• appropriate wire length and geometry for the rear of the vehicle,
• mounting point placement consistent with original routing.

This ensures a tidy installation without the need for electrical system modifications or additional adapters, maintaining consistency with the car's original electrical architecture.

Condition, Service Application, and Benefits of Installation

The offered harness is a used part, making it an attractive service solution for SLK R172 owners seeking original wiring at a reasonable budget. It is particularly useful in situations where:
