Step 7: Find a suitable location to mount the device

Find a suitable location to mount the device. Suggested mounting locations are shown below.

Behind the driver’s side knee panel (A)
Behind the instrument cluster (B)
Behind the center console (C)
Behind the glove box (D)

Consider the following when choosing the mounting location:

• Network coverage at the mounting location:
  • The device should be mounted label-side up and skyward-facing.
  • The device should not be mounted directly under large metal parts.
    The device will work through glass, plastic and composites.
• Space at the mounting location:
  • There should be ample space for you to secure the device firmly with zip ties.
  • The mounted device must not obstruct the operation of the vehicle.
• Possibility of damage to the device or cables:
  • Avoid heat sources (for example, a heating vent or duct).
  • Avoid sharp surfaces.

Step 8: Make the 3-wire connections

1. Familiarize yourself with approved methods for making 3-wire connections:
   For information about butt connectors, posi-tap and add-a-circuit fuse block adapters: see Verizon Connect Installation and electrical connection policy guidance.
   For information about poke-and-wrap: see FAQ: How to make a poke and wrap connection (solderless splice)
   The image below shows a connection made using the poke-and-wrap method.
   
2. On the harness, identify the wires for 3-wire power. 
   
   (D1) Black wire (connects to ground)
   (D2) Red wire (connects to power)
   (D3) White wire (connects to ignition)
3. Connect the red wire to a constant power (batt+) source.
4. Connect the white wire to a true ignition source such as the ignition switch, factory spare wire connectors labeled for such use, or the fuse box.
   Use a digital multimeter to verify the voltage doesn't drop below 9 VDC while the engine is cranking.
5. Connect the black wire to ground.
   On light-duty vehicles, terminate the ground wire to the chassis using a ring terminal and self-tapping screw, a factory-marked grounding bolt, or a factory-marked spare wire labeled for such use.
   
   On heavy-duty vehicles, connect the ground wire to a factory-marked spare ground wire or grounding point labeled for such use.
   On heavy-duty vehicles do not make a chassis ground using a ring terminal and self-tapping screw. Recent models typically have the chassis and frame separated, and this can cause electrical issues for a chassis ground.

Step 9: Connect the harness to the device

Plug the 24-pin harness connector into the CalAmp LMU-36xx device.

Step 10: Connect optional peripherals

This step is only for installations that have optional peripherals or sensor inputs.

Peripherals that can be monitored using sensor input connections include PTOs, booms, brooms and plows.

1. On the harness, identify the connectors for optional peripherals.
   
   (C1) Serial 2 connector plug
   (C2) LED connector plug (see Canadian ELD Compliance Solution for Fleet Installation Guide)
   (C3) Switch LED connector plug
   (C4) Serial 1 connector plug (connects to Garmin)
   (C5) 1-Bit bus connector (connects to Driver ID reader or Temperature Sensor)
   (C6) Driver ID buzzer connector plug (use with Canadian ELD dongle for indicator light)
2. Plug the 24-pin connector into the CalAmp LMU-36xx device.
3. Connect the peripherals harness to the corresponding Molex connector.
   Refer to the following guides as relevant along with the Sensor inputs section below:
   Installation guide: Driver ID (Reveal and Fleet)
   Technician guide: Temperature probe on Fleet (Fleet only)
   Technician guide: Magnetic door sensor (Fleet only)

Sensor inputs

Inputs require a minimum voltage transition of ±6 volts up to 30 volts maximum.
Inputs should switch between negative and positive, or negative and open polarity unless otherwise directed. A 5 pin SPDT relay may be required for sensor input installation.

1. On the harness, identify the wires for sensor inputs.
   
   (E1) Blue wire
   (E2) Blue/orange wire
   (E3) Purple wire
   (E4) Gray wire
   (E5) Pink wire
2. On the 24-pin connector (A), identify the pins for the sensor inputs.
   
   (A1) Input 1: Pin 1 (blue wire), Reveal: positive (+) trigger, Fleet: negative (-) trigger, connects to PTO when applicable         
   (A2) Input 2: Pin 2 (blue/orange wire), negative (-) trigger (connects to boom when applicable)
   (A3) Input 3: Pin 3 (purple wire), negative (-) trigger
   (A4) Input 4: Pin 4 (gray wire), negative (-) trigger
   (A5) Input 5: Pin 5 (pink wire), negative (-) trigger
   (A6) Input 6: Pin 6 (black/red wire), negative (-) trigger [goes to the Switch LED Molex connector]

Inputs do not require the 3 wire leads to be installed.

For more details, see CalAmp 36xx I/O Accessory Harness descriptions and wiring diagram.

Step 11: Use the LED lights to identify the device status

1. Start the vehicle and use the LED lights to identify device status.
2. Refer to CalAmp 36xx - Reveal and Fleet LED indicator light patterns for further details.
   The LED light patterns are different for Reveal and Fleet installations.

Step 12: Route the cables and secure the device

1. Put the device in place at the mounting location.
2. Fasten the device securely to a stable mounting bracket or wire bundle using zip ties.
   You can pass the zip ties through the fastening tabs on the sides of the device.
   You must fasten the device securely so it cannot move around. If the device is not secure, the accuracy of harsh driving event reporting will be reduced.
3. Route the cables to the mounting location.
   Coil and secure any loose cabling using zip ties to ensure it will not interfere with the driver or normal operation of the vehicle.
   
4. Check everything is fastened tightly, and trim zip ties if they have excess length.
   Use extreme caution when trimming the zip ties. Accidentally cutting or nicking nearby vehicle wires will cause performance issues with the vehicle.

Check the installation does not interfere with the driver or normal operation of the vehicle.
If you have removed the dash panel, do not replace it until the network connection is confirmed
(see Step 13).
