My recommendation is to maybe get some electrical safe tools, possibly some gloves that insulate against shocks, but definitely a good non-contact voltage detector, or NCV.

Check the circuit with your NCV before turning off the power, before working on the things on the circuit, and after turning on the power when you’re done (before you switch anything on). It helps keep you and your house from halting or catching fire.

… And always connect ground wires first.

Good luck.
