Wiring USB behind the dash

Per this video, it looks like there's a harness connecting the cigarette socket.

Is there an existing harness to tap into (and use a 12V step down to USB @2-3A) to provide USB power on top of the dash (to power on-dash devices)? Perfectly fine to piggy back onto a blade connector, but it doesn't look like that'll work. I'm also thinking about splitting that into two circuits to power a ham radio HT (2A on TX) as well, but might use another tap for that. Would be great to provide power on top of the dash, but it's not a deal killer (or at least have the wires coming out of the sides of the console at worst); trying to avoid cables dangling in front of the center console. Thanks!
