6.5 Reverse trigger connection

The reverse trigger is a positive signal that causes the monitor to automatically turn on
when the vehicle is placed in reverse. We recommend that you tap this signal at the light
bulb connector. To access this you will need to remove the tail light of the vehicle.
Once you have removed the tail light of the vehicle you will use a voltmeter to determine
which lead supplies 12 volts positive power. This is done by setting your voltmeter to dc
volts and probing the wires to determine which is positive and what ground is.
A correct reading on the voltmeter will indicate +12 volts; some voltmeters will read
negative voltage, this means that you have the positive and negative wires reversed.
Note: This step must be done with a voltmeter; guessing or using a test light will yield
incorrect results. We receive many phone calls stating defective merchandise and
this is the single largest mistake when installing a back up camera system.
