This was a simple project and the kit contains almost everything you will need to install your remote starter. It was a time consuming project so keep your afternoon clear and visit Bulldogsecurity.com and look up your vehicle's wiring chart. The chart identifies the wires on your specific model that you need to connect and whether or not you will need a security bypass module or relays. They also have pictures of key locations to help you identify where to find those wires. If I were to do this again, I would order the T-harness to speed up the installation and minimize potential damage to the vehicles wiring.
