The Guardian Alert™ Backup Warning Device for receiver hitch applications installs easily. The four-step procedure is simple and is not invasive for most vehicles.

Before installing the unit, please check to see that your box contains:
1.) 1 Guardian Alert Hitch Mount Sensor
2.) 1 Notification Display
3.) 1 Wiring Set
4.) 1 7-Blade Connector (optional)
5.) 1 Hitch Body
6.) 1 Display Extension Cable		 7.) 4 Pan Head Screws
8.) 1 Stick Pad
9.) 6 Cable Ties
10.) Warranty Card (not shown)
        and Warning Label
Installing The Guardian Alert™ Hitch System
Please note: Installation will vary depending on the vehicle’s type of receiver hitch.
A.
 If the vehicle’s hitch receiver is open all the way through, the Guardian Alert Sensor wiring will pass out the back of the hitch body through this opening towards the vehicle’s front.
B.
 If the vehicle’s hitch receiver is blocked at the end, the sensor wiring will be passed downward through the slit at the bottom of the hitch body-mounting flange.
To fit the hitch body to the sensor, first remove and discard the 4 screws in back of the sensor. Arrange the wires through the hitch body according to the requirements in A or B above. Attach the hitch body to the sensor using the 4 pan head screws. Ensure that the word TOP on the back of the hitch body flange is UP relative to the words GUARDIAN ALERT on the front of the sensor. Slide foam ring over hitch body.
Step 1
 Slip the Guardian Alert sensor into the receiver hitch until the pins lock. Ensure Guardian Alert label is right side up.
Step 2
 From beneath the rear of the vehicle, connect the 7-blade plug into the towing electrical socket. Connect the 4-pin connector to the sensor and the 2-pin connector to the 7-blade plug.
Step 3
 Feed the 4-foot display cable (part of wiring set #3) along the rear of the vehicle up into the rear of the passenger compartment through a body plug or existing cable entry grommet or around the weather seal on a SUV or van. Coil up and firmly secure spare cable with provided cable ties.
Step 4
 Determine location of Notification Display where it can be seen and heard. Prepare surface with provided alcohol wipe and mount indicator using the provided Velcro™ stick pad.
  • Use the cable ties to secure all cables up and away from moving parts or hot areas. Verify that the connector on the cable set does not hang to the ground when the sensor is removed for towing.
  • Check that cables were not cut or chafed on installation.
  • Install the warning label where it will not be damaged.
Troubleshooting
After making any changes to the installation or vehicle wiring, please return to step 1 and repeat the entire test to ensure that the unit is working correctly.
Testing Procedures
Please follow all of the testing procedures listed below to ensure that the unit is operating correctly.
Step 1

Set the parking brake. Turn the ignition switch on and place the vehicle in reverse. At this time, a green light will appear from the Interior Indicator to indicate the unit has been properly activated.

If the green light does not come on when the vehicle is placed in reverse, check the unit to ensure that it is completely and correctly installed. It is possible if the green light does not come on that there is not enough voltage to the unit. Check the battery with a voltage meter to ensure that there are at least 12 volts going to the system. Disengage reverse, start the engine and idle for 15 minutes to recharge the battery if required then repeat at step 1.
Step 2
 Using a tape measure, mark off a distance of 18 feet straight out from behind the vehicle. Ask a person to stand there. The vehicle should remain stationary while the person begins to walk toward it from behind. When the person reaches a distance of 9 feet from the vehicle, the display should indicate a flashing yellow/green light. When the person reaches a distance of 5 feet from the vehicle, the display should turn to a flashing red /green light and emit a fast audible beep. When the person is within a distance of 3 feet of the vehicle, the display will show a solid red light and the beep should become continuous, warning the driver that an object is dangerously close to the vehicle.
Step 3
 Now find a parking lot or similar open space where there are few or no pedestrians and vehicles. Have an assistant check the area for possible collisions and advise you or the operator when it is safe to reverse. Test the system reversing towards trash cans, curbs, lamp posts and walls.
Sensor Removal For Towing
Step 1
 Reach under the receiver hitch and disconnect the plug and socket.
Step 2
 Depress the pins and slide the sensor out of the receiver.
Step 3
 Keep the receiver sensor in a safe place within the vehicle for re-installation as soon as towing is completed.
Sensor Re-Installation After Towing
Step 1
 Depress the pins and slide the sensor into the receiver until the pins lock. Reach under the receiver hitch and connect the plug and socket.
Step 2
 Test the system to ensure the re-installation is correct.
