The kit ships complete with a 1/8-27 NPT temperature sender, a 2-foot harness, mounting bracket and hardware, plus a visor and step-by-step instructions to streamline installation.

How accurately does the gauge read coolant temperature?

The GlowShift gauge covers a practical operating range from 100° to 300°F, suitable for street, towing and many light-performance applications. Readings come from the included 1/8-27 NPT temperature sensor and are shown on a calibrated dial with a visible red pointer.

What lighting and styling options does the kit offer?

A dimmer wire connects to the headlight circuit to reduce brightness by about 30% when headlights are on, keeping the display comfortable for night driving.
