This kit is plug-and-play on all USA models (2021-2024) https://www.amazon.com/dp/B0BHGSVW1VDo you have a link to the "plug and play" USB port you used? I'd love to add one to mine but everyone I've found had feedback saying it wasn't plug and play on our 24s.
The ones that don't work with the USA models are ones that use the blue accessory power plug inside the headlight bucket, because that plug is missing from the USA model bikes. It exists on the Japan and Canada model bikes. Without the plug they aren't plug-and-play, but can still be used with some DIY wiring.
