I purchased a connects2 adapter for A2 non Bose but it doesn’t seem to be the right one as only one black and the brown are able to be connected. Can anyone advise which headset adapter I should use?
One was a pass through for the brown plug I think - that maintained the on off with ignition function.
Mine also had a blue block which joined on to the two car wiring blocks to make a set of three in one large block which went in the three top linear connectors on the stereo (I think maybe the middle one was the connects2).
It took me a few attempts - the instructions weren't great for me.
