I was doing some research today for my upcoming dash cam timer project and I discovered, much to my surprise, that thicker gauge wire actually has less resistance than thinner wire. For some reason I thought the opposite was true since the electricity has to travel through more wire.
Now that I've been properly enlightened, is there any reason I shouldn't use 16-gauge wire versus 18-20, as long as I have a low amperage fuse that will protect the dash cam power circuit? BTW, the add-a-fuse kits usually come with 16-gauge wire, which I'll need to butt connect into, which is why I'm considering 16-gauge for the entire setup. And, as an added bonus, thicker wire usually has stronger sheathing.

I also discovered that red means 12V switched and yellow means 12V constant–well at least for stereos. So... although I wasted an entire weekend preparing for this project, I did learn a little something.
