Abstract: An electrical interface device (210) is provided for disengageable or removable coupling with an existing master connector substantially non-removably mounted on a towing vehicle in order to allow for the connection of the electrical systems of differently configured towed vehicles without any modification of the device (210). The device (210) comprises a first end (218a) presenting a first master connector (222) and a second master connector (224), and a second end (218b) presenting a third interface connector (225). An alignment mechanism (229) ensures proper alignment, and a locking mechanism (231) avoids inadvertent uncoupling of the device (210) from the existing master connector. In use, the second end (218b) of the device (210) is coupled with the existing master connector, and an electrical connector of the towed vehicle is coupled with the first or second master connectors (222,224), thereby slaving the electrical system of the towed vehicle to that of the towing vehicle.

Abstract: A towing connector (10) operable to electrically couple a towed vehicle's (12) wiring with any towing vehicles (14) wiring broadly comprises a housing (20,120), a plurality of wires (26) within the housing (20,120) and electrically coupling a first receptacle (22,122) with a second receptacle (24,124), and a mechanism (54,154) operable to modify an electrical arrangement of the wires (26). The mechanism (54) preferably comprises a plug (56) removably mounted within the housing (20) and a mount (58) fixedly mounted within the housing (20). The plug (56) may be removed, rotated 180 degrees and reinserted within the housing (20), thereby modifying the electrical arrangement of the wires (26). Alternatively, the mechanism (154) may comprise a double-pole double-throw (DPDT) switch (188) disposed within the housing (120).
