94 4runner ADD 4wd not working

[4runnerBrett]

So I did a motor swap recently and after the motor swap the 4wd is not working (worked before the motor swap). As far as I can tell everything is plugged in electronically. And the actuator vaccuum tubes are plugged in. I switch into 4wd and the dash clicks but 4wd light does not come on.

Im curious on some things I could do to trouble shoot what the issue might be.

The ADD is vaccum actuated, so I would be checking that first.

Two things are needed for the dash indicator to light.
The t-case must be in 4Hi or 4Lo to close the first switch, and the front diff actuator must move to Lock position, which closes the second switch.

Got it fixed. I guess we had a couple vaccuum hoses in wrong spots.
