SOURCE: need to find the reverse
You did not specify the yr and model of your vehicle, but the procedure is the same, remove the tail light assembly as specified on your owners manual to replace a light bulb. Apply the Parking Brake and turn the ignition switch to the RUN position (do not start the vehicle), press the brake pedal and place the Shifter in REVERSE. Remove the Reverse light bulb and use a test light grounded to the vehicle chassis to find which one of the two wires going into the reverse light socket is the 12v+, once located, replace REVERSE light bulb, place shifter lever in PARK and turn key OFF.
Splice the 12v+ wire and connect the 12v+ lead from your camera to it, get your Ground (-) from the vehicle chassis.
Good Luck!! A HELPFUL - 4 THUMBS - rating for this solution would be greatly appreciated. Thank you for using FixYa.

it does'nt really matter as long as you know which one is positive because you can run the earth wire from camera to any metal part of the vehicle......hope this helps.....cheers.

You can ground the wire to any unpainted metal surface. Find a screw or bolt, loosen it, put the wire under it and re-tighten.

I had the same problem and solved it. Follow the wire harness from the trunk lock located on the trunk lid to the trunk lid hinge torsion bar located on the Driver's side. You will see a electrical connector of wires (male to female snap in black plastic connection). I found a black wire had broken off with a clean cut. This was caused by opening and closing the trunk throughout the years which would bend that wire back and forth until it broke off as a cut. As a result since the reverse lights, trunk lights, rear license plate light and power trunk lock share the same switch integrated into the trunk lock, the open circuit(cut black wire) allows voltage to travel into the truck lock when you shift into reverse. Closing the loop or repair the wire will prevent that. After the repair, I used a strong tape to prevent the lower part of the wire harness to the black connector from moving when opening and closing the trunk.
