Connecting the Power Wire Harness
2. To make the wiring of your gauges easier you can purchase
an expandable circuit. This component easily fits into your
fuse panel and provides an additional fused power wire for
accessories such as gauges. The expandable circuit is available
for purchase at www.GlowShift.com.
3. Using automotive grade wiring (18 gauge), connect the
yellow wire to a positive 12 volt constant (un-switched)
source either on the vehicle or in the fuse box.

Note: If you are connecting the yellow wire directly
to the battery, you MUST install a 3 amp fuse within
6-8 inches of the battery connection.
4. Using automotive grade wiring (18 gauge); connect the red
wire to a positive 12 volt ignition (switched) source. It may
be connected to the fuse panel, an accessory wire, or any
positive 12 volt source that turns on and off with the ignition.
5. Using automotive grade wiring (18 gauge); connect the
black wire to any good (unpainted) ground connection. You
may also route a wire directly to the negative side of the
vehicle’s battery.
6. The Night Time Dimming feature decreases the brightness
of the gauge face by 30%. Connect the orange wire to the 12
volt positive headlamp source. This allows the mode to be
activated when the headlights come on. This step is optional
and will not affect operation of the gauge if it is omitted.

Note: Do not connect the orange wire to a dimmer
wheel. This will cause the gauge lighting to flicker.
7. Reconnect the vehicle's negative battery cable.

If your gauge(s) do not illuminate or do not recall your
last saved color, your switched and un-switched
sources are reversed.

If your gauge(s) only illuminate red then the yellow
wire for constant source is not connected properly.

Be sure all of your wiring is correct to ensure proper
gauge operation.
