Recommended Wiring Harness For 2015 GLK-350 Base

Question:

I purchased a Curt C59236 trailer lighting kit for my vehicle from you folks, which I was told was the correct one. I had it wired by a shop that does all my work, and when I hook up the trailer, when I use the left blinker, both trailer lights blink, and when I try the right blinker nothing happens. This is a standard trailer with LH and RH stop and turn as the same lights.2015 GLK-350 Base These guys spent a lot of time trying to make this work, but I figured I would ask the experts what to try next. Thanks

The Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C59236 is not confirmed to fit your 2015 Mercedes-Benz GLK-350. It is a confirmed fit for the 250. The only wiring harness we have to fit your GLK-350 is the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT. This wiring harness uses zero-contact-interface sensors, so there is no wire splicing, but it will require a power lead from the battery.
