This SAE Standard provides the minimum requirements for Automotive or RV, 7 Position, Self-Draining Trailer Tow Connector Interface. The procedures included within this specification are intended to cover the test methods, design, and performance requirements, of the electrical interface of the 7 position trailer tow connector in low voltage (0 to 20) road vehicle applications.

This SAE Recommended Practice covers the wiring and rectangularly shaped connector standards for all types of trailers whose gross weight does not exceed 4540 kg (10 000 lb). These trailers are grouped in SAE J684 with running light circuit loads not to exceed 7.5 A per circuit. This document provides circuits for lighting, electric brakes, trailer battery charging, and an auxiliary circuit color code and protection for the wiring from hazards or short circuits. Color code is compatible with SAE J560 and ISO 1724-1980(E).

SCOPE Procedures included within this specification are intended to cover performance testing at all phases of development, production, and field analysis of electrical terminals, connectors, and components that constitute the electrical connection systems in high power (20 V to 600 V and/or >80 A) road vehicle applications. These procedures are applicable only to terminals used for In-Line, Header, and Device Connectors and for cable sizes up to 120 mm2 (4/0). In cases where power levels are mixed in the same connector, (i.e. sensing or normal 14.5 V system circuits with High Power Contacts) the High Power Contacts must pass SAE J1742 requirements, and all other contacts must pass SAE J2223-2 requirements. The connection system (housing and high power contacts) shall meet SAE J1742 requirements. The requirements and procedures in this document are not intended for connections internal to electrical/electronic modules or complete subassemblies.

This SAE Standard covers general requirements and dimensions of various sizes of eyelet and spade type terminals.

This SAE Standard covers general requirements and terminal interface dimensions of various sizes of pin and receptacle type terminals.

This SAE Standard provides the auxiliary requirements for automotive or RV, additional 12 position, sealed Trailer Tow Connector Plug and Receptacle. The information included within this specification is intended to cover the test methods, design, and performance requirements of optional features for additional power, clean ground for electronic functions, video, data communication, and supplementary electric brake control.

This SAE Standard provides the minimum requirements for Automotive or RV, 7 Position, Self-Draining Trailer Tow Connector Interface.

This SAE Standard specifies dimensional characteristics of flat blades of single-pole connectors and specific requirements for on-board electrical harnesses of road vehicles, which can be fitted into female connectors such as those given as in Appendix A. This document applies to connectors designed to be disconnected after mounting in the vehicle in the case of repair and/or maintenance only.

This SAE Standard defines dimensional characteristics of existing flat blades of multipole connectors and specific requirements for on-board electrical harnesses of road vehicles. This document applies to connectors designed to be disconnected after mounting in the vehicle in the case of repair and/or maintenance only.

Blade terminals listed in this SAE Recommended Practice may be used for terminating wire ends, or for terminating circuits on devices other than wire.

Procedures included within this specification are intended to cover performance testing at all phases of development, production, and field analysis of electrical terminals, connectors, and components that constitute the electrical connection systems in low voltage (0 - 20 VDC) road vehicle applications. These procedures are only applicable to terminals used for In-Line, Header, and Device Connector systems with and without Shorting Bars. They are not applicable to Edge Board connector systems, > 20 VAC or DC, or to eyelet type terminals.

This SAE Recommended Practice defines test methods and general requirements at all phases of development, production, and field analysis of electrical terminals (including sense pins), connectors, and components that constitute the jump-start connection for road vehicles having 42 V (nominal) electrical systems. The 42 V jump start connector is always remote from the vehicle battery and may take the form of an in-line or Header Connection, either of which is in an accessible location for attachment of a jumper cable from an assist vehicle or battery charger. WARNING—The Jump Start Connector requires environmental protection. This specification assumes that such protection is in place and remains effective for the life of the vehicle. The level of protection depends on the vehicle packaging environment and duty cycle. Appendix B of this document contains the physical specification for the Jump Start Connector.

This SAE Standard defines test methods and general requirements at all phases of development production, and field analysis of electrical terminals, connectors, and components that constitute the direct connection to the storage battery of road vehicles having 42 volt (nominal) electrical systems.

The SAE Recommended Practice covers the application requirements for terminals and splice clips attached to stranded low tension wiring and cable as shown in SAE J1127 and SAE J1128. In addition, it covers maximum voltage drop limits for friction type connections.
