Explain the data for the plan:1: Leaving Open 2: Under Pressure 3: Dumpvalve Yellow: Accelerator Pedal Sensor Red: 12V Ignition Switch Black: Ground, Car Body Blue: Vacuum Pump White: Vacuum Pump How to measure this:Set the at good value and switch the ignition on. Connect the black wire to the ground and the red wire to the throttle pedal sensor on the steel wire. When you have the appropriate wire, you measure 0 to 5 volts. be careful! When you press the accelerator pedal sensor manually, the meter must provide a variable voltage. Function:When the turbine operates, it generates extremely high pressure inside. Although the turbine itself has an aperture for releasing high-pressure gas, it still appears to be somewhat inadequate when facing continuous turbocharging conditions. By using a pressure relief valve, high-pressure gas can be quickly released to facilitate turbocharging action. Installation instructions:The large opening and intercooler between the installed dummy valve and the intake manifold. You need to drill a hole in the entrance pipe, and then you must attach the connector. This dump valve is installed on the connector by using a hose, or you can directly connect it to the dump valve connector. that the connection seal uses ring connectors. Open the dummy valve and pull it up, making the spring stronger than if you had to mount a metal washer on the dummy valve. be careful! The yellow wire connected to the accelerator pedal sensor must not have a higher voltage of 5 volts at . This is when the pedal is fully depressed.
