CURT 56350 Vehicle-Side Custom 4-Pin Trailer Wiring Harness, Fits Select Toyota Avalon, RAV4 , Black

I don't know what stretch or sheerness is. There is a degree of difficulty to installing this harness. It is a very good harness that connects to the vehicle wiring without any problem. It works well and everything connected without a problem. There are many YouTube videos on how to install the product. I strongly suggest you watch one of them, you'll save yourself some trouble. If you have some mechanical ability you shouldn't have a problem. Again, this is a top quality product.Just wanted to add, this harness & instructions work seamlessly with the vehicle wiring and all connections fit the factory connections. You have to run a cable to the battery to get power to your transformer (not sure if that is correct terminology) that powers your trailer lights.The degree of difficulty is pulling back some of the side panels. Don't let this scare you. E-Trailer has a very good video on how to do this. The installer even shows you the tools you need and tells you they are available on Amazon. I think I paid around $20 bucks for the trim panel tools. You may be able to get by without these tools, but for 20 bucks make your life a little easier.One tip, when running your power line to the battery there is a plastic shroud close to the front of the vehicle that you can partially remove to run the wire. Just be careful in routing so as not to get in the way of moving parts. You shouldn't be on the side where the exhaust is. Secure your wire with zip strips.I added these comments so you won't be discouraged. It's really not that hard and I learned a lot about trim removal.This was installed on a 2018 Rav4

you can't rush the install- it takes time- OR would you rather pay someone 500 to do it- and do it wrong.It's not the harness that's tricky it's taking the molding apart, finding the flashers etc. Have good crimpers and shrink wrap tubing or connectors.Do yourself a favor and go slow and do it yourself and do it right! If anything ever goes south you'll be able to handle np

The product is excellent. The fit was perfect for my 2018 RAV4 Hybrid. Instructions said to disconnect battery under hood, my battery is under the rear floor. Instructions on removing panels to locate tail light wiring was vague and of little help, and pictures were small and too dark. Once the wire was located connection was VERY easy. Kit has everything needed and works Great.

Purchased to attach a hitch to a 2016 Rav 4 and it worked perfectly with no issues! Saved a good chunk of change doing it myself as opposed to paying to have the hitch installed!

Easy to install !

It's another custom fit trailer wiring harness with T plugs. The concept is simple and it works like it's supposed to.The installation videos/instructions I've seen of this on a Rav4 trigger my OCD. The claims of 20 mins are a byproduct of installation tactics that make compromises for the sake of time and making it seem like it's easy. To be fair, if you run the power wire under the body, it is easy. I just have a big issue with running bare wires under the car, mostly cause of issues sometimes when you work on other things.The better way to run this is along the inside of the car. The floor trim has great wire management.- remove the two drive side door sill plates- push the (+) wire through to the front of the rear side trim panel without removing it.- push it through the pillar post trim without removal- remove the side cowl by the brake- peel back the felt to expose the firewall grommet- where the small hole is, pull the grommet into the cabin for access to the closed tube behind it to cut off the end- push the wire through while jiggling. Periodically check the engine bay for cable visibility- Route in engine bay as you want.

The kit was fit well and works, thanks

The install was a little time consuming, wasn't too hard though. Of course I have no lift, so it leaves me to jack and jack stands. It's pretty straight forward on install. The double sided tape sticks good to the module but not the metal on inside of car. I ended up sticking it to the plastic cover you pop back in place ( hope it doesn't come loose ). Takes a little time to tuck the wire and secure nicely. Checked and works properly. The way it's wired it should protect your main wiring on car. If you have short in trailer or pig tail it should only blow the fuse link at battery.

Works perfectly on 2018 RAV4. I picked up a 12V plug for the power, and plug it into socket in back seat rather than run cable all the way to the battery. This means trailer lights only work when vehicle ignition is on, but that’s fine.

very good instruction

It fit

Everything fits perfect as always

Needed to install this to tow a trailer to the east coast. Easy install and worked great. Hopefully it lasts years
