I have dual electric fans on my radiator should I just wire both wires to the factory harness or should I wire each one individually? Is there a difference?
You're gonna need individual wiring and relays for each fan. I wouldn't even use the factory wiring at all.
Lots of companies sell dual fan relay/wiring kits that make it easy. You'll need to decide what you want to trigger the fans with. Most use a temp switch and it is included in a lot of the dual fan relay/wiring kits. I usually also tie in the AC compressor output and add a manual toggle switch for emergency.
