Just bought a 2020 Ford Edge (ST 2.7) for a Tow'd. The dealer talked us through the set-up procedure however, when I tried to follow the owner's manual (disengaging the parking brake), under para. 6. one of the steps is to "disconnect the black connection to the batterie". I'm not sure that's necessary or recommended for recreational towing (emergency towing, maybe), but the instructions aren't very clear on that issue, nor is the black post an easy location to access. Any advice? Howard
