To tow a trailer with electric brakes with your 2018 Mercedes-Benz GLC 300 you'll need an electric brake controller. I recommend the Curt Echo Under-Dash Trailer Brake Controller # C27JR along with the Universal Wiring Adapter for Curt Trailer Brake Controllers # C51515, which will splice into your factory wiring allowing for a simple plug-in of the # C27JR.

The Bluetooth function of this brake controller will allow you to use your smart phone or tablet to control and monitor your braking system.
