2.1Planning the Installation
The XTL 1500 radio operates only in negative ground electrical systems. Before starting the radio
installation, make sure that the ground polarity of the vehicle is correct. Accidentally reversing the
polarity will not damage the radio, but will cause the cable fuses to blow.
Planning is the key to fast, easy radio installation. Before starting the installation, inspect the vehicle
and determine how and where you intend to mount the antenna, radio, and accessories. Plan wire
and cable runs to provide maximum protection from inching, crushing, and overheating.
CAUTIONBefore installing any electrical equipment, check the vehicle manufacturer’s user manual.
The installation of this device should be completed by an authorized servicer or installer.

2-8Standard Configurations: Ignition Sense Cable
2.4Ignition Sense Cable
Motorola supplies an ignition sense cable and recommends that it be used with every mobile
installation. The ignition sense cable allows the radio to be turned on and off with the vehicle ignition
switch, and allows the radio to “remember” the state of the radio on/off switch, even if it is changed
while the vehicle is off.
Note that this feature can be turned on/off via Motorola CPS software.
• Always connect the red ignition cable (orange for remote) to “ignition” at the fuse block.
Note that for remote mount installations, the green and orange leads are connected, not the red lead
from the rear of the radio.
The ignition sense cable uses either a 3-amp (P/N 6580283E01) or 4-amp (P/N 6580283E02) fuse.
For other considerations when connecting the ignition cable, see the XTL 1500 Basic Service
Manual (Motorola publication part number 6815853H01).
2.5Antenna Installation
IMPORTANT NOTE: To assure optimum performance and compliance with RF Energy Safety
standards, these antenna installation guidelines and instructions are
limited to metal-body vehicles with appropriate ground planes and take
into account the potential exposure of back seat passengers and
bystanders outside the vehicle.
NOTE: For mobile radios with rated power of 7 watts or less, the only installation restrictions are to
use only Motorola approved antennas and install the antenna externally on metal body
vehicles. For mobile radios with rated power greater than 7 Watts, always adhere to all the
guidelines and restrictions in section 2.5.1 below.
2.5.1Selecting an Antenna Site/Location on a Metal Body Vehicle
1.External installation – Check the requirements of the antenna supplier and install the
vehicle antenna external to a metal body vehicle in accordance with those requirements.
2.Roof top – For optimum performance and compliance with RF Energy Safety standards,
mount the antenna in the center area of the roof.
3.Trunk lid – On some vehicles with clearly defined, flat trunk lids, the antennas of some radio
models (see restrictions below) can also be mounted on the center area of the trunk lid. For
vehicles without clearly defined, flat trunk lids (such as hatchback autos, sport uitility vehicles,
and pick-up trucks), mount the antenna in the center area of the roof.
Before installing an antenna on the trunk lid,
- Be sure that the distance from the antenna location on the trunk lid will be at least 85 cm
(33 inches) from the front surface of the rear seat-back to assure compliance with RF
Energy Safety standards.
- Ensure that the trunk lid is grounded by connecting grounding straps between the trunk lid
and the vehicle chassis.
IF THESE CONDITIONS CANNOT BE SATISFIED, THEN MOUNT THE ANTENNA ON
THE ROOF TOP!

Page 27
Standard Configurations: Antenna Installation2-9
4.Mounting restrictions for certain radio models
For 40 Watt UHF models, the 1/4 wave antenna
should be mounted only in the center
area of the roof, not on the trunk lid, to assure compliance with RF Energy Safety
standards.
5.Ensure that the antenna cable can be easily routed to the radio. Route the antenna cable as
far away as possible from any vehicle electronic control units and associated wiring.
6.Check the antenna location for any electrical interference.
7.Ensure that any other mobile radio antenna on this vehicle is at least one foot (30.48 cm)
away from this antenna.
NOTE: Any two metal pieces rubbing against each other (such as seat springs, shift levers,
trunk and hood lids, exhaust pipes, etc.) in close proximity to the antenna can cause
severe receiver interference.
2.5.2Mini-UHF Connection
To ensure a secure connection of an antenna cable's mini-UHF plug to a radio's mini-UHF jack, their
interlocking features must be properly engaged. If they are not properly engaged, the system will
loosen. Using a tool (pliers or wrench) will not overcome a poor engagement, and is not
recommended.
NOTE: Applying excessive force with a tool can cause damage to the antenna or the connector (e.g.,
stripping threads, deforming the collar or connector, or causing the connector to twist in the
housing opening and break).
The mini-UHF connector tool (Motorola part number HLN6695_) is designed to securely tighten the
antenna plug–radio jack connection without damaging either the plug or the jack.
Motorola recommends the following sequence to ensure proper attachment of the system (see
Figure 2-10):

Page 28
2-10Standard Configurations: Antenna Installation
1.Make sure that there is sufficient slack in the antenna cable.
2.Make sure that the collar of the antenna cable plug is loose and does not bind.
3.Make sure that the mini-UHF jack is tight in the radio housing.
4.Slide the collar back against the flange. Insert the antenna cable plug’s pin fully into the radio
jack, but do not engage the threads.
5.Ensure that the plug’s and jack’s interlocking features are fully seated. Check this by grasping
the crimp on the cable jack, rotating the cable, and noting any movement. If the features are
seated correctly, there should be NO movement.
6.Finger-tighten the antenna cable plug’s collar onto the radio’s jack.
7.Give a final tug, by hand, to the collar, and retighten by hand as firmly as possible.
8.Slip the mini-UHF connector tool over the coaxial cable, using the gap between the tool’s legs
(see Figure 2-11). Then, slide the tool up onto the plug’s knurled collar. Squeeze the two
straight legs of the tool firmly together between your thumb and index finger and turn
clockwise (as shown) to tighten the collar. It should take 1/4 turn or less. When you feel the
tool slipping on the collar, the connection has been properly tightened. The tool can also be
used to loosen a tight collar.
NOTE: DO NOT use pliers or any other device to grip the tightening tool. It has been designed to
allow you to achieve the proper torque on the collar without overtightening. Overtightening the

3.1VIP Overview
The vehicle interface port (VIP) allows the control head to operate outside circuits and to receive
inputs from outside the control head. There are three VIP outputs which are used for relay control.
There are also three VIP inputs which accept inputs from switches.
3.1.1VIP Output Connections
The VIP output pins are on the back or the rear of the accessory panel (J2). The pin information is
shown in Figure 3-6. Use these connections to wire control relays. One end of the relay should
connect to switched B+ voltage, while the other side connects to a software controlled ON/OFF
switch inside the control head. The relay can be normally on or normally off depending on the
configuration of the VIP outputs. There are two VIP output connections, as follows:
Table 3-1. VIP Output Connections
J2
VIP Number
12418
22419
The function of these VIP outputs can be field programmed in the control head. Typical applications
for VIP outputs are external horn/lights alarm and horn ring transfer relay control. For further
information on VIP outputs, see the control head programming manual.
CAUTION: XTL 1500 radios equipped with the following features
!
C a u t i o n
are capable of transmitting automatically, even if the radio is turned
off:
All XTL 1500 have accessory connector pins 14 and 15 connected
together to allow the radio to power down. Opening this connection
by REMOVING the accessory connector, or otherwise failing to
maintain a normally closed path, could, if left unchecked, drain the
vehicle battery, and possibly cause transmissions to occur.

3.3.1Installation into the Vehicle
CAUTIONBefore installing any electrical equipment, check the vehicle manufacturer’s
user manual.
The installation of this device should be completed by an authorized servicer
or installer.
1.Disconnect the negative terminal from the vehicle’s battery. Make sure that the battery cable
is secured such that it will not power the vehicle’s electrical system.
2.Place the accessory connector assembly in the approximate location for the permanent
installation of the radio. Allocate a sufficient service loop for ease of removing and servicing
the radio.
3.Route the ignition wire to either an ignition switch circuit or a power source that is always hot
(see Section 2.4 on page 2-8). In either case, verify that the source will be capable of
withstanding a load of 4 amps (see the wiring diagrams in the vehicle manufacturer’s service
manual). Always use the supplied fuse holder to prevent damage to the radio.
4.Secure wires with tie straps or electrical tape to prevent damage to or entanglement of the
wire. If wires are passed through drilled holes through firewalls or through any other metal
panels within the vehicle, the holes must be fitted with a rubber grommet (not supplied) to
prevent shaving of the wire’s protective jacket, which could cause electrical shorting.
NOTE: If the speaker pigtail is connected to the speaker assembly (optional), Be sure not to route the
speaker pigtail or wires through any areas that could cause potential damage to them. The
audio system is a floating ground; therefore, any speaker lines that come into contact with the
ground can cause damage to the radio. Check all wires for electrical shorts; properly repair
any electrical shorting issues immediately.
5.If there are no issues, reconnect the battery. Follow the vehicle manufacturer’s instructions
for the proper procedure.
3.3.2Installation onto the Radio
The accessory connector assembly is fastened to the back of the radio by jackscrews. The radio
should be fully mounted and secured in its trunnion prior to connecting the accessory connector
assembly to the radio. Be sure when connecting the accessory connector assembly to the radio that
there are no foreign materials in the mating surfaces. Do not force the connector on. It should slide
on with very little resistance. Be sure that both jackscrews are engaged in their threaded holes
before tightening them. Finger tighten the jackscrews securely to prevent loosening.
