96 Tacoma transfer case

Guys quick question, I should be able to pull the transfer case without pulling the transmission correct? Also What are the two sensors on the transfer case one is missing a plug on the end the one closest to the rear of the transfer case.

 

Can only answer about the sensors; has to do with the vacuum actuator on an ADD system (4x4). Supplies a signal to the actuator to let it know that the transfer case is in 4x4 or 4x2.

Others will chime in with the rest though I'm sure a search will yield the results you need

*goes on a search*

 

Any idea exactly what it’s called I tried looking online but not having much luck.
