Removing the starter is not necessary at all, and you don't have to disconnect the batteries. If your near the starter wire, you're doing it wrong. You access the passenger side plug by going up the side (well behind the wires) and over the starter.
Properly accessed, a person is just nowhere near the starter terminals and wires.
I've done this three times now, so I'm pretty familair with the procedure, and removing the starter is just a waste of time and energyt
