I installed my EVAnnex lighted T over the weekend. The install was pretty smooth but I did end up breaking some tabs off of the lift gate trim. I glued them back on where I could and I don't hear any rattles so I think I'm OK. I also needed to find a different wire for the rear plate lights because Tesla changes the colors often. EVAnnex suggest that you leave the old residue on the car to help line up the T. I tried that and the result was that it didn't stay on very well so I cleaned all residue off and re-applied with a single layer of 3M adhesive (extra provided) and it worked great.
