• 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:

• Vehicle speed

• R - Red wires

• Y - Yellow wires

• L - Blue wire

• B - Brown wire

• W - White wire

• P - Purple wire

When using these options, the DEFAULT condition is that the Digital BUS-WATCH®

IV 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 described in that section of the

manual.

the transmission speedometer transducer wires. In some installations, this may not be

possible (i.e. mechanical speedometer, transmission manufacturer warnings, etc.). The

BUS-WATCH® IV Vehicle Speed Sensor Kit (P/N 750086) may be required.
