The Acv D-57-1043 ISO-bypass adapter connects to the factory radio wiring harness in Citroen, Opel, and Peugeot vehicles. It allows the power supply and speakers to be disconnected without damaging the original wiring, while leaving the factory radio unit’s operation unaffected.
The adapter can be used to add hands-free equipment, power amplifiers, or high-to-low converters. In vehicles with amplified factory systems or speaker impedance monitoring, its functionality may be limited or unavailable. The red wire connects to the ignition-switched +12 V terminal, with a fuse in the fuse box.
