^^
i just did that set up.
it shakes some, but maybe thats just cuz of my boomba RMM
location wise, i have it just a tad lower (to try and reduce the vibration/shake)
seems like a good spot.
i ran the cord over the airbag and then looped the excess around my hand and then ziptied it so it wouldn't unravel. then pushed that bundled excess kinda under the ac vent.
i literally did this not even 5 minutes ago.
keeps it all out of the way and looks tidy
