"Where is the grommet on the passenger side, what color is it, any information of what you have to remove to see this grommet would be extremely helpful."

This was so annoying for me. I found it easiest to go under the hood and get it from there. Look at the ECU, the grommet is to the right. It's black, like an inch or so wide. I popped mine out, and pushed a sharp piece of metal at the carpet behind. Then I went back in the car, saw where the metal was and cut an X in it. Ran the wire through and was done. I don't know why it took so long...
