You got 3 options:
Get a relay and use a switched power source to turn the relay on/off.
Get a relay and make a toggle switch to turn the relay on/off.
Get a fan controller with thermo switch on it.

Horrible idea. So when it burns up, you also burn up the fuel pump circuit.

The fan shouldn't be staying on if the power source isn't constant. Use a relay, trigger it from the black/red ignition lead from the key switch.

i got 30a inline fuse,30a relay on both my fans been running this for years i think i took all the precaution to prevent that..oh i forgot i also electrical taped the hot wire as well as rapped the wire with the thiniest vac. tubing i can find so it dosent short out,(fan on the switch)as a precaution i ran the ground wire through my firewall instead of the hotwire so if my efan system wanted to short out LOL my fans would be on when my cars is off

this has been working out fine..like i said fixes the problem of fan running constantly

INTERNET IS ALL HERE SAY..what are we to do..believe what others say...???
