I was just jump starting my car and doing the normal procedure red wire to positive black to negative when I could figure something out. Red goes to positive as it’s the live wire, but if you’re thinking about electron flow then electrons travel from the negative to positive terminal so doesn’t that make the black wire the live wire?

Forget about electrons, think about energy. All wires are 'live' wires in the circuit.
