i was wondering how i can electircally hook up dual fans of a late model monte carlo onto my 86 c10.  i want to use a thermo switch. now, do these work by groundin the circuit? if so all i need to do is run ground wires from the fans to the switch? any help i would greatly appreciate  

man i got a 79 monte carlo with a single electric fan and what i did was ground the fan to the frame of the car and i found a fuse in my fuse box that works by the ignition switch and ran a wire to it so when i switch my car on the fan comes on .ive been riding like that fro tha past 3 years.Thats the best i can tell you bro!!  

hey howareya?, i've got a older montecarlo that i put dual elec. fans in. i ordered a relay and thermo kit from painless wiring,it's been cooling her off for years now, and let me tell you it gets real hot in vegas,call painless and be cool......
