Does your Neon SRT-4 have vacuum lines that are missing or cracked? The OEM vacuum harness performs a lot of important functions - It controls the wastegate actuator and blow off valve, and it relays pressure from the uppipe to the TIP Sensor.

This is also a great piece to consider if you simply want to refresh your car with some maintenance, as the plastic lines and rubber boots become brittle over time due to the heat in the engine bay. Once they become brittle, they can form cracks and leaks, and you'll lose boost pressure, and have faulty sensor readings.

      No, this is a oem part, and almost all Chrysler OEM parts do not come with instructions. If you want the vacuum harness diagram you can search around for it, we have it saved in our blog at as well.

    Are these the vacuums for the solenoids?

      Yes, this is the OEM vacuum harness for the solenoids that runs between the turbo and tip sensor, OEM diverter valve, and wastegate.

    If I have an aftermarket BOV how should the lines be run?

      If you want an aftermarket blow off valve on your 2003-2005 Dodge SRT-4, you will need a mounting pipe for it, and you'll run a new vacuum hose from the intake manifold after the throttle body directly to the blow off valve.

    If I have two lines that are cracked can I just replace those lines or will I have to replace them all at once?

      You could just replace them individually, these are bundled into one assembly however they can be separated from each other.

    Will this harness fit on the PT GT
    1 Answer
    • Customer Service Rep

      It seems it will not. Chrysler made a completely seperate vacuum harness for the turbo PT Cruiser. We believe the PT Cruiser turbo harness is now discontinued. However with that being said, if you needed a new harness we believe you'd be able to use this Neon SRT4 harness in a PT because its the same turbo and solenoids. The only difference is the placement of the harness and lines, which you could figure out where to route it. So we think it will work.
