Fog closing light Kia Sportage II (JE) 2010 from South America

In South America, the NSL does not seem to be mandatory. I bought a Sportage II (JE) 2010 here in Ecuador and is trying to upgrade the NSL. I bought a used but original Kia NSL switch in Germany and took it with me to Ecuador, yesterday to my surprise found that cables with plugs are laid right next to the clock, connected, -lamps glow inside -> 1:0 I did not see anything on the rear lights. hten has seen here many times, so I assume that they belong to the original equipment of this model / construction year. Both rear lights each have 4 recesses for 4 bulbs, however, 5 cables arrive at the lamp and the plug connection between the harness and headlight unit also has 5 poles (or as it is called). At the moment it looks like this: Lower light = tail light, in the middle then give turn signal and rear headlights, at the very top the brake light. I hang Here are my 3 questions: 1. Has anyone ever integrated a 5th bulb into this type of rear-view headlight? 2. Is it somehow possible to connect the rear-view light and brake light to a bulb, so that I could use the current recess for the brake light as NSL? 3. Or do I have to add the NSL to the body somehow? 4. If the cables seem to be pre-loaded, it can be assumed that the cables are also suitable for the rear-view headlight. the NSL also arrive at the rear of the return headlight in the cable trunk?
