[. . . ] Tape Measure You may also wish to have on hand: 1. Panel tool (Optional - for situations requiring plastic, inner panels to be removed) 2. 3/8 Split Loom (use split loom to shroud sensor wires for a more factory appearance) 3. Wire pulling tool (for routing wires from vehicle's underside through to passenger compartment) 4. [. . . ] Do not mount directly above exhaust pipe opening. From the center of the bumper measure outward to the location where you plan to mount your sensors. Mark the location with your grease pencil as shown in Fig. Ideal Range From Bumper Center: 14" to 18". 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. Cover the sensor wires with split-loom for a factory appearance. 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. [. . . ] The first method is to actually remove the tail light housing from the vehicle. On many vehicles, this can be done by simply removing 2 to 3 screws or bolts, and using light finger pressure. Once the tail light housing is removed, examine where the wires plug in to the back of the light housing. The target wire will have +12 volts when the vehicle is in the reverse position, and 0 volts in any other gear position. [. . . ]
