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 - C23VV

Hi everybody, Andy here with etrailer.com. Let's 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 your 2019 and newer Lexus UX 250H and on custom fit parts such as this wiring harness I do recommend taking advantage of our vehicle fit guide here at etrailer.com. Simply input the year, make, and model of your vehicle and our fit guide will confirm if this will work for you or if we have something comparable that will work for you. Now this harness is going to give you a four-pole flat trailer connector at the back of your vehicle to power your trailer signal lights. This is going to be compatible with five-pole, six-pole and seven-pole adapters.

Of course, those adapters are sold separately and as you notice here, included with this is a dust cap for the four-pole flat trailer connector and this dust cap is going to cover up those connection points when the plug is not in use. And as you can see, it's going to be a very tight fit, so you're not gonna have to worry about this cap accidentally slipping off. It's gonna do a great job of keeping those connection points clean and free of dust, dirt and grime and debris. Now the black box on the back of this harness is a powered taillight converter. This is going to ensure that your vehicle's wiring matches out of your trailer.

It does connect directly to your vehicle's battery to avoid overloading the vehicle's electrical system, reducing strain on your vehicle's wiring system. And CURT builds each converter using surface mount technology for consistent, reliable performance. This maximizes trailer light yield and intensity while producing minimal heat, ensuring superior operation in rough road conditions. This harness is designed to connect quickly and easily and the connections with the yellow wires are gonna go on your driver's side and the connections with the green wires here are going to go onto the passenger side of your vehicle. And you are going to need to locate your vehicle's wiring harness, which is located behind the driver's and passenger side taillights.

To locate this harness, you will have to remove the storage tray cover and floor access panel. And then once you locate the connectors, you're then going to separate the connectors and you wanna be careful not to break the locking tabs. And then you're gonna insert these T-connector ends between the vehicle wiring connectors and lock them into place. These T-connectors are custom fitted for your Lexus UX 250H, and so these 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 good ground connection.

The ground wire is this white wire and it has a ring terminal attached to it, and it does come with a self-tapping screw. So you're gonna be able to get this grounded to a suitable location such as your vehicle's frame or crossmember. You do wanna make sure that the surface is clean and rust free. Next, you will wanna mount your converter box to a safe out of the way location. You can do that with another mounting screw that you might have on hand or with this included double-sided adhesive tape or maybe even with one of the many cable ties that's included with this kit. Next, you will need to run the hot lead to your vehicle battery. That's the short black wire that's coming out of the converter box. This short black wire is going to get connected to one end of the included bundle of black wire using one of the included butt connectors. And then the other end of this bundle is going to get routed to your vehicle's battery. And once you have this routed to your vehicle's battery, you are going to take this fuse holder and connect one of the wires with the second butt connector to the routed wire and then you'll of course, you'll just snip this in half and take one side of the wire with the butt connector and connect that to the routed wire of the black bundle wire to your battery. Then you're gonna take the other half of the wire on this fuse holder. That's going to get this ring terminal attached to it and then connect it to the positive posts of your vehicle's battery. This does come with a 15 amp fuse and that will go into this fuse holder and then the fuse cap will keep that fuse safe and protected. You can secure any slack or excess in your wiring with the cable ties that I mentioned previously. And then once the installation is complete, the four-way connector will be stowed in an out of the way location within your trunk. The maximum amperage for the stop turn lights is three amps per circuit and for the taillights it's six amps per circuit. Instructions are included to guide you through the installation process and it is also recommended that you use a small amount of dielectric grease on all of your electrical connections. And that grease is going to help keep all of the electrical, prevent electrical failures rather, caused by corrosion and moisture. You can use that grease on the four-pole connector itself and on the the plugs. So if you are interested in taking a look at that grease and picking that up on your screen, I am including our item number. You can just take that item number and put it in the search field of our website. That will take you to that grease and you can add that to your order. Well, that's gonna conclude our look today. I do hope that it was helpful for you. Again, my name is Andy, thank you for joining me.
