lot easier then twisting wires.

I've ran trans cooler with fan and electric engine cooling fans for years. I never ran any relays, just make and female insulated terminals so the connection is insulated and won't come apart during the derby.

just plug then togehter when pulling on track and unplug them after you are out

My mini fans run 15 amp fuses.

No switches, fuses, or relays on any of my cars.I just twist wires together, all my wires are labled so they don't get mixed up
