Where do you attach the negative wire for things going to the switches? Negative bus bar? It wasn't mentioned in the video or the wiring diagram. Thanks

You're absolutely right, the diagram isn't completely clear. Basically, Powertech are assuming this will be installed in a 4WD where the battery is earthed to the metal of your vehicle. The negative from your fridge or whatever load you have, etc goes to the common ground. If you're not installing in a vehicle then go to the negative bus bar.
Essentially, to make it simple, go to the common negative of your battery.
