Turn signals on the trailer didn't work?
Here's the layout of the lights (courtesy of @DV52 on other message boards)
I'd take it you're looking for A60 and C31 in the wiring diagrams - that'd be what you need to mate up to the turn signal wires on your trailer wiring harness.
Ok - forget that; don't think that's much help (at least not directly here); this would help if trying to change the coding for any of the lights, so I'll leave it there.
Try this:
M6 is listed as the "left rear turn signal bulb", so black/white wire in position 1 on the OEM connector.
Over on the other side, M8 fits the description - black/green in position 4.

Nuje! Big help. I tried to depin the harness until the turn signal stopped then I figured I would move the green interceptor wire over to that pin which would get me turn signals. My depin tool then snapped, just ordered another and will read your post in depth fully and get this sorted. Much appreciated
The more I think about this... may have to go back to original coding on the turn signals. How else will I get brake and turn intercepted on one pin? I would have to get a fancier harness lol

finally got the part down here and installed the 118646 on a 2016 tdi variant. did the modification as shown but I have no clue how you could release those pins I had a generic pin removal kit and could not get any to release so soldering gun and shrink wrap to the rescue. so added 20 extra minutes to the install. Just wanted to note here the variant does work with above noted Grigg3 mod for people in the future. Thanks all and Grigg3Thanks for the picture. Couldn’t see the diagram linked earlier, and wasn’t following along on how to do it with just words.
Looking at the connectors as supplied, and as modified, it’s real simple to figure out.
The yellow moves over to the third slot and green moves to the second, from original locations at one side.
Just modified mine, haven’t installed and tested.
Didn’t have a tool to remove the wires and improvised with a little piece of aluminum sheet metal cut real narrow, did the trick. A piece of steel sheet metal would have been better, but it’s not so difficult that soft aluminum can’t work, “tool” shown as well. Photo uploaded to the forum, hope it stays visible for a long time.
