For those re-pinning, this is how the Euro inner tail connectors should look when done. The black wire in pin 4 is the new wire added from the BDC. Black on both sides. The pin 1 wires black/yellow and black/white are rear fog wires. Most US cars won't have these. So all wiring coloring is BMW spec except the black wires added from the BDC.
Hope this helps. The pic in hand is left, connected is right.
