You can see that there is a seam in the heel pad that runs side to side. That seam goes where the floor pan transitions from a flat surface to the angled surface.

Here is a picture of how the carpet gets cut for the gas pedal.

Also, there was just a slit cut in the carpet for the high beam switch. There was no grommet around it to finish off the hole.
