FAQ – Volkswagen T-Roc Wiring Kits

7-pin or 13-pin—which is better?

Use 7-pin for lighting alone. For power circuits or additional consumers, choose a 13-pin kit.

Do I need permanent live?

Only if you plan to power accessories like interior trailer lighting or chargers. For basic lighting it’s optional.

Does it support lamp failure monitoring?

Yes—our kits detect bulb issues and report faults properly if your vehicle supports that function.

Is coding needed after installation?

Often yes, particularly in vehicles with advanced systems or sensors. Coding enables full functionality and prevents warning issues.

Can I install it myself?

With technical skills and proper tools, yes. But for optimal wiring, safe connections and full system integration, professional installation is recommended.
