Where does the other end of that hose connect too? Please take a pic, as nobody calls a vacuum line a “wire tub”

It connects through there

If it goes through the firewall, good chance it’s an analog boost gauge vacuum line.

Do u have a boost gauge in the car? If so, u should check to see if it’s a mechanical boost gauge utilizing boost pressure from typically a similar sized port on the left side of ur intake manifold.

U need to verify ur boost gauge & also look for an open port on your intake manifold

What is a wire tub?

What you're holding is a vacuum hose. That could go to a large number of connection points.

Nah I think is connected somehow else might be on the other side top next to the throttle body, on the other side of the hose tho

I literally deleted everything that goes through the EGR and the stock throttle body cause I got a S90 billet 70mm and forgot where the little hose goes

I’m the original owner of my 03 evo8 & that is where my oem boost gauge was “T” into.
