hi jkseries.
have a look at your front door posts look for the curtesy light switch it has a x head screw in it to hold it to door frame, remove this and the switch will come out.
be careful removing it as the cable is a bit brittle look at the switch ,you will see the electrical contacts .Clean these and also where the switch contacts the door frame,this may get you going .
If not remove the off side passenger door switch its the same as drivers door .
splice a cable into it and run it to the front curtesy light switch and away you go .
it worked for me.
