I would physically check the NSS with a multimeter. If your drivetrain is already in the car, The NSS is on the top of the trans about 3/4 of the way back towards the shifter. The harness runs down the drivers side of the transmission, it is a two pin plug (I think it's white). If you have the right NSS it will be closed in gear and open in neutral. Hopefully you have the right one. It is a real PIA to change it,, but it can be done without completely removing the trans.
