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.
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.
