AEM Sensor Harness for X-Series Wideband Gauge 30-0300/30-0334 - Universal
AEM builds its X-Series gauge range around solid, repairable wiring rather than sealed throwaway looms, and this replacement sensor harness is part of that approach. It connects the wideband oxygen sensor to the gauge body on both the 30-0300 and 30-0334 X-Series wideband gauges, giving you a genuine AEM fix when a harness is damaged, chafed, or simply needs replacing after an engine bay rebuild.
This listing covers the sensor side wiring harness for the AEM X-Series Wideband UEGO Gauge, compatible with part numbers 30-0300 and 30-0334. As a universal component it isn't vehicle specific, so it suits any application already running one of these two gauges.
