The default TRANSIT monitored points in the vehicle are:
• Vehicle speed
• Brake activation
• Warning lamp operation (de-acceleration lights)
• Turn signals
• Front door switch operation
• Back door switch operation
• Optional point with Auxiliary (Aux 1 is user-defined and may be used to
monitor points such as wheelchair lifts, inertia sensors, etc.)
The CUSTOM vehicle sensor option allows for most other situations. The letters
that appear on the screen are settable through the menu system. The default settings
are blank.
When using these options, the DEFAULT condition is that the Digital BUS-
WATCH® considers a low voltage (or ground) in the OFF state. A high voltage (5-
15 VDC) is interpreted as the ON state. To switch the polarity of these signals,
reference the Vehicle Sensor Levels Options menu page as shown in Error!

Speedometer Harness Wiring Instructions
The BUS-WATCH® speedometer input wires are designed to be spliced directly
onto the transmission speedometer transducer wires. In some installations, this may not
be possible (i.e. mechanical speedometer, transmission manufacturer warnings, etc.). The
BUS-WATCH® Vehicle Speed Sensor Kit (P/N 750086) may be required.
Refer to the vehicle service manual for speedometer type, exact wire
location, and transmission manufacturer warnings.
