I agree with Jerry and that’s how I wired my uBitx up except I added a separate switch for the PA.

The hfsignals WireUp instructions for power into the rig at the top of http://www.hfsignals.com/index.php/ubitx-wire-up/
have a symbol that looks like headphones.
Some have mistaken it for a fuse, that's definitely the wrong position for a fuse.
The label on that symbol says "On/Off", so we can assume it's a power switch.
Here's an old post showing how I wired mine up:

My preferred solution:
The instructions for reverse polarity protecton on the uBitx WireUp page would be acceptable
if they also showed a 3 Amp fuse in line with the +12v lead from the power supply.
