Question: I have a F-150. Drilling holes and splicing is no problem.  How do I know which wire(s) to splice?
Document: After making the holes in the bumper I found they were a tiny bit to big as the whole sensors just went right thru. This was easily fixed using grommets (Autozone for about $3 each) and they fit nicely inside and it still looks like a standard factory install. I used a little gorilla glue to hold them in when bouncing on the roads. Running the wires is the hardest part, and that's just as I'm getting old and can't crawl under the truck so well anymore.
2 weeks after installation, the system works pretty well and it accurate. for the price definitelly worth it; installation was ok in the end but a bit of a pain placing the sensors inside the cut bumper holes (instructions should be a bit more detailed)
I did the installation my self, not help requered, (Little from youtube.com) but just that so is totally funtionalThanks
Great product works as prescribed, easy installation and very easy to use. I would recommend this product to anyone that needs something like this.
But I don't love it. The beeping is annoying when I back down my driveway, as it picks up the angle between the driveway and the road. Also the distance is so short you have to be going really slowly when it picks up the object behind it. All in all it's better than not having anything, but this is not the solution I would recommend.
I purchased this for a 99 Chevy S10. I will be getting one for my other vehicles as well and possibly putting one on the back of my trailer as well. It does need some separate pieces for metal bumpers (I used a Craftsman hole saw 1in, I think about $30 with the bit, hole attachment) but it's well worth it. Everything works perfectly on my truck, left side sensors, right, distance readout, wired via the reverse lights.
poor instructions how to install, and not serving the purpuse, you can't use it for helping you to park, it doesn't show close distances like 1cm.
Very easy to install,  my friend was very happy with the purchase. Will recommend to friends and family. Good product
They do act a little funny when backing up by brush (rear distance changes randomly) but that's understandable as it's not a solid object and it's getting mixed readings.
Don't want to pay a "professional" for purchase and installation of a back-up warning device on your car? Self install this option for a fraction of the price!
Answer: It's the same just put the computer in a safe dry and clean place and all the wire under the bed... So is easy but your problem will be found a place where water don't get so  easy, go and check the F-150 to see it
