Permanent live option: Useful for interior lighting, charging or powering devices in the trailer.
Durable connectors & weather-proof design: Quality contacts and protected cables for long service life, even in external conditions.

Which variants are available?

We offer both universal and vehicle-specific wiring kits for the Passat B5 / B5.5 (Typ 3B / 3BG). Options include integrated PDC deactivation, Check-Control modules or universal socket kits. Use filters for year, pin count, and equipment level to find your match.

FAQ – Volkswagen Passat B5 Wiring Kits

Which should I choose: 7-pin or 13-pin?

7-pin is enough for basic lighting. Use 13-pin if you need permanent live, charging or extra accessories.

Will the kit support lamp-failure monitoring (Check-Control)?

Yes—if the wiring kit supports it and your vehicle has the hardware, lamp failures are correctly detected and displayed.

Is coding required after installation?

In some cases yes—especially for vehicles with parking sensors or comfort/electronic packages. Check the product description carefully.

Can I install the wiring kit myself?

If you have basic electrical skills, yes. For clean installation, weather protection and ensuring safety, professional help is often better.

Do I need permanent live?

Only if you plan to run powered accessories like interior lights or chargers. Basic lighting works without permanent live.
