I have the Admore kit on my E460 on the Strom. I also used the Eastern Beaver connector that connects under the tail section. Admore lighting kit LED360/460-T-TS Givi E460

I also have an Admore kit in my E55 Maxia case that I sometimes run on my Valkyrie.

The Admore kits come with their own bulkhead connectors so that the case can be easily removed. I don't know that I'd use the same connector for a 12v charging source; the pins and wiring to them is a pretty thin gauge, since they're only powering LEDs. The connector style they use is very much like these (right angle connector that threads to the receptacle on the case): https://www.ods-tech.com/en-gb/product-category&path=121 with dip switches integral in the wiring.

This company does also sell the same type connector for higher amp usage. Rather than reconfigure the Admore harness, I'd probably wire it as they intended and add another plug with a higher rating for my 12V power feed.

Connector aside, I am not sure the tail lights circuit can supply enough juice to charge anything, while also operating all the lights.

I agree, and you wouldn't want a phone/gps/whatever to draw a bit too much and pop the fuse for the tail lights. If anything, I would add a separate 12v plug from a dedicated accy source that is it's own (aftermarket fuse box) or a circuit that isn't critical.

I have a "lighter plug" that is in the storage area behind the battery, and I never use it. I have a USB connection on my handlebars that I plug my phone into if need be for using Google Maps or just to charge. No real need for any other, for me anyway.
