Welcome to Weltmann Kfz-Teile. For the Citroën C4 Grand Picasso II and C4 Picasso II (model years 2013–2018), we supply vehicle-specific towbar wiring kits that integrate cleanly with the factory network — reliable, easy to install, and ready for modern trailer/caravan use.

Available Options

13-pin vehicle-specific kit: Full functionality incl. reverse light, rear fog-lamp cut-off, optional permanent power/charging line; typically LED-compatible.
7-pin vehicle-specific kit: Covers essential lighting (indicators, brake, tail); compact and good value.
Universal kits (7/13-pin): Budget choice for basic lighting, with fewer comfort features and limited vehicle integration.

Why choose vehicle-specific wiring?

OEM connectors & plug-and-play: No cutting or soldering — fast, tidy installation.
Comfort & safety: Automatic parking sensor (PDC) disable (kit/trim dependent), indicator monitoring, Check-Control feedback, LED support.
System protection: Designed for the vehicle electronics to reduce warnings and protect the network.

How to pick the right kit

Define your use case: Bike rack/basic trailer → usually 7-pin. Caravan/interior power → 13-pin with permanent power/charging.
Verify your vehicle: Model year 2013–2018; consider equipment such as PDC, Check-Control, LED trailer needs.
Prefer integration: Vehicle-specific kits deliver the most stable operation and best diagnostics.

FAQ – Frequently Asked Questions

Is coding required?
For many vehicle-specific kits, yes — especially to enable PDC disable, trailer detection and instrument-cluster feedback.

Do the kits support LED trailers?
Yes — especially 13-pin (and many 7-pin) vehicle-specific kits are LED-compatible. Always check the product specs.

Can I use a universal kit?
For basic lighting, yes. But comfort features and clean integration are better with vehicle-specific wiring.

Conclusion

For the Citroën C4 Grand Picasso II / C4 Picasso II (2013–2018), we recommend a 13-pin vehicle-specific kit for full functionality and future-proof performance. If you only need essential lighting, a quality 7-pin kit will do.
