Great product, I am using the product on two of my cars. No problems, easy to install.

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)

Muy buen producto Fácil de instalar Recomendable al 100%

installed today on a 2012 Jeep wrangler JKU to help with parking and backing out of my buildings garage. took approx 3 hours start to finish. as always, make sure you plan the wire routes before drilling. i ran all four sensors from the bumper, up through the driver side tail light well, then connected everything to the little box in the trunk area. i only had an inch of wire remaining from the sensor on the far passenger side - lucky. the display screen comes with ample wire length, so you can put it wherever you want. tested in several scenarios and this thing is working great. beeped at a bicycle, a brick retaining wall, and even a 5 inch parking curb when i backed into a spot. pretty impressive for the price. no issues with the sensors picking up the spare tire or other phantom objects. i didnt pay any attention to the numeric reading on the display. the beep frequency and light bars are adequate for me. i'll mess with that later. i have to believe some of the negative reviews are due to poor installation or lack of 12V knowledge. just tap into the reverse power and ground in your tail light. i read someone's review that said it beeps even when not in reverse... that's impossible if it was wired correctly. if in doubt, take it to a professional. the only thing i don't love about this product is the start up "beep". if your shifting from drive to park, it beeps because you are momentarily in reverse. Not a huge issue but it annoys me. maybe a half second delay could solve that? still 5 stars. I was on the fence about these DIY sensor systems on amazon, but i am very happy i decided to try it out. i'll update if i have any issues. otherwise, i recommend it. looks good and works well.

Pretty good system especially for the price, the sensor wires could stand to be a couple feet longer, by the time you go across the rear bumper you don’t have much wire left to place the box in a good position. Seems to work reliably but you can get ahead of it if you reverse too quickly so you need to go slowly, distance from objects displayed is pretty accurate. Just a heads up, lots of cars already have sensor placement positions marked inside the rear bumper cover, just drill those positions and it gives a much better install and a factory look.
