Rear bumper?
#2
I did it on my Camaro, can't be much different. Under the the rear hatch, you have to pull up the carpet and ruber trim. They are plastic screws that cannot really be reused after you take them out, but they cost pennies. Inside the rear rearwheel, there are two more plastic screws that need to be removed. Once it is off, the red side blinker marker thing pop out after you remove one philups head screw. Pretty easy.
