thats how i had my truck setup before i did the swap. the elec fans were controlled by a thermo probe that stuck thru the fins of the radiator and a switch on the dash so i could turn them on whenever i wanted.

the reason i say use a relay is so you arent having to run the power needed for the fans thru a switch. they use alot of amps and its not good to have that much power running thru your firewall and dash. its pretty easy to setup on relays and much safer.
