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) 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 Figure 71 on
Page 70.
Speedometer Harness Wiring Instructions
Refer to the vehicle service manual for speedometer type, exact wire
location, and transmission manufacturer warnings.
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.
