6. 
If you are going to drill a hole, choose a location as close to the camera where the 
power cable comes out of it. Before You Drill A Hole You Must Check And See 
What Is Behind Where You Are Drilling.
 If there are any vehicles components, 
such as electrical parts or fuel system components behind where you are drilling, 
you must take whatever precaution is necessary not to damage them. Remove the 
license plate and camera before drilling. 
7. 
After you have drilled a hole, pass the power cable through the wedge into the 
vehicle.

Next you’ll need to find the vehicle’s reverse lights. Turn the vehicle’s ignition key to 
the accessory position, engage the parking brake and put the car in reverse. Look 
at the vehicle’s tail lights to see where the reverse lights are located. 
To locate the reverse light’s 12V+ wire it will be necessary to gain access to the rear 
of the vehicle’s tail light. 
For help locating the vehicle’s reverse light circuit contact your vehicle’s 
manufacturer for vehicle specific wiring diagrams.
 
9. 
Once you have located the reverse light circuit you will have to 
route the camera’s power cable to that location. You must 
securely fasten the power cable to prevent it from being caught 
on any vehicle
 
component such as the trunk hinge (Fig.6). 
Never route the cable on the outside of the vehicle. 
10.  The sockets for most vehicle’s reverse lights have two wires 
connected to them. One is positive and one is negative, to determine which is 
positive you will need at least a 12V test light available at any auto parts store, or a 
multi-meter. Using the test light, attach the negative lead to a spot on the vehicle 
that has a chassis ground, with the reverse light on touch the other lead to one of 
the wires on the reverse light socket. When you touch one of the wires and the test 
light comes on that wire is the positive wire, if the test light doesn’t come on, that
