Good news, I can help make sure you have everything you need to tow your trailer.
The Curt Class III hitch # C13315, you were looking at does install easily, but I would recommend the Draw-Tite Class III hitch # 76138 instead.
Depending on if your trailer has brakes or not will determine which wiring you will need. Most small utility trailers or jet ski trailers will use a simple 4-way. For lights that are LED or not you will want the wiring harness # 118563. This will power the lights on your trailer. I have linked an installation video of how this installs to your vehicle as well. If your trailer has brakes you will need a 7-way like the # ETBC7 and a brake controller like the # 90195 to actuate them.
Other items you will need when towing a trailer is a ball mount and ball. This will depend on the trailer and your vehicle. I have linked a Help Article that will show you how to measure for the right rise or drop to determine the proper ball mount and ball for your vehicle and trailer. Since you do not have the hitch already installed on your vehicle, I can tell you that the inside height of the Curt # C13127 is 13-1/4 inches and the Draw-Tite # 75217 is 12-1/4 inches.
We do offer a common ball mount kit # 989900. We have determined through customers that these are the most common ball mounts and balls purchased. For added security customers will also purchase a hitch lock like # e98880 and a coupler lock like # 2847DAT.
I have linked all the above mentioned products to this page for your viewing and purchasing convenience.
