Yeah, I guess the easiest way would be to run one wire and splice it onto the green wire on the #8 relay then run this wire to one terminal of the switch then ground the other terminal of the switch. . That a way when you have this switch in the on position your fans will come on as soon as you turn the ignition key on, and when its in the off position the fans will come on when they always have around 195 to 210 (this is when mine turned on). Or you can run a switch for the low speed (#8 Relay, Ground Dark Green Wire) and a switch for the high speed (#7 Relay, Ground Dark Blue wire). This is what I plan to do. I am no in any hurry to do this because I like my fans on all the time to keep things cool all the time.
