No, I don't have a photo and it's been several months since I put it on so I don't remember exactly what it had on it, I seem to remember it was a hole with a slot in one position. I do remember that I had to remove the cylinder like you were going to access the tire and install the housing and then install the cylinder once the housing was on the bumper. And I had to install the housing before the bumper was on the truck. Could probably do after but was much easier off the truck.
When it is working properly, just the silver cylinder comes out when you access it, the black housing stays on the bumper. Sorry, don't remember exactly but it made sense when I did it.
I just went back and looked at the photo's of your bumper and I see the 2 slots that I remember in the hole for the housing. I don't remember there being a ridge on the back of the bumper. I will crawl under tonight and see what I can see.
