Looks good. Thanks for the photos. I'm going to do the same thing to my Focus. I'm debating if I should get the trim rings from the US or from China. Don't know if I want to wait 3-4 weeks (although your earlier post said 2 weeks).
Also, was the trim around the e-brake easy to remove to install the switch? And, can you take a photo of where you tapped in for power or post a link to a forum page showing it?
