Im carbed now and would like to wire the fan that is controlled by the ecm to a jegs cooling fan relay kit. Right now its on a toggle switch. My question is it has 4 wires a pink wire for 12 volt power then another pink wire to go to the positive side on the fan a yellow for the thermal switch and a gray to go to a toggle switch. My question is will i still need a 12 volt power wire to the toggle switch or just the gray wire to one blade on the toggle switch. My other question is should i use a switched or full time 12 volt power source to the new relay?
