AutoMeter Wideband Extension Wiring Harness

25 Feet for Street and Analog Wideband AFR Gauges

Part #: 5252

Overview

The AutoMeter Wideband Extension Wiring Harness is a versatile accessory designed to extend the reach of your AutoMeter Street or Analog Wideband Air-Fuel Ratio (AFR) gauges. Measuring 25 feet in length, this harness provides the flexibility needed for custom installations, especially in vehicles with mid or rear engine configurations where the factory harness may not be long enough. Whether you're upgrading your existing setup or installing a new wideband gauge in a complex engine bay, this extension ensures a clean and reliable connection.

Ideal for automotive enthusiasts, tuners, and professional installers, this harness allows you to position your AFR gauge precisely where you need it without sacrificing signal integrity or ease of installation. It is especially useful in applications where the gauge needs to be mounted away from the engine bay, such as in the cabin or in custom dash setups. With this extension, you'll get a neat, professional-looking installation that maintains the accuracy and responsiveness of your wideband AFR readings.
