Video Transcript for In-Depth Review of the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector-TK85VR

Hi there. I'm Michael with etrailer.com. Today we're gonna take a quick look at this Tekonsha T1 vehicle wiring harness, with this four-pull flat trailer connector. This is going to provide a four-way flat trailer connector at the back of your vehicle, so you can power up your trailer's signal lights, so you won't have to worry about your trailer obstructing the view of your vehicle's signal lights. Other motorists will still be able to see whether you're stopping or turning, because your trailer's lights will have the same indicators as your vehicle. This is a custom-fit kit.

It is going to work for your 2022 and newer Mazda CX5 and CX50. So this is going to be very simple to get installed because it is a custom fit for your vehicle. If you are not super familiar with working on your car, this is definitely a easy way to get transitioned into that because of our plug-and-play adapters here. You're not gonna have to cut into your vehicle's firing, worry about splicing the vehicle's wiring, and that sort of thing. So, it is going to be very simple and straight forward for you.

This does feature this modulite tail light converter that's going to ensure that your vehicle's wiring matches that of your trailer, so you're not gonna have to worry about any compatibility issues. This powered module is going to connect to your vehicle's battery to avoid overloading your vehicle's electrical system, so it's not going to put any more strain on your vehicles electrical system. It will get that extra power it needs from your battery. This will provide five amps per circuit for your stop and turn lights, and 7.5 amps per circuit for your tail lights. Now, as I said this is very easy to get connected, they do include very detailed instructions that will walk you through that process step by step.

But just a very simple overview here, you will locate your connecting points in your rear cargo area, right by your tail lights. So you'll have to get back behind your trim panel area, so right now in your vehicle, you'll have plugs that look very similar to this that are already installed that's connecting your vehicle's wiring to your tail lights. You just unplug those and then plug this in line there, so once you plug these in it's going to re complete that circuit so your vehicle's tail lights will operate like normal, whether you have your trailer plugged in or not. And then it's also going to send those signals out to your trailer. So your yellow wire is gonna be on your driver's side, so you'll plug that in there.

Your green wire is gonna be on your passenger side. They do include some double sided tape here so that you can get this module mounted on a flat surface. You will need to ground this, so they include a self tapping screw here that you can ground this to a metal surface back there, pretty easy to get that put in place. And then, the most difficult portion of this installation is going to be routing your wire up to your battery. So they've got this black wire here, and then some extra black wire for that extra distance. So you'll use one of the butt connector's, get that crimp down on one side, then the other side will go for your extended wiring. You'll run this up to your battery compartment, you want to make sure you're staying away from anything hot or moving that could potentially damage your wire. They do include the zip ties here for you, so you can keep that up off the ground, and where you want it to be. Once you get up to your battery compartment, then you'll take the other butt connector, put it on the other end of that wire, crimp it down. The other side is going to go onto your fuse holder here, so you'll snip or cut this, one side will go to your butt connector that's connecting back to the unit, the other side is going to get the ring terminal put on it and that's going to connect right onto your positive battery post, so it will get the power sent through. Once you have everything installed, then you can install your fuse, and that's included into the fuse holder there and you'll be ready to go. So, very straight forward process. If you don't have lifts to get underneath your vehicle, running that wire might be a little bit time consuming, kind of tedious trying to slide under your vehicle to find places to wrap that. But otherwise it is a very simple and straightforward installation, and then your four-way flat connector will be stowed in your rear cargo area, so that whenever you're ready to tow you can simply pick it up, plug it into your trailer, and you'll get that wiring connected for your trailer wiring. This is gonna be compatible with your five pole, six pole, and seven pole adapters. So, if your trailer uses a different kind of a wiring system you can get an adapter, those are sold separately. We have lots of options available here at etrailer.com that will allow this to then be compatible with your trailer system, and it also has this dust cap to protect your connections from dirt and debris, that sort of thing when you're not using it. So overall, like I said very simple installation with that plug-and-play wiring there. You're not gonna have to cut into your vehicle's wiring, it's gonna provide the power that it needs, and so it is going to be a pretty straight forward installation. I've installed a system like this on my wife's vehicle, and I thought it was very simple to do. Just routing that wire up to your battery, like I said it gonna be the most strenuous portion, but overall very doable for you to do in your garage in the weekend and that sort of thing. So that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..
