Car/Truck - 4 Parking Sensors Backup Radar System

This is a great little sensor unit. I bought a titanium step bit per other reviews (the hole saw fell apart just trying to make a pilot hole for one of the spots.I installed this on my 2001 F150 Supercrew Lariat.I drill the 4 holes (took 2 days because drilling into the metal bumper killed my battery after 2 1/2 holes).Part way through, since my drill battery died, I decided to do the electrical work. I decided to tap in to the right reverse light. The power cable on the backup sensor unit has 2 wires, red (hot) and black (ground). The reverse light also has 2 wires. Mine had a solid black that was for ground and one with a blue stripe going up the wire for the hot wire. I cut the wire, stripped to expose the copper, tinned both with solder, tinned the power cable with solder, soldered all 6 ends (2 from the cable and the 4 from splicing the reverse light wire). I decided, since I had (barely) enough room, that I would keep the main unit in the light housing because the power cable was short and it would be a nice dry place to keep this located.I ran the 4 sensors wires over across (behind) the bumper and into the hole going into the reverse light area, plugged them in and then, since I didn't want to add wire and make holes/find holes, I ran the LCD/beeping alarm from the back seat and through the rear sliding window, down in front of the truck bed, and looped it through holes of the truck frame until it was in the same compartment as the other wires. My window closed tightly, I poured a bottle of water on the seam and it didn't leak, so this was a great place for me to put mine and, as I mentioned, I didn't have to add any extra wire to get this job done.I then zip tied all of the loose wires so they wouldn't snag on anything while driving and so it looks nice.FINALLY, and this is important, in reading reviews of these various backup sensors, I noticed a lot of people (not really on this one) complained about it constantly beeping while backing up even when there is nothing in the way of the sensors. I pulled each sensor out and realized that each sensor has an arrow pointing up and it says "up". I rotated each sensor to be pointing up and the random beeps are gone and it works great.I recommend this, and rest assured that its doable on a truck without adding extra wire! (as long as you have a rear sliding window and are willing to use it)
