OK me too, to some degree.
Can you ring out the fog light switch and determine if it has wiring to adapt to another relay, say one power wire in and one out.
Then you can either find the OEM relay position and wire the switch and the relay according ly or buy an extra automotive relay and wire it to the OEM switch.
it works out easily, fuse panel to switch to relay, then battery to fuse to relay to lights.
think it over, to me having Ford do it will work but you will always be going bak to them.
IMHO… just drop the wiring from the OEM Sw and wire up a new rely and circuit.
