Question Adding electrical accesories to R100R

I'm trying to add a GPS mount to a '92 R100R. Next phase is tapping into the bikes wiring harness.
It looks like the GPS harness I'm using has some voltage regulation box, with an LED, so I would prefer to have that powered only when the ignition is on, or as a "plan B", have it switched. No sense draining the battery when not running...

So, looking for suggestions on best/cleanest location to tap into the wiring harness for "ignition on" only power, or if there is a supplier or after-market option for using one of the switch blanks on the instrument cluster of the 92 R100R.

Would prefer to not use the bmw accessory socket. Both because I'd rather have the wires tucked in out of sight, and I'd like to keep the socket available for electric vest.

I have the wiring diagrams from the shop manuals, but more realistically need information where on the actual bike location wiring would be a good location. of the 4 fuses, 3 seem to be switched by the ignition, its mostly a matter of picking one circuit, either at the fuse box or elsewhere in the harness.
