I have a cross-reference for the power connector on the left side of the dashboard, used for the OEM lighter/power socket!
PB045-02027 (female, this is the connector on the harness) and PB055-02840 (male, this is the connector that plugs into the harness).
You can buy them here:

and

Now you can easily add power to a handlebar accessory without wiring all the way back to the under-seat connectors, and without having to switch it from the right handlebar switch.
If you want to run a phone charger and also have the OEM power accessory, you can buy connectors to make a splitter, keeping all wiring harnesses intact. (Which is always preferred to butchering a harness)
