I used some parts that I had laying around, but I think you could buy a pair of these (#1), put them on each end of a wire and push them into the empty spot on your connectors. You would need to measure which ones you needed.
Various parts, wiring harness repair BMW X5 E70, X5 4.8i (N62N)
Look at the other holes that have a wire in them, you want to duplicate that with the correct size part #1.
You could proabbly also buy something at Radio Shack and do the same thing.
Hope this helps.
