Chrism, this is pretty simple to explain, but I sort of want to attach a photo... but... what I did was run a #4 awg and a #10 awg from the distribution block (now relocated) at the front of the unit B+ to the utilities access compartment (I jokingly call it REAM) where I fused the #10 to run both the cigarette lighter ports (dual) in the pantry (lower doors) and to a WP plug on the outside (by the other plugs) to power my Winegard CarryOut.
By running to +B I don't need 120vac. I typically use those ports for USB charger adapters at this time.
I also ran #10 and #4 ground to the frame directly below.
The #4 awg is for audio power (head unit, two amps and capacitor) located in the pantry cabinet. Where I distribute through breakers.
