Radiator Fan Relays
 

Hey Guys,

Im trying to install a switch so I can activate the radiator fans early if I come to traffic or slow driving. Ive had a read of The Big Cooling thread and read the fan mod for it (http://rx7.voodoobox.net/howto/fanswitch/fanswitch.html) but my question is, should the two small wires in each relay have power doing through it when the reds are on? I was told one should and one shouldn't and the one that shouldn't is the one that I run to a switch for the ground.

Has anyone done this mod? or anything the same as this?

Thanks

Hayden
