Hey guys i'm going around in circles.. I just purchased a 2018 GTI and want to fit the 5G2052200B tail lights . Ive been offered a set for $580 but what else do i need?

I cant work out if i need a harness and if my OBDeleven can program it.

Alot of info on fitting to a MK7 but not a 7.5 GTI.. Can any one steer me in the right direction?

Cheers, Mark
