As to this ENTIRE guide I have to say - BRAVO - thorough, detailed, complete. Made this keyboard replacement fast, and totaly NON-confusing! Yay!
re: tiny backlight cable - it IS possible to (gently) thread it through it's designated opening after the keyboard has been seated, but you must do that BEFORE you screw it down. I found it easy by using a spudger to lift the tiny connector end through its opening while gently pushing on the keyboard from below (the side where you will screw it in.
This guide was INCREDIBLY helpful! I walked through the R&I in under a half hour, and felt ENTIRELY confident at EVERY step of the (lengthy) procedure. MANY THANKS for publishing such a clear guide, and for making all these impossible to get parts available, since Apple no longer supports the A1211 Mac Book Pro, even off-warranty.
