How to: You’ll need an 00-06 Escalade back glass (it has 3 holes for mounting). 07-14 spoiler needs the sides trimmed to fit flush with the glass. I trimmed the backside aswell to fit a little more flush against the glass itself. Drilled three new holes and used three stainless screws with washers to secure the 07-14 brake light to the glass. Along with 3M tape along the top. Then took the two harness and spliced them to make one since the plugs are different for the 00-06 vs the 07-14 brakelight. Then installed.
