Difficulty level: it is definitely not a job for a beginner or someone not somewhat familiar with how modern cars are assembled. You do need to remove the entire back bumper and then get it back in place, running the wiring from the battery bay to the rear is a challenge, trimming the heat shield and the diffuser takes some patience, and while the wiring directions are very clear, you should be able to use a multi-meter to verify which wire to splice just in case wire colors are different than the directions.

There was nothing that was hard, it just takes some patience and knowledge. It took me about 6 hours total...I could do it a second time in 3.
Any problems breaking tabs while removing your bumper? I read on one thread that this could be a problem.
