ML to GLE Conversion headlight question

I am looking to convert my 13 ml to gle 63 facelift. Everything looks very straightforward but the headlights.

My current headlights are bi xenon. I am assuming i need the new ILS headlights as well... BUT i am assuming the connectors will be different. Any ideas? Take apart old and new headlights and swap out the wiring and components? or is there an wiring harness adapter?

thanks. I was search around found that on w212 it is more popular for conversions they have pre-made adapters etc..

I found adapters to convert from holagen to led. https://www.kabeldaviko.de/product_i...-airmatic.html
and some person from china that does not speak english trying to sell me a harness for $800 but requires some sort of programming... Go figure.

my current bi-xenon headlights already have most of the same features as the new headlights, it shouldn't be as hard as going from halogen to LED.

As I said. You never come away from needing codings..And Stereo cameras in windshield if you dont have that.

Can any shop do the coding? Can you point me in the right direction.

I do not care of all features of the headlight work.

my car comes with the parking assist, blind spot checker, adaptive lighting package. Not sure if I have a windshield camera or not.

what wiring harness would I need?
What are my options for headlights?

sorry for all the questions. Trying to figure out what to do and if to do it.

Yes but you will need a new GLE hood/grill, front bumper cover, and headlight mounting brackets.

If you mean facelift headlights you need new GLE hood/grill, front bumper cover, Fenders,Converter cable for airmatic or non airmatic and alot of codings.

For LED non facelift you need Converter cable for airmatic or non airmatic and alot of codings.

If you cannot do what the other's suggested, I would suggest going with @AZN Optics Xenon's. They will do the job.
