2014 GL350 Connecting Prop Brake Controller
Connecting my 2014 MB GL350 w/factory tow package to Prodigy 2, electronic brake control (Prop Brake Controller).
under dash connector (4 wire) for Electronic brake controller does see power associated with brake light. Appears to require setup in ECU(?) to enable circuit. MB factory tow package with 7 wire connector. Local MB Dealer Service Department wants to rewire.... Should be as simple as enabling towing circuit.
