Ok, finally I managed to finish my small project! So here we go with the rest!
Back to back comparison of the tail lights: Front:
Now the process of installation itself.
First, remove plastic covers from both sides which cover the access to the tail light bulbs. I didn't picture this process since I removed mine couple days ago. Might post later so people can have an idea if they never changed their bulbs and accessed this area.
Then, remove 3 screws holding the tail light.
A Big Note here! Loosen them with your wrench enough to unscrew it with your hand. Put the wrench in the trunk somewhere
and continue unscrewing it with your hands and DO NOT let this nut fall down!!! It will be a big pain to get it from there! Believe me! I once dropped a light bulb socket with the bulb in it and couldn't get to this thing. Luckily my hands are skinny and I didn't have to remove the plastic coverings and reached it with my hand. Just trust me - Do not let this nut fall down! SLK is a small car but it seems as if it has a secret Bermuda hole in it
! Keep your hands dry from sweat and it will help you!
Unplug the harness and take the tail light out. Nothing is holding it anymore.
Unplug the harness from the LED Light so it gives you more flexibility to install it. Note: before removing the harness I used a sharpie and marked sockets where they belong in order not to get confused. I used T-top, MR-middle right, etc. But you can choose whatever you like
Then put the wiring through the correct holes so you don't crumble the wires and reconnect it.
Next plug the tail light all the way in. Make sure none of the wires are crumbled! And screw 3 nuts back in. Again - make sure not to drop it
Reconnect the main harness and connect the resistor.
Now, it's time to find the "sweet spot" for our resistor. Although I didn't do it for now (for testing purposes of the resistor: whether it gets hot or not, and also I don't like the idea that the fender gets hot from the sun...but we'll test it
) that's what one member suggested. The credits for this part go to manicdemise

I found FULLY SMOKED LED tail lights. Group buy. - Page 21 - Benzworld.org - Mercedes-Benz Discussion Forum
I'll just quote his words:

I stuck it directly on the inside rear fender wall and had the bottom of it resting of that shelf while the corner was snugged up against the screw."
Here's the picture of this "sweet spot" on the inside:
Hint: use a flashlight so you can better see it. Note here: Do not forget to clean the area from dust before mounting the resistor!
That's what I ended up doing: Just mounted it on the plastic on a double-sided tape and used some zip ties.
