Pictures: Sorento Trailer Hitch Install by bikepoet | Photobucket

This really isn't a full how-to, more like a tips to the already included instructions.

Hitch: This was pretty easy as far as car stuff goes. The included instructions are great. Before installing the hitch, I used some rustoleum paint to touch-up the chipped places on the hitch. You will need a coin to unscrew the cover for the spare tire lowering cable. And I think it’s a 19mm, so I used a ratchet and extension. Like others have mentioned, I put the passenger side up on the exhaust, and then screwed in the M10 bolt on the driver’s side. I didn’t have to remove the frame plug from the driver’s side, too. It was really tough to get 110 lb-ft on the 17mm nuts even using my ½” torque wrench.

Wiring harness: I installed the wiring harness box on top of the metal bumper, using the included double-sided tape and added a zip tie to the included zip tie to also hold it down. I had some extra wiring harness loom to put around the 4 bare wires, too. I snapped some pictures in case anyone is interested.

Installed the Curt hitch yesterday. Easy if you have some mechanical aptitude and follow the instructions. A little difficult to position the hitch by yourself. A little more if laying on your back. E trailer has installation videos as well. Am going to install the wiring next weekend. The plug and play kit. Check for the connectors and get the correct wiring kit. The spare winch "nut" on our Sorento is 21mm. I ran the bolts in the threaded holes before installation. Had to chase one hole with a tap to clean the threads. The rear horizontal bolt on right/passenger side needed some "persuasion" to install as the hitch plate was impeded by the weld for the muffler hanger. Took about an hour to complete install. I like the Curt's extra weight rating. Wish it had a bracket to mount the wiring connector. Installed on 2.0 Turbo AWD.

What did you mean by "Like others have mentioned, I put the passenger side up on the exhaust, and then screwed in the M10 bolt on the driver’s side." ?

The rear/tailpipe section of the exhaust needs to be lowered to install the hitch. Propping the hitch on top of the lowered exhaust makes it easier to align the hitch to the left side mounting area to get bolts started.

ordered my hitch last night. also got the wiring kit (for cars without factory towing). stay tuned for the videos to come.
I was under the impression they were pre-wired to the back somewhere and just needed to finish it off more or less. Are only certain models pre-wired?

Thanks for the info on the hitch install. I plan on undercoating my hitch to keep it from rusting. Mine is going in next Tuesday to have the factory hitch installed by the dealer. It was part of the original sales agreement. Apparently, the V6 SX comes with a wiring harness pre installed but the Turbo does not. The hitch was in stock but there was a long delay in getting the harness ordered in. I hope they do a proper job on the harness install. The Mazda dealer installed it wrong on my cx5, causing it to get against the exhaust system, melt and short out. Thankfully the fuse did it's job. They installed a new harness. That was typical of my experience with that dealer. I almost always had to go back and get something done a second time.

i believe our exhaust is on the passenger side. the oem kia harness is located driver side. right before the bumper cover. in fact its attached to the bumper cover.

Our 2.0 Turbo Sorento was pre-wired for a hitch wiring harness. It has the connectors for the plug and play trailer wiring behind the left rear tire. It took about 20 minutes to install the harness.

installed the hitch & wiring today. it was pretty straight forward. the longest part was dragging the 12v+ wire from the rear harness to the battery up front. if you follow the horrible instructions on the harness install, it makes you do a lot of extra steps (removing trunk panels). i found a really easy way to do it. video coming soon. photos are up on instagram @ImStricken06

I installed one on my V6 EX a few weeks ago. Mine is prewired so the harness keep was easy. It is a tight starch for the two plugs with my kit but there is plenty of wire. It was just tapped up a little to tight.

I also had to encourage the rear bolt on the right side. I was laying on my back doing this job & I bet it was less then an hour to do the job. The hardest parts is getting a good position to tighten the bolts down & replacing the cover over the harness once the hitch is installed.

We'll see what mine looks like when it comes back from the dealer next week. So it sounds like the harness is in there for the 2.0 but you still have wiring from the hitch connector to the harness. That may be what they were waiting for at the dealer.
When I was negotiating for the car I thought the harness was included but the sales manager said it wasn't and was charging me extra for one. The sales brochure said it was included so after a bit of a heated discussion he agreed to subtract the cost off the price.

Which plug-n-play harness & hitch did you buy? Models?

ImStricken06, nice video on the hitch. Can't wait for the video on the wiring harness. I'll be adding the exact same stuff on a V6 LX that I purchased this weekend.
