Video Transcript for Review of CURT Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C39DR

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the Curt T-Connector Vehicle Wiring Harness with the 4-way flat trailer connector. Now, this is a custom fit part, it is designed to fit the 2022 Toyota Corolla Cross vehicles, and on a custom fit part like this, I do 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 will work for your application. Basically, this will provide a nice 4-way flat trailer connector to the back of your vehicle to power your trailer's signal lights. It is compatible with 5-pole, 6-pole, and 7-pole adapters that we do sell separately. This kit does connect very quickly and easily, all you have to do is locate your connection points, which are behind the taillight housing, plug in these T-connectors, one on the passenger's side right here, two on the driver's side, ground's your white wire, right here, and then run this power wire to your vehicle's battery.

Now, if you noticed, it does include this black box, this is your taillight converter, and this is to ensure that your vehicle's wiring will match that of your trailer. It is a powered module, that's why it does connect directly to the battery, and that's to avoid overloading your vehicle's electrical system. This is constructed using SMT technology, which stands for surface-mount technology, for more consistent and reliable performance, it'll maximize your trailer light yield and intensity while producing minimal heat. It also ensures superior operation in any rough road conditions. Now, it does even come with this nice dust cap for your 4-way.

So basically, what you do with this is just attach it to your 4-way, and you can leave it attached if you want, and then when you're not plugged into your trailer, you can just put that cap over those terminals, and it'll protect the terminals from any damage or from the elements. Few specs on this kit, the maximum amperage for the stop and turn lights is three amps per circuit, for the tail and running lights is five amps per circuit. And the last thing I wanna show you is where all these pieces go. But again, you'll basically go on the rear of your vehicle, and then you'll gain access to the back of your taillights. And what you wanna do is start on the driver's side, and this T-connectors will plug into your factory connectors in your taillight housing, there's another set of T-connector that you'll plug in.

Once those are plugged in, you have this white wire here that needs to be grounded, you just connect it to a nearby ground or they give you a screw to make your own ground. Once those are all attached, you can run your extended wire with the 4-way on it out towards the back, and then this black box or this converter, you wanna attach that to a surface, so it doesn't bounce around. You have a tab here that you put a screw in, or again, they include some double-faced tape you can use to mount it. Once those are all connected and this is run out the back, your last one is your passenger's side, and the passenger's side will have the green wire. The way you can tell them apart, the yellow wire would be the driver's side, passenger's side would be a length of wire that's green.

Run this over the passenger's T-connector into the back of the taillights over there. Once that's all done, your last connection is your power wire. Now, your power wire needs to be connected to your vehicle's battery, so this power wire here will run to the front of your vehicle, and they give you extra wires to do that and the connectors. So if you take a butt connector, connect it to one end of this wire, and then run this wire all the way up front to the battery. When you get up to the battery, you don't wanna connect it directly to the battery, you wanna run it through this fuse holder. So you'll take another butt connector, attach it to one side of the fuse holder just like that, and then the other side of the fuse holder you take your eyelet connector and connect that to the battery. Once it's all connected, take your included 10 amp fuse, put your fuse in your fuse holder. Once it's installed, put your cap on there, and now, your system's all ready to go. They do give you some extra cable ties to take up any slack in the wiring, and it does come with a nice set of detailed instructions, that'll show pictures of where all your connections are made. But that should do it for the review on this Curt T-Connector Vehicle Wiring Harness with the 4-way flat trailer connector..
