I used a pill container that I got from Walgreens to hold all of the fasteners I removed during the disassembly process. The container has 14 compartments (individual compartments for each morning and evening of the week). I put a small piece of paper in the compartment with the fasteners to note the name and step of the procedure and the size of the tool I used. Hopefully this will be useful when I go to put it back together again.

I used your suggestion to remove the stand-off and then used my left hand index finger to press the tab while rocking the connector side to side with a needle nose pliers. Plug came out easily.

Davo Montiel's tip worked for me. Use the fingernail on your left index finger to press in the tab on the bottom side of the connector and with the right hand use a flat spudger to press in the tab on the top side of the connector.
