1. SPLICING
T-Taps are not a suitable form of splicing into existing cabling. All splices must be
soldered and glued. Heat shrink must be used for protection.
2. POWER
Power connections should be made directly to the battery and fused as close to the
battery as possible. Avoid using a cigarette lighter or “Power Point” receptacles as
power sources. Trapeze does not recommend wiring power directly to a vehicle kill
switch because the Ranger will not power down correctly. Appropriate fuses are pro-
vided with the installation equipment.
3. GROUND
The ground point should be that point where the (-) terminal from the battery is
connected to the body. This connection to the battery is typically a 6 or 8 AWG
black wire connected to the wheelhouse or radiator support.
Do not fuse the ground lead. If the ground-side fuse were to open, the entire sup-
ply current would be conducted by an alternate current return path, which may
cause the feed line to overheat possibly resulting in damage.
4. SWITCHED IGNITION POWER
It is important to utilize an unused ignition point. Connecting to an ignition point
that is currently being used to switch other devices can cause improper operation of
those devices.
There are two methods for interfacing to the vehicle ignition. If neither of these
options are possible, then contact your Trapeze representative and alternate ignition
options can be discussed and approved.

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 periph-
eral devices. Below is an example 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.
