70 Dart s6 to 360 project

In converting from points ignition to the electronic with added MSD, should I change my old wire loom to a factory reproduction one for electronic ignition? This would require the right resistor and control box, unless the MSD replaces all that (I have never had one before). Also, some original wires may not reach areas on the 360 that they did on a slant six, and I will be adding a wire for an electric choke. My project is also posted under this same name in Member Restorations.
