The three lines on the top of it how do I route them?
Do they get vacuum? does one and not others?
I see one ts of goes to the engine bay wheres it go ?
How does the vacuum engage the 4x4?
One goes to a vent, one goes to the actuator under or near your battery and the other goes to your TBI or equivalent to draw the vacuum. When you engage 4x4 the vacuum pulls a cable from the actuator and engages the front diff.
I'm not sure which lines are which though on the transfer case. There's a picture with arrows showing what each line does in the Liftin' It section. Search for "The 4x4 vacuum thread"
I think i found all i need , I didnt know where they went .
I knew I shouldnt thrown that vac ball out when I did that motor swap. I have to get one from a u pull it now.
