Wideband Power Harnesses
A wideband power harness supplies power and ground to a wideband air/fuel ratio gauge or controller. A wideband reading is only as useful as the wiring behind it. A dedicated harness keeps those connections tidy and consistent instead of relying on improvised splices. People fit one when adding a wideband gauge to monitor tuning or engine health, or when replacing a worn or damaged harness.
We currently have 1 wideband power harness in stock, from AEM. It is the AEM Power Harness for the X-Series Wideband Gauge, which is intended to pair with that AEM gauge.
Before you order, check a few things:
Confirm the harness matches the exact gauge or controller you own.
Plan where you will take switched power and a solid ground.
Route the wiring away from heat, moving parts and ignition components.
Check whether your setup needs any extra connectors or hardware.
