There is a cruise control unit (circut board) located behind the left side kick panel that you will need, you will also need to get the gas pedal arm, the actuator, there is a different brake light switch that you will have to grab (the clutch switch gets reused) the main switch and finally depending on the year you may have to get a new instrument cluster. I was able to run and solder the wire to mine. The speed sensor is in the gauge cluster. There is an entire wiring harness for the cruise control setup, that goes from the actuator to the cruise control box, to the main switch and both the clutch and brake switches and finally the switch on the combo switch. By the way if you get it all hooked up and it doesn't work there is a test light (I used a simple 12 volt bulb) that can be hooked up to the control and it will flash a code to let you know what is wrong with it.
