1. Disconnect the negative battery cable.
2. Connect the red wire to a positive 12 volt constant
(un-switched) source, either directly to the battery or
to a fuse panel on the vehicle.

If wiring to an un-fused source, install a 3
amp fuse inline within 20 inches of the sources
connection. You may obtain an optional
“expandable circuit” accessory. This
component easily fits into your fuse panel and
provides an additional fused power wire for
accessories such as gauges. This is available
at www.MaxTow.com or a local auto parts
store.
3. Connect the white 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 switch of
the vehicle.
4. (Optional) The dimming feature decreases the brightness of
the gauge face by 30%. Using automotive grade wiring (18
gauge), connect the orange wire to a positive 12 volt switched
source. The most common installation is to splice and connect
to the 12 volt positive headlight source.
5. Connect the black wire from the gauge to any good
(unpainted) ground connection. You may also route a wire
directly to the negative side of the vehicle’s battery.
6. Reconnect the negative battery cable.
