vacuum line

I have an 86 truck with a Z24i motor. I recently failed a smog check. The smog tech told me that my lines are either plugged or misrouted. I had replaced some old lines that connect on the front of the air cleaner. There are four lines that connect there and have colored stripes on them, obviously the new lines no longer have the colored stripes, and I think I may have gotten them mixed up. The Nissan dealers only schematic couldn't be deciphered even by their own headmechanic. I have less than ten days to fix this or I have to repay. Can anyone help?
