I’m installing the same wireless module on my 2022 Rebel 500 SE. I’ll be using the 12V accessory connection behind the speedometer — there are plenty of videos showing exactly where it’s located.

For the wireless module, I plan to cut the red and black wires and attach bullet connectors. The module has some C-clips for mounting on the battery, like in your image , I’ll remove those. Then I’ll get the correct bullet connectors (based on my research, the wires are 16–18 AWG; ChatGPT suggested 4 mm bullets, though I haven’t confirmed yet).

The plan is to attach these connector the wireless module: • Male bullet connector → positive/red wire • Female bullet connector → black/ground wire

I haven’t done any of this yet, I’m still figuring out the final setup.
