This is a complete kit for the 2005-2008 Toyota Corolla and Toyota Matrix. Works with automatic transmission, with no other parts required. Very simple installation with very little disassembly required. The instrument cluster will show a "cruise on" indicator when the cruise switch is on, and an "engage" indicator when you are actually cruising. This kit comes with step-by-step instructions with pictures. Cutting tool mentioned in instructions is not included or required. Vehicle must have electronic throttle. Most AWD Matrix models will have a throttle cable. If so, you will need the 2003-2004 kit.
