I'll measure the diameter when I drill the hole. As I said, it ends up behind the touchscreen near the back side of the cubby.
The best laid plans... When I successfully drilled the hole in the firewall I started to push the cables through. Even though they went in I saw nothing on the inside of the car. When I inspected the hole more carefully from the frunk side I realized there's a double wall.
Here are two photos taken after the first hole was cut and the cable threaded through. If you look closely at the first photo you'll see a solid background -- the second wall.
So I pulled out my drill and put a same size hole in the 2nd wall. But after the hole was cut I encountered light blue material behind the hole -- what appears to be insulation of some kind. The photo below shows that and the two walls. So now I'm tearing my hair out.
Just at that moment I was looking for a solution a thunderstorm threatened, so I had to pack in in for the day and wait until tomorrow to figure all of this out. In the meantime any ideas or suggestions would be very welcome.

Probably not unless I do some damage to something, which will rightfully be my responsibility.
Interesting connector. Methinks I may have seen it somewhere before.
Can you get a picture of the socket itself (front, looking into it, and back, where wires go into it)? Does it look anything like:

Thanks, Mark

I'll take the photo tomorrow.
I am guessing that the first plate you drilled through was *not* the firewall. From what I've read firewalls are usually 2 plates with insulation between them. Likely that blue stuff is NVH insulation. (noise, vibration, harshness)) whose purpose is to keep excessive engine noise/sounds from coming into the passenger compartment and well as reduce the heat transfer from engine compartment to the passenger compartment (not like that matters much on the Model S, lol). You probably have another plate to go through before being able to run those wires. You are going to use a rubber grommet and not just shove the wires through on the bare metal edges, right? IMO I would think your safe to punch all the way through. Looking at the first responder's guide, I don't think you have any high voltage stuff running through that area. I'm not a car expert though so this is purely just my 2c.
Owners, there is an easier way that I posted previously in the Radar installation thread. On the right side of the car, above the battery and just inside of the air box for the cabin are there are two ~ #6 wires going through a gromet about 3 inches down from the base of the windshield. These are orange and supply power for the heater. I was able to punch a hold just adjacent to these wires and gave pleanty of room to pass any wires into the cabin. Much easier and safer IMO. Not Drill baby Drill !

Lloyd, that makes sense, those orange wires are high voltage from the pack (400VDC), and likely come from the DC-DC inverter, that is built into the area just behind the front right wheel well (This can be seen in the "First Responder" video, where they show how to move the dashboard up and out of the way). Just make sure you don't damage any "orange" cables
Easily done as it is about a 3/4" hole for two #6 wires. Lots of room. I used a heated awl, that made a perfect hole just in the right place adjacent to the orange wires.

Maybe it's to route the front sensors for parking/adaptive cruise. They may plug into the back of the center console???
[wishful thinking but would make sense]
