How To Install a 5-Way On a 2013 Mercedes-Benz GL Using ZCI Vehicle Wiring Harness

Question:

Hello. Great video and demonstration on how to set-up this kit. One question, it is possible to connect the reverse light of the vehicle using this part? If not, is there an add-on? Thanks.

The ZCI Circuit Protected Vehicle Wiring Harness part # 119250KIT is a great no-splice trailer wiring harness for a 2013 Mercedes-Benz GL. It will provide the most basic trailer lighting functions (stop/turn/tail) which has a 4-way connector. If you need to add a reverse function then you'll need a 5-way connector. The harness is not available with a 5-way but all you need is an adapter, the Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter part # 20036 will work for this.
