An electrical interface device (10) for towing, operable to facilitate releasably coupling one or more electrical subsystems of a towing vehicle (12) and a towed vehicle, and including associated modular, removable circuitry (24). The circuitry (24) may provide overload, short-circuit, and reverse connection protection and power signal filtering. Alternative or additional circuitry may be added to support other functionality, including interfacing a brake control subsystem. Circular receptacle and flat plug connectors (20,22) are provided to accommodate without modification a variety of electrical connectors. Covers (32,33) are also provided to protect unused connectors from adverse environmental conditions.
