Ok so any idea what this connection is used for

[PODMAN]

Old Fart Newbie suggested I may have better luck getting an answer on this if I start a new topic so here goes.I relocated my NAV VI to above the TFT utilizing the mhornig GPS mount. In loosening the cable that attaches to the GPS holder I found a second cable (second pic white connector). In the first pic you a see a single cable (bottom of first pic) which then splits into two cables. The left cable is the one that goes to the GPS holder and provides power , wonder wheel use etc.) the second cable with the white connector is my question. What is it used for or what can be connected to it? Thanks

I've never found it on a wiring diagram, but that connector is generally believed to be the connection from the Navigator mount to the RT audio system.
