First thing is you need the part number of that wiring harness.
If you can't get a specific part number because it can only be had when buying full overhead light unit, then get part number for that.
Head to ebay or to your nearest junkyard.
Use realoem website or ask the dealer for part number.
Edit: hybrid90, I just saw you had 227 posts... pretty sure you know about all I've said above
