AEM 30-5133 User manual

Oil Pressure Display Gauges
Part numbers:
30-5133 - Analog Oil/Fuel SAE Pressure Gauge. 0-100psi
30-5135 - Analog Oil SAE Pressure Gauge. 0-150psi
AEM's Analog style Oil Pressure Gauges feature quick response and smooth needle movement that is
easy to read in all lighting conditions. AEM offers a 0-100 PSI oil pressure gauge and 0-150 PSI oil
pressure gauge. Each gauge offers a swept area of 320 degrees for the best viewing resolution at almost
any angle. A precision high-speed electronic stepper motor delivers lightning fast needle movement,
making AEM's SAE oil pressure gauge some of the fastest and most accurate gauges available. An
included sensor provides accurate pressure readings for each oil pressure gauge.
All AEM analog style gauges feature seven backlight colors that allow you to match your OEM or other
gauge backlighting, a silver and black bezel and a white and black faceplate to best match the interior of
your vehicle. The backlighting is adjustable via a dial on the rear of the gauge to optimize viewing in all
lighting conditions.
AEM Oil Pressure Gauges can quickly alert you to an engine damaging drop in oil pressure, allowing you
to protect your engine from damage.

INSTALLATION
1. Disconnect the negative battery cable.
2. Secure the gauge in a 2 1/16th” (52MM) mounting hole with the supplied bracket.
3. Plug the 8-wire power harness into the mating connector on the back of the
gauge and connect the wires as shown in Figure 1. Note: the locating tabs on
the side of the connector should be nearest the center of the gauge.
4. Thread the sensor into a suitable pressure port that has 1/8” NPT female
threads. Note: a small amount of thread sealant may be used.
5. Connect the sensor to the gauge using the 3-wire sensor cable. The single-row
connector connects to the back of the gauge. The locating tabs on the single-
row connector should be nearest the center of the gauge.
6. Reconnect the negative battery cable.
RED (Power)- Connect to a constant 12 volt power source utilizing a 5A fuse.
BLACK (Ground) –Connect to a clean power ground.
PINK (Switched Power) –Connect to a switched 12 volt power source utilizing a 5A
fuse.
GREY (Lighting Intensity) - Connect to instrument lighting circuit supply voltage.
*WHITE (Analog Output) - Connect to Analog + Input.
*BROWN (Analog Ground) - Connect to Analog –input. (Must be connected if Analog +
is used)
*optional –only needed if using the available differential analog output
Wiring notes:
RED - When wired as shown above, the gauge will park the needle against the
needle stop upon powering down. Alternatively, the RED wire can be connected to the
same location as the PINK wire. With the RED wire and the PINK wire connected to the
same switched power, the needle will remain at its current position upon powering
down. For both power connection methods, the needle will rotate to the parked position
before rotating to the value of the current operating condition upon powering up.
GREY –The GREY wire is used to control the lighting intensity of the gauge.
Maximum lighting intensity is achieved when the GREY wire is connected to 12 volts.
Minimum lighting intensity is achieved when the GREY wire is not connected. The
instrumentation illumination on many vehicles is controlled by varying the supply voltage
to the instrument panel lights. When the GREY wire is connected to the instrument
panel supply voltage, the intensity of the gauge is controlled by the dimmer switch on
the dash.
WHITE –The WHITE wire should be connected to the Analog + input on the
AEM EMS or the analog + input on a similar device.
BROWN –The BROWN wire should be connected to the Analog –input. If the
EMS or similar device does not have a –input, the BROWN wire should be connected
to a sensor ground. If no sensor ground is available, the BROWN wire should be
connected to a power ground. Note: The BROWN wire must be connected in order
to get correct readings from the analog output.

Changing the Bezel and Faceplate
The gauge kit comes with the black bezel and black faceplate installed. However, the
kit also comes with a silver bezel and multiple faceplates. Instructions on how to
change the faceplate are included in the kit on a separate sheet of paper. To change
the bezel, orient the gauge so you are looking at the faceplate. Rotate the bezel
counter-clockwise to unscrew it from the gauge cup. The bezel, lens, and rubber
spacer are all removable. Reassemble the gauge as shown below in Figure 3. Note:
When reassembling the gauge, it may be necessary to apply a light amount of pressure
on the lens and spacer to keep the faceplate from rotating when reinstalling the bezel.
Do not over tighten the bezel when reassembling the gauge.
Backlighting
The AEM Boost Gauge has 7 different backlight colors available to the end user, which
closely match some of the more common factory dash panels: white, blue, green, red,
orange, light blue, and aqua. To change the backlight color, rotate the backlighting
switch using a small precision style screwdriver. The backlight switch is accessed
through the small hole in the back of the gauge.

Status Lights
The AEM Pressure gauge has two status lights, see Figure 4. The status light on the
left will flash if an out of range low voltage sensor error is detected. The status light on
the right will flash if an out of range high voltage sensor error is detected. In either
case, the needle will point straight downward to signify an error. See Table 1 for
corrective actions.

Analog Output
The analog output from the AEM 100 PSI Pressure gauge is a linear dc voltage signal
that varies from 0.5 Vdc at 0 psig (0 Bar) to 4.5 Vdc at 100 psig (6.9 Bar) over the
operating range of the gauge. The signal is used for sending information to a data
logger or an engine management system like the AEM EMS or F/IC. The transfer
function for pressure units in PSI is listed below.
Pressure (psi) = 25 x Voltage –12.5
The transfer function for pressure units in bar is listed below.
Pressure (bar) = 1.73 x Voltage –0.86
