Expert Reply:

The T-One Vehicle Wiring Harness # 118747 for your 2020 Mercedes-Benz GLC 300 will only connect if you do not have the P03 premium package. The connectors for this harness are located on the tail light wiring harness located behind the access panels on both the drivers and passenger sides(see instructions linked below).

If these connectors are not present you will need the Vehicle Wiring Harness Kit # C59496. This kit includes a test light that allow you to identify the correct wires to tap into your your GLC.
