7-way Wiring Systems

Today’s tractor and trailer 7-way wiring systems use 12 gauge wiring for lighting, 10 gauge wiring for the stop lamp (red) and ABS (blue) circuits and an 8 gauge wire to provide an adequate ground return. All new tractors and trailers must be equipped with these sizes of wiring to provide the necessary power to support lighting & ABS systems. Multi-conductor cable in this configuration is colored green for the primary ABS cable and yellow for an auxiliary cable if one is required, and the cable of this construction that must meet the rigorous performance requirements of SAE J2394.

You can replace any lighter gauge wiring with these wire sizes as long as you use the appropriate connections such as SAE J560, 7-way plugs & sockets. Therefore, if you operate any ABS-equipped tractors or trailers you may wish to use only the J2394 type cable.
