My gauge has a white wire instead of a yellow wire. Can I use the white wire in its place?Updated 2 hours ago

Not necessarily. Some GlowShift gauges, including the MaxTow and Elite 10 Color Series, use different wire colors than other gauge series.

For these gauges, the white wire is the switched 12V power source, while the red wire is the constant 12V power source. The switched power turns the gauge on with the vehicle, while the constant power allows features such as color memory to retain their settings.
