Hello, I'm trying to figure out exactly what parts I need and how to find them for a charging project for my 2017 AT. I have a 12v to usb adapter in my top box that I want to connect to my Eastern Beaver fuse box system. The challenge I'm having is I want to connect them to the bike without having wires that I need to plug and unplug when I take the box on and off. I want to set up contact connectors, similar to what you find with removable phone batteries or helmet headset connectors but I cannot find the type of contact plates I need. I also do not know the gauge I'd need to meet the amperage requirements without melting them but I am not sure what the maximum draw will be from 2 usb devices will be. So any help, advice, suggestions, etc. would be greatly appreciated. Thanks in advance, y'all!
