No instructions but easy to understand. Assuming you have a newer style of connection and your plug actually matches the switch, the color codes provided should work for you. I wish they had made the bezel around the front of the Switch a bit larger. The switch body is 15.8mm wide, while the face that actually holds it is just 17.8mm wide, just an extra millimeter on either side of the opening. Use NOTHING but a 5/8" drill bit straight into the panel to make the hole or the switch won't hit your face and you will be sad. I speak from experience.
