1. Mount the alarm in the rear of the vehicle with the sound opening
outward towards the hazard zone.
2. For the models with wires, connect the black wire to the negative
side of the battery or a good chassis ground. For the models with
lugs, connect the bottom post (shown to the right) to the negative
side of the battery or a good chassis ground.
3. For the models with wires, connect the red wire to an independent actuating switch or splice it into the
back-up lights as shown in the diagram below. For the lug versions, connect the top post (shown above)
to an independent actuating switch or splice it into the back-up lights. Please Note: The vehicles supply
voltage must be the same as the voltage rating specified on the alarm you are installing. Any other
voltage applied will void the warranty.
4. For models with a 3-Wire Cable:
• If you ordered a model with a selectable decibel level (66-802S or 66-907S), connect the white wire
with the red wire (BAT +) for the lower dB output, or cut it short and tape it off for the higher dB
output. An optional switch may be installed to allow the driver to select which level the back-up alarm
operates at.
• If you have a dual function model (66-097DF), the white wire is used for an alternate output. Connect
it to the positive side of your power through the switch that controls the alternate function.
• If you have a model with the Night Silent option (NS models), connect the white wire to your parking
light wire, or other switched +12VDC source. The alarm will be de-activated whenever the white wire
has +12VDC applied to it.
