Review of Curt Custom Fit Vehicle Wiring C56306

Today we're going to be taking a look at the Curt t-connector vehicle wiring harness with the 7-way trailer connector. This product fits certain years and models of the Ford Explorer. It's going to provide your 7-way blade style trailer connector at the back of your vehicle to power your trailer's signal lights. This unit's designed to connect quickly and easily meaning you don't have to cut or splice any of your wires. All you have to do is locate the connection points along the vehicle's frame reel and then you're going to have these plugs right here. You'd plug in your connectors. These connectors are going to match up perfectly with the ports on the vehicle. They're going to snap lock together for a nice, tight secure fit.

Then the harness is going to run to the back of the vehicle. You want to do that according to the included instructions. It's going to walk you through the whole process step-by-step. I do want to point out that the harness, all the wires are going to be protected by that nice plastic wire loom. That's going to keep the wires together and it's going to keep them safe and secure from the elements. Once your install's complete the 7-way connector is going to be stowed beneath your vehicle, near the trailer hitch. We recommend using the mounting bracket to keep the connector secure.

It's available here at 01:03 and sold separately part # 18138. It's also recommended that you use a small amount of dielectric grease in all your electrical connections like the plugs in the vehicle and the 7 pull connector itself. That's going to help prevent corrosion to the connection points. The unit does come with a protective cover for the 7-way connector. You can see that this piece is actually separated from the harness; you will need to make the connections. The kit is also going to come with your zip ties for securing any loose wires or slack in the wiring. Again, you're going to need to connect each wire to the correct terminal, located on the back of the 7-way plug. In order to gain access to those connection points you'll just need to use a Phillips screwdriver.

We're going to remove these two screws and I want to go ahead and show you that real quick. I'm just going to remove the screw from each side. There is going to be an insert located inside of this plug that will come out the front. That's going to allow you to make your connections. Right here, this is the back of the actual plug. Has the little screws on there so that way you can take the strip back wire, place it around, tighten it down, get everything connected. It's going to have a diagram in the instructions that is going to indicate what wire goes to which terminal.

That way all the functions are matched up correctly. The way that you get the wires through, is you'd place all the wires through the back of the housing here, run them out to the front, make your connections and then when you're done, you just reverse that process. When you're done you just place this back into the housing here. Make sure that you get it seated correctly. Again, all your wires would be connected running out the back. Reinstall the screws, that just secures everything in place. Here on the back, you're going to have another screw, you'd want to tighten that all the way down. That's going to form this seal around the wires. It's going to create that nice closure, that nice sealant keeping water, dirt and debris out of those connection points. When it comes to the maximum amperage for the stop and turn lights we're looking at 10 amps per circuit, for the taillights we're looking at 10 amps per circuit, and for the reverse lights we're looking at 10 amps per circuit. The power circuit is 30 amps per circuit. The trailer brakes, 3 axles are 6 brakes is going to be rated at 20 amps per circuit. The included instructions are going to walk you through the entire process, step-by-step. It's got the nice wiring diagram down there to make sure you get everything connected correctly. That's going to do it for today's look at the Curt t-connector vehicle wiring harness with the 7-way trailer connector.
