attached is a corrected fog light wiring schematic from the Ford installation instructions. Ford originally had the 2nd relay not grounded on pin 86, but to 12v instead. It also was not specific on the which pins the wires attached to on the relays. I remove unused pins from the relays in the schematic, Pin 87A from fog light relay and pin 87 from the F L cut out relay.
With this set up the fogs work correctly, only on when the low beams are activated.
