99 xj Transmission and Transfer case swap into an 88 Comanche

[Southernmanche]

Hey there,

I was wondering if this

 

“1998-2001 require more work. All the transfer case input gear info from 1990.5-1997 applies, on top of that, the sensors have changed! You can either build the circuit given here by lawsoncl or swap the transmission tailhousing, sensor drive rotor, and output speed sensor as shown here by Frank Z to make this work.”

 

still applies if I swap a 99xj transmission (aw4) and transfer case (np231) into my 88. Any insight would be appreciated.

 

thanks
