Bumper is easy, hardest part pulling it is fighting with a 20+ push clips that holds everything together.
Then popping everything on, just make sure the bumper's fender "hooks" or "clasps" line up and don't get bent when you push it on. Everything lines up perfectly.
I would highly recommend upgrading the harness to sealed relays, as show in the picture above by ssbtech. That would have prevented my failure I believe.
