I installed a high-power digital media receiver in my 1973T a couple months ago (Sony DSX-M80). It required a high amp connection to the battery to power its internal amplifier. To get that, I ran a 12-gauge wire from the right-side battery (with inline fuse close to the battery) back along the inner fender to the back right corner of the frunk, to a wiring harness grommet in the firewall just ahead of the glove box. Then I fished the new wire through that grommet and to the back of the new radio. That's the easiest way to get a high-current always-on connection. The yellow with red stripe wire comes from the ignition switch, so use that for the ACC connection. Because I have a high-power radio, I also ran a separate 12-gauge brown wire from the radio to the strap that I screwed into the firewall. My radio has a light sensor so it auto dims when the light inside the cabin decreases.
