The Aerpro CHMERC Steering Wheel Control Harness (SWC) enables the seamless use of your vehicle's factory steering wheel audio controls with an aftermarket head unit. By converting the original commands into a format recognizable by an aftermarket stereo, this harness makes upgrading your audio system easier.

Designed specifically for Mercedes C-Class, E-Class, SL, and CLK models with an interior CAN-Bus and OEM head units (10-PIN ISO connector), it eliminates the need for complex wiring modifications. Pair it with the appropriate SWC patch lead (sold separately) to match your new head unit brand and connector.
