I found through the RPO code that I have rear parking assist. I don’t have the bumper nor any of the wiring or sensors. I plugged the fuse in the obs slot. It says to get the parking assist fixed. My question is what do I need to get to make it work and are there any instruction on how to install it? Any help on where to find the instructions and hardware would be appreciated.

What vehicle are we talking about?

Where did the bumper and the wiring and the sensors go?

It is a 2011 Sierra 1500 slt. It haven't looked for the wiring yet. I don't now where to even start looking other than the back and work my way forward. I have found the harness online along with the sensors. just no information on how to install everything.

I think first step would be to find the wiring on the truck so you know what you need to order for this project.
