I was able to get a 2000 a4 for parts and I wanted to swap the headliner out into my prefacelift 1999 since my headliner is all brown and gross. I was able to get the headliner out of the 2000 a4 when I was comparing the newer style sunroof controls and lights, the connectors are different compared to the older style. Has anyone wired this up yet or even done this retrofit?
