Installation
Vehicle Wiring Connections
Brake
Connect the wire marked “BRAKE” to the vehicle harness. Tap into the brake circuit so that current is sensed only when
the vehicle brakes are applied.
Power
Connect the wire marked “IGNITION,” with the fuse holder, to an ignition switched power source so that the VORAD will
only power up, when the ignition switch is turned to the run position.
Turn Signals
The wires marked “RTURN” and “LTURN” are used only if mounting side sensors on the vehicle. In this case tap into the
turn-signal indicator circuits.
Ground
Connect the wire marked “Ground” to a battery negative location.
