I got rid of the double throttle solenoid so one of the nipples on the front of the UIM was unused.

I also eliminated the EGR solenoid so one of the nipples in the back is unused.

I didn't have any vacuum caps laying around so I decided to jump a hose from those two nipples. Is that ok? are those lines supposed to be pressurized?

The top nipple (in the line of 4) of the LIM also was no longer needed since it was for EGR. I also jumped that to the other side of the LIM to where the EGR was, into that nipple. Is this all ok? Im guessing i'm just keeping the whole vacuum system intact.

And a question of curiousity.
Do all the nipples on the UIM (the four upfront) all just open into the UIM? (no specific path internally) Same goes to the back nipples I jumped. Also the 4 nipples on the LIM rats nest side and the 4 nipples on the LIM ABS side.
So theoreotically I could've attached vacuum hoses to any of those nipples in no specific way?

Is this question too confusing?

 

What you did is fine. Those nipples all see the same thing (vac/boost)
