It's easiest if you remove the LR wheel. You might also want to completely remove the interior wheel-well liner, but this can also be done partially. Under the wheel-well liner there's a small plastic (ABS) shield that covers the marker's in-board mounting points - this is held in place by end tabs and one hole in common with the wheel-liner. Pop off this cover. With a socket, remove the self-threading nuts from the mounting studs on the marker. In the trunk, unplug the marker light from the rear lighting harness (behind the battery). Pop the rubber grommet and wires from the hole in the clam. Remove the wires, grommet, plug, and light. Install the new marker light, being careful not to over tighten the self-threading nuts. Reroute the wires, connect the plug and check that the light works. Reinstall the tidbits as you found them. Time required approximately 20 minutes. Have fun.
