Got this. Install was very easy. Hardest part was dealing with the trim (as others have said). Works as described!
EDIT: Not sure if this would void your warranty, but don’t plan on being able to take it out when you go for a service. The trim will break if you keep removing it. One of my clips broke a little (I was able to repair it). No way would I want to be taking the trunk trim apart on a regular basis - I think it would get destroyed. Niche claims the module doesn’t write to the car’s software, so it may not show up on a diagnostic.
