Wiring the AEM 30-4110

Before you start wiring the AEM 30-4110, it’s important to read the instructions carefully and familiarize yourself with the wiring diagram. You will need to gather the necessary tools and materials, including a wire crimper, electrical tape, and wire strippers.

Step 1: Mount the Gauge

The first step in wiring the AEM 30-4110 is to mount the gauge in a suitable location. You should choose a location that is easy to read and within easy reach. Once you have chosen a location, use the included mounting hardware to secure the gauge in place.

Step 2: Connect the Power and Ground Wires

Next, you will need to connect the power and ground wires. The power wire (red) should be connected to a switched 12V source. The ground wire (black) should be connected to a suitable ground point on your vehicle’s chassis.

Step 3: Connect the Analog Output Wires

If you plan to use the analog output feature, you will need to connect the analog output wires. The yellow wire is the signal wire, and it should be connected to the data logger or ECU. The brown wire is the ground wire and should be connected to a suitable ground point on your vehicle’s chassis.

Step 4: Connect the Sensor Wires

The final step is to connect the sensor wires. The AEM 30-4110 comes with a Bosch LSU 4.9 wideband sensor, which should be connected as follows:

Wire Color Function
Red Heater +12V
Yellow Heater Ground
White Signal Out
Black Sensor Ground

Connect the red wire to a switched 12V source, the yellow wire to a suitable ground point on your vehicle’s chassis, the white wire to the signal input on the AEM 30-4110, and the black wire to a suitable ground point on your vehicle’s chassis.
