3' Quick-Lite Extension Wire

The AutoMeter 3' Quick-Lite Extension Wire (part number 3257) is an essential accessory for builders and technicians who demand reliable gauge illumination and signal integration in custom automotive applications. Whether you're installing a full digital dashboard cluster in a classic hot rod, retrofitting modern gauges into a vintage platform, or extending gauge connections in a custom engine bay layout, this extension wire bridges the gap between your gauge housing and distant power or signal sources. Quick-Lite technology streamlines installation by eliminating the need for splicing or soldering, making it ideal for both professional shops and serious DIY mechanics tackling complex gauge setups.

This three-foot extension wire is engineered to maintain signal integrity over moderate distances without voltage drop or electromagnetic interference that could compromise gauge accuracy. The Quick-Lite connector system features a plug-and-play design that mates directly with AutoMeter gauge housings, eliminating connection failures caused by corroded pins or improper crimps. The lightweight construction (0.11 lbs) and compact packaging make it easy to route through tight engine bays and behind dash panels. The wire's robust insulation protects against heat cycling, oil exposure, and vibration—critical factors in high-performance and custom builds where thermal stress is inevitable.

Technicians working on late-model swap projects, engine conversions, and full gauge cluster installations will find this extension wire invaluable when factory harness lengths fall short. The three-foot length provides sufficient reach for most custom dash layouts and engine bay reconfigurations without excess coiling. This wire integrates seamlessly with AutoMeter's complete gauge lineup and works across electric, digital, and hybrid gauge systems. Installation is straightforward—connect the Quick-Lite terminals to your gauge, route the wire to your power or signal source, and secure with standard automotive clips or tie-downs. No special tools, no soldering, no guesswork—just reliable gauge operation in your custom build.
