Hi From Canada, can't help with the project, my 2014 came with them and the back up camera.
I really like the front ones when parking in the garage, I can get to 1 or 2 inch of the wall,
them I can open the end gate with the door closed.
I wonder if your truck would already be wired for the sensors?
And as you mentioned old ones, here is one I have posted before of one I bought for the son, then the daughter took it over as well , BTW She is same age as the car.
Then there is the wifes car in the back ground, I liked that thing, it was a great little car.
