That shouldn't matter. When you look at the wiring off the ignition switch, there should be 4 wires from the alarm/remote start going there. 1 will be spliced into a constant hot, 1 will be spliced into a switched hot. For the last 2, you will see that the factory start wire has been cut in 2. 1 side will go to the key side of the wire, and 1 will go to the starter side of the wire. If that is the way it's wired up, you can remove the constant hot lead and the switched lead. Remove both wires to either side of the starter wire and put the factory wire back together.
Scotch Plains is very far for me and I also have a fish to fry with my stang(vibration in rear that just started), but if you can take a pic of the underdash wiring along with any questions, I'll try to walk you through it.
