Video Transcript for Hopkins Wiring - Trailer Connectors - 46365 Review

Today, we're going to review part number 46365. This is the Hopkins Plug and Tow short-proof tail light converter. This converter will protect your tow vehicle and itself from any wiring shorts. It has a four-way flat connector right here which includes the dust cap for it. The spec on this is 8 amp capacity per function on this harness. Each kit will include everything that's needed to complete the four way flat installation. The kit includes the wiring harness itself, extra length of wire to run to the battery, an inline fuse holder, some wire connectors, a grounding screw, some dielectric grease, the dust cover for the four way, and some cable ties to take up any length of wire that might need to be ...

that keeps it from hanging down. What they do recommend is when you go to install this at the back of your vehicle, these wires do need to be tapped into the wires on your vehicle. It is recommended to use a circuit tester to test the functions of the wires. You don't always want to go by color so you always want to test the function to match them up correctly. This converter is a power converter, has circuit protection which is in a nice weather-proof double molded design. The circuit protection will guard the tow vehicle and the converter itself from any shorts.

If there is a short, it does reset automatically. The powered and tail light converters, they will tap into your tow vehicle's wiring system using this power wire and it draws the power for your tail lights directly from the battery. This wire is hooked up to your battery and it bypasses your expensive electrical components on your vehicle. Basically, when you go to hook this up, what you'll do is go to the back of your vehicle and then you'll tap into the tail light circuit. The yellow would be for your left turn or the driver's side tail light so using these connects you'd tap into the circuit. The brown would be for your tail light circuit.

The red is for your brake light circuit. The long green will run along to the passenger side and that's for your right turn or your passenger side turn signal. Then you have your white wire with the eyelet on it, that needs to be connected to a good clean group. Then, here's your four way on this end with a length of wire that will run out the back and plug into your trailer. When you're not using it, you can coil the wire up and put it in the rear of your tow vehicle. Again, they mention they do have the ...

I'm just going to put the four way on just to show you how that would work. Just put your four way cover on there. Then, when you're not plugged into the trailer, what you can do is just put your cover on. With your cover on, you can see it will protect those terminals from any damage or from the elements themselves. When you do make your electrical connections, they do recommend to use the dielectric grease to help resist corrosion. Wire connectors again are used to tap these wires in. Then on your last wire we have here that needs to be connected, we need to run to the battery. Basically, this is your power wire that powers the converter. What you'll need to do, it has a butt connector on it. You'll take this extra length of wire and tap it into there then run this length of wire all the way up to the front where your battery is. Then using the other end, you'll just attach that. You don't want to put this right to the battery first. You want to run it through the inline fuse holder. You'll attach it to that butt connector and then this other side of the wire on the inline fuse holder with the terminal on it, will connect to your positive battery post. If you notice, it comes with the included 20 amp fuse already in the holder. Then with that all connected, what you can do, is go back to your back of your vehicle, plug this into your trailer. Then it should power the lights on your trailer. That should do it for the review on part number 46365. This is the Hopkins Plug and Tow short proof powered tail light converter. .

This product worked perfect for one day. The second day we used it connected to a trailer it melted and almost caught on fire. I have not found any of these light adapters that work for more than a week but this one almost caught on fire. 679292


If you are consistently having issues with tail light converters, it sounds like there may be a short somewhere on your trailer or vehicle that is overloading the system. To check for a short, it is a good idea to check all of the wires running from your lights to the converter. Make sure they are not frayed or damaged and allowing the wires to touch bare metal on your trailer or vehicle. If you find any damage, replace or repair the wire to stop this wire short. Also, this converter does have a comparatively high amp rating at 8 amps per function. This amp rating would allow for more heat to build up in the unit before melting the circuits inside the converter.

For years I had trouble with my trailer lights working properly until I installed this wiring harness kit. Having the hot wire come from the battery all the way back to the converter made all the difference. Now I can confidently plug in any variety of trailers and know that the lights will work the first time without any fussing around. This was definitely a great investment for my vehicle. 561623

I bought the converter box with a hitch for my Sprinter. It was easy to install and works fine. It did not interfere with the MB lighting system monitor, and functions flawlessly. Highly recommend the Converter and etrailer. 411425


Everything is still working as it should. So glad I saved the money and went with your product.

I did this install at the same time with the hitch. Several steps are worth doing only once since a couple of panel and turn signals are out already. Goggle helped with some steps that were specific to my Audi A-3. 395529

Hi Installed my converter on a 98 Valkyrie w a CSC Trike kit on it. Ive converted ALL the lights to LED and connected to a Harbor Freight trailer w/ LEDS. Works GREAT! Im having a small problem with trailer turn signals at the moment, but that is a wiring problem on MY part! I WILL continue to purchase product from etrailer!

  • Recommended Trailer Wiring Harness for 2017 Toyota Tacoma
  • The Plug-N-Tow (R) Short Proof Powered Taillight Converter - Heavy Duty # 46365 can be used on your 2017 Toyota Tacoma and will work fine. However, I recommend a wiring harness that makes installation easier and doesn't require splicing that also draws power from the battery to protect your vehicle's electrical components. I recommend the Tekonsha T-One # 118685. This harness plugs into your factory wiring already present behind the tail lights with quick connects and then a hot lead...

  • Adding a 7-Way Trailer Connector to a 2004 Toyota Sequoia without Factory 7-Way
  • First, if your 2004 Toyota Sequoia did not come with a factory installed 7-Way trailer connector then replacement connector # 20137 is not going to fit. The connection points will not be present to plug it in. If no factory harness is present you will need to hardwire in a 7-Way. To hardwire in a 7-Way you will need 2 parts, 4-Way flat harness # 46365. Then to add a 7-Way you will need # ETBC7. I have included links that explain the ETBC7 installation for you. It is odd that your...

  • Trailer Wiring Recommendation for a 2013 Chevy Express Van
  • What I would recommend you get is a Curt Custom Fit Vehicle Wiring # 55540. This wiring kit plugs inline with the tail lights of your vehicle and will activate the trailer lights of your small trailer. Curt has determined that you do not necessarily need a powered unit like the Hopkins Converters # 46255 or # 46365 and since your trailer only has two lights on it I think the # 55540 would work well for you. The main difference between the # 46255 and the # 46365 is that the # 46365...

  • How to Test Hopkins Converter kit # 46155 For Internal Short
  • If you have 12 volts on the power wire of the Plug-N-Tow (R) Short Proof Powered Taillight Converter # 46365 and you tested it like you did then the converter has an internal short and would need to be replaced. Also make sure the fuse holder has a good fuse in it too. Test the wires going into the box of the converter box for voltage with a circuit tester like the # PTW2993 to see if there is voltage going into the box when the taillight functions of your vehicle are applied, and then...

  • Troubleshooting No Brake Lights Working After Hopkins Wiring Install # 46365
  • You will need to use a circuit tester like part # PTW2993 to find the circuit that only sees voltage when the brakes are applied and use it for the stoplight circuit for the # 46365. It sounds like maybe you haven't found the correct circuit to use yet and that is why the stoplights aren't working. You should note that the recommended trailer harness is the part # 118526 that is a custom fit harness that would be much easier to install than the # 46365. I attached an install video

  • I did some digging and found that the Curt trailer hitch # C11391 does fit the 2013 Honda Civic Sedan si model so you can use it. I have included a link to the installation instructions for you. If you will be using the hitch for something like a bike rack or cargo carrier you will need to make sure that the accessory is rated for use on a Class I trailer hitch. Class I trailer hitches are limited to 2 bikes maximum. Curt recommends the use of a stabilization strap, # 18050, for all...

  • What Advantages Does a Powered Taillight Converter Offer over a Factory Harness
  • This system draws power directly from the battery which means it will support more lights on the trailer and it since it is using a separate power source it will not damage the vehicle light circuits in case of a short or excessive power draw. If you are using a trailer with more than just two tail lights and two side markers, this would probably be a good upgrade. If you are towing a small boat or personal watercraft, you may also want to use something like this as a short is more likely...

  • Why Would Plug-N-Tow (R) Short Proof Powered Taillight Converter Fail
  • Trailer shorts often times take out the converter boxes like the 46365 that you have. Most likely something shorted out and damaged it. The boxes are designed to fail like this though as a way to protect the vehicle wiring. Basically you would will to go over your trailer wiring looking for any shorts from cut or exposed wire, fix as necessary and then replace the converter.

  • Will a Hopkins Trailer Wiring Harness 46255 or 46365 Fit a 2002 Mazda Protege5
  • You could use either wiring harness, # 46365 or # 46255 on your 2002 Mazda Protege5. The difference is that the 46365 is a newer design with added circuit protection. They will both install the same way. You will need to use a circuit tester like # ALL640595 to test the vehicle tail light wiring to install these harnesses. On the harness there is a red wire with a butt connector that connects to the positive battery terminal via the fuse and fuse holder included. The white wire is ground,...

  • Trailer Wiring Harness for a 2013 Hyundai Sonata Hybrid
  • I checked with the manufacturers we carry and there is an option from Hopkins, # 46365. But this is a hardwire wiring harness and not a plug and play type of harness. This means you will have to test the vehicle wiring with a circuit tester such as # 3808 and then splice in the harness wires accordingly. You will want to consult your vehicle owners manual for information on towing with the Sonata. Many hybrids are not rated for towing and the hitches for them should be used only for...

  • I checked with Hopkins and they show # 46255 or # 46365 as the hardwire options for your 2004 Jeep Liberty.

  • Ground Wire Problems With 7-way Adapter On 2008 E350 Econoline Van

The ground connection at the vehicle is especially important because it must travel through the connector to the trailer frame. The connector on the trailer should be secured to a clean surface on the trailer frame and each taillight assembly must be grounded either through the mounting bolts or a separate wire from the taillight to the trailer frame.
