On my model, it seemed the top-left was 3.5mm and the bottom 4 were 3 mm.

Me, too, broke the subwoofer connector from the motherboard. I'd suggest removing the padding first so that you can see what kind of connector it is, then pry it loose (insert spudger where the cables enter the connector).

DO NOT REMOVE THE SUBWOOFER CONNECTION. Step 6 IS NOT NESCESSARY.

You can complete this guide without doing step 6 just BE CAREFUL as you already should be.

The subwoofer cable is NOT removable on some models, attempting to remove it, brakes it off the circuit board and them you are @@%#$$, like me. Thanks iFixit. Also it is not necessary to remove it to replace the optical drive.
