2.2 Plan The Installation
Verify Power, Ground and Ignition. Be sure to check each source (power, ground and
ignition) to ensure that the proper signaling exists. This is typically accomplished with a
multi-meter.
Before drilling any holes or running any wires, decide where each hardware component will
be located (LMU, antennas, peripherals, etc.). Be sure that the cables to the LMU are not
bent or constricted in any way. Also make sure that the LMU is kept free from direct
exposure to the elements (sun, heat, rain, moisture etc...).
Be advised that an installation that violates the environmental specifications of the LMU will
void the warranty.
The best way to ensure a trouble-free installation is to consider your options and make some
decisions before you start. Take a look at the vehicle and determine how to best install the
LMU for the following purposes:
 Accurate data gathering and simulation of how customers actually use your solution
 Ongoing monitoring and maintenance of LMU equipment
 Accidental or intentional alteration of the equipment or cable connections
The following sections cover some of the issues to consider when planning your LMU
installation.
2.2.1 Size and Placement of LMU Unit
The dimensions of the LMU should be taken into account, particularly when installing in a
vehicle:
Whether you intend to place the LMU under a seat or into a cavity behind the vehicle’s
interior molded trim, be sure the LMU will fit before drilling any holes or running cable
 Be certain that the cables running to the LMU will not be bent or constricted.
Damage to the cables may impede the LMU’s performance.
 Be certain that the installation point will not violate any of the LMU’s environmental
specification (temperature, moisture, etc…) as improper installation of the LMU may
void the warranty.
See the LMU Environmental Specifications for the exact measurements and specifications of
the LMU-4200™.
Typical installations will place the LMU under the vehicle dash board, or in the trunk. Make
sure you can get access to the unit afterwards as under some circumstances it may be
necessary to add additional wiring or connections to the LMU.
