Frequently Asked Questions (FAQ)

Does the CLA wiring kit require coding?
It depends on the model year and equipment. Some vehicles need activation so that lamp-out monitoring and light warning systems function properly.

Is a 7-pole wiring kit sufficient if I only need lighting?
Yes — for standard lighting like indicators, brake, and tail lights a 7-pole kit is usually enough. For reverse lights or extra power accessories, a 13-pole variant is recommended.

Can I install the wiring kit myself?
With instructions and technical knowledge, yes. For vehicles with complex electrics or when coding is involved, professional installation is advised.

Are these wiring kits compatible with all CLA models?
Please check the product description for compatibility with your car’s year, trim, and optional equipment. Our customer support is happy to help if needed.
