I was thinking same. Unless you really really need the 115V plug right there and nowhere else (and why would you because, cords exist) then why go through the hassle and cost to attempt a retrofitGet either a 12V inverter and run it from the rear 12V port up to the 2nd row, or get a battery powered inverter. Ryobi makes some inexpensive ones.
I had the 115 volt in my 2019 Honda Pilot, I never used it once and had no idea what I would use it forI never had a 115V plug before. I have no idea what I would use them for.
I used the one in my 2017 for chargers and a media player for the RES. Rather than swapping discs all the time, I just put stuff for the kids to watch on a USB drive and they watched via a Micca Speck connected via HDMI. Now that they're older, though, that's not a thing in my use case; I did get an inverter to run more/better charging to the second row if they want to use their Switches on a trip, but my surmise is they'll more likely just use their phones and charge them the built-in USB ports.I had the 115 volt in my 2019 Honda Pilot, I never used it once and had no idea what I would use it for
