nethole

I've seen a number of threads suggesting that you run the amp power wire through the firewall through the rubber grommet on the passenger side. I just popped off my grommet, and IMMEDIATELY behind the grommet is white foam (or something that looks like foam, maybe insulation material).

Now what?
My vehicle is a 2013 XLT supercrew with 302a package, so either things have changed since people ran these things in the past, or the extra stuff in my package is taking up space others didn't see (or I'm missing something else)

Have the same exact truck and package with no issues of foam. Can you post a pic?

attached are the 'foam' when you remove the one grommet, and a picture of the area to the left of the removable grommet

lighting must be 'odd' because the 'white oval' shows up as 'dark gray' in the second picture, but it's the same spot. There's something behind it, so I can shove a nice large AMP power wire through that hole

The very big rubber grommet to the left in your picture is what I used. There is a nipple on it that can be cut off or as I did cut it 3/4 of the way through. The hole fits 4g very easily and seals. That's what I used.
