amplifier connector for BMW vehicle

thingiverse

This is a 3D printable adapter that lets you swap out the rear amplifier in a BMW E46 Harman Kardon system without cutting any wires or splicing them together - just plug it in and go! The factory retention and eject system for the connector remains fully intact. This adapter also works with other BMW models equipped with the same audio system. I built this adapter using a dual-row 0.1-inch pitch header, modified by removing some pins to create electrical contacts. I soldered the header onto a carrier PCB and then fanned out the wiring to connect to the rest of the components. The .stp file is included for anyone who wants to customize the adapter themselves.
