Installing the TT150 Terminal
Dry Van Trailers
Overview
The TT150 terminal installs outside the trailer. For dry van trailers, the TT150 terminal is
installed on the trailer’s nose surface. The attached TT150 power cable runs from the TT150
terminal to the 7-way receptacle, which recharges the internal battery when a truck is
connected to the trailer.
Thoroughly evaluate the trailer nose area to determine if the TT150 system can be installed
on the trailer. Determine if rivets or VHB tape will be used to secure the TT150 terminal to
the trailer. Typically, rivets are used for installations on dry van trailers. The trailer should be
free of extensive damage in all installation areas. For specific tools required, refer to Tools
and Supplies Needed for Installation in chapter 4.
The TT150 terminal can be installed high up on the nose of the dry van trailer to reduce the
likelihood of tampering and lessen GPS signal obstruction or it can be installed lower on
the trailer, near the 7-way when not enclosed by metal and does not interfere with
gladhand/hose coupler connection operation. It is recommended to install one terminal in
the desired location and verify operation for both GPS and cellular signal reception before
installing additional units.
Installation
Typically, two rivets are used to secure a TT150 terminal to a dry van trailer. The power
cable connects the TT150 system terminal to the trailer’s electrical power source at the 7-
way receptacle. The power cable is 10 feet long and can be cut as needed depending on
where the TT150 terminal is installed. It may be necessary to drill a hole through the 7-way
housing to provide a route for the cable.
