I have an 89 Jeep Cherokee 4x4 with the 4.0 six cyclinder. The vaccum lines are messed up on it becasue someone(not naming names) decided just to rig everything if it broke

. Now the whole vaccum system is messed up and not workin correctly. So my question is does anyone have a diagram of all the vaccum lines, ports, etc that i can hopefully look at it n hook all my lines back up correctly.
Thanks, Wayne
