I'm putting a motor back in my step dads truck and he pulled everything apart and I can't figure out where the vaccum on top of the transfer case goes. I know it mounts to bell housing in the trans but what connects to it?

 

Sounds like your referring to the vent tube. It does'nt connect to anything, just bolt it to the upper part of bell housing.

 

there's a 3 way vacuum valve on top of the t-case. 2 lines go to the CAD and one to the engine bay where it hooks in with the other vac lines. there might even be a 4th line for a test port.

 

 

Thanks for that diagram. Where can I mount the 2 lines on the control switch that don't go to the cad?
