How to Install Reverse Parking Sensors without Damaging the Bumper
What You'll Need
If your reverse driving skills are not as polished as they should be or if you feel uncomfortable when backing up, reverse parking sensors can offer a great deal of assistance. The sensors are able to detect when something is in the path of your vehicle and will sound an audible alert that will notify you to stop and check to see what is behind the vehicle. Installing reverse parking sensors yourself is not that hard, and this simple step by step guide will show you how.
Step 1 - Choose Sensor Locations
Before you begin installing the reverse parking sensors on your vehicle, you need to select locations on the bumper for their placement. So, take your measuring tape to measure the length of your bumper. Then, choose spots on the bumper that are evenly spaced apart. In most cases, you will install two or four sensors. Therefore, take a marking pencil and mark the locations where you want the sensors to be located. Also, make sure that you choose areas of the bumper that are relatively flat. The sensors will not work correctly if they are angled up or down or from side to side. The sensors must face straight ahead so that they can accurately detect things behind your vehicle.
Step 2 - Connect Sensors
Also, before you begin installing the sensors, plug them into the control box. Then, connect the control box to one of your parking lights. You'll need to refer to your car owner's manual for instructions on locating the wiring harness and tapping into the power leads for the parking light. Then, test the connections and make sure the control box in the sensors are working correctly. Once you have finished testing the sensors in the control box, disconnect the sensors. Also, disconnect the car battery to avoid shock or injury while installing the new reverse parking sensors system.
Step 3 - Install Reverse Parking Sensors
Take the drill and begin drilling holes for the installation of the reverse parking sensors. Most of the time, a special drill bit will come with the installation kit that is the right size for the sensors. After you drill holes, make sure to clean up the rough edges or shards that may be left behind. Also, use a buffer or polisher to clean up the areas around the drill holes. This will help to protect your bumper from scratches or corrosion later. Then, follow the directions for mounting the sensors on your bumper.
Step 4 - Install Control Box for Sensors
Find a suitable location for the control box. Most of the time, the control box will be located in the trunk of the vehicle or the cargo space area of a minivan or SUV. Just make sure the control box is installed in a location where it cannot be damaged by water or is not likely to be damaged by cargo. Once you find a suitable location, use the double-sided tape to secure the control box.
Step 5 - Install Warning Siren
You may also want to install a warning siren in the trunk as well. The siren will usually be very loud so placing it too close to the driver's seat is usually not a good idea. Once you find a location for the siren, plug it into the control box and use the double-sided tape to secure it.
