OK, I figured this out. My car is a 2 door coupe, evidently it must use a slightly different setup than what I found online which I think were all for the sedan. I should have just looked in my owner's manual which showed all the details!

There are only 2 light bulb connectors in the quarter panel on each side, not 3. These are the round ones (picture attached showing one pulled out.) The third, rectangular "connector" does not carry a light bulb, rather it houses a sensor which presumably is what determines if a bulb is burnt out. This I learned here: . This is also what distributes the power to the 2 bulbs -- the wires first come to this "connector" and then go to the 2 bulb connectors.

The upper bulb is the tail light and turn signal (2 filaments). The lower bulb is the tail light and brake light (they call it the stop light). Both bulbs are 3057 (not 3057R which is Red). OEM is Sylvania. Also called 3057LL for long life, there are other version such as LED etc.

The bulbs remove by twisting the connector 1/4 turn anticlockwise, pulling the connector with bulb out of the opening (a little tight since the wires, especially for the lower bulb,, are short) and then pulling the bulb out of the connector. The wiring does not pull out of the connector, unlike what is shown in some online videos.

Quite straightforward once you figure it out. Posting this in case some others find themselves with the same questions.
