How to Install Mopar Oil Pressure Gauge - Digital Stepper Motor - White on your Ram

For Oil Pressure Gauge
1 - Sending Unit - 1⁄ 8" NPT
1 - Brass Adapter – 1⁄ 8" Female to 1⁄ 4" Male
1 - Wiring Harness

Contents:
2 - Aluminum Thumb Nuts
1 - Mounting Bracket
2 - Lock Washers
1 - Rubber Grommet

1. Check that you have all parts required for installation, and the  engine is cool.

2. Disconnect the negative (-) battery cable.

3. Gauge mounts in a 21⁄16” hole for 21⁄16” gauges, and a 25⁄8” hole for 25⁄8”  gauges. Use supplied brackets and nuts to secure gauge to dash.

4. Drill 1” diameter hole where wires pass through sheet metal  (such as firewall) and install rubber grommet provided.  (Grommet will require slit.)

5. Connect the white wire to dash lighting or switchable 12v light source,  the red wire to switched 12V source and the black wire to ground.  (see diagram for details)

6. For oil pressure gauge installation, an optional 1⁄4” NPT adapter is  included. If unit is to be installed on a high vibration application such as a  full race engine or engine capable of high RPM, it is strongly recommended  that the sender be remote mounted to either the fenderwell or firewall, to  insulate from vibration. Failure to remote-locate pressure senders on  such an application could result in gauge failure and potential  damage to vehicle and/or operator injury. Braided stainless steel lines  are sold separately by Auto Meter, and can be used to accomplish this.

7. Reconnect negative (-) battery cable.

NOTE: Test all fittings and hoses for any leakage. If any leaks are detected,  determine the cause of the leak and repair. Do not operate vehicle if  any leaks are detected.

The pointer will move backward to the stop pin and then move to the zero box. This procedure is an auto-calibration function and is performed on every power-up. While this test is being performed, the gauge may make a clicking sound. This is normal. 

To adjust the warning set point, momentarily press & release the WARN (W) button. The warning light will begin to flash and the pointer will move to the previous set point signifying that warning set mode has been selected. Once in set mode, press the WARN (W) button to move the pointer down, or press the PEAK (P) button to move the pointer up. Warning set points can only be set in the pressure range. Three seconds after the last button press, the warning light will stop blinking & the pointer will return to the current pressure reading. The warning set point is retained when power is removed  from the gauge. 

Press and hold the PEAK (P) button to recall the highest pressure reading since the memory was last cleared. To clear the memory, press & hold the PEAK (P) button, and while still holding the PEAK (P) button, press the WARN (W) button. The pointer will move to 0 psi to indicate that the memory has been cleared. Release the PEAK (P) & WARN (W) buttons to resume normal operation. The peak recall point is retained when power is removed from the gauge.
