I installed self cancelling turn signals and a USB outlet. The following videos document the project.
My videos are really unprofessional and boring, so generally I would say don't even click on the links. Only look at them if your thinking about installing the ST2 self cancelling turn system and you want to see what's entailed prior to purchase, or if your thinking of installing a self cancelling system and maybe nervous about cutting wires.
It seems like most people who use this website would not need any help in this area, but I put it out there because it's easy to do, and may help someone.
