Wiring Harness Stepper Motor Press. Gauges

The Wiring Harness Stepper Motor Press Gauges from AutoMeter (SKU ATM5227) is a complete electrical harness assembly designed for full-sweep electric pressure gauges. This OEM-quality wiring harness eliminates guesswork during gauge installation by providing a pre-engineered connector solution that integrates the stepper motor mechanism with your vehicle's electrical system. Whether you're upgrading your instrument cluster, restoring a classic vehicle, or building a custom gauge setup, this harness ensures reliable signal transmission and precise gauge movement.

The stepper motor design allows the gauge needle to sweep smoothly across the full range of pressure readings in response to electrical pulses from your vehicle's engine control module or dedicated pressure sender. AutoMeter's engineered connectors are rated for automotive electrical environments, withstanding vibration, temperature fluctuations, and moisture exposure common under the hood. The compact harness assembly (measuring 5.7 x 0.8 x 7.7 inches and weighing just 0.17 lbs) routes easily behind dashboard panels without bulk, and the pre-assembled configuration reduces installation time while maintaining proper gauge calibration and response accuracy.

This wiring harness is ideal for enthusiasts installing AutoMeter full-sweep electric pressure gauges in street rods, performance builds, marine applications, or light-duty trucks. It's also essential for anyone replacing a damaged or aging harness in an existing gauge cluster. Proper installation requires connection to a quality pressure sender (sold separately) and a stable 12V power supply; consult your vehicle's wiring diagram or AutoMeter's installation guide for correct routing and grounding. For best results, use this harness with compatible AutoMeter gauges and automotive-grade electrical connections.
