Wiring the AEM X Series Gauge

Wiring the AEM X Series Gauge is simple with the right tools and instructions. We have broken down the wiring process in steps to make the installation process more convenient for you:

Step 1: Mount the Wideband Sensor

Mount the Wideband sensor in a location that is easily accessible, but away from heat sources, such as the exhaust system. The sensor needs to be installed in a location that allows it to sample the exhaust. Avoid installing the sensor too close to the catalytic converter or muffler, as this can give false readings.

Step 2: Route the Wiring Harness

Route the wiring harness from the Wideband sensor to the gauge location. Make sure the wiring harness is away from moving parts or heat sources. Tuck wires under trim panels and secure with zip ties to ensure no wires are dangling.

Step 3: Connect Power and Ground

The AEM X Series Wideband Gauge requires a 12v power source and a ground wire. Connect the red wire to the 12v power source and the black wire to a good ground. Use a fuse inline with the 12v power source of at least 2 amps.

Step 4: Connect the Analog Output

The green wire on the AEM X Series gauge is for the analog output. Connect this wire to your data logger or ECU. The connection process may vary based on the manufacturer or ECU model, so ensure the data logger or ECU manual is readily available.

Step 5: Connect Serial Communications

Connect the grey and yellow wire of the AEM X Series gauge to your computer or other diagnostic equipment. This connection is for serial communication, and the process may vary based on the manufacturer or diagnostic tool model.
