After market Trailer Hitch for GLC 300
#26
It looks like a notch should have been cut in the plastic above the hitch. It looks like it's just bent up instead. I guess it won't hurt anything but that would bother me,

Still no joy - anyone have tips/tricks for wiring?
As mentioned previously, we also bought the recommended drawTite wiring kit from eTrailer and used the WireTaps another member suggested. When the module is powered but not connected to a trailer the signaling seems to be ok at the 4 flat plug, but when attaching a fresh out of the box trailer lighting rig and grounding that the car detects a rear brake light failure and none of the signaling/lights work properly until disconnected and the car takes a few minutes to reset. Does anyone have tips/hints on how to connect the drawTite module to the wiring harness? We are trying to not have to hard splice the wiring loom as we still have 20 months under MB’s CPO warranty. The WireTaps appear to work as expected - just wondering if there’s anything special about power/grounding. One member posted they ran power all the way from the battery? We are pulling 12V from a spare lead in the electrical fuse panel embedded In the rear cargo area. Appreciate any tips/tricks - can’t be this hard, can it? FWIW - this is 2018 GLC 300 with “Premium Pkg” - thx!!
