Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system.
Features:
This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your rear cargo area on the driver's side and passenger's side. You will have to remove the rear threshold and some interior lining to access this harness. Once you've plugged in the connector, run the red hot lead up to your car battery. Connect the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.
Once installation is complete, the 4-way flat connector will be stowed in your trunk.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
A tail light converter is built into this T-connector. This converter is a battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.
Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.

Today we're going to take a look at the Hopkins Plug-In Simple Vehicle Wiring Harness with the four way flat trailer connector. Now this is a custom fit part. It is designed to fit the 1998 to 2003 Ford Crown Victoria. Now on a custom fit product I always like to recommend for you to go to our website, use our fit guide, put in your year model vehicle and it'll show you if this will work for your application. Now this harness will provide this four way flat trailer connector at the back of your vehicle to power your trailers signal lights. It is compatible with five pole, six pole, and seven pole adapters that we do sell separately on our website.
This does connect very quickly and easily. Basically you just locate your connection points in the rear cargo area. Plug in the connectors one on each side, ground your white wire and then run your power wire to the vehicles' battery. Now this harness does include this weather proof taillight converter to ensure that your vehicles' wiring will match that of your trailer. It is a powered module, it does connect directly to the battery to avoid overloading your vehicles' electrical system. They do use protective connection terminals on this harness to resist corrosion.
Comes with everything laid out here on the table. Comes with the dust cap for the four way flat connector that you can attach to your four way. You can leave it connected if you want, then when you're not plugged into your trailer, you can just put that over the terminals to protect them from any damage or from the elements. Comes with the extra length of wire to connect to your vehicles' battery, an in line fuse holder with the included fuse. It comes with a grounding screw, comes with some cable ties and comes with a packet of terminal grease or dielectric grease for your electrical connections and a nice set of detailed instructions. Few specs on this harness, the maximum amperage on the stop and turn light circuits is 3 amps each side and on the taillight circuit it's 6 amps total.
Basically when you go to install this, what you'll do is go again to the rear cargo area. I would recommend to start on the drivers side and you'll take the connectors here that have the yellow and the red wire in it and then you'll attach this to the connectors on the vehicle that'll match up. Then you'll take the other connectors that have the length of green wire, that's for the passenger side. You'll run this length of wire over to the passenger side and then connect this right behind the taillights on the passenger side. You'll have your white wire with your eyelet on it.
You connect that to a good clean ground is there's one nearby. If not they include this screw that you can make your own ground. Then what you want to do is, your converter right here you do want to attach this to a flat surface, so it doesn't bounce around. They do include some extra cable ties to do that. Then we'll let your last wire, which you'll want to do is this red wire with the butt connector on it, this is what'll connect to your vehicles' battery. They give you this length of wire to run up to your vehicles' battery. Connect one end of length of wire to that and run this up to the battery. You don't want to connect this directly to the battery, you want to go through this in line fuse holder, connect that to the other end. Then once that's connected, you have your eyelet here this will connect to your vehicles' battery. Then pop open your fuse holder, take your included 15 amp fuse, pop it right into the fuse holder just like that. Put your cap back on there and you should be all ready to go. Like I mentioned the terminal grease, you want to put on all your electrical connections that you make to help resist corrosion. But that should do it for the review on the Hopkins Plug-In Simple Vehicle Wiring Harness with the four way flat trailer connector.

Four Years: This unit failed internally after 4 years of regular use; it stopped relaying power for tail/running lights. During the time it worked, it was pretty good. For the price, I expected it to last longer.
When I decided to equip my 1998 Ford Crown Victoria for towing, the cost quoted by local towing and trailer shops were pretty outrageous. It was easy to mount the hitch, but I was skeptical about the wiring. I am not one for cutting and splicing into an existing harness, hoping the results functioned properly. The Hopkins custom harness made it so easy and it worked perfectly. Just plug and play!
Perfect..Reasonable Shipping time
This kit installed easily. The only thing to be aware of is that you will need to run a wire from the trailer light wire harness to the battery. I was able to easily come out of the trunk drain hole, under the felt and run the wire through the frame using a fish tape. I haven't hooked a trailer up to it yet, so I honestly don't know if it works, but I wanted to give 5 stars for installation and customer service. Excellent customer service with these guys. No pics because i was able to hide everything completely.
High quality product. Easy install with easy to read & understand instructions. Worked perfect. I would highly recommend etrailer.com to anyone.
Instillation was was easy as I watched my friend who owns his own auto shop. Having said that, I could see that the construction and layout of the harness is impressive. I have had no problems running the lights on my trailer. Highly recommend this product.
Great product. easy to wire in with excellent instructions from video. No problem after one year.
I have used this type of product from Hopkins many times I love it just plug and play it's worth the money.
