Perävaunupistorasia IWH KFZ 13-napainen 20 A 12 V – ajoneuvon perävaunupistoke

The IWH KFZ 13-pin 20 A 12 V trailer socket is designed to provide a standard, reliable electrical interface between a towing vehicle and a trailer. Compatible with 12 V vehicle electrical systems, this 13‑pin socket supports lighting circuits and auxiliary power lines in a single compact unit. It is engineered for common towing applications where secure signal transmission and stable current handling up to 20 A are required.

Advantages

This 13-pin trailer plug combines a standardized pin layout with current capacity suitable for most passenger vehicle towing needs. The construction delivers consistent contact pressure for secure electrical connections and reduces the risk of intermittent faults. The socket is compact and intended for straightforward mounting on trailers or tow vehicles, facilitating correct trailer electrical integration and easier maintenance.

How to use

Mount the socket in an accessible, protected position on the trailer or towing vehicle and secure it according to the mounting provisions. Wire each conductor to the corresponding circuit on the vehicle harness following the 13‑pin standard pinout: lighting, indicators, 12 V auxiliary supply, and ground. Ensure all connections are tightened and insulated to prevent moisture ingress. After wiring, test each function — left/right indicators, brake lights, tail lights and auxiliary power — before regular towing operations.

Recommendations

For reliable operation, periodically inspect the contacts for corrosion and clean as needed. Use dielectric grease on contacts to reduce oxidation and ensure secure mating. Replace the socket if contacts show excessive wear or if electrical faults persist after tightening and cleaning.
