Frequently Asked Questions (FAQ)

Does the A-Class wiring kit require coding?
It depends on the year, trim and electrical configuration. Some vehicles require coding so monitoring systems and lamp-out warnings work correctly.

Is a 7-pole wiring kit sufficient if I only need lighting?
Yes — for basic lighting like indicators, brake and tail lights a 7-pole kit is usually enough. For rear lights, permanent power or trailer usage, a 13-pole version is recommended.

Can I install the wiring kit myself?
With proper instructions and some technical knowledge yes. For coding or more complex electrical systems, we recommend a professional workshop.

Are these wiring kits compatible with all A-Class versions?
Please check the product details for year, trim and equipment compatibility. Our support team is happy to assist if needed.
