Looking in Google, can't find anything in reference to replacing a Neutral switch inside the gearbox...
Tx for any tips
Sometimes a switch will get "fussy" and only light up when the selector is centered in neutral. But it sounds like this is not a single instance, but a total failure.
The neutral switch simply unscrews from the case. After you get it out, test the switch itself to see if the problem is the switch contact or the switch "button" not being pushed far enough.
If you clean enough chain lube out of there, you'll probably see clearly how to get it out.
