Does your eBay headlight have connector for ALC control unit?

EuroCarFan

I assume ACL is short for the adaptive feature. Yes that eBay unit does.

Let me give you a list of part number for ballast

my530i

63 21 6 937 223 (new part number)
63 12 6 907 488 (old part number)

EuroCarFan

So what do you mean by new vs old? Were there two different ballasts?

my530i

The old part cannot be used for new car, but the new part can be used for old car (up to 01/2005)

EuroCarFan

I think you lost me. haha

So get the new part and it'll fit on the eurospec headlights? Would you happen to have a picture of the new part?

my530i

The part list does not have real pic. Check if your ballast on your car fit the one you bought on eBay.

EuroCarFan

The ballast on my car, which looks like the picture you posted earlier, doesn't fit the headlights I bought on eBay. So I'm assuming one of those part numbers you provided will fit but which one? Wish I could see pics so I can tell if they're the right part or not.

Went for the clear corners huh ECF? Good luck in getting them to work. Hope you get them done soon. I'll be in SJ this Sat. Let me know when you get them done. I wanna see!
