I noticed that there are three (I think) nipples coming off of the UIM facing the passenger side fender that have nothing going to them on my car. Can anyone tell me what they are supposed to be hooked up to? Thanks in advance.

Largest one (closest to the firewall) = Brake booster vacuum line

The two smaller ones can either be capped or used for the following:

1. BOV (ABV)
2. Boost gauge

 

Damn, beat me to it!

 

Mahjik: beat me to it!

 

Many thanks. I thought all three looked pretty small, but I will double check when I get home and have access to the car.

Are you sure that you mean UIM instead of the LIM? Are you still using the stock twinns?

 

Sorry. I think you are right. It is actually the LIM. I thought that the UIM extended a little lower than it does. I'll double check when I get home, but looking at the FSM, I'm thinking it is on the LIM. I am running a single.

If it is in dead the the LIM. There are 4 tubes that extend through the manifold, They are not vacuum sources. They are not used if you are single turbo.

If that's the case, then you're fine. They're just pass-throughs for emissions components. If you're running a single setup, then most likely they're not being used.

 

Chris, if you're going to keep posting, how about you update this debacle of a thread?

Double checked when I got home it was definitely the four pass-throughs for emissions stuff on the LIM. Thanks for the help.
