Thank you! I've just replaced both bulbs using your method. Tools required: thin copper wire, headlamp, long nosed pliers, screwdriver, 10 mm wrench + 10 mm socket with an extension to remove the battery and air filter housing, trim removal tool.
A couple of suggestions:
- before opening the cap, mark the "closed" position with a Sharpie. Turn the cap to open (don't remove yet), and mark the "open" position.
- secure the bulb connector with a piece of wire as well, just in case.
- on the passenger side, remove the air filter and the two bolts that secure the filter housing. I could not remove it entirely (resonator was still stuck in the fender cavity), but that was enough to wiggle it out of the way.
- the opening on the passenger side has different dimensions. Removing and installing the bulb was easier than on the driver side, but it was rather difficult to press the cap in place and close it with a trim removal tool. I could reach inside the fender with my left hand and press the cap in place, and then turn it in the "closed" position with my right hand fingers (having long fingers helps).
