CURT 56434 Vehicle-Side Custom 4-Pin Trailer Wiring Harness,

I enjoy mechanical/electrical projects and this seemed like a good challenge. Was a little worried I'd tear up the trim of my new RAV4 up getting to the wiring. The Etrailer YouTube for the 2023 was very informative. First attempt I gave up. Then I saw the U-Haul video for the RAV4. Re-inspired and with ramps I borrowed from a buddy to get under the car I tried again. Managed to remove the trim w/out damaging it. Connections were fairly easy. The double-sided tape for the module is very sticky but make sure you stick it in the right place (I had to pry up and re-stick because I was afraid it would be in the way of the reinstalled trim). If you don't want to use the self-tapping screw for the ground wire there was a hole for a No. 6 screw (w/metric threads) right where you need it (on 2023 the RAV4). And when you replace the plastic pan rivets under the car push the collars up on them first or they won't go in. Doh! The trim was easy to reinstall, and the tester said it worked. Took me all of a morning.

I installed this in my 2022 Rav4 Prime SE. The hardest part of the install is removing all the trim. This is necessary to run the wiring. The included instructions aren't the best, so I recommend finding a good YouTube video (there are quite a few out there). The install for a Prime is the same as any of the Hybrid models. The hybrid install is easier than the combustion installs because the battery is located in the rear hatch (direct power is necessary due to the need for a converter module, which is part of this wiring harness) - so no need to run wiring to the front of the car. Overall the install took me a couple of hours. Most of this harness is plug- and- play, though a splice is necessary for the wiring to battery connection. All necessary connectors are included. We did use some electrical tape and electrical tubing (not included) to protect the wiring, as well as a couple screws for mounting the converter module (they provided some useless double-sided tape for that).

I installed this kit in our 2021 Rav4 Prime and it seems to be good quality. If you have some extra crimp connectors or, better yet, if you are handy with a soldering iron and some heat-shrink tube, I suggest swapping the yellow (in the red, yellow, black group) and the single green wires as shown in the photo. This requires less panel removal and allows the module to be installed on the passenger side near the the battery and fuses to avoid running power to the drivers side. Then, the three wire connectors can go to the right (passenger) side tail light and the single green wire can run through the metal channel over to the left (drivers) side. As long as you have the soldering iron out, skip the crappy crimp connectors and solder the power lug and fuse block wire too for better reliability.

Easy install and works as it should.

Made hooking trailer light plug on the Escape a lot easier. Works great.

I was nervous making this purchase since the Amazon bot told me this is not compatible. And there was nothing that was. The Curt website was not clear and they did not answer a question I posted. I bought it anyhow, and I'm here to tell you it does work. Installation instructions were one step above a 3rd generation mimeograph and I could not get the double sided tape to peel. Not my wife, either. But once you figure out which connector is which, everything plugged right together. The battery connector needed a bit of creativity to make it work on this car, but it does. I read after I finished : ( that some folks put the box thingie and ground wire on the right side, not the left as I did and the instructions specify. That would definitely be a little easier. There is better access on the right. Did I already say the instruction suck? Thank you Youtube.

Great little item. Was needed for a soso emergency trip. worked great

Fit great. I wired the positive wire to the interior fuse block with an add-a-fuse kit.

I install my own trailer hitches and this one was for a 2025 Toyota RAV XLE. This worked as expected! This is a high quality wiring harness. This is my 4th Curt wiring harness, as we have had 4, RAV 4s.

Worked great on my 21 RAV4. Simple plug and play to the tail lights. Then a ground and one power wire to the battery. Easy clean install.

2 screws 2 clip pins and it comes apart enough to install on 2024 rav4 prime. I watched vid on the tube and I was 15 min from start to finish. But my battery is in back of rav also so very tidy. I leave plug for trailer where spare is then put on top of weather stripping when needed. This way it is no exposed to snow and rain and salt. So won't turn green any time soon.

RAV 4 WIRING Harness is great.

installed on vehicle, install was simple and straight foreward, instruction are clear and well written. after install, tested and all trailer lioghts function properly
