1st - they are going to look awesome on that car.
2nd - what do you mean by light loom? the harness?
I don't have personal experience with it all yet, but I'm going to assume it's the same as e-codes.
At least, it looks that way. I know the "light fixtures" do come apart from the housings via 3 screw-looking things that come undone.
I'm sure someone who has more 1st hand experience with it will chime in.
