Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C56339 Review

Today, we're going to take a look at the Curt T-Connector Vehicle Wiring Harness with the 4-way flat trailer connector. This is a custom-fit part. It is designed to fit the 201m6 and newer Nissan Altima sedans. On a custom-fit part, I always like to recommend to go to our website, use our fit guide. Put in your year and model vehicle, and it'll show you if these will work for your application. This part will provide this 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights.

It's compatible with 5-pole, 6-pole and 7-pole adapters that we do sell separately. All this does connect very quickly and easily. Basically, you just locate your connection points, which are in the rear cargo area behind the tail lights. Plug in these T-connectors, one on the driver's side and one on the passenger side. Ground your white wire here. Then you'll have this separate power wire that you'll run to your vehicle's battery.

This does include the tail light converter. This is to ensure that your vehicle's wiring will match that of your trailer. It is a powered module. That's why you'll connect this power wire to your vehicle's battery. The reason they do that is to avoid overloading your vehicle's electrical system. This converter is constructed using SMT or Surface Mount Technology.

It gives you a nice, consistent, reliable performance. It helps maximize your trailer light yield and intensity while producing minimal heat, and it ensures superior operation in rough road conditions. Also comes with this nice rubber dust cap for your 4-way. What's nice about that is you can just attach it to the 4-way plug. Then, when you're not plugged into your trailer, you just put your 4-way dust cap over the terminals, and that will protect them from any damage or from the elements.

These parts are made in the USA. A few specs on this, on maximum amperage for the stop and turn light circuits is 3 amps per circuit. For the tail light circuit, it's 6 amps. Just to go over how this installs briefly, just to give you an idea of where all these parts go, what you'll want to do is, again, it gives you a nice set of detailed instructions that will describe how to install everything and even give you pictures of where your connections are. Basically, what you'll do is start at the rear again. Access your rear cargo area. You'll want to start probably on the driver's side. You'll take this T-connector that has the yellow wire in it. That's the driver's side. You'll find your connectors behind the tail light. Unplug the harness, and then these will T into that. You'll have this white wire with the eyelet on it. That, you want to connect to a good, clean ground, if there's one nearby. If not, they give you a grounding screw that you can make your own ground. Then you'll take the other T-connector with the green wire. That's for the passenger side, and you'll run this length of wire over to the passenger side. Do the same behind the tail light. Plug this in. Once those are all plugged in, what you want to do is, your converter here, you do want to attach this to a surface so it doesn't bounce around. They do give you a piece of double-face tape that you can attach it down with. Then you have your last black wire, which is your power wire. This is what needs to run up to the front of the vehicle, to your vehicle's battery. They give you this extra length of wire to do that. Then you'll take one of your butt connectors, put it on that power wire coming out of the converter, put it on this length of wire and then run it all the way up to the front. Once you get to the front, you'll take your other end. You don't want to connect it directly to the battery. You want to run it to the inline fuse holder. You take your other butt connector, put it on this end, attach it to one side of your fuse connector just like that. Then your other side of your fuse connector, you have this eyelet they include. You put that on there, and this will connect to your vehicle's battery. Once that's all connected, pop open your fuse holder. They include your 10-amp fuse. Push it into place. Put your cap back on there, and you'll be all ready to go. Now, they do include some cable ties to take up any slack in the wiring. That should do it for the review of the Curt T-Connector Vehicle Wiring Harness with the 4-way flat trailer connector.
