Removing wiring from reverse light housing?

[frednoah]

I need to replace my passenger side reverse light housing. There is a burr in the socket that catches/rips off the nub on every bulb I try to put in. I picked up a reproduction housing hoping that will solve the problem.

I briefly looked at things yesterday, and am unsure how the wiring is suppose to be removed from the socket so it can be swapped out. I don't want to break it, so I figured I should ask the experts before proceeding.

School me?
