We can ignore the part about the vacuum disconnect on the front axle, at least until someone swaps axle housings.

Well... I have the 2000 and 2001 Isuzu manual, it incudes Trooper and VX. I didn't check on the live TOD computers, but it looks like Trooper's TOD computer got an extra one connection for the switch, and it also got extra connections to send commands to the vaccum-electric devices (that are not installed on VX) to perform the disconnect...
