This document describes the procedures to install the Exterior On-Board Unit (OBU) on the outside of a commercial or

passenger vehicle.

The typical mounting location for an Exterior OBU is over the license plate at the upper part of a vehicle’s front license plate

area (Figure 1).

Note: If your state does not require a front license plate, install the Exterior OBU in the area where the license plate would

normally be mounted. If your vehicle does not have a designated front license plate mounting area, contact your tag agency for

other options.

Supplies

• Exterior OBU (may have double-sided tape for secure mount)

• Screwdriver (flat-blade or Phillips depending on your vehicle’s license plate mounting screws)

• Optional two self-tapping threaded screws (customer supplied)

• Optional TransCore Exterior Tag Accessory Kit (19077-01). This kit contains tamper-resistant mounting screws and

wrench.

Exterior OBU Installation Procedures

To mount the Exterior OBU in the license plate area

1. Remove the screws from the license plate area of your front bumper (Figure 1). If your vehicle does not have mounting

screws you will need two self-tapping threaded screws. You can also contact the tag agency to inquire about the optional

TransCore Exterior Tag Accessory Kit.

Note: You may need to use longer screws to fasten the OBU over the top area of your license plate.
