So i’ve just bought a 2014 Q3 quattro S-line plus, and i would love to install puddle lights, now it has the slot for the lights in the door, it just needs to be cut out, how do i go about wiring them? Is there any easy to follow guides? I removed the reflective clip on the side of the door and i saw a wire on the inside (see image) is this anything to do with adding brand new puddle lights, do i splice into this?
