Becker 4 Pin Power Speaker to DIN ISO Adapter Wiring Loom

Adaptor Cable - Becker 4-Pin Power & DIN Speaker to ISO Harness

This premium wiring loom adaptor allows seamless connection of a modern ISO-standard aftermarket head unit to original vehicle wiring in classic Mercedes-Benz and European vehicles from the late 1980s to 1990s. If your vehicle came equipped with an original factory Becker radio featuring a 4-pin power socket (for battery constant, ignition switched, ground, and illumination) alongside 2-pin DIN speaker terminals, this harness provides a clean plug and play upgrade path without cutting original wires or altering the factory loom.

Power Aerial & Console Fader Advisory

The harness includes a dedicated blue wire for connection to your electric power aerial remote or amplifier trigger. This adaptor caters for up to four speaker connections. However, if your vehicle is equipped with a standalone mechanical fader control wheel on the central console, you can bypass the console fader by connecting all four channels directly at the radio slot, or simply connect the two front channels (Left Front and Right Front) depending on your chosen speaker configuration.
