Towing Help

[Dave Follett]

Would like to tow my 3500lb. travel trailer with a 2023 Telluride EX X-Line we may purchase. It has the trailer harness a sway system. Is the harness a 4 or 7 pin cable? I need the 7 for my trailer brakes. Would like to ask several questions about what else do I need besides a receiver unit. Sorry if I'm in the wrong section.

The harness has a 7 pin connector. The trick is that it's not installed, and you (or your hitch installer) will need to buy it from a dealer... Do a search for towing in this forum. There are several threads going back years about the needed hardware for towing.

Edit: If I re-read your post correctly, the truck you are looking at already has a harness. In that case, if it is the harness supplied by Hyundai, then it should be a 7 pin connector. If it's a 3rd party, then you will have to look (and it's not the Hyundai harness, you will probably need to manually turn off the rear sensors to backup!).

Thank you Merlin. I was told that a vehicle with a tow harness also has a small harness to connect a brake controller under the dashboard. It may be in spare tire well, back storage compartment or glove box.

Yes, the harness kit came with the brake controller wiring. I don't have trailers with brakes, so it wasn't an issue for me and I know virtually nothing about it!
