ECO Button Holder for Renault Clio

thingiverse

If you own a latest model Renault Clio, you must be aware that there is a hidden feature waiting to be unlocked by yourself. A button that enables you to put the car in ECO mode, reducing power and fuel consumption on long journeys. You can see the installation of a standard button in this video: https://www.youtube.com/watch?v=lSSiZ8hzTz8 However, the standard button is expensive and hard to find, so you can print a housing and then connect your preferred button. 3D files include a housing where you can add the right hole for your button and a pre-drilled hole for a standard 16mm panel button. You need a "momentary" button that closes the contact between the two terminals only when it's pressed, not stuck. Because you have to press once to activate the eco mode and once to turn it off. If you want to add some style, choose a button with integrated LED, because the electrical connections of the hidden arrangement under the plastics include power to light up the button when you turn on the headlights at night.

Black is the Ground of the car, white is the signal for the button, and blue is the voltage. If by mistake you touch black and blue, you'll have to change a fuse. You need a 150-ohm resistor because the LED (in my case) is at 12V, while with the engine on, the car battery voltage is up to 14.3V +If you don't have the black cable, you can connect it to any metal part of the car, nut or screw for example.

If you need to bring the car to an official workshop, remove the button.
