Ok since I hit a guard rail and shatter one headlight bezel, I decided to just put euro back on. Got a good deal on here. I am wondering if there is a different technique for switch a euro from us spec back to euro? I have the 6 pin connectors left but 2 of the pins were removed, I ordered a pair off of the bay for 12$. But thinking about it now I could have went to the JY and got a couple pins but then the local JY didn't have any w123's there.

About the missing pins, is there a white/gray wire with a red stripe that is pulled out of the main harness going to the front turn signals? That wire is for the city lights and would have to be put back in the 6 pin connector. There are only 5 pins going into the connector, the 6th hole in the connector is left blank. The other 4 plugs will need to be rearranged for the euro headlights. If your car has the vacuum adjustable headlights the purple vacuum line with yellow stripe will need to be plugged into the headlight. If you have any more questions just ask. I'm glad to help a fellow euro W123 owner:)

Thanks, I just looked at the manual too and it states the color combo for the pin lay out. Left 1 Vacant 2 brown 3 grey/black 4 white/black 5 yellow/black 6 grey/green Right 1 vacant 2 brown 3 grey/red 4 white 5 yellow 6 grey/green. What I remove the 3rd wire from the turn signal will the turn signal still work? I don't have the euro corners yet.

Ok note to anyone who is attempting to do this. All your pins are still on the car, all you need to do is rearrange them to the colors listed above the missing pin is hooked to the blinker. You don't need to buy the molex connector, unless your converting from us spec BUT if you want them go to the JY and snip the connectors for the tail lights, exact same connector. I got mine on and they look nice, unfortunately getting then line up with the body is near impossible, as one side was hit some time in the past and I hit the drivers side. Oh and yes I did buy the extra connector lol Can't wait till its dark and I can play with the vacuum adjust :D

Yes the turn signals will still work.
