The Ingineerix YouTube channel has some really great Model 3 videos. Apparently, he bought a crashed Model 3 and took it completely apart, though kept all the systems operating.

Instead, these two are some of his latest ones which just simply shows you how to get a switched 12-volt feed for accessories.
