Universal Wiring Kit for US Vehicles – 7-pin & 13-pin Versions

The Universal wiring kit for US vehicles offers a solution to convert US standard trailer connectors into European lighting systems. Perfect for US-imported vehicles with “4-Pole Flat” or “7-Way RV Blade” outputs.

Features & special aspects

Compatible with US vehicles having a 7-pin US socket; allows connection to EU trailer sockets (7- or 13-pin).
Built-in converter/splitter to transform the combined brake/indicator signal of US two-wire systems into separate signals required under EU regulations.
Weather-proof materials and corrosion resistant contacts; strong connectors for outdoor exposure.
Easy to install – suitable for US reimport vehicles without factory wiring for EU trailer lighting.

7-pin vs. 13-pin – which should you choose?

A 7-pin EU socket handles all standard lighting and signalling: indicators, tail lights, brake lights. A 13-pin socket adds functionalities like permanent power feed, charge line and more comfort options – useful when powering accessories or towing with demanding electrical needs.

Installation & technical guidance

Check which US-connector type your vehicle has (“Flat 4-Pole,” “7-Way RV Blade,” etc.).
Route wiring safely; ensure weather-proof installation and seal all connectors.
Select appropriately rated fuses, especially if extra functions like constant power or charging line are used.
Ensure the adapter or converter meets EU lighting function requirements after installation.

FAQ – Universal Wiring Kit for US Vehicles

What is the “Two-Wire System” in US vehicles?

The US two-wire system uses one wire for both brake and turn signals. The universal wiring kit splits these signals so they meet EU regulations requiring separate brake and indicator signals.

Do I need 13-pin or is 7-pin enough?

If you only need lighting and signalling, 7-pin is sufficient. Use 13-pin if you need extra features like constant power, charging lines, or reverse lights.

Is installation complicated?

No – for most vehicles with a pre-existing US socket, installation involves plugging in the adapter, protecting connections and adding appropriate fuse. If unsure, professional installation is advised.

Will installation affect warranty?

No – provided you use certified, universal parts and avoid modifying factory electrical systems inappropriately. Keep documentation of the installation.

Which US vehicles is this universal kit suitable for?

Vehicles with US standard connectors such as 4-Pole Flat or 7-Way RV Blade, including US-imports from Chevrolet, GMC, Ford, Dodge, etc. Check your vehicle’s connector type before purchase.
