Gauge Location
Pick a location in the dash for the fuel manage-
ment gauge. Make sure the gauge will not be
more than 10 inches from the speedometer if the
speedometer will be used for MPG calculation. A
sample gauge layout is illustrated.
In order for the Miles-per-gallon function of this
system to operate, it is necessary to connect the 4-
pin round connector of the management gauge to
the receiving connector of the new style multi-
function speedometer or GPS. They must be con-
nected to the same power source. The maximum
reach of these connector harnesses combined is
10 inches when speedo is used. No extensions
should be used, or the gauge can malfunction
because of electronic interference from radios
or other devices.
Gauge Installation
Install the instruments in the dashboard. If no
dashboard is available, install them in a place
protected from water spray.
WARNING
Disconnect the battery
installing or disconnecting electrical compo-
nents. Otherwise, you could be shocked or
an electrical short could cause a fire.
