From YourSpec Automotive Wiring Wiki

ISOBUS, also known as ISO 11783 is a standard that specifies a method of interoperability between electronics systems for heavy duty equipment types that use separable implements. Technical development of the standard began in 1991 when ISO established the SC 19 agriculture electronics group. The standard was introduced in tractors and implements in 2001.
Manufacturers of ISOBUS compliant connectors include Amphenol, Phoenix Connector, Powell Electronics, TE Connectivity, US CONEC, PEI-Genesis, and Huber+Suhner.
