It looks like the etrailer picture (see attached) shows a notch cut into the bumper cover to fit the Curt that hangs below the bumper.
From what I have seen these are the popular options, ordering is not meant to mean anything:
1. The OEM look embedded in the bumper and higher off the ground.
- The Kia kit appears to be the only option for this look, all aftermarket options to date leave the bumper cover because the opening for the hitch is below the actual bumper.
- It is available online or from dealers, I've found purchasing the three part numbers was cheaper than the one "kit" part number for all three parts.
- If installed after vehicle delivery you remove the bumper cover and replace it with a black insert.
2. Curt makes part #13420 that is a round tube
- With a tube, perspective is more discrete but the fascia may require a little trimming
- It does sit lower than the OEM, but that could be overcome with a curved ball mount if you need height for the hitch ball
3. Draw-Tite
use to make a part #76403 that is a square tube
- Typically square bars are more visible than round
- Based on the instructions it also requires minor fascia trimming (instructions say a 1" x 5.5" cut)
- Also sold as Reese #84403 (Both Draw-Tite and Reese are owned by a parent company called Horizon Global that also owns Tekonsha products and Hidden Hitch brands)
- Also sits lower than the OEM but could probably fit a curved ball mount
4. Draw-Tite
now advertises part #76420 that is still a square tube
- The installation instructions don't mention any cutting required (I presume they just made the neck part an inch or two longer)
- Also sold as Reese #84420
- Also sits lower than the OEM but could probably fit a curved ball mount
5. Stealth Hitch part #391KIATELL20 + #391CONVPT5L
- Sold as the Stealth Hitch Telluride Rack Pkg or Combo Pkg
- One part is just the hitch if you just want to use it for a bike rack, the other package includes the towing parts
- The bar installs behind the bumper cover and the receiver "goose neck" part can be removed when not towing so it looks like no kit is installed.
- Does sit lower than the bumper but no cutting required
- Probably on the more expensive side
6. Back in Aug 2019 I found this
option in Quebec.
Uhaul advertises three options: Curt 13420, Draw-Tite 76403, or Draw-Tite 76420. If you contact UHaul they might be able to supply some installation pictures.
I did see read some notes of the aftermarket options only fitting the Telluride with the donut spare. I was not aware that there was a difference in spare tires between the trims, but it could be that Tellurides shipped out of the US had a different spec for spare tires. I'm not sure how a full spare would fit with the muffler.
I've owned Curt hitches in the past, but out of necessity had to buy the Kia kit since these options weren't out when I needed to tow. But if you are looking for an aftermarket hitch that is affordable, and you don't want to cut any plastic and you are okay if the square tube is visible some, you may want to look at either the Draw-Tite 76420 or the Reese 84420. And if you want to pay for the install and not worry about the DIY, UHaul does it for $260-285 in parts and might charge you $100-150 to put it in. If you are looking for the towing ability with no trace of the tow package it's going to cost $600-900 in parts.
As for 4-pin wiring I've seen Tekonsha (part #118784) has a plug and play 4-pin flat harness now as an aftermarket option to the Kia part #. As discussed in other posts on this forum there is no plug and play options for a brake controller harness. It must be hardwired/spliced.
