Video Transcript for T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector-TK66VR: The Breakdown

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the T-One Vehicle Wiring Harness with this 4-way flat trailer connector. Now, this is a custom fit part, it is designed to fit the 2017 and newer Toyota Prius Prime vehicles, and on a custom fit part like this one, I do recommend for you to go to our website, use the fit guide, put in your year and model vehicle, and it'll show you if this'll work for your application. Now, this will provide a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights, and this is compatible with 5-pole, 6-pole, and 7-pole adapters that we do sell separately on our website. Now, this does connect very quickly and easily, it includes everything shown here on the table. It comes with a nice set of instructions that will describe how it installs with pictures.

Now basically, what you'll first do is locate your connection points, which will be in the rear cargo area, and then you'll plug in these T-connectors, one for each side, one for the driver's side, and one for the passenger's side, and then you'll ground your white wire here, and then run this power wire up to your vehicle's battery. Now, this does include the ModuLite tail light converter, which is this black box here, and this is to ensure that your vehicle's wiring will match that of your trailer. It is a powered module, connects directly to the battery, and that's to avoid overloading your vehicle's electrical system. Also, this converter is constructed using SMT technology, which is surface mount technology, gives you more consistent, reliable performance, and will maximize the trailer light yield and intensity while producing minimal heat, also ensures superior operation in any rough road conditions. If you noticed on the 4-way, it has the integrated dust cap with it, so when you're not plugged into a trailer, you just put that cap over the terminals, protects it from any damage or from the elements.

Few specs on this wiring harness, the maximum amperage for the stop and turn light circuits is five amps per circuit, for the taillights, it's 7.5 amps per circuit, and the last thing I wanna do is just briefly go through this when you go to install it. But again, what you'll do is go to the rear cargo area of the vehicle, and the instructions will describe where the connection points are, and you'll find the connection points for these two T-connectors, plugged them in, once you get them all plugged in, you see that you have your white wire with your eyelet on it, that's what needs to be connected to a good clean ground, if there's not one nearby, they do give you a ground screw that you can make your own ground, run your 4-way out the back. Now, this ModuLite box does have some weight to it, so you do wanna attach that to a flat surface, so it doesn't bounce around. It does have a tab on it with the hole that you put a screw through, or they do include a piece of double faced tape you can use. Once that's all attached, you'll have one remaining wire, and it'll be this power wire, and this power wire we'll need to run to the front of the vehicle to your vehicle's battery.

Now, they do include this length of extra wire to run up to the vehicle's battery, and what you'll do with connectors, so you'll take a butt connector, attach to one side of this wire, run it up to the vehicle's battery, once you get up to the front, you don't wanna run this directly to the battery, you wanna connect it through this fuse holder. So you'll take your other butt connector, connect it to one side of the fuse holder, just like that. On the other side of the fuse holder, you put on the eyelet connector, and that'll connect to the battery. Once it's all connected, just pop it open, take the included 15 amp fuse, insert it in there, push it all the way down, put your cap on, and now your system's all protected and ready to go. If you noticed, they do give you some extra cable ties to take up any slack in the wiring.

But that should do it for the review on the T-One Vehicle Wiring Harness with the 4-way flat trailer connector..
