Wiring harness kits for trailer towing devices

A wiring harness kit for trailer couplings electrically connects the trailer and the towing vehicle. Wiring harnesses are classified into 7-pin and 13-pin models. Both models are available as vehicle-specific or universal wiring harness kits.

ERICH JAEGER offers wiring harness kits with a 7-pin trailer socket according to ISO 1724 or with a 13-pin trailer socket according to ISO 11446. Today, the 7-pin socket still has a high diffusion rate concerning simple requirements in retrofitting. The automobile industry primarily uses 13-pin systems.
