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.

Looks like your head unit is double in power so my set up will be basically the same (12gauge wire, ground, etc...):
My stereo specs:
My question would be (from earlier in the post) is I tested a wire, original from the car, and would that be safe to use for this head unit as the ACC wire?
Once the car is on, if I am correct, the power for the head unit comes from there and was thinking on upgrading that wire/connection also. The factory harness wires just seem so old and small.
Hope that is a valid concern...been a learning experience this week with the wiring here, pulling the alternator, new ignition switch and starter...so much relay research
Thanks for the patience...stereo is secondary BUT want to do it right.
