8.2 Tapping Into The Reverse Tail-light
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 in12 volts; some voltmeters will read
negative voltage, this means that you have the positive and negative wires reversed.

or

results.
