Wideband Sensor Harnesses
A wideband sensor harness is the wiring link between a wideband oxygen sensor in the exhaust and the gauge that reads it. A wideband setup reports air/fuel ratio across a broad range. That helps when tuning, when keeping an eye on a modified engine, or when checking for lean conditions under load. Harnesses can be damaged by heat, by contact with moving parts or by general wear. A clean, correct connection matters for a steady reading. Most people replace one after damage or when rerouting the sensor wiring.
We currently have 2 wideband sensor harnesses in stock, both from AEM. They are the AEM Sensor Harness for the 30-0300 X-Series Wideband Gauge and the AEM Replacement Sensor Harness for the Digital Wideband Gauge (30-4110).
Match the harness to your exact gauge part number, since connectors can differ between gauge models.
Make sure the harness can reach from the sensor to the gauge along your planned route.
Route the wiring away from exhaust heat and moving parts.
Inspect the sensor connector too, because a worn plug can look like a harness fault.
Confirm your gauge model, then pick your vehicle to see what fits.
