• I have a 1987 S4 Turbo II that I am deleting emissions on. When it comes to the switching actuator, do I keep the green solenoid on the rats nets? According to this diagram I do. Let me know what you think.

• Has anyone ever replaced the metal line from the switching actuator as shown in the picture below. Mine is rusted out. I dont think I can replace it with a regular vacuum line as its right by the turbo.

Last question, when installing an aftermarket boost gauge, where would I tee in the sensor? would it go behind the restrictor pill, as in my picture, or after? Maybe another place works better and I dont know! Give me the input!
