A connector for a standards compliant communication interface between a towing and a towed vehicle comprising an ECU adapted to be connected to a vehicle CAN bus and to vehicle lights. The ECU is configurable for high speed communication. The connector is provided with a digital status detector and a high-speed communication protocol driver and means for switching therebetween in dependence on detection of an ECU for high-speed communication on a compatible connector on a connected vehicle. The connector may switch between the high-speed mode and a legacy mode. The legacy mode may be a safe mode that the system enters if there should be a fault with relevant components. The switching may be achieved by a depletion type and enhancement type FET. The standard may be ISO12098, ISO7638, ISO1185, ISO3731 or ISO11446.
