Tesla should really put one of these in the model Y. No instructions whatsoever but when you try to install it, it is pretty intuitive. The pieces only really fit in one place each and they are molded in such a way that they kind of "key" into their appropriate positions. Make sure you clean the installation areas thoroughly with alcohol and take your time ensuring that the tape sticks properly. I also waited a little while for the tape to adhere before I put in the screen itself. The retractable screen is very good quality. It retracts smoothly and has some tension so it shouldn't bind at all. The pegs where it engages the back moulding could be slightly shorter so be a little careful when hooking it at the back. It's still a one handed operation though. This screen in my honest opinion is a must have for any Tesla model y owner. Tesla should've really included something like this instead of the cheap piece of junk that they call a cargo cover.
