GLK350 - Factory hitch install or aftermarket?
This is the left side rear tail light assembly plug from my 2013 GLK250. I tested all with a test meter and confirmed these. Very easy to check with a volt meter.

The picture I took was the left side. The right side is the same in that the tail light wire is next to the pin with no wire, turn-brake is two over, and reverse is at the end opposite of where the pin with no wire is.
Good luck (if you haven't done it already). Was pretty easy.
Many thanks again for your help

I have a 2015 with a warranty that goes to 2021 (unlimited miles). I didn't want to ruin that.
Anyone need a MB GLK350 trailer hitch?
Has anyone experienced creaking noises coming from the hitch area when accelerating the car kind of hard in 1st and 2nd gear? I suspect the minor warping of the body which may occur in these circumstances may cause some rubbing with my aftermarket 3 point hitch. I do not think there is actual contact with any part of my exhaust. Any thoughts would be appreciated.

The only one I've seen that seems to blend in well with the look and aesthetics of the car was the e-trailers one (https://www.etrailer.com/vm/Mercedes...LK-Class/hitch), which also has quite a few pictures that helps give an understanding of how it'll look installed.
So please sound off; what brand did you like, didn't like and pics if you like it.

The pictures from CERNICAO1's post above worked perfectly for my 2013 GLK350. I also watched the eTrailer video (red GLK). Install went super easy. Instead of fishing the wire under the left and right side areas in the trunk, I just removed the tool kit (2 bolts) on the left side and the plastic compartments (2 bolts and 2 nuts) on the right side. That allows you to run the wiring without needing a way to fish under the plastic pieces. For the wheel well to the engine bay, I used a coat hanger to fish the wire up.

I believe the GLK in the video is older without the LED tail lights, so I disregarded the wiring portion. Again, for 2013 - 2015 the pics above are spot on. For earlier without LEDs, I'm guessing the video's wiring is correct The remainder of the install is identical.
