Expert Reply:
The LED tail lights on your 2017 Mercedes-Benz GLS 450 will have 5 wires for the turn signal, brake light, running light, reverse light and a ground wire. You will want to use the tester that comes with the ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT to identify the correct wires for the sensors.
