Video Transcript for Hopkins Custom Fit Vehicle Wiring - Trailer Hitch Wiring - HM11140525 Review

Today we're going to take a look at the Hopkins Plug In Simple Vehicle Wiring Harness, with the 4-Way Flat Trailer connector. Now this is a custom-fit part. It is designed to fit the 2010 and newer Ford Mustangs. Now 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'll work for your application. Now this harness provides this 4-Way Flat Trailer connector at the back of your vehicle, to power your trailer's signal lights. It is compatible with five pole, six pole, and seven pole adapters, that we do sell separately on our website.

This whole kit will connect very quickly and easily. There's no cutting or splicing of wires. Basically, you just locate your connection points that are in the rear cargo area, behind the tail lights. Plug in these connectors, one on each side. Ground your white wire and run your power wire to your vehicle's battery. This will include this tail light converter, which is this black box, here.

This is to ensure that your vehicle's wiring'll match that of your trailer. It is a powered module, means it connects directly to the battery. That's to avoid overloading your vehicle's electrical system. On your connectors here, they have protective connection terminals to help resist corrosion. Comes with this nice dust cap for the 4-Way. You can just attach that to the 4-Way plug and you can actually leave that attached if you prefer.

Then when you're not plugged into your trailer, just take your cover, put it over the terminals, and that protects them from any damage or from the elements. Comes with everything shown here, on the table. Nice set of detailed instructions on how to install everything, but it's pretty simple to install. All you have to do is start at the rear of the vehicle, again behind the tail lights. You want to start on the driver's side. You'll take this connector that has the yellow wire in it.

You'll connect that behind the driver's side tail lights. Plug that into the harness in the tail lights. Then you'll take this other connector that has a length of green wire and that means it'll run over to your passenger side when you get over there, behind the tail lights. Same way, you'll plug this in behind it. Once those are all plugged in, your converter here, you do want to make sure to attach that to a good, flat surface. They do give you some extra cable ties that you can run through here to hold it down into place. Then you'll have your two wires remaining, a white and a red wire. The white wire, with the eyelet on it, that's for your ground. You want to connect that to a good, clean ground if there's one nearby. If there isn't, you can use this grounding screw to make your own. The power wire has the butt connector on it, the red wire. That would need to run to your vehicle's battery, up to the front of the vehicle. They do include this length of wire to do that. What you'll want to do is take one end of this length of wire, put it in the butt connector, and make your connection. Run this all the way up to the front. Once 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. When you get there, you just take the side that has the butt connector, install that, and then your other side of your fuse holder will have this eyelet, that'll go onto the battery post. Once you get that all installed, take your included 20 amp fuse, pop it into the fuse holder, just like that. Put your cap on and you'd be all ready for your system to go. Now again, they have some extra cable ties to take up any slack in the wiring and then they give you a nice package of terminal grease or dielectric grease, and what you want to do with that is, anytime you make an electrical connection, like at these plugins, you want to put some grease on there, and same way on the 4-Way. Put some grease on that so when you plug into your trailer, that dielectric grease'll help prevent any corrosion at those electrical connections. That should do it for the review on the Hopkins Plugin Simple Vehicle Writing Harness with the 4-Way Flat Trailer Connector.
