i am running the 4th gen fans on my car ... i already have a temp sender that sends a ground to the ecm to turn on the fans at temperature. what i want is to be able to manually turn on the fans at the track with a switch in the car. i bought a painless switch with a lighted indicator. there are 3 pins on the back. ... what i want to do is to tap into the wire coming off the temp sender in the block to the switch.. when i switch it on, it must ground that wire ..
how do i do that while getting the indicator light to function when the switch is on and not sending power to the temp sender??
probably a simple answer to this, but cannot figure it out.
