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

Video Transcript for Review of CURT Custom Fit Vehicle Wiring - T-Connector Vehicle Wiring Harness 4-Pole Flat - C27BR

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a look at this CURT T-connector vehicle wiring harness with four-pole flat trailer connector. Now, this is a custom fit part that is designed to fit the 2021 and newer Jeep Grand Cherokee L without the factory tow package and the 2022 and newer Jeep WL Grand Cherokee without the factory tow package. To confirm that this is gonna work for your vehicle, take advantage of our vehicle fit guide on our website, input the year, make and model for your vehicle and that will let you know if this will work for your vehicle. Now, this harness is going to provide a four-pole flat trailer connector at the back of your vehicle to power your trailer signal lights.

It is compatible with five-pole, six-pole, and seven-pole adapters. Of course, those are sold separately. And this does include a dust cap for this four-pole flat connector. It is removable and I do have it removed right now, but you would just simply slide this end over the connector. And then this will cover up those connection points, keeping them clean and free of dust, and debris, and moisture.

Now, the black box is a powered taillight converter. And this is going to ensure that your vehicle wiring matches that of your trailer. It connects directly to your vehicle's battery to avoid overloading the vehicle's electrical system, reducing strain on your vehicle's wiring system. Now, CURT builds each converter using surface-mount technology for consistent, reliable performance. It maximizes trailer light yield and intensity while producing minimal heat, ensuring superior operation in rough road conditions.

Now, this harness is designed to connect quickly and easily. The connections with the yellow wire will go to your driver's side and the connections with the green wire will go to the passenger side of your vehicle. Now, you will need to locate your vehicle's taillight wiring harness behind the driver's side and passenger side taillights. And then you will have to remove the taillight assemblies to access this harness. Then you will separate the taillight connectors, being careful not to break the locking tabs and insert these T-connector ends between the vehicle wiring connectors and lock them into place.

These T-connectors are custom fitted for your vehicle, so they are going to match up perfectly with the connection points on your vehicle. And they snap and lock together for a tight, secure fit. Now, once you have these plugged in, you will need to make a ground connection. And that is this white wire right here with a ring terminal. And it does come with a self-tapping screw. So, you can get this grounded to a suitable location, such as your vehicle's frame or crossmember and just make sure that the surface is clean and rust free. Then you will need to mount this converter box to a safe, out of the way location. And you can do that with another mounting screw that you might have on hand, or with this included double-sided adhesive tape, or with one of the many cable ties that is included with this kit. Next, you will need to run the hot lead to the vehicle battery and that's this short black wire that is coming out of the converter box. And this short black wire is going to get connected to one of the ends of this included bundle of black wire using one of the included butt connectors. And then the other end of this bundle will get routed to your vehicle's battery. And once you have this routed to the battery, you will take the fuse holder and connect one of the wires of this fuse holder with a second butt connector to the other end of this bundle of wire that you routed to the battery. And then the other half of this fuse holder will get a ring terminal that we have right here. And that ring terminal, once you attach it to this wire, will then connect to the positive post of your vehicle battery. It does come with a 10 amp fuse and it goes into this holder as I have it already in the holder. Then it has this cap to keep your fuse within, safe and protected. And it's a nice, tight fitting cap. So, that cap will not come off or become disconnected by itself. Now, you can secure any excess or slack in your wiring with the included cable ties and we have several here, as I mentioned, in this kit. So, you should have plenty cable ties to make sure that your wiring is nice, and tight and secure. And once the installation is complete, the four-way flat connector will be stowed in an out of the way location within your cargo area of your Jeep. When you're ready to use it, you can just simply run this out of your hatch and run it in between the weather stripping of your hatch door and the frame of your vehicle, making sure that this doesn't make contact with the the striker or anything like that. And then you can easily plug this into the wiring of your trailer. Now, the maximum amperage for the stop-turn lights is gonna be three amps per circuit. And for the taillights, six amps per circuit. Instructions are included. And it is also recommended that you use a small amount of dielectric grease on all of your electrical connections, like the plugs on your vehicle and the four-pole connector itself. And it is designed to help prevent electrical failures caused by corrosion and moisture. If that's something you would like to pick up and you don't already have that, I have included the item number on your screen for you. Just punch in that item number in the search field on our website and that will take you to that product. Well, that's gonna conclude our look today. I do hope that it was helpful for you.
