Installation guide for a third-party USB adapter. This USB adapter from Interphone features 2 USB ports that support fast charging (5V 2A). This video shows in detail all the necessary steps to install this USB adapter without cutting any cables or doing any other permanent damage/changes to the motorcycle.
About the connector: After A LOT of research online, I found out a code (6188-0004) for the connector that fits in the motorcycle's accessories plug. After a lot of time and many refunds, I managed to buy a set of these connectors from AliExpress.
About the "creative" solution for connecting the USB adapter: This solution is not ideal, however, I've used it for a while without any problems as a temporary fix. If you want to connect the adapter like this, just make sure the wires don't touch and isolate everything carefully.
