Vacuum hose routing to transfer case ?

[sewerrat]

I have a salvaged 89 s10 4x4 4.3 tbi. I need help in the vacuum hose routing from the vac s/w at the transfer case. I see three hoses to that switch but is unsure where they are suppose to attach to. My haynes shows no vac. diagram and the sticker on the top rad support is gone. I'm guessing one to manifold source, one to the actuator, and the other I'm not sure. Can anyone help or suggest an online site for a diagram? Thanks for any replies.

You are correct, one to the actuator, one to the manifold (where it should connect into a 'T') and the last one is simply a breather to let the pressure equalize to atmospheric thus releasing the actuator. It usually (at least on my 93 and 94) connects to a breather cap located on the firewall. On the 93/94's it is near the heater fan motor..

Luck..

look for a thread called "the 4x4 vacuum thread" in the lifting it section, i did a write up on just that.
