ok evrything is hooked up and stuff is running almost perfect. i'm running back and cleaning stuff up. i noticed something. i dont have any of the lines for this hoook up(the stuff circled in black. all 3 lines are jsut laying over there. i was wondering what they do and what that switch circled in red does.
thx

 

plz forgive the gramatical errors, i'm white, what do you expect.

 

The thing in Red in the cruise control. It is activated by vacuum.

 

Nice avatar DF .

Sorry I cant help you 13B4Port. As DF said, the red is the cruise control servo, you could block off at least that vacuum line if youre not gonna run cruise.

anyone else? know what the stuff in black is?

 

Dont know if you can leave them out butthe ones circled in black go on the top of the LIM

 

The purple and green ones that is

 

wow, I didnt know the cruise control was controlled by vacuum on the s4.

 

Actually, the switch in red is not for the cruise control (although, that would be tapped into the vacuum line nearby). It's a switch that detects whether manifold vacuum is present or not and sends a signal to the ECU.
I believe the S4 equivalent is called a Pressure (Boost) Sensor, although it varies it's signal with vacuum and the -SE version is just a switch..

The two solenoids in black control the ACV.
