I guys, i was performing the “nest” removal and when I start to reinstall the fuel system I noticed that unlike all the guides I have two different connections that go to the solenoid (PRC); I've searched everywhere and can't find anything like this (it's not even mentioned in the manual). what should I do? put a y and connect them both in intake or plug one or the other?
also i’m pretty shure that mine line goes to the green solenoid (I know that the s4 use it for twin scroll but mine is 91 s5 EU).

Thanks in advance
