I installed the oem door sills about a month ago. The only confusing part was figuring out what connections the diagram was referring to (i.e. the junction box: didn't know what that was). Other than that it's pretty simple once you get familiar with the wiring. The look awesome...
I did the doorsills, I really like them a lot and have gotten quite a few complements on them. I wish they had something for the back seats though. There’s guy on ebay with stickers but I’m really not how well they would look.
As for the carbon trim it’s really cool, but 230.00 for it is keeping me away.
Vertastang did you install the trim or have the dealership do it?
