If you want some additional info on this:
1) I ordered this connector in Jan. 2023 for the '22 C 400 GT that I owned at the time:
2) In Oct. 2023, I ordered a less expensive version of the same thing, for the '23 C 400 GT that I now own:
Use leads 1 (earth) and 3 (power) and ignore lead 2 (speed pulse not required for non BMW systems) - leads are numbered. 1 Connector Wire. Item do not fit your motorcycle perfect. For repairing main wiring harness.

3) If you look at my personal C 400 GT gallery, in this particular image and caption, I identify the locations of the ground and hot (and unused) wires in that connector for you:
4) Starting with this particular image, I also have some nice clear shots of where you'll find that unused connector (which is intended for a BMW GPS):
5) Note that that connector is hot for exactly 60 seconds after the bike is turned off, so don't be freaked out, don't think you did any wiring wrong, when whatever you connect using that power source stays on for one minute after the bike is shut down.
