Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C76CR Review

Hello, everybody, this is Jeff at Today we're going to take a look at the Curt T-connector vehicle wiring harness with the four-way flat trailer connector. Now this is a custom-fit part. It is designed to fit on the 2020 Toyota Highlander vehicles, and on a custom fit part, I always like to recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show you if this'll work for your application.Now, this harness provides this nice, four-way flat trailer connector at the back of your vehicle. That's to power your trailer's signal lights. It is compatible with five pole, six pole and seven pole adapters, that we do sell separately.

And it does connect very quickly and easily. All you have to do is locate your connection points behind the tail lights, plug in these T-connectors, one on each side, one on the driver's side, one on the passenger side. Ground's your white wire, right here, and then you'll have this remaining wire. This is your power wire. This'll need to run to your vehicle's battery.Now it does include this tail light converter, right here, this black box.

This is to ensure that your vehicle's wiring will match that of your trailer. This is a power module. It does connect directly to your vehicle's battery, and that's to avoid overloading the vehicle's electrical system. This converter is constructed using SMT technology, which is surface-mount technology, gives you a nice, consistent, reliable performance. It does maximize trailer light yield and intensity, while producing minimal heat, does ensure superior operation in rough road conditions.So, the harness also comes with this nice dust cover for the four-way, so you can use that.

You can just attach it to the plug and you can leave it on there if you'd like, but once you got it on there, when you're not plugged into the trailer, you can just put that cap on and it protects the terminals from any damage, or from the elements.A few specs on this, the maximum amperage for the stop and turn light circuit is three amps per side tail light, six amps total. Basically, it comes with all this laid out here on the table, and just briefly to show you how this runs. Now, it does come with a nice set of installation instructions, that'll describe where your connection points are and how it all connects. But simply what you want to do is start on the driver's side, and you'll take this T-connector that has the red and yellow wires in it. That's for the driver's side.

And you'll unplug the harness behind your tail light. Plug this into that. You'll have a white wire here with an eyelet on it, that you need to connect to a good, clean ground, if there's one nearby. If not, they do include a grounding screw that you can make your own ground.After that's all connected, you'll take the other T-connector, that's the green wire. That'll go to the passenger side. You'll see it's a length of wire. Run that all the way over there, plug it in the same way. Once those are all plugged in, what you want to do is put, this converter's got a little weight to it, you want to attach it to a good flat surface, so it doesn't bounce around. So they do include a nice piece of double-face tape you can use. It also has a bracket on here, with a hole, and you can put a screw in there if you prefer, for once that's all taken care of.Run your length of wire out towards the back. Your last connection will be your power wire. Now, that'll need to go up to the front of the vehicle. They do include this length of wire and some connectors. So if you put a butt connector on there, connect it to one end of this length of wire, run it all the way up to your battery. When you get to your battery, you don't want to connect this directly to the battery, you want to run it through the inline fuse holder. So take the other butt connector, attach it to one side of this fuse holder. The other side of the fuse holder, you take this eyelet connector, and put it on there. Connect that to the battery.And then your system's pretty much ready to go. Just pop open your fuse holder, take the included 10 amp fuse. Install it into your fuse holder, just like that. Once you get it all in, pop that closed. Now, they do give you some extra cable ties to take up any slack in the wiring, but that should do it for the review on the Curt T-connector vehicle wiring harness, with the four-way flat trailer connector.
