Review of Curt Custom Fit Vehicle Wiring C56407

Speaker 1: Today we're going to take a look at the Curt T-Connector Vehicle Wiring Harness with the 4-Way Flat Trailer Connector.This is a custom-fit part. It is designed to fit the 2018 Jeep JL Wrangler, and JL Wrangler Unlimited, with the standard rear bumper, and without the factory tow package. On a custom-fit part, I always like to recommend for you to go to our website, use our fit guide, put in your year and model vehicle, and it'll show you if this will work for your application.Now, this harness will provide this 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights. It is compatible with 5-pole, 6-pole and 7-pole adapters that we do sell separately on our website. This unit does connect very quickly and easily. Basically, you just locate your connection points, which are in the rear cargo area.

Plug in these T-connectors, one on the driver's side, one on the passenger side. Ground your white wire, and then run your power wire to your vehicle's battery.This does include this black box here, which is a powered tail light converter. This will connect directly to your battery, and that's to avoid overloading your vehicle's electrical system. This converter is constructed using SMT technology, which is surface-mount technology. It gives you more consistent, reliable performance.

It'll maximize your trailer light yield and intensity while producing minimal heat, and it ensures superior operation in rough road conditions.Notice it does come also with dust cover for the 4-way. Basically what you can do is just attach your dust cover to your 4-way, and then when you're not plugged into your trailer, just put the cover over your terminals. It protects them from the elements or from any damage.These parts are made in the USA. A few specs on this. The maximum amperage on the stop and turn lights circuit is 3.0 amps per circuit.

On the tail lights, it's 6.0 amps per circuit.Now it does come with everything shown here on the table. Nice set of detailed instructions that'll describe how to install it with pictures. But just briefly, how you would do this, again, you should go to the connection points, which are in the rear cargo area behind the tail lights. Start on your driver's side. Take this T-connector that has the yellow wire in it.

Unplug your harness behind the tail lights. Plug this into that right there. Take your other T-connector that has the extra length green wire. That's for the passenger side. Run the wire over to the passenger side. Do the same, plug this in behind the tail lights.Once those are connected, this black box, the converter box, you want to attach that to a good flat surface so it doesn't bounce around. It has a little bracket here with the hole in. You could put a screw in there if you would like to. They do include a piece of double face tape that you could use also. They even give you an extra long cable tie if you want to use that to attach it down.Once those are all attached, then you just run your bonded wire here out the back that has the 4-way on it, and then you have two remaining wires, your white wire and your black wire. White wire has an eyelet on it. That's to connect to a good clean ground if there's one nearby. If not, they do give you a grounding screw, that you can drill a hole and put your own ground in.Then the last wire is your power wire. That's this black wire here. This'll connect to the vehicle's battery at the front of the vehicle, and to do that, they give you this extra length of wire with the connectors. You put a butt connector on there, connect it to one end of this length of wire. Run this all the way up to the front. When you get to the front, you don't want to connect this directly to the battery. You want to run it through this inline fuse holder, so take your other butt connector. Connect it to one side of the fuse holder, just like that. Then your other end of your fuse holder, you'll take this eyelet connector and attach that. Then that's what'll connect to your vehicle's battery.Pop open your fuse holder. Take your included 10-amp fuse. Install it in your fuse holder. Put your cap over there to protect it, and your system's all ready to go. Again, 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 Curt T-Connector Vehicle Wiring Harness with the 4-Way Flat Trailer Connector.
