Review of Curt Custom Fit Vehicle Wiring C56345

Presenter: Today, we're going to be taking a look at the Curt t-connector vehicle wiring harness with a four-way flat trailer connector. This product fits a 2005 to 2007 Ford Escape and a 2005 to 2006 Mazda Tribute. To ensure or double-check that this is a fit for your vehicle, you can always use the vehicle fit guide at This provides a four-way flat connector at the back of your vehicle to power your trailer signal lights. It is compatible with five-pole, six-pole, and seven-pole adapters. Adapters are sold separately. It's going to come with a dust cap for the four-way flat connector.

That way, you can cover up the connection points when your plug's not being used. The dust cap is actually tethered to the housing of the four-way flat connector. That way, you don't have to worry about misplacing that or losing that. The black box is the included tail light convertor. This ensures that your vehicle's wiring matches that of your trailer's.

The powered module connects directly to the vehicle battery through the wiring to avoid overloading your vehicle's electrical system. Now, the unit's constructed using surface mount technology. That's going to offer consistent, reliable performance. What that means is it maximizes the trailer light yield and intensity while producing minimal heat, and it ensures superior operation even in rough road conditions. Now, this is designed to connect quickly and easily. All you need to do is locate your connection points behind your tail lights and then simply plug in all of your connectors. Now, these connectors are custom-fit for your vehicle, so they're going to match up perfectly with the ports on the vehicle.

They're going to push together. They're going to snap lock together for a nice, tight, secure fit. Once you have those connected, you'll need to make a ground connection. That's your white wire with the ring terminal attached to it. Get that grounded to a suitable grounding location with the included grounding screw. Once you have that done, you can go ahead and mount your convertor box.

You want to get this mounted to a safe, out of the way location. You can use the cable tie provided with the kit. You can also use the double-sided adhesive foam tape to get that mounted as well. Then, you'll need to run the hot lead to the vehicle battery. The hot lead is the short black wire coming out of the box. This gets connected to one end of the bundle with one of the included buck connectors. The other end of the bundle runs to the vehicle battery, gets another buck connector attached to it, and contains to one half of the included fuse holder. The other half of the fuse holder gets a ring terminal attached to it and connects to the positive post of the vehicle battery. It does come with a 10 amp fuse. It goes directly in the fuse holder, and it's got the cap that goes over it to keep it safe and protected. Once you have that done, you can secure any excess or slack in your wiring with the included cable ties. Then, once your install is complete, the four-way connectors are going to be stowed in an out of the way location within your rear cargo area. Plenty of wiring here. That way, you can pull it out the back when you need to use it, roll it up, and tuck it away when you don't. It is recommended that you use a small amount of dielectric grease on all of your electrical connections, like the plugs on your vehicle and the four-pole connector itself. That grease is specifically designed to help prevent corrosion to the connection points. It is sold separately and available at When it comes to the maximum amperage for your stop and turn lights, we're looking at 3 amps per circuit, and, for the tail lights, 6 amps per circuit. The unit also comes with detailed installation instructions that will walk you through the whole process step by step. That's going to do it for today's look at the Curt t-connector vehicle wiring harness with the four-pole flat trailer connector.
