HOW TO USE:
- Mount the Gauge: Locate a suitable 2 1/16″ (52mm) gauge pod or mounting location in your vehicle. Secure the gauge using the included mounting ring.
- Install the Pressure Sensor: Identify a suitable location on your engine’s intake manifold to install the pressure sensor. Ensure the sensor is mounted securely.
- Connect the Vacuum/Boost Hose: Attach one end of the provided boost/vac hose to the pressure sensor and the other end to a vacuum/boost source on the intake manifold. Ensure a tight and secure connection to prevent leaks.
- Connect the Wiring Harness: Connect the 3-wire cable from the pressure sensor to the corresponding terminals on the back of the gauge.
- Connect the Power and Lighting Harness: Connect the power and lighting harness to a suitable power source in your vehicle (typically a switched 12V source and a ground). If your gauge has backlighting, connect the appropriate wire to your vehicle’s lighting circuit if desired.
- Verify Connections: Double-check all hose and wiring connections to ensure they are secure and correct.
- Start Your Vehicle: Turn on your vehicle’s engine and observe the gauge readings to ensure proper operation. The gauge should display the current vacuum or boost level.
