In order to mount the block heater on the bumper, first you have to remove the inner wheel liner on the passenger side. Once you removed the wheel liner, you will be able to access with the DRL panel , which is pain in the ass to remove. I tried with the trim removal tool, no luck. I was able to get it off with a long flat head screw driver. There are also one clip on the side on the panel, make sure you remove it before you attempt to remove the panel.
