Can’t help with the other stuff, as electrical issues aren’t my specialty… but you’ll find those square-head screws are common in the RV industry. To turn them without stripping, you’ll want to get what’s commonly known as a #2 Robinson bit driver.
If you have a multi-bit driver in your kit already, chances are you’ve already got one. Most of them that I’ve seen come with 3 different size square bits… and you’ll want the middle size.
But to make things easier on yourself… head out to Lowes, Home Depot, or local hardware store and grab a couple of dedicated Robinson drivers: one long… one stubby.
