Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side tail lights. You will have to remove the access cover and the tail light assemblies to access this harness.


T-One Connection Location Points Behind Tail Lights

Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


Once installation is complete, the 4-way flat connector will be stowed beneath your vehicle. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.


ModuLite Power Module

A ModuLite power module is built into this T-One connector. With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Video Transcript for Review of Tekonsha Custom Fit Vehicle Wiring - Genesis GV70 and GV80 Trailer Hitch Wiring - TK45VR

Hi there. I'm Michael with etrailer.com Today, we're gonna take a quick look at this Tekonsha T1 vehicle wiring harness with four pole flat trailer connector. This is going to provide a four-way flat trailer connector at the back of your vehicle, to power your trailer's signal light so other motorists can see if you're stopping or turning as you're towing your trailer. This is going to be a custom fit for your 2022 and newer Genesis GV 70 as well as the 2021 and newer Genesis GV 80. So, if you have either one of those Genesis models, this is going to fit right in. It's gonna be very easy to get this installed which I'll go over in a minute, but this is gonna be compatible with your five pole, six pole, and seven pole adapters.

So if you we're to be pulling a trailer that had one of those other kinds of plugs, you're going to be able to adapt this to work with those as well. So, that gives you lots of options there. As you can see, it does come with this dust cap to help protect your connections. Make sure that dirt and debris, that sort of thing, is gonna stay off of them. So, this is going to feature this Modulight tail light converter.

That's going to ensure that your vehicle's wiring matches that of your trailer. Sometimes, trailers are wired differently from your vehicle. So, this is going to convert it to make sure that your trailer's lights will work properly. This is going to be powered from your vehicle's battery to avoid potentially overloading the electrical system in your vehicle. So rather than just being powered from your vehicle's taillights, this is gonna draw power from your battery.

So, it is gonna provide five amps per circuit for your stop and turn lights, and seven point five amps per circuit for your taillights on your trailer. Like I said, it's very easy to get this installed. We do include very detailed instructions to walk you through that process, but I'm just gonna give you a very basic rundown here. So this system is going to tie into your vehicle's wiring. So, unlike other systems, where you have to splice into your wiring, this uses these plugs that are custom fit for your vehicle.

So, once you get access back to behind your vehicle's taillights, you'll find that you currently have two plugs that look very similar to this that are connecting your taillights to your vehicle's wiring. You'll just unplug those and put these in line with that. Plug them in, and then that's going to re-complete that circuit so that your vehicles taillights will operate like normal, whether you're connected to the trailer or not. But then it's also going to send that signal out to your trailer when you are hooked up to it. So, that's going to be very simple to get plugged in place there. So, we're gonna have one for the driver's side. And then we'll also repeat that process on the passenger side. You are going to have a ground wire. They do include a self-tapping screw so that you can get that ground to a metal portion of your vehicle's frame. And then, we're also going to have this black wire here, which is our power wire, that's gonna run up to your vehicle's battery. They do include lots of length of wire here for you to get connected, so you'll use one of the butt connectors to connect this black wire with this wire, run it up to your vehicle's battery. That's probably gonna be the most difficult portion, routing this up to your battery. You do want to make sure that you're staying away from any hot or moving components of your vehicle so that you're not gonna be damaging the wiring, but you can see they give you plenty of ties here, so that you can keep this up off the ground tucked away by your vehicle's frame. Once you get this up to your engine compartment by your battery, you'll take one end of that and connect it. You'll splice this fuse holder here, or you'll cut this fuse holder, and then, you'll use the other butt connector to connect one end of the fuse holder to your wiring. The other end is then going to be connected to your ring terminal, which is going to be attached to your positive side on your battery, your positive post. And, so then that's going to then send that power to the fill light converter, give it power so that it can send the signals to your trailer. They do include a 15 amp fuse that you'll put in at the very end to open up that circuit and allow that power to flow. So, a very simple explanation of how this installs, but it is a very simple process. You're not gonna have to worry about voiding your vehicle's warranty by splicing into the wiring by connecting with these plugs. It's gonna be very simple and it's gonna be, it's not gonna void your warranty. So, overall, like I said, very detailed instructions to walk you through that process. If you're even somewhat comfortable or familiar with wiring and your vehicle, this is gonna be a very straightforward installation for you. Definitely something you can do on your own. You don't need to pay a mechanic to do it for you. So, if you're up for the challenge, this is a great way to go to add that vehicle wiring at the back of your vehicle so that you can pull your trailer legally and safely. So, that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..
