knock sensor wire, where it go??
I assume you are talking about the little vacuum line that went to your air system, which you probably removed. You need to cap the tee that it used to pluginto at the back of the intake but the other remaining portion that goes to the passenger side does need to be attached to the intake or you won't be able to switch your heater vents off the floor.
The red electrical plug went to the solenoid that actuated the air system...assuming I interpreted your question correctly.
The other thing I am now getting lost on is the 2 places that hoses enter on top of the
Valve cover on passenger side. I've deleted air and e g r so does this have anything to do with this stuff
