1) Yes if there is a good battery in the trailer.
2) May be.
Be prepaired to recharge the battery(ies) in the trailer.
Also you would want to test the service brake operation and the new breakaway switch operation.
Connecting wires with wire caps is an accepted practice. Typically if there are wire caps the compoenant (in this case a breakway switch) may have already been replaced at one point since the trailer was new. You can use wire caps (or wire nuts) and my suggestion would be to seal them with a liquid sealer and then wrap with electrical tape after installation. Or use butt connectors with heat shrink tubing for the same result.
