Preparation Steps
Before starting the installation, ensure your vehicle is parked on a flat surface and the engine is cool. Disconnect the battery to avoid any electrical issues during the installation.
Remove the Dashboard Panels
Begin by removing the dashboard panels to access the wiring. Use a screwdriver to carefully take off the panels without damaging any clips.
Locate the ECU
Find the Engine Control Unit (ECU) of your NSX, which is typically located under the passenger side dashboard. This is where you will connect the boost controller.
Wiring the Boost Controller
Once you have access to the ECU, it’s time to wire the Greddy Profec B Spec II. Follow the wiring diagram provided with your boost controller carefully.
Connect the Power and Ground Wires
Identify the power and ground wires from the boost controller. Connect the power wire to a switched 12V source and the ground wire to a suitable ground point. Use a multimeter to confirm the connections.
Connect the Signal Wires
Next, connect the signal wires from the boost controller to the ECU. This usually involves splicing into the appropriate wires that control the boost pressure. Refer to the wiring diagram for specific wire colors and locations.
Install the Boost Solenoid
Mount the boost solenoid in a suitable location under the hood. Ensure it is secure and away from any moving parts or excessive heat. Connect the solenoid to the boost controller using the provided hoses.
Finalizing the Installation
After all connections are made, double-check your work to ensure everything is secure and correctly wired. Reconnect the battery and turn on the ignition without starting the engine.
Test the System
With the ignition on, check the boost controller display to ensure it powers up correctly. Follow the user manual to configure the settings to your desired boost levels.
Reassemble the Dashboard
Once you have confirmed that the system is working properly, carefully reassemble the dashboard panels. Ensure all clips are secured, and the panels fit snugly.
