ConneCTion poinTs
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 bat-
tery and fused as close to the battery as possible. Avoid
using a cigarette lighter or “Power Point” receptacles
as power sources. Mentor does not recommend wir-
ing power directly to a vehicle kill switch because the
Ranger will not power down correctly. Appropriate fuses
are provided 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 supply 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. Con-
necting 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 igni-
tion. If neither of these options are possible, then contact
your Mentor project manager and alternate ignition op-
tions can be discussed and approved.
