Install Guide

It is highly preferable to find an ignition source that goes high only
when the engine is actually on. If this source cannot be found, an
ignition source that goes high only when the ignition is in the ON
position is the next recommended source.
a) Auxiliary Electrical Panel (Preferred)
Many bus manufacturers will include an auxiliary electrical
panel for interfacing peripheral devices. Below is an ex-
ample of a common location in buses with a Ford chassis.
One of these terminals will typically be a switched ignition
point. A ring terminal should be used when connecting to
this type of ignition interface point. Ask the local mainte-
nance personnel if you need assistance to find this panel.
b) Fuse Panel
An unused ignition activated position in the fuse panel is
another option. This installation requires an Add-A-Circuit
fuse holder as pictured below. It is not acceptable to use a
āfuse sleeveā
