I've been doing some research (got an FSM

). Here's what I figure needs to be done:
Mechanically:
- add the counter shaft for 4L with it's bearings
- add the mating 4L gear on the output shaft
- change the fixed forks for the actuated forks
Electrically:
- add the 4WD module (don't know yet if the other computers need to be changed)
- the dash switch
- bits of harness under the truck
The funny thing is that the "one-mode" transer case actually has the center diff locker in it. There's just no way to activate it. The base case has two fixed forks, the diff locker and the reduction shift sleeve, just no 4L gearing. Meaning there may be a cheap way to at least add 4HI lock.
still working on it... my dealer's service manager looking into to it with Suzuki as well.
