Hardware Installation Procedures

Once the location and connection points are defined, follow these instructions:

1. Verify that the engine ignition switch is OFF.

2. Make the following connections:

a. Connect the OBDII converter’s red (Data -) wire to the red

(J1587/J1708 -) wire on the Qualcomm harness.

b. Connect the OBDII converter’s brown (Data +) wire to the brown (J1587/J1708 +)

wire on the Qualcomm harness.

c. For 65-J9322-1 ONLY: Connect the white (Ignition) wire to the same ignition

source as the Qualcomm system. The LDVDSV2 does not have an ignition wire.

3. Unmount the vehicle’s existing OBDII diagnostic’s connector.

4. Locate the OBDII Y cable coming from the OBDII converter.

5. Connect the OBDII male connector on the Y cable into the vehicle’s existing female

connector.

6. Mount the OBDII female connector on the Y cable in place of the vehicle’s original

connector. This will make it available for use by the OEM or other third party service

providers.

7. Secure OBDII converter box and excess cabling using tie-wraps.
