What are the advantages of a 13-pin wiring harness?

This system is known for great reliability and it is watertight to IP 54k.
The bayonet connection guarantees easy operation.
In contrast to a 7-pin system, and in accordance with ISO 1724, this system allows you to operate all the lighting functions of a trailer, caravan or rear carrier. In addition, the extra functions and power supply for the caravan area can be transferred.
The 13-pin trailer plug connection as per ISO 11446 “JAEGER-System“ has been designed by the ERICH JAEGER team in association with the German car industry, and approved to international standards.
