Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

Video Transcript for Review of Curt Custom Fit Vehicle Wiring - Corolla Trailer Hitch Wiring - C26CR

Michael: Hi there. I'm Michael with etrailer.com. Today, we're going to take a quick look at the Curt T-Connector Vehicle Wiring Harness. This is going to allow you to hook up a trailer to your vehicle, so that the light signals that are being operated on your vehicle will be sent back to the trailer that you're towing, so that drivers behind you can see your turn signals, your running lights and your brake lights. Make sure that they know what's going on and can drive accordingly. Now, I just installed a very similar kit to this, on my wife's Toyota RAV4 recently.

So, I'm feel pretty comfortable talking to you about it. Now, this kit is specifically designed for your 2020 and newer Toyota Corolla Sedan. It's very similar across the board, so my experience with this is, it's very easy to install. Even if you're not very mechanically inclined, you don't work on your car all the time, I think you can do this and feel pretty good about yourself having done it.It's basically a plug and play system. So, you just have to get access to your tail light wiring, you're not going to have to cut anything, splice anything there.

These connectors here will allow you to connect right up to your vehicle wiring. So, you'll pull this side that is currently connected on your vehicle. You'll have a wiring piece that looks like this, and you'll have to push in on this tab here to get that to pull out. And, that was one of the hardest things that I experienced, was trying to just get in there, reach back and get that pried down so I could pull it out. So, once you get that out, you'll just plug this in its place.

And then, plug the original into the other side here, so that will recomplete that circuit, so that your vehicle's tail lights will run, even if you're not connected to a trailer.You will have to ground your ground wire here. They do include a self-tapping screw to get that ground in place. You just want to make sure that it's somewhere metal on your vehicle, so that it will operate correctly. And then, your green wire will run over to your passenger side, so this will be on the driver's side, this will run over to the passenger side. Basically the same process, just unplugging your current lights, plug those in onto both locations and you're ready as far as that goes.

You will have to find a place to mount this converter box, and they do include some double-sided tape, just stick to the backside of your converter box, find a nice level place near your tail lights to get that mounted in place.And then your wiring, you can either just have it sitting in the back of your vehicle and pull it out when you're ready to use it, kind of close the trunk on it. As long as you're not in the connection point where it holds it shut, it's not going to cause any damage or anything, so it's very easy to do that. Then you do have to run the black wire up to the battery in your vehicle. For me, that was pretty easy because our RAV4 is a hybrid, so it was right in the back. But, your battery is probably going to be up in your engine compartment. So, they do give you lots of wire to run from the back of your vehicle, up to the engine compartment. And, that's really going to be the hardest part, just making sure that you get that run. They do give you zip ties to keep it up so it's not dragging on the ground, but you want to make sure that you're avoiding anything that's hot or moving, as you run it up in place.And, if you don't have a lift, that can be difficult crawling under your car, but that's really the hardest part, is just getting that wire run. Once you get up to the engine compartment, you'll put your fuse holder in place, in line, and then they give you a ring terminal to attach to your battery. And then, you can put your fuse in. So very simple process, it might sound a little bit intimidating as I'm talking about it, but I really do think that just about anybody can do it with a few simple tools, flathead screwdriver, a Phillips head screwdriver, those kinds of things. You will need some wire crimpers to get your butt connectors on, and those sort of things. But overall, very simple process, it's going to get you out on the road, pulling a trailer behind you.Now, keep in mind, this is a 4 pole wiring setup, so you are going to get this 4 pole end. I had to get an adapter because of the trailer I was pulling, was a 7 pole. So, I got an adapter from the 4 pole up to a 7 pole. It worked great for us pulling the trailer. But, we do have lots of options for you there. So, if your wiring needs are different, we do have options to adapt that for you. And, this is a great system and will easily adapt up to those other wiring setups. So overall, I'd say if you are looking at ways to pull a trailer, you obviously want to make sure that you have those lights to be legal and safe, this is going to be a great option for you.It took me probably about an hour and a half, two hours, something like that. Obviously, if you're running this wire, it might take you a little bit longer for you, but definitely a weekend project that you can do on your own. Get it all set up and you'll be ready to go, so you can pull your trailer. That's going to complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.
