Ok so to start, I have a 90 yj that had the 2.5L motor. It now has a Chevy 406 small block with a 700r4 transmission and an np231c transfer case. I am trying to figure out how to hook the vacuum lines for the 4wd to the gm transfer case. The hoses are already hooked up to the actuator on the axle. Had anybody ever done anything like this? Or does anybody know anything about how to do it?
