2025 R1S 12V Power Source?

[bobgonline]

Hi - I’m almost finished with my subwoofer install on my 2025 Gen 2 R1S, except I can’t find a switched 12V power source??? Older R1S vehicles have a different wiring harness in the spare tire well (ref. the Alpine sub install), and I don’t seem to have the fuse box like the Gen 1. I’ve tried tapping the trailer brake power, but the ‘smart’ electrical computer dumbs the voltage down to 5V when I connect the amp load to it. I need a good source I can tap and put a fuse on it and run a good size wire to the amp. Appreciate any advice.
