## Description

If your vehicle is not equipped with wiring for towing a trailer, CURT custom wiring is the ideal solution. A custom wiring harness -- also called a T-connector -- is a simple, plug-and-play electrical device that plugs into your automotive electric system and provides a standard, universal trailer wiring connection. This is done using two or more vehicle-specific, OEM-compatible connectors to plug into the taillight assembly, eliminating the need for cutting, splicing and soldering during installation. Custom wiring harnesses are made vehicle-specific, and while they are not available for all vehicles, they do offer one of the fastest, easiest and most secure ways to wire a vehicle for towing. This particular plug-in harness provides a 4-way flat connector socket and is designed to be a custom wiring harness to fit certain years of the Toyota RAV4 (to verify your vehicle compatibility, see application info). It comes with all necessary wiring components to establish a reliable trailer wiring connection, as well as a dust cover to keep the connector clean when not in use. You have a picture in mind of your next destination -- maybe it's the boat landing at your favorite fishing spot, maybe it's a campsite that overlooks one of nature's masterpieces, or maybe it's the next big jobsite. However, turning that picture into a reality takes more than just daydreaming. It takes a solid connection and the right amount of power. CURT custom wiring is made with some of the most sophisticated technology in the industry and is designed to install with ease, giving you a long-lasting electrical connection for your towing hitch setup.

## Questions & Answers

**Q: Why does it need the power cable going to the engine compartment?  Don't  the tail light already have power on the harness?**
A: You need the power cord to your battery because the tail lights work off the ground instead of the power from your fail lights

**Q: does this trialer wieing kit is compitable with 2020 RAV4 hybrid xle?**
A: I have this kit installed on my 2019 RAV4 Hybrid Limited and it works great. I am not sure about 2020 but would assume that there is no difference. Keep in mind that for RAV4 Hybrid, the battery is not in the front under the hood but it is at the back on the right side. So you don't need to drill/poke a hold at the back to run the cable down to the bottom of the car and to the front but just run the cable across the trunk. That makes the installation so much easier. Also, if you have the hand free trunk opener, the tow hitch will interfere with it.

**Q: Does my 2020 toyota rav4 hybrid limited, have a wiring connector so i dont have to cut into the vehicle wiring !**
A: No, there is not a connector the RAV 4 has for a simple 'plug and play' connection like I have seen on other vehicles (meaning one connector only). However, you will NOT have to cut into your wiring. This harness comes ready as 'plug and play', it's not hard to install following the instructions. Curt also has an installation video on their website for this harness being installed into the new RAV4. One advantage the hybrid models have is that the 12v starting battery is behind a panel on the right side of the cargo area (see owner's manual), so you won't have to run the extension cable for power to the front of the vehicle like the instructions state, as they were written based on a non-hybrid model.

**Q: Will this work on a 2019 RAV4 adventure?**
A: It worked on my 2020 rav4 xle
