Hello,

Just finishing up a S5 JDM into S4 NA swap and a I have two hoses that I can't seem to figure out where they go.

Here is the first one:





Here is the second one (this one was blocked off when we got it):



Any help is greatly appreciated! Thanks!

 

If you like brakes - you'll find a way to hook those first two lines together. The rubber hose likely conects to your brake boster if you trace it.

The other hose that is blocked off - looks like it disappears under the UIM and is likely a spare vacuum source.

 

first pic is of your brake booster line. The Jspecs had them in that spot.

 

Yep, that first plug you can just plug it and go on. You don't have to have anything hooked up to it. It was the brake booster line for JDM cars and right hand drive cars.
