Kinda depends how much wiring you wanna eliminate. You can eliminate all the wiring on the bars, without hacking up the harness or rewiring the whole bike. Ive done a couple sporties and my dyna without doing anything that wasnt reversable. Unplugged the pod controls and spliced and 86'd some wires, but always in front of the plug, if that makes sense.
If you don't loop that run/off switch to be always on, you wont get power to the coils(wont start). If you run it together, your key switch will now be your only off switch. If you run a manual push start on your starter, that's all you need to start it.
*If you dont have the button yet and wanna see if it starts, take off the three screws on the cover and push in the shaft with a hammer handle or similar.
Hope that helps.
