Hey Guys, Okay so i feel like a complete Amature.
On my '91 Blazer S-10 i had taken off a bunch of vacuum lines so that i would be working in less of a tangled mess but now i have a problem. I havnt added any lines or removed any but i am missing one for my 4wd actuator under the battery...can some one tell me where this line starts? thanks.

 

Goes from the transfer case vacuum switch to the front axle actuator.

 

There is no T-Shapped line splitter at all in between? or Does it go strait throught? Im asking because from some things i have read there is. Is that only for the Supply Line to the transfercase?

 

There are no 'T's between the front axle actuator and the vacuum switch on the transfer case.

Search around a bit and you'll find the diagram applicable to the NV231/NV233 transfer case. Something like "NV233+vacuum" (without the quotes) will likely turn up the proper posts.
