which oem foglight switch? ek or eg? if i understand what i think you are trying to do, (use the oem foglight switch with your afermarket fogs) i don't think you could use the ek switch; it is not a on/off posistion switch, it just turns the relay on and off.
...i could be wrong though... i have the jdm ek fogs, and the switch doesn't 'click' in and out (like the hazard button) when you press it you can hear a little 'click' from the relay, like when you turn on the rear window defroster... (and the switch is still in the same posistion doesn't stay down)
