GMC Repair: 93 k2500 4x4 Suburban 454 - California, vacuum leaks, california emissions

Question
In order to smog the Suburban, we need to repair any vacuum leaks, and there is a small line that broke off.  We can find one end at the base of the air filter but cannot find where the other end connect.  We have also noticed two other lines unconnected.  Please advise us on access to a vacuum diagram.  Cannot find this info in my owners manual and please don't suggest the Dealer, been there done that.

Answer
Personally, every GM vehicle I have owned with California emissions, I have removed. As for the disconnected lines, I need you to take a photo and email to me: marvin.saunders69@yahoo.com The missing line on the bottom of the air cleaner is more than likely the heat advance. Is the missing line 2"-2.50"? Usually the California emissions will be routed to the exhaust. If you have any further questions, please email me directly. You should also look for a valve/expansion valve at the rear of the motor. From there it should go down and go into the catylist.
