You can leave wiring as is. I've seen some people use lower female side of connectors on the single style ballast. Not sure if you need to bypass upper connectors? Or just use a new 4 prong ballast and be done.
Read my post. if you want a "cleaner look" you can install the new 2 pin ballast and clean up what's left over, wiring wise. The old wire going from resistor to the box is not needed The chances of needing a 5-pin box harness later on are nearly zero
