anthony: Unplugging the right speaker connector was done in step 23.
In bullet #1 I lifted logic board from left side (nearest battery), tilted toward right side (port side) and pulled to to the left a bit to get ports out of chassis cutouts.
Then I followed bullet #2.
Instruction looks scarier than actual things, doing it is easier. Just be careful and take your time. ;)
Pry the speaker connectors *up and out*. Doing it from the cable's sides, next to connectors, is easier.
The second picture and illustration are not clear enough. The text should say "pry underneath the cable" as I almost broke the fan cable following instruction.
