[. . . ] High torque drill suggested for use at Slow Speed of approximately 400 RPM 2. 1/8" carbide-tipped drill bit for starting pilot hole (optional) 4. Phillips head bit for drill (used to set self-tapping ground screw) 7. [. . . ] Sensors should be mounted NO LOWER THAN 18" from the ground and NO HIGHER THAN 30' (fig. Using a grease pencil, mark the final mounting location for the sensors. NOTE: If bumper material is thicker than 5mm (0. 2"), an external bracket will be required to mount the sensors. -1- 4. Determine where the sensor wires will enter into the trunk area or passenger compartment. Many vehicles have a factory grommet to allow routing of wires from the outside to the inside of the vehicle. If you are drilling a hole through a metal body panel to route your sensor wires into the trunk/cargo area, be sure to coat the holes edges with Zinc Galvanizer. Feed the sensor wires through the factory grommet or other opening into the vehicle for connection to the control module (e. g. , into the cab of most trucks or the trunk of passenger cars). Finish by fitting the hole with a rubber grommet, or by using automotive grade silicone to prevent moisture from entering the vehicle. NOTE: Once the wires are passed through, ensure that you have the right amount of slack needed to route to the control module. Make sure that the sensor wires will not be pinched by moving parts or panels. Cable tie the sensor wires behind the bumper, away from any area that is close to the exhaust system or moving suspension parts. Do not pull or yank on the sensor wire were it exits the sensor shaft, as you may damage the inner connections. Mounting the Adjustable Piezo Speaker and Optional LED The piezo speaker has three adjustment positions: Hi, Low and Off. Therefore, you need to mount the piezo speaker to the vehicle interior where it can be easily accessed for adjustment. Route the plugs for both the speaker and optional LED to the area where you will install the control module. Make sure that they will not be pinched by any panels or moving parts. Clean the piezo speaker back mounting area with the supplied alcohol pad, remove the backing strip from the Velcro and firmly press the velcro pad onto the speaker back; then position the speaker into place on any fibrous cloth surface, or mount with the screws supplied. Attach the optional LED using the supplied brackets and double-sided adhesive foam pad , making sure it is in view through the rear-view mirror, or rear center of the vehicle drivers line-of-sight. [. . . ] The target wire will have +12 volts when the vehicle is in the reverse position, and 0 volts in any other gear position. Probe the appropriate wiring harness which heads toward the reverse light connector of the vehicle, looking for the wire which carries +12 volts when reverse gear is engaged, and no voltage when reverse gear is disengaged. Once you have located the proper reverse light power wire, use pliers to connect the RED wire from the unit's power harness using the provided 3M Scotch-Lock connector. [. . . ]
