When a vehicle doesn’t come with factory tow wiring, getting power to the trailer lights can be a hassle. The Hopkins Factory Style 7-Way and 4-Way Flat Vehicle End Trailer Connector takes care of that. It plugs into the existing factory port and includes the relays needed to activate the circuits. Once connected, it powers turn signals, brake lights, running lights, and a 12-volt circuit for trailer charging.
No need to choose between connector types. This plug gives you both a 7-blade socket for electric brakes and charge lines, and a 4-flat for simple light duty trailers. Whether you’re towing a camper or a small utility trailer, both connections are ready to use in one housing.
The integrated 7-way provides the dedicated pin locations needed for an electric brake controller signal and a 12-volt auxiliary feed. That means your trailer battery can maintain a charge while towing, and your brake controller has the proper circuit to work as intended.
The connector snaps into place using the included mounting bracket, keeping the sockets secure and accessible at the hitch. Designed as a vehicle-end plug only, it matches the factory look and uses standard pin positions so you can test each function quickly with a circuit tester if needed.
Because this setup is designed as a direct vehicle-end connection, there’s no converter box or splicing involved. It uses existing fuse and relay locations to activate towing functions through factory wiring, making it a straightforward install that looks and performs like original equipment.

Hey, guys. It's Jake here with etrailer. Today, we're gonna be taking a look at the Hopkins 7 and 4-pole trailer connector. Today, we have a 2023 Nissan Titan, and this vehicle's actually equipped with the factory US car connector. It is tucked up right behind this bumper. If you reach back up in there, you can see it.
You can find it. And if you look right under here, you'll see I've got it pulled out. This is what is designed to connect to the 4 and 7-way plug. Now, there's two ways that you can connect this. One way is with the bracket that comes with the kit.
It'll just install like this, and you can, it clips into place and you can mount it up underneath your bumper like so if you want your connector to be down by your hitch. The Nissan Titan is actually equipped with this same shaped hole right behind this plastic bumper. We'll show you a quick clip of it back here, but if I feel up behind there, I can feel the exact indentation of this hole, which this plug is designed to fit. So, I would highly recommend and definitely what I would do is just trim that out from the back side, and then you can take this plug, connect it right into place and then plug your US car connector that comes from the factory directly into the back of it. Otherwise, if you don't and you want to use this bracket to mount it down here for a less invasive installation, you will have to get an extender or extend your wires on your US car connector 'cause we tried it a couple of different ways, and it will not mount very easily down here.
So, again, it's a cleaner installation if you install it up here and it'll give it a much more factory look. Most vehicles come with them up there. That's probably why that plug is back there, but it's really up to you however you want to install. Now, you can see this bracket back here. It is kind of coincides with the license plate bracket, but you can see the fitment is the same as that bracket that comes with our 7 and 4-pole.
It's much easier just to cut this out, cut the plastic out from this backside and then insert your plug from the front and you should be all good to go. You can see here what we're talking about. This plug is not quite long enough to reach out and to plug into the connector up under the bumper, but right here, it would fit perfect. Now, there's gonna be two different ways you can get this kit. You can get it with just the plug and the bracket, which is what we would need for this vehicle. If your vehicle does not have the factory relays, you will need to get the plug, the bracket and the three relays in order to get the 7-pole functions back to the back of the vehicle. We'll show you which relays they are so you can check whether or not you have the correct relays. The relays we're looking for are going to be your trailer tow, your trailer turn left hand, and your trailer turn right hand. That is going to be this brown fuse, this blue fuse and this blue fuse. As you can see, in the kit, we get a brown fuse and two blue fuses. But for our vehicle, we already have those. If you pop the hood of your vehicle, look in this panel, it's right next to the battery. Pop this lid off. If you have those three relays, just pick up the 7 and 4-pole plug and you're good to go. Plug it in and you can start towing a trailer. Well guys, hopefully this video helped you decide whether or not the Hopkins 7 and 4-pole connector is right for you and which kit is right for your 2023 Nissan Titan.
