Vacuum scheme for 1988 xjs

Does enyone here can guide me step by step on where every vacuum line should go ?
I looked online but i found many schemes witch was different one from the other.

Hello Shahar - here are some vacuum line diagrams - the first two pictures are from the labels attached to the bonnet on my 1991 XJS V12 - the next three pictures are from my service manual for the 1983 to 1988 XJS V12 - hope one of these will help you -

once you determine which is the match for your 1988 XJS V12, would you please post here so that it will help others also - thanks, Tex.
