OEM-Grade Connector Engineering
Every connection point in this retrofit kit is engineered to match Mercedes-Benz factory harness specifications. Connector housings use the same locking tab geometry as OEM terminals, eliminating play, rattle, or intermittent connection. This isn't a generic aftermarket harness — it's a purpose-built adapter designed around the specific MCU connector pinouts of NTG5, NTG5.5, NTG6, and MBUX systems. The result is a connection that feels — and performs — as if it were installed at the factory in Stuttgart.
