How do you remove the plastic brake sensor harness boxes on the rear subframe?

[ewrjontan]

I have my rear subframe out of the car and will be getting it powder coated sometime soon. I am trying to figure out how to get the plastic wire harness boxes off of the subframe. They appear to be held in with a couple of pins but I can't figure out if those just pop out or if they need to be broken off. Any ideas?

Pull the plastic center pins out and the boxes will come right off. The pins just expand the plug portion that goes inside the subframe.
