Plug and Play connection cable for various BMW models from the latest E-series / F-series and G-series. Required for connecting a refurbished amplifier with the "BMW HiFi" / "SA676" equipment variation. The custom connector taps into the audio signal before the amplifier and allows, thanks to the built-in Hi-Lo level converter, the connection of an RCA cable. The new refurbished amplifier can now be connected to it. The ends of the cable are already pre-stripped, and the wiring, high quality, is made from top quality copper with fine braids. The audio signal returns to the original electrical panel. The dimensions of the cable have been precisely cut for the installation of the refurbished amplifier at the rear of the vehicle. Front and rear signals are connected.
