For those that have bypassed their N249 valve.. what did you use to cap off the line from the valve?

and can you simply cap that line off? Or should I somehow route that line to the intake system?

Here is a diagram of the N249 valve and various lines feeding into it..

The whole reason for wanting to do this is to see if my DV or wastegate is staying open during some throttle applications..

Thing is my N112 valve gets some kind of signal from these lines.. so.. I can't cut the signal to those lines..
