Push Button Start

I had to "hot wire" my B body for awhile so I could figure out some electrical stuff. I did as described above routing a hot wire to the starting wire on the relay and used a inline momentary button to start it. You will still need the key though for powering it down. My steering column had no wires so I had to use on on/off toggle.
I would think if you had the key in the "on" position, not "start" and used the push button to start it, it wouldn't even affect the NSS as long as it was in P or N.
But I definitely agree to use the NSS if you can.
I liked the push button, it made it feel like a race car instead of the rusty Charger it was. Ha
