This electric converter allows you to change a US-style 7-pin vehicle adapter to a European 13-pin plug. Plug and play design minimizes the hassle of installing new wiring inside; no additional adapters required. Includes a dust cover on the Euro trailer side with a 13-pin plug to keep the connection clean when not in use. The converter separates the "stop" signal from the two-wire system used in US vehicles. Converts 7-pin US flat connectors on trailers to 13-pin European trailer wiring. Installation Guide: a) Connect the converter to the vehicle only after ensuring all vehicle signals are turned off. b) Connect the converter to the existing US 7-pin RV blade socket in the vehicle. c) Insert the EU trailer plug into the converter socket. d) Check that all connections are securely fastened. e) No maintenance is required during normal use.
