theres no light for cruise as standard,,,, so as you touch the accelerator clutch or brakes it disengages,, i didnt have a light on my 320c and i dont believe there is even an icon for one on the dash panel..
If you have a preoct or sep 2004 then it is a straight fit with the loom already present.. if after this build date then you will need the additional loom and then have to cut into the wires to connect, there is a how to in the errrrr how too section
