OP, I think your first issue might be that your sig says you drive an e92, but the MTEC box says e90 and e91. The sedan and coupe angel eye bulbs are different, no? However if your housing is melted that probably doesn't matter either way.
Sucks you had to return without getting them installed. I was looking forward to pics too.
