Vac diagram request from 95 Jimmy

Hi there,
Does anyone have a vac diagram for the 4.3L W series 95 Jimmy that shows the breakdown of parts/location for the transfer case vac switch and the vac
actuator under the battery tray, vac resevoir, check valves, etc? I have Haynes and Chiltons and they're useless for this. Maybe someone with access to GM's part program, MOD or All Data can help???
Thanks, A.
