Brake Light Wire on 2015 Mercedes GLK 350 to Install a Trailer Wiring Harness
Updated 12/19/2016 | Published 12/17/2016
Question:
Tester accurately detects Land R turn wires, but when braked, both turn signal liters hit tester, but no other terminal does. What do I do for the brake connected?

In some situations on vehicles with multiplex wiring systems like your 2015 Mercedes GLK 350 the brake light signal can only be obtained at the center high mount stop lamp. So if you cannot find the right circuit at the tail lights then try the third brake light at the top, center of the rear of the vehicle.
