What are the Steps to Install the AEM X-Series Oil Pressure Gauge?

1. Prepare the Vehicle
2. Ensure the vehicle is parked on a level surface and the engine is cold.

3. Disconnect the battery to prevent any electrical shocks.

4. Install the Oil Pressure Sensor

5. Locate the oil galley plug on your engine. This is typically where the oil pressure sensor will be installed.
6. Use an adapter to fit the sensor into the oil galley plug. Ensure it is securely tightened.

7. If remote mounting, run the braided steel hose under the intake manifold and secure it with an Adel clamp to avoid engine vibrations.

8. Route the Wiring

9. Thread the wires from the sensor through the firewall and up to the dash. This can be the most challenging part, requiring patience and careful routing to avoid damage.

10. Use protective sleeving to prevent abrasion on the braided steel hose.

11. Connect the Wiring

12. Connect the sensor wires to the gauge wiring loom. The gauge kit usually includes a detailed wiring diagram, but here is a general outline:

    • Power: Connect to a fused power source using an add-a-fuse kit. Ensure the fuse is rated for the gauge’s power requirements (typically 5 amps).
    • Ground: Connect to a solid ground point on the vehicle.
    • Sensor: Connect the sensor wires to the corresponding inputs on the gauge.

13. Mount the Gauge

14. Choose a mounting location that is easily visible but does not obstruct the driver’s view. Common locations include gauge pods or dash mounts.

15. Secure the gauge using the mounting solution provided or purchased separately.

16. Calibration and Adjustments

17. The AEM X-Series gauge does not require calibration but offers programmable features such as peak/recall, standard or metric display, and threshold warnings. These can be adjusted using the buttons on the gauge face.
18. Ensure the gauge is set to the correct unit of measurement (PSI or BAR) and adjust the brightness as needed.

What are the Troubleshooting Tips for Installing the AEM X-Series Oil Pressure Gauge?

1. Wiring Issues
2. Double-check all connections to ensure they are secure and not causing any shorts or open circuits.

3. Use a multimeter to verify power and ground connections.

4. Sensor Placement

5. Ensure the sensor is securely installed in the oil galley plug and not subject to excessive engine vibrations.

6. Gauge Readings

7. If the gauge is not showing readings, check the sensor connection and ensure the gauge is powered correctly.
8. Consult the user manual for specific troubleshooting steps related to the X-Series gauge.
