Default 1990 5.3 V-12 Vacuum line Schematic Availability

I have just about everything reconnected after reinstalling the engine. I am having trouble with routing of the vacuum lines. I looked in the reprint of the service manual and the Repair Operation Manual AKM 3455, but can't seem to find a vacuum line schematic. Any suggestions?

Did you look at the underside of the hood? That's where they are normally.
Also, try here:

Thanks jal1234. I did not find the decal under my hood, but my car was repainted a few years ago and might have been removed. I opened the attachment link you sent and opened the decal in the table there and was able to print it out. There are apparently different routing schematics for different years.

It seems like there are a ton of vacs, spaghetti like, but many of the folks here are all too (painfully) familiar. Of ya post a picture, question or need or two, you're bound to get an answer. Maybe even some ideas to eliminate some of the messy-ness. Jus say'n

There are MANY routing schemes. Jaguar was constantly adding primarily emissions related bandaids to the vacuum system. When the HE can out, there was a significant change, another when the Marelli distributor replaced the Lucas, and more changes with the 6.0. Even my 85 and 87, both HEs, are different.
