This harness plugs straight into the factory wiring, so you don’t have to splice or cut any wires. It connects to the existing plug near the spare tire support and gives you a clean 4-flat trailer connector. It’s a simple plug-and-lead setup that’s ready to use for towing lights.
The 4-flat connector gives you the standard running, brake, and turn signal circuits needed for basic trailer lighting. It’s also the starting point if you plan to upgrade later to a 7-way system for trailer brakes or battery charge lines using an adapter kit.
When you’re ready to add a brake controller or a 7-way socket, this harness works as the base connection. You can plug it into an adapter like the ETBC7 kit to expand your trailer wiring for extra functions such as electric brakes or 12-volt power without replacing the whole setup.
Once installed, you can mount the 4-flat using brackets like part #18144 or #C57202 for a solid, professional look. These brackets keep the connector secure and easy to access when hitching up your trailer.

Today we're going to be taking a look at part number C56110, this is your replacement OEM wiring harness. This product is going to fit certain years of the Ford F150 and the E series vehicles. It's going to supply your 4 way flat plug at the back of the vehicle. Now, this is designed to be an exact replacement for a damaged, or needing to replace OEM wiring harness. Here on the 4 way flat, it's going to come with the protective cap, that way you can protect your connection points when the connector is not being used. Just goes over that area there, and then comes over the connectors.
It's also going to come with your detailed instructions, it's going to come with your cable ties to secure any excess or lose wires that you may have, and it's going to come with self taping screw to make a good ground connection right here with the ring terminal, and white wire. Very easy installation, you do not have to worry about cutting or splicing any of your wires. All you have to do is locate the OEM trailer wiring harness connector on top of the spare tire support, it's usually located on the driver side, it favors the driver side. You're going to insert the new connector. The connector should match up perfectly, make sure it's fully inserted, it's going to lock and secure into place for a nice, tight, secure connection. Then you're going to need to make a good ground connection using an existing screw with the nut, or you can use the supplied self taping screw.
Place that right here through the ring terminal that's attached to our white wire, which is our ground wire. Once you have that connected you can then route the 4 way back to the rear of the vehicle, and then you can secure it in a convenient, out of the way location, near the hitch. Again, detailed instructions, these are going to have pictures that are going to help you through the installation process, very detailed. Once you have that done you can go ahead and use some of the cable ties to secure the wiring, keeping it up and out of the way. That's going to do it for today's look at part number C56110.
