Hey Kevin, yes the EcoHitch part # 306-X7362 that you referenced does fit your 2024 Volkswagen Atltas SE.
If you want trailer wiring too the Tekonsha kit part # 118754 is the kit to go with as it has the most reliable converter box and an easy install. view full answer...
It's possible, Rafael, but it looks like the GVWR of your Atlas ranges just a bit over 6,000 lbs which I personally wouldn't be comfortable with.
So with that said, I'd recommend using a bit beefier ball mount like the B&W Tow & Stow 2-Ball Mount # BWTS10038B which has a 7.5K capacity and has 5" of drop or 5 1/2" rise depending on what you need. view full answer...
So from what I can gather, Marshall, the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118754 may have not been tested extensively to see if it'd be compatible with the 2024 Atlas.
It shows here that there is a chance that this harness possibly won't work with a 2021.5 and up Atlas, so I'm assuming that's why you're experiencing what you're experiencing.
The Curt # C67WR however has been tested and is confirmed via Curt as well to work with your 2024 Volkswagen Atlas. view full answer...
