JLS500

Ok so I got into a fender bender and the left headlight is broken so I thought I could upgrade my headlights to the newer style lights but there’s a extra wire for the auto leveling I believe.
the word out there there’s a adapter kit for the lights but I have been searching for almost 2weeks and the car will be finished next week.
I’ve looked on eBay and the 03 /06 light are Available but I can’t find the adapter kit.
I found a company autowerks direct but there out of business.
can anyone help I really don’t want to pay 300 for a old style light when I can pick up a nice pair of upgraded light for 200
