4wd vacuum hose

Lost my 4wd and thinking has to do with hose to port? Can't find a diagram for assistance for my 1990 Wrangler.

Are you talking about the vac actuator? It's located on the passenger side and goes up the block and connects to a vac line by the passenger side firewall. If you want you can lock the actuator manually. Search the forum for '4wd actuator override' and you will find a ton of articles about how to do it.
