FAQ – Volkswagen Jetta V Wiring Kits

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

7-pin is fine for basic lighting. Choose 13-pin if you need permanent live, a charging line or extra accessories.

Will coding be necessary after installation?

Depending on equipment, yes—especially with PDC or bulb-failure monitoring. Coding prevents warnings and enables comfort features.

Does the kit support bulb-failure monitoring?

Yes—our vehicle-specific kits are designed for CAN-Bus integration and report lamp faults correctly where supported by the car.

Can I install the kit myself?

Skilled DIYers can install many kits. For perfect integration and any required coding, a professional workshop is recommended.

Do I need permanent live?

Only if you power accessories (e.g. caravan interior lights, cooler, charger). It’s not required for basic lighting alone.
