There are several posts on the Amazon site, as well as on manufacturers site. The controller and start/stop are quick and pretty easy. No battery disconnect. If you get the controller, you'll want the button imo. The "GTF" post describes recommended adjustment to the Car-Analysis video. 20 minutes to install both.
