I have been reading and studying the above tutorial, however I don't want to make changes in my car's stock headlight assembly.
Hence, after searching in the internet for an alternative, I tried this LED to my 2017 Monty and and everything works without any modifications!

I hope this will help people who want to use LED without modifying anything in their monty.
