Frunk or front hood firewall wiring access for 2023 Model S Plaid?

[jklevin000]

Has anyone described or found cabin to frunk/front hood firewall wiring access for 2023 Model S Plaid? Want to install laser jammers and have seen pics of completed projects. Also, any recommendations for powering the system, possibly using Powertap l, OBD, or accessory power in center console.

I don't have a plaid but I'm sure it has a fireman's loop pull tab. The black plastic cover should pull off that pretty easy.

Just found this thread as I was about to pose the same question. I see a grommet from the frunk side, but have not dove deep enough on the inside to find the entry/exit point. From the frunk side, it is tough to reach with my large hands.

Someone here posted about firewall access, and I reached out to him, but never heard back.

I ran a wire from the cabin into the frunk for a front mounted parking camera on my 2021+. I forced it through the existing grommet in the driver's side footwell. It was a tight fit and a pain to do, but it worked. I did not snap any photos of that area during my install. I don't know but I suspect the 2023 is similar.

I did once crawl under there a couple of years ago, and it looked like a nightmare of a task. Did you start from inside the cabin or from the frunk?

I ran a standard fish tape from the cabin, through the fire wall and into the frunk area. I then grabbed the cables I had run from the bumper area, through the frunk and pulled them with the fish tape through the fire wall. It's been a few years, but my recollection is that it was very tight and not much space to work with.

Did it! It was actually incredibly simple.

I was trying to just push a wire through, and I could never find it on the frunk side. I imagine the wire was buried inside the harness. Instead, I took your advise and pushed through the grommet using a wire puller. It was really tight, and I became fearful that I may damage some of the Tesla wires. Suddenly, the grommet became a little loose around the edge. This was the "a ha" moment for me: instead of going through the grommet with the other wires, I went around the outside edge of it. I pushed the wire puller through, and was able to easily reach it under the hood. I pulled through several wires for future use.

Sure, the grommet is not a perfect seal anymore, but given there are no engine fumes to come through, I really don't care.

Would that area be exposed to moisture at highway speeds?

Excellent point. Given its location, I highly doubt it. Regardless, I will though some silicon sealer on it
