Mercedes W115 US to Euro headlight conversion

Hi All,

New poster here, long time follower.

I have a 1971 US-Spec W1115 220. I recently got a near mint pair of Euro headlight from Germany (in original Hella box!).

Euro Headlights are part number ER 001 166-81 1 They are the H4 headlight with H3 fogs.

I'm looking to make the switch over and have some questions about the correct re-wiring. Hoping someone here has done it and can give some pointers. I've searched these forums and elsewhere on the web extensively with no definitive wiring diagrams to be found.

My US car has a 6 pin assembly (5 in use) + another 2 pin assembly for the side marker lights.

Euro headlights have a 6 pin assembly (4 in use).

I have tracked an labelled all the pin in the Euro assembly and need to know which pins to move in the US 6 pin assembly to match + which wires to jump for correct operation of the parking/fog/city lights that are on the Euro assembly but not on the US one.

Euro assembly pins are
(with locator pin on the left, numbered across the top row and then second row-
1- empty
2- Grey - goes to main H4 headlight
3- Black/green - goes to 21W turn signal lamp
4- Grey/Green - goes to H3 fog/city
5 - empty
6 - Brown - Ground. goes to turn signal lamp, main H4 headlight and H3/4W fog/city

There is also a green wire going to the 4W fog/city light that isn't connected to anything.

US lights have 5/6 pin in use, not sure where the wires go/colors as haven't opened the connector. Empty is pin 5.

Any advice? Pics attached.

I have a general idea of what needs to be done (move pins inside the US 6 pin connector) + splice some wires together for the fog/city lights + side marker lights, but would greatly appreciate any advice if someone has done this before. Will save a lot of texting and fiddling with a multimeter.
