I received this unit for Christmas, and installed it in my Ford Explorer. The instructions are not as direct as they could be, but the video helps organize things. I needed to call tech support for a question/clarification and after a fairly long wait on hold (two days after Christmas so I expected that) I got the info I needed by a cheerful tech. The biggest problems with any of these self-installed units (this brand or others) are (1) people who don't have any electrical experience or tools, and (2) installation on cars that have difficult to access wiring (most). The latter can make the difference between a relatively easy or relatively hard installation. The kit electronics appear good for this type of item. All parts (and a small installation tool kit) are included - - except for any small relays that may be necessary for some door locks, security bypasses, and some dome light activiation situations. They are not needed on every vehicle, but many. A couple should be included since they are cheap and these Remote Starters are not. Also, if under-dash wiring is a bit hard to get at (or not), they have plug-in T-harnesses available that range in cost between $10 and $20. Using one would eliminate almost all hookup problems. I didn't use one. My unit works great. I don't anticipate problems, but I have experience in tapping into wiring properly so the connections should last. If there is going to be a problem, it will be in that area. This thing makes getting off to work on a cold, snowy morning more bearable. It's also kinda neat, in general. Take your time or have someone who knows more about these things do the installation. Enjoy. Happy New Year!
