Neutral Position Sensor.
It's not technically needed. It was added around '85 or '86 and is basically used to tell the computer the trans is in nuetral so it may dump codes

If I remember right the switch is tripped in 5th gear to tell the computer to go to the highway/fuel saving strategy.
I've never heard the neutral switch theory before.

No working neutral safety switch and you will get a code 67.
Code 67 - clutch not depressed (5 speed) or car not in neutral or park (auto) or A/C in On position when codes where dumped. Possible neutral safety switch or wiring problem. This code may prevent you from running the Key On Engine On tests. You can generally ignore this code, since it has no effect on engine performance.
The computer wants to make sure the A/C is off due to the added load on the engine for the engine running tests. It also checks to see that the transmission is in Neutral and the clutch depressed (T5, T56, Tremec 3550 & TKO)). This prevents the diagnostics from being run when the car is driven. Key On Engine Running test mode takes the throttle control away from the driver for several tests. This could prove hazardous if the computer was jumpered into test mode and then driven.
The NSS code 67 can be bypassed for testing. You will need to temporarily ground computer pin 30 to the chassis. Computer pin 30 uses a Lt blue/yellow wire. Remove the passenger side kick panel and then remove the plastic cover from the computer wiring connector. Use a safety pin to probe the connector from the rear. Jumper the safety pin to the ground near the computer.
Be sure to remove the jumper BEFORE attempting to drive the car!!!

So what thats basically saying is that the sensor on the top front of the T5 is not a neutral switch as far as the computer is concerned.

Ok, I only scanned over what you posted. Next time I have a T5 apart I'll take a closer look at the switch.
