[W126 Coupe] Headlight installation help

[Lou Carrillo]

When I replaced my US (gray market 1984 500SEC euro) with Euro headlights, I also had the 6 pin plugs but as I recall I had to take the plug apart and move the contacts/ wires around a bit to match the new headlights, I used a multi-meter to sort it out. I also left the US spec two filament running lights/turn signal bulbs in the corners for legality,  but I put a 10 ohm resistor in line with the running lights because I thought they were too bright.
