How to plug trans sensors on the KA24DE???

[s73]

Got a 92 240sx 5speed with a KA24DE, the transmission is leaking slowly at the sensors, not the speed sensor, but all the others (reverse light, 4th gear, 5th gear, and neutral). Its not leaking from the threads, but through the sensors it self. Seems to me the only solution is to buy new sensors, or remove and plug the sensor holes on the transmission.

Ok, I do want to keep the reverse light, so i will purchase a new reverse light sensor. Did some research and many have said that the other 3 sensors are really not needed (4th gear, 5th gear, and neutral sensors)

Here are my questions:

1)do anybody know the thread and pitch of the sensors? ( so i can find a bolt/plug to plug up the transmission), anybody know how long the bolts/plugs have to be?

2)Do I have to do anything to the wiring after I block off the transmission? (example: jump the wires at the pig tails….etc)

If anybody have done this before please provide me with some info, I cant seem to find it anywhere.

Thanks in advance.
