Addendum: TRX-35x-STTRAB Model Control Wiring
Wiring
Control Cable
Activating the Lightbar is done by apVdc to one or more of the lightbar control wires. The control
wires consume only a few milliamps of current and can be used with virtually any on/off switch. There
are five control wires in the Control Cable plus one +Vdc supply feed.
The control wires are color coded and control the functions shown below.
Orange
- Red and Amber lamps (Group 1 lamps)
Blue
- Blue lamp (Group 2 lamp)
Brown/White - Left STT Stop/Turn function
Brown wire
- Right STT Stop/Turn function
Green wire
- Left & Right STT Tail function
Red/White
- +Vdc
Orange Wire –
Turns on the Red and Amber lamps.
Blue Wire –

Brown Wire -
Turns on the Right STT lamp's Stop/Turn function.
Brown/White Wire –
Turns on the Left STT lamp's Stop/Turn function.
Green Wire –

If while the Green wire is activated, the Brown Wire or Brown/White wire is also activated, the Right or
Left, respectively, Stop/Turn function will override the Tail function.

In all lightbars the red/white wire is a +Vdc feed that can be used to power one or
more switches.
