A:Answer Hi Kalven. Thank you for your awesome question. It looks like you're talking about a remote start installation. First, of course you need a remote start kit. From there, in each install we need to have 2 other things - A ball bearing tilt switch and a t-harness kit. The tilt switch is so if you have your hood open, and you're working on the car, you can't accidentally start your vehicle and grind your hands. The t-harness is a kit that makes the installation much easier on our agents. Both of these are very very cheap when bundled with the remote start. Other than those, some vehicles may need another part but those are the 3 main pieces. I hope this helps and made sense. If you have any questions, we'd recommend reaching out to your local Best Buy's Autotech team to get that started. You can find information about your local store at www.bestbuy.com/storelocator.
