Question re negative wires
Wiring - what to do with negative wires:
So, I added this larger fuse panel to make room for 2 new 12v accessories. The existing negative wires all go to marrette in a switch box that is labeled “UP for 110”. Should I bring the new negative wires here (already a bit crowded), or patch down to the fuse panel, and bring the negative down to there? Seems like it should be the latter?

Twist-on connectors are also known as wire nuts, wire connectors, cone connectors, or thimble connectors. One trade name for such connectors, Marrette, is derived from the name of their inventor and, in Canada, this type of connector is often referred to as a marrette regardless of the actual brand of the product.

first, that switch setup looks kinda sketchy, even if it is only 12v, I see the potential for shorts, and that switch is not DC rated, second, the bottom of your fuse panel has a negative bus bar already for your connections, the 12 screws, and the stud where it says "-".
get a DC rated switch and a mounting bracket, like https://www.amazon.com/dp/B07T288VN8...8c8d8ee02&th=1

This discussion is very enlightening. When we bought the Boler it actually had no fuses, but we had some added when we added a furnace. We’ve had 3 rv shops look at it and not one has said “your wiring is unsafe”. I bought the fuse box with negative wire slots because clearly that will be better than trying to gather all the negative wires in one place. I didn’t even think about the switch being an improper switch altogether. I want to make the wiring correct, but it is sure hard to find good basic learning resources for that.
