Yes, for whatever reason you seem to have the "starts in any gear" problem only when the NSS wiring connector is attached to the NSS. That makes the NSS suspect but you reported ohm readings which indicate the NSS is working properly. Cannot have both conditions. Still possible that the readings for the NSS testing are wrong and the NS or the Internal Comb are still a problem. You need to start over and tell us exactly what you tested and what meter you are using, digital or analog.
Fill out this chart.
With NSS connector not connected to the NSS:
In PARK - measure resistance of the center NSS pin to the body of the transmission. ______Ω Should be close to Zero Ω. Flashing or OL is OPEN or very high resistance.
In REVERSE - same measurement ______Ω Should be OPEN
In NEUTRAL - same measurement ______Ω Should be close to Zero Ω.
In Drive - same measurement ______Ω Should be OPEN
In 2nd - same measurement ______Ω Should be OPEN
In 1st - same measurement ______Ω Should be OPEN
It is almost impossible to have the wiring and the NSS check out as good and still start in any gear
