Salty,
Thank you so much for documenting this and for answering my questions in the past week
I want to add an addendum for the coupe:
* I found that the 2 plastic screws/clips/rivets inside the cover/door does not need to be removed. Instead, the top 2 torx screws can be access simply by popping off the top center cover trim piece that sits between the bulk head.
* You can just pop off the SOS switch itself to disconnect the cable/connector instead of popping off the entire trim piece surrounding the switch. The switch itself is spring loaded on both sides, so it comes off a lot easier than the entire trim piece surround. Looking at that trim piece, you will break a few plastic clips no matter how you attempt to pry it out.
