vacum diagram 90 xj

i having a high idle problem and when i bougth it some of the vacum lines was disconected i want to see if any of you have the diagrams is a limited 90 6i is not on the engine i look for it and i cant find it

The common location for trouble in the vacuum lines is under the battery, where battery acid makes the lines brittle. Look for broken lines there. Also there is a vacuum ball in the front bumper, passenger side, that can crack.
There is a complete factory service manual for 1988 XJ on the web, but I have lost the link. The vacuum lines from 1988 to 1990 should be the same for XJs with the same engine/transmission/transfer case. HELP somebody- please post the link to help herreraxto!

thank you for your help, can someone post a picture of the vacuum lines that will help me a lot
