is there a way of testing the auxilary fan? there are 3 wires in the harness, 1 brown (ground) 1 blue ( im thinking + power) and a thin wire black(goes to the ecm) , by jumping power directly to the fan motor it should go on ? right? or does the thin wire need to be jumped too? does anyone have a method of testing this fan?
thanks
ps nice write up jim on the auxilary fan removal.
