Swing Door Sensor Installation Overview
The swing door sensor kit contains the swing door sensor (with magnet and switch) and an
85-foot door sensor cable assembly. (The replacement swing door sensor kit comes without
the 85-foot cable assembly.)
The door sensor cable assembly can be routed two ways:
• Externally, under the trailer up to the TT210 system mount assembly (along the same
route as the factory wiring and/or brake lines).
• Internally, along the top of the trailer up to the TT210 system mount assembly.
For external cable installation, refer to External Cable Installation Procedure on page 11-3.
For internal cable installation, refer to Internal Cable Installation Procedure on page 11-9.
At the TT210 system mount assembly, the two door sensor cable wires are butt-spliced to the
YELLOW (DOOR-) and ORANGE (DOOR+) wires in the TT210 system power/accessory
cable assembly.
Swing Door Sensor Validation
A simple opened/closed magnetic switch detects when the state of a trailer door changes.
The interval is set up per the customer’s request and state change reports are sent to the
customer, as shown in the following illustration.
