From what I’ve read, it’s to allow the pick up and hang up buttons to work when installing the aftermarket headunit.
The original harness is normally plugged into the Bluetooth module which is behind the seat. Once you unplug the harness, the adapter bypasses a few pins thus allowing the pick up and hang up buttons to operate.
That’s my rudimentary understanding of it.
