15 Pole Connector Between Towing Vehicles and Trailers with 12 Volt Nominal Supply
This SAE standard establishes the minimum construction and performance requirements for a 15 Pole Connector Between Towing Vehicles and Trailers, for trucks, trailers, and dollies in conjunction with SAE J2742 “Combination 11 Conductors and 4 Pairs ECBS Cable”. The connector accommodates both power and ISO 11992-1 signal circuits along with dual ground wires to accommodate grounding requirements within the constraints of the SAE J2691 terminal capacity.
Rationale: This document has been developed concurrently with the SAE J2742 “Combination 11 Conductors and 4 Pairs ECBS Cable”. The connector and cable provide the system for conveying power, ground and signal to support the trailer ECBS (Electronically Controlled Braking System) and anticipated, mid-term future requirements. In addition the system will meet all the requirements of the SAE J2394/J560 system since the new connector must be compatible with non-ECBS trailers. The system is being designed with improved performance characteristics, both environmental and electrical, when compared to the SAE J2394/560 system.
