I think the first one is from someone previously running a boost gauge. (you dont need it)And the second just run a single vacuum line from the waste-gate to somewhere on your intercooler piping.

yeah the first one is for a boost gauge. which i recommend getting one. its good to be able to have this incase something goes wrong and overboost.you can cap the bottom one on tb.on the second tee, you can run straight to ic piping, this will be stock boost. you would keep it tee'd if you wanted to run a boost controller.

okay wait so none of these 2 hosesgo anywhere on this???

and if they dont then where does the one from the T fitting go to??? intercooler piping???

and where would the thicker looking one go to???

If you need to know where the stock lines go, I have the JMD S13 service manual picture translated and posted up in a thread linked from the SR FAQ.
