Trailer Wiring Harness for 2014 Mercedes GLK350

Updated 05/09/2016 | Published 05/07/2016

Question:

I just installed the hidden hitch from etrailer and it installed perfectly. Please confirm if 119250KIT is the correct wiring harness kit for my 2014 Mercedes GLK350. If so, are there any other components required to complete the installation to connect a Uhaul trailer? Are there any alternative kits? I require one that would not void my warranty. Also, can you provide an installation video or explicit instructions? I would like to review before ordering.

The ZCI Trailer Wiring kit part # 119250KIT that you referenced is a confirmed fit for your 2014 Mercedes GLK350 as it can basically be installed on any vehicle and since it does not require cutting or splicing into the vehicles wiring it would not void any warranties either.

Instead of splicing into the wires the sensors of this kit just clamp around them and sense that voltage is being carried on the wire and that is what is used to signal which trailer wiring circuit needs to activated. You will need to run a power wire up to the positive post of the vehicle battery as well though.

We don't have specific instructions for this kit, but you will use the included circuit tester to test the circuits for function and then install the kit accordingly.
