I wanted to safely stretch wires from tail LED light to receiver/lights unit. This conduit is placed at the bottom side of the wheel house and connects the side where tail light is installed with interior of the car.
The only tricky part is cutting the holes in wheel house. There are two templates for both sides which should help with right placement of the holes. If the holes, especially the outside one is shifted a bit, you can change the length of the conduit accordingly.
Update - added part for tightening tape for fixing the cable.
