About this file

The document is a trailer wiring diagram technical specification from the Michigan Department of Transportation (MDOT), specifically detailing the standard J560 connector pinout for non-tractor/trailer, non-ABS truck-end electrical connections. The diagram, revised on 03/04/2015, provides a comprehensive visual and textual breakdown of the seven-pin connector, including color-coded wire functions such as white ground return, black key-on power terminal, brown tail and marker lamps, blue electric brakes, yellow left turn directional, red stop lamps, and green right turn directional.

The technical specification appears to be a standardized wiring configuration for vehicle electrical connections, ensuring consistent and reliable trailer-to-towing vehicle electrical interfaces. By specifying precise pin assignments and colors, MDOT establishes a clear technical standard that enhances compatibility and reduces potential electrical connection errors in vehicle and trailer systems. The diagram is intended for use with all non-tractor/trailer, non-ABS truck-end configurations, viewed from the wire side of the plug, which suggests it is part of MDOT's vehicle equipment and infrastructure technical standards.
