Does anybody know where is the connector for the brake controller. I have the pig tail that comes with the vehicle (in a bag at the glove box). And that connector doesn’t fit any of the connectors of the vehicle. The installer opened the “coin change holder” and there is a plug hidden behind it, but that connector is very small, non compatible with the with the pig tail provided by Ford. I called the dealer and the original Trailer Brake Controller is not available for ordering yet. I have a gorgeous new truck and I can not tow with it. Help!!!
