where do all the vacuume lines go on an 88
hi guys , i did a dummy and didnt map where all the vacuum lines go on my 88 4.0 . , first off its fair game to abuse me .hehe . but secondly where do they all go there is this big plastic block that i guess is used to help route things . oh one last thing .is it ok to disable the egr valve setup . i live in an area that doesnt have to smog unless we sell the jeep . thanks for all your help . 
lastly it looks like there are 2 lines that should come out of the throttle body . i know one goes the the map sensor but where is number 2 go .
