Technician guide: XT63xx with ECMD and 3-wire for light duty vehicles on Reveal

Leer en Español

This article explains how to install a Xirgo XT63xx device on light-duty vehicles with an ECMD cable and 3-wire power.

Time required: 20-40 minutes

Hardwired ignition requires a 3-wire install parameter file. If the device does not recognize ignition status, a parameter update may be required. (At Step 10, you will call Reveal Support for this.)

In this article:

• Step 1: Locate and capture the device serial number
• Step 2: Identify the device LEDs
• Step 3: Choose where to mount the device
• Step 4: Connect the ECMD cable
• Step 5: Connect the I/O harness
• Step 6: Install the Driver ID reader and external buzzer
• Step 7: Install the OBD-II diagnostic cable
• Step 8: Install the 3-wire connection
• Step 9: Route the cables and secure the device
• Step 10: Update the device configuration and verify operation

For installations that do not have a Driver ID reader and external buzzer, step 6 is not required.

Step 1: Locate and capture the device serial number

The device serial number is on the top of the device.

Capture the device serial number (you will need it later to verify the installation).

Step 2: Identify the device LEDs

1. Identify the location of the device LEDs.
   
2. Note the LED colors and statuses.

Amber LED (Cellular Network)

• OFF: No power to device
• Solid: Ignition is ON, cellular network is acquired
• Flashing: Ignition is OFF
• Fast Flashing: Ignition is ON; searching for cellular network

Blue LED (Bluetooth)

• OFF: Bluetooth is not connected
• Flashing: Bluetooth is connected

Green LED (GPS)

• OFF: Searching for satellites
• Flashing: Satellite count +1
  • The LED flashes once to indicate a GPS signal is acquired.
  • The LED continues flashing to indicate the number of satellites that are visible to the device.

Step 3: Choose where to mount the device

Find a suitable location for the device to be mounted, such as behind the instrument cluster or the knee panel.

• For best reception:
  • The device should be label-side up and skyward-facing.
  • The device should have a clear line of sight out of the vehicle.
  • The device should not be directly under metal.

The device will work through glass, plastic, and most composites.

• The mounting location should allow securing the device with zip ties, VHB tape, or Velcro.

Step 4: Connect the ECMD cable

Cable parts

Red: 14 pin ECMD connector plugs into the Xirgo device
Green: OBD-II bypass connector, connects to the factory OBD-II port
Orange: OBD-II replacement connector, mounts in place of the factory OBD-II port

Plug the 14 pin Molex connector on the ECMD cable into the device.

Step 5: Connect the I/O harness

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

1. Plug the 24 pin Molex I/O harness connector into the Xirgo device.
   
   
   If no optional peripherals are installed, go to Step 9: Route the cables and secure the device.
   Otherwise, go to point 2 below.
   
2. Connect the I/O harness to the optional inputs (see images below).

Wire colors may change, always verify the pin number.

A: Input 1 is pin 6; positive input B: input 2 is pin 7; (-) negative input

A: Garmin B: Panic/Privacy C: Driver ID Buzzer D: Driver ID Reader

Step 6: Install the Driver ID reader and external buzzer

This step is only for installations that have a Driver ID reader and external buzzer. Review the Driver ID installation guide for more detailed guidance.

1. Mount the Driver ID Reader in a location that is convenient for the driver to use, such as to the right of the steering column.
   Use consistent placement in each vehicle whenever possible.
2. Install the Driver ID reader by drilling a 3/8" (9.5mm) hole into a dash panel with at least 3/4" (19mm) minimum clearance depth behind the panel.
3. Remove the retaining washer from the back of the reader and feed the 2-pin harness through the hole. Then secure the reader in place by sliding the retaining washer back onto the harness until it is snug against the back of the panel.
4. Snap the 2-pin Driver ID connector into the Driver ID Reader cable head of the I/O harness, and secure the excess cabling using a zip tie.

Powering the external Driver ID buzzer

Snap the buzzer's 3-pin connector into the buzzer cable head on the I/O harness, and secure it using electrical tape or a zip tie. Be sure not to over tighten a zip tie, doing so can pull the pin connection loose.
Note: The external Driver ID buzzer receives power from the ignition source connection made in Step 8: Install the 3-wire connection.

Step 7: Install the OBD-II diagnostic cable

1. Remove the vehicle's OBD-II connector from its mount.
2. Plug the vehicle’s OBD-II port connector into the bypass connector portion of the diagnostic Y-cable to provide power and diagnostics data feed to the device.
   
3. Mount the replacement OBD-II port assembly into the vehicle’s OBD-II port location.
   

Step 8: Install the 3-wire connection

Using the 24-pin power harness, connect its constant, ignition and ground wires as follows:

Red wire - Constant power (battery +) source.
White wire - True ignition source (not accessory power) such as the ignition switch, a factory spare wire connector labeled for ignition supply, or ignition supply labeled on the fuse box.
Black wire - Ground to a factory-marked grounding bolt, spare wire, or splice pack labeled for such use.
Do not make your own chassis ground using a ring terminal and self-tapping screw in the cab of a heavy truck, doing so may cause electrical issues.

Late model heavy truck chassis are separated from the frame by rubber grommets to improve ride quality which results in no low resistance return path for current. Because of this, the return path current will flow through the truck's sensitive in-dash electronics, and eventually through an ECM, TCM or other sensitive modules which are also susceptible to electrical damage due to improper grounding.

The image below shows the Poke and Wrap splice technique. Refer to the Installation and electrical connection policy article for information about additional this or other approved methods.

1. Using a ring terminal, terminate the ground wire to the chassis using a self-tapping screw, a factory-marked grounding bolt or a spare wire connector labeled for such use.
   
   
   For installations on heavy trucks, semis or construction equipment: Do not attempt to make a chassis ground with a self-tapping screw and ring terminal. Always use a factory-marked grounding point or a circuit labeled for such use.

Step 9: Route the cables and secure the device

1. Route the cables to the mounting location you chose in Step 3.
   Coil and secure any loose cabling using zip ties to ensure it will not interfere with the driver or normal operation of the vehicle.
   
2. Mount the device in the chosen location (see Step 3), behind the driver's side instrument cluster, center console or knee panel areas, and secure it to a stable bracket or wire bundle so that it cannot move using zip ties, VHB tape, or industrial strength Velcro. Do not cover the ESN/Serial Number with two-sided tape, the label will peel and be unreadable when the tape is removed.
3. For best signal, mount the Xirgo label-side up with a skyward-facing view and clear line of sight out of the vehicle. Do not mount the Xirgo directly under large metal objects like a mounting plate which can degrade or block GPS signal.
   The device must be fastened securely to prevent it from moving and generating erroneous harsh driving event reporting.
   
4. Check everything is fastened tightly, and trim zip ties if they have excess length.
   Use caution when trimming the zip ties. Accidentally cutting or nicking nearby vehicle wires will cause performance issues with the vehicle. If you have removed the dash panel, do not replace it until the network connection is confirmed (see Step 10).

Step 10: Update the device configuration and verify operation

1. Call Reveal Support at 866.908.1165 to update the device configuration so ignition status is sensed for the 3-wire installation.
2. Verify operation of the device.

To verify operation:

If you’re a Reveal customer, verify your installation in Reveal.

If you’re a professional installer using Reveal, use the Reveal Hardware Installer app.

If you’re installing a device in Fleet, use the Fleet Installer Portal.
