03 s2000 clifford 50.5x door trigger issu

Just installed the 50.5x on 2003 s2000 and having some issues with alarm.

When I unlock, alarm says that door was triggered. even when it was not. 

If I open the door when armed, it triggers for door alarm.  So I think I have the right door trigger wire.  Any suggestions?

Also I've read on one of the posts that there is a 3rd Ignition wire orange, required for remote start? I checked it and it's a 10awg wire.  and the alarms 3rd ignition is 22awg.

Do I have to run a seperate wire with relay to power this wire for remote start?

I built a custom neutral safety switch using reed switch and magnet so remote start won't work when in gear.
