The NSS is just a simple open/close switch. If you disconnect it (I think there is a connector nearby) and jump the two terminals, you have bypassed the switch.
If the car starts with the jumper across the switch, it's bad.
Keep in mind that many switches die and prevent the car from starting ONLY in Park (they will start just fine in Neutral) BUT mine didn't do this. It wouldn't start in Neutral either. I entirely overlooked the NSS because I thought that wasn't the problem (since the car didn't start in Neutral either).
NOTE: Do NOT leave the switch jumpered for any period of time. Wouldn't want your wife or any one else starting the car while it's in Drive and running over/into something or someone! If the switch is bad, order the new part ASAP and make sure you are the ONLY one who drives the car.. hide any other keys to the car for a few days.. it won't hurt!
