I could tell immediately this was a far superior cable to the one I had before. Built solid and when I tested it with the receiving end I heard a nice click knowing it was securely seated in place. The previous cable did not do this. 938734

Wiring harness is great, but BE CAREFUL: All the colors may not match up with what you have on your vehicle and trailer. Fortunately, as an electrician, I like to ohm the pigtails first to verify which wire goes where...glad I did. I would recommend and by this product again. "3 stars" because not everyone has the tools to verify which wire goes where, but they could connect color to color if that was the case. 922963

Good unit. As long as it isn't cold. Then the wiring gets extremely stiff. This isn't rated for cold flexibility, but I'm still withholding a star for it's lack of cold weather flexibility. I ended up buying a different pig tail that was rated for cold weather. 913391

Excellent thick covering for the wires inside. Wires themselves are good quality too. The plug is durable and not cheap feeling. Overall the cable/wire system is very solid and I’m really pleased with the quality. I used this on my trailer project. (Bought this one, RV standard, and should have bought the other kind - not a big deal, just have to match colors up properly. I’m still very happy with it.) 814583

I recently ordered this power cord for my travel trailer as my original cord became corroded and difficult to engage into the tow vehicle plug. It is not hard to tell the replacement cord is far superior to the original, fit and finish is great and slides into the receptacle with ease. Installation was a no-brainer, took me about an hour. When I originally ordered the cord, I ordered a cord 1 foot shorter than the original. I gave etrailer (Rebecca) a quick call and she cancelled the original order and got me the cord I needed with no delay -- Thank you Rebecca. 806060

Everything arrived in perfect order and exactly as I was hoping for. I will get these parts installed on our horse trailer soon and will attach pictures once completed. I also will be ordering a few more items for my new pop up once I get it home and see exactly what it needs. Looking forward to fixing that up as well. 801307

Ask the Experts about this Hopkins Wiring

  • Will 7-Way Connector Charge Auxiliary Trailer Battery
    The yellow wire on the Hopkins 7-Way RV Style Connector with Molded Cable # H20046 will not be able to charge an on-board battery, it should really be used for reverse lights. To charge the auxiliary battery on your trailer the best option is to use a battery charger such as the CTEK MULTI US 3300 12-Volt Universal Battery Charger # CTEK56353 which you would plug into a standard outlet. You can maintain that charge when driving by running # 10-1-1 wire along with 40 amp circuit breaker...

  • Adding 5-Way Harness to 2018 Toyota Highlander With 4-Flat

  • Gauge Wire to Use When Wiring Up Brake Assemblies
    10 gauge wire like our part # 10-1-1 (sold by foot) is the correct gauge to use for trailer brake output circuits as it can deliver the amperage needed to activate the brakes properly.

  • How To Wire In a 7-way to Replace a Boat Trailer 5-Way Flat
    You definitely could install the 7-Way Molded Trailer Wire Connector # H20046 in place of the 5-way that is installed on your trailer currently. The colors wouldn't match up exactly. White would go to white, you would run both brown wires to the single green wire of the 7-way. Yellow of your trailer would go to the red wire of the 7-way, and green of the trailer wiring would go to brown of the 7-way. Now without knowing where the red wires of the 5-way go it's hard to say for certain....

  • Is Replacement Trailer Side 7-Way Connector # H20046 Male or Female
    The Hopkins 7-Way connector, part # H20046, is a male connector. The trailer side is the male end because it inserts into the vehicle side. This is somewhat misleading because usually a male connector has prongs and vehicle side trailer connectors have the prongs even though it is a female connector. I've never seen a vehicle with a male trailer connector. Likewise with a female on a trailer. Take a look at the pictures I've attached and see if they match the type of setup you have....

  • Wiring Trailer Reverse Lights Using Spectro Trailer Wiring Junction Box # 38656
    Power for your trailer's backup lights needs to come from the tow vehicle's reverse light circuit. You will need to choose one of the available circuit posts on the Spectro Junction Box # 38656 as the one you'll use for the reverse light circuit. Usually this would be the Auxiliary post at the far end of the box opposite the ground. Please refer to the linked photo. It does not matter what color wire you use to wire the trailer (although using the conventional colors does help keep...

  • What Gauge Wire Should be Used to Wire Trailer Brakes
    That's a very good question, we tend to be extra cautious and say to use 10 gauge wire because that would be more than enough. When you get into longer trailers that will end up using a lot of wire the heavier gauge wire becomes more necessary. On a smaller trailer with a single axle of brakes 12 gauge wire would probably be enough. But for a longer tandem axle trailer I would recommend you run 10 gauge wire to all the assemblies just to minimize the amount of resistance that would be on...

  • Equipping 2004 GMC Sierra to Maintain Battery on Enclosed Trailer
    What you are wanting to do is actually pretty simple. The 12-Volt accessory circuit on your 7-way can be used to tend or maintain your battery on your trailer, but the circuit does not have sufficient amperage to charge a battery that has been completely discharged. Using a battery isolating solenoid like part # TR118665 would be advisable. This will prevent the battery on the tow vehicle from being discharged by disabling the 12-volt accessory circuit from the 7-way once the ignition...

  • Replacement 7-Way and Junction Box for 5th Wheel Trailer with Non-Functioning Brakes
    Since you have confirmed that your 5th wheel's brakes do not work even when connected to a different tow vehicle you will want to focus on the trailer for your troubleshooting. There are simple troubleshooting steps you can take to isolate the problem on the trailer. First, I suggest checking the condition of the 7-way plug. Sometimes corrosion can develop INSIDE the plug housing where it is all but impossible to detect. Normal exposure to the elements can cause this. Since your brake...

  • Recommendations For Re-Wiring Horse Trailer With Brakes
    Since you said you have a 7-way blade connector on your Silverado I would start with the 7-Way Molded Trailer Wire Connector, part # H20046. This is an 8 ft long harness with the 7-way trailer connector. If you need a shorter harness you can check out part # H20044 which is a 6 ft long harness with the connector. You will want a circuit tester like part # 40376 to make sure you match the wiring on the trailer side connector to the functions on the vehicle connector. I then recommend...

  • Can 7-Way Molded Trailer Wire Connector Connect to Roadmaster 6-Way # RM-910030-6
    Yes, the terminals of the RoadMaster 6-Way connector and socket part # RM-910030-6 are compatible with 10 gauge wire like what comes with the # H20046. The center pin of the 6-way is the 12 volt accessory circuit and the ground is the circuit in the 2:00 position as you look into the opening of the connector.

  • How to Make 6-Way Square to 7-Way Adapter
    To make a 7-way to 6-way square adapter will require you to get the part # 37995 to use the 6-way end and then wire up a 7-way to it like part # H20043. This will give you the adapter you would need since there isn't one already pre-made.

  • Does 7-Way Molded Trailer Wire Connector Have a Reverse Light Function
    Yes, the center pin on trailer side wiring harness # H20046 is for reverse lights on the trailer. For this particular harness it is the yellow wire. But it will only work if the center pin is functional on your 2012 Toyota Tacoma. If you have the factory installed 7-Way on the Tacoma then it should be active.

  • Recommended Wiring Harness for Rewiring a 26 Foot Gooseneck Stock Trailer
    It sounds like you are wanting to rewire your gooseneck trailer with a 7-way connector. To do this I recommend the 7-way connector # H20046, the bonded 16 gauge 4 wire per foot # 16-4B-1 for the trailer and the 10 gauge jacketed wire # 10-2-1 for the brakes and ground. Often times, people will run the wires from a 7-way such as yours to a junction box like part # 38656. From there, they will run the standard wire colors to the trailer lights, brakes and battery.

    The Hopkins 7-Way RV Style Connector with Molded Cable - Trailer End - 8' Long - RV Standard # H20046 will connect to your 6 wires function for function. Many trailers will not have the reverse light function, so it is likely that you have a ground yet it is simply a different color wire on your trailer.

  • How is Length of 7-Way Connector Lead Determined for Wiring Up Trailer
    The method you described would be a great way to determine what length to cut the # H20046. That way you would end up with enough wire that it wouldn't come unplugged when making a tight turn. Securing the wire up and out of the way is a smart option as well so that the weight of the cable would not want to pull it out of the connector and so that it doesn't get caught on anything.

  • Replacing Damaged 7-Way on Horse Trailer
    There's more than one accepted way to wire a 7-way, but the most common uses the green wire for right turn/brake, yellow wire for left turn/brake, brown for running lamps, blue for brake output black for 12-volt accessory power to the trailer, white for ground and purple for the reverse light circuit. Because wire colors can vary so greatly, we typically tell folks to wire by function, not by color. An alternative color code is yellow wire for auxiliary or reverse lights, green for running...

  • Troubleshooting Tekonsha P3 Brake Controller 90195 Overload Issue
    Since your local technician tested your Pathfinder's 7-way and found it to have a functional trailer brake circuit, AND since your new trailer behaved properly when connected to another tow vehicle, the issue I suspect you might have is an intermittent short in the trailer wiring. If the trailer is not brand new there could be corrosive build-up on or even inside the 7-way plug. Water can over time migrate into even a sealed/molded 7-way plug like # H20046 and cause adjacent circuits...

For a 7-way with 6 ft of molded wire you need part # H20044, and for the connector with 4 ft of molded wiring you need part # H20043. for a connector with a coiled wire I recommend the WesBarg 7-Way, RV-Style Connector, part # WG54006-043.

    You will need to wire the 7-Way Molded Trailer Wire Connector, # H20046, for function rather than by color. Since the trailer side needs to be replaced, you will need to trace the wires back to see which wire does which function. An easier option would be to test the connector you have, before replacing it, to see which wire color matches which function on the trailer side of the connector. Using a circuit tester, like # PTW2993, test the trailer side wires for: right turn and stop,...

  • Is a Battery Isolator Needed when Adding a Battery to a Trailer
    First, the 12 volt circuit from a trailer connector, and most factory alternators on vehicles, are not able to charge up a trailer mounted battery. What they will do is provide a maintenance charge and keep the trailer battery at its current charge level. A battery isolator will only send power back when the vehicle is running. This will help to keep from draining the vehicle battery. Or you could just disconnect the trailer from the tow vehicle when you stop for long periods of time....
