My horse trailer OEM unit was brittle and stiff, after just a few years. This new wire harness from etrailer fixed the problem and was easy to install. It is even a little longer then the OEM, so there is more more room for turning sharp corners. 783746

All is okay however the cord that I received measures 43" from end to end. In my situation It would sure have been nice to have extra instead of the piece being a bit short. Oh well, if I wouldn't have wrecked the original one it wouldn't be an issue. My bad. 733948

Product shipped super fast and arrived one day earlier than expected! Good quality product, too, only concern is that the white 10 ga wire is not finely stranded like the smaller wires. It is stranded to be sure, just the strands are fewer and larger than expected. It should still last a long time. 706072

Ask the Experts about this Hopkins Wiring

  • Is the Yellow Wire For the Reverse Lights On the 7-Way Molded Trailer Wire Connector H20043
    In regards to the 7-Way Molded Trailer Wire Connector part # H20043, the yellow wire is for the reverse light circuit yes. This should then align with the pin responsible for the reverse light circuit on your vehicle. The terminology used for "AUX" is the same as the reverse light circuit. Please note, if you are rewiring a trailer I highly recommend you use a junction box, the Trailer Wiring Junction Box part # 3375601101 to keep everything organized. We also have the Trailer Wiring...

  • Hooking Up New Hopkins 7-Way Connector Harness to Trailer Wiring
    The Hopkins trailer wiring harnesses like the model 20244 you have feature wire colors that differ a bit from standard setups so this is likely why the new plug isn't working when splicing the wires color to color. For your 20244 plug, which is similar to our Hopkins # H20043, the wire color functions are as follows: White - Ground Red - Left Turn and Brake Brown - Right Turn and Brake Green - Running Lights Blue - Brake Power Black - 12V Power Yellow - Aux In addition to...

  • Replacement for Damaged 7-Way Trailer Connector
    By damaged power cable, I assume you are referring to your trailer's 7-way being severed, and while there likely isn't going to be any electrical damage, you will need to replace the 7-way connector from the trailer. You didn't specify what was severed, but this is the most obvious culprit based on how they connect. For that you would be able to splice in a new connector, depending on the length you need: - 4 feet: 7-Way Molded Trailer Wire Connector # H20043 - 6 feet: Mighty Cord...

  • How to Determine Functions of Wires on Trailer and Recommended Trailer Connector
    I can help you determine which wires go to which functions for your trailer, though there is no way to determine this by color; the reason for that is functions are not determined by the color of the wire and there isn't a universal standard for this. So in order to determine the functions for your trailer use a separate 12 volt battery and run a jumper wire in order to apply power to the circuit which will tell you the functions of each wire. In regards to a plug, I recommend a...

  • Recommended Durable 7-way Trailer Connector Pigtail
    Hopkins does a very good job of constructing their molded 7-way trailer connector pigtails for durability, I can highly recommend part # H20044, which is 6 feet long. The best way to connect this to existing wiring is to use a junction box like # 3375601101. A junction box allows you to tidy up the connections, protect them from the elements and provides an easy way to change out the pigtail in the future should it become damaged again. One of the best ways to preserve the long term...

  • How to Power Utility Light In Trailer That Has 4-Way Connector
    You are on the right track. You will need to convert the 4-way to a 7-way so that you can tap into the 12 volt accessory circuit of the connector to power the utility light. For a 7-way with a 4 foot long section of wire you would want the part # H20043. Currently your interior light is ran to the running lights circuit of the 4-way wiring. You would need to run the light to the black wire of the new 7-way as that is for the 12 volt circuit. I attached a chart that shows how the 7-way...

  • Replacement Trailer 7-Way Recommendation for a 2002 Viking Legend Camper
    The trailer side 7-ways we offer like the part # H20043 all have blunt cut wires that you could splice into your trailer's wiring, but we do not have any 7-ways that have any connectors like what you described. You could still wire in the part # H20043 though. I attached a chart that details how this harness would typically get wired to a trailer. You can still send me a picture though and I will take a look at it.

  • Converting Trailer from 5-Way Connector to a 7-Way by Function
    I've linked a help article that will give you the common color coding but on your trailer I wouldn't go by it. Even if they are correct you just never know so I suggest testing it. To test it cut off the 5-way connector that's on there and connect each wire to a 12-volt power source and see what functions. Then use a 7-way connector like the Hopkins # H20043 and connect the function to the correct leads. Even the Hopkins does not use the traditional color coding. Instead it uses...

  • Availability of Wiring Adapter to Convert 12-Pin NATO Trailer Connector to 7-Way Blade Style
    We do not offer any adapters to convert a 12-pin military trailer connector to a 7-way RV-style plug like that on part # H20043 but we can help you gather the parts you'll need to wire in a new trailer plug to match that on your pickup. We can also offer you an easier alternative. To re-wire the trailer conector you'll need a wiring junction box # 38656, a trailer-side plug like the 4-foot # H20043 (or longer versions such as 6-foot # H20044 or 8-foot # H20046) and ring terminals like...

  • Color Code Functions of Hopkins 7-Way Trailer Wiring Harness
    The Hopkins # H20043 uses the following wire coloring: White Wire - Ground Red Wire - Left Turn and Brake Brown Wire - Right Turn and Brake Green Wire - Tail Lights Blue Wire - Brake Power Black Wire - 12 volt (hot lead) Yellow Wire - Aux. I recommend wiring your trailer by function and not color. If there is a circuit you don't need for any reason it doesn't have to be connected.

  • Will Hopkins 7-Way Molded Trailer Wire Connector Work With Trailer Connector On 2013 Toyota Tundra
    The Hopkins 7-Way Molded Trailer Wire Connector # H20043 is designed to be installed on a trailer and is compatible with the 7-way connector on your 2013 Tundra. When installing this harness I recommend using a wiring junction box like part # 38656. I have attached a link to an installation video for the junction box and also a helpful article on wiring you can check out. You want to make sure you note what the function is for each wire when you are installing the harness on your trailer.

  • Replacement 7-Way Recommendation for 7-Way on Trailer With Chipped Pin
    The chip in the picture you sent in is why your right turn and brake circuit aren't functioning. It's time to replace the 7-way connector. We have the part # H20043 which is a 4 foot long section. Or we have the part # H20046 which is an 8 foot long section. Or the best solution would be to use the 7-way upgrade kit part # e99011 which comes with a 7-way, a junction box to make installing the 7-way easier and then also the needed connectors and conduit. It basically is one part number...

    The connector you have on your trailer will need to be replaced as there isn't an adapter available for your setup. You will want to cut the 6-way round off of your trailer and replace it with a # H20043 by wiring it by function. You would want to apply 12 volts to each of the circuits on your trailer with a jumper wire and a car battery so that you can determine their function and then wire it to the # H20043 by function.

  • 7-Way Recommendation to Replace 4-Way on 5 by 8 Trailer
    You could easily replace the worn out 4-way on your trailer with a new 7-way. For that you would want the part # H20043. The white wire of this connector is for the ground circuit, the red wire would be for left turn/stop, the brown wire for right turn/stop, and the green wire is for the tail lights. The rest of the wires wouldn't be used. You will want to solder these connections or use butt connectors like part # DW05744-10.

  • Replacing a 6-Way Trailer Connector that Only Uses 4 Functions with a 7-Way
    To connect a 7-way trailer connector like # H20043 to your trailer you'll need to cut off the existing 6-way and then find out the function of each of the wire. They should be ground, running lights, left turn signal and brake, and right turn signal and brake. You'll need to trace each wire back to where it terminates or connect each wire to 12 volt power to find each function. Then connect the 7-way by function, I've attached a help article that gives the details on a 7-way connector....

  • Trailer 7-Way Connector and Wiring to Rewire a Trailer with Electric Brakes
    We have the Hopkins 7-Way Molded Trailer Wire Connector # H20043 which is 4 feet long. If it were me, I would use this with a junction box, like # 38656. For the wire you will want 10 gauge for the brakes, part # 10-1-1, and 12 gauge wire, part # 12-1-1, for lights. Both are sold by the foot. You will also need ring terminals # 44-5310A and butt connectors # DW05745-10. I've also attached a help article on trailer wiring that includes a wiring diagram you might find helpful.

  • Replacement 7-Way Recommendation for Trailer with 2 Round 4-Ways
    It's highly unusual for a trailer like yours to have two round 4-ways like what is in the picture you sent in. It's possible they would match the # PK11410 which is a female 4-way socket but I'd have no way of knowing how yours are wired since they are not standard. Best option I would have would be for you to cut off the 4-ways and wire them to a 7-way plug like part # H20043. To identify the wires of the connector you'd need to use a 12 volt jumper wire from a vehicle battery's positive...

  • Would a Boat Trailer Have a 7-Way Harness with only 5 Wires Ran to it
    It is very possible that your trailer has a 7-way harness installed on it and not all of the circuits are completed. For a 7-way and lead that is 4 feet long you would want the part # H20043. Then for a new junction box we have the # 38656. I attached an install video for you to check out as well.

  • How Should Utility Lights be Wired on a Trailer
    When you go to wire up the utility lights on your trailer the best way is to run the power wire to each light and then run the ground to either. Running them in series wouldn't be the best way since if one light goes out both go out like Christmas lights.

    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. Or you just cut off the 6-way and wire the # H20043 to the wiring in place of it.

  • Best 175/80-13 Trailer Tires for Highway Trips & Can Electric Brakes be Added to Boat Trailer
    Let's start with your tires and the best 175/80-13 tire is absolutely the radial tire, the Karrier ST175/80R13 Radial Trailer Tire - Load Range D # AM10210. The reason you want to use this tire over the Bias # AM1ST77 you mentioned is because radial tires are designed for on-road use while bias are designed for things like off-road and agricultural use.

    To charge your trailer battery when you look at the 7-way trailer-side connector the 11 o'clock pin will mate up to your 12V signal from your vehicle.

That black wire simply connects using 10 gauge butt connector like # DW05745-5 to 10 gauge wire sold by the foot # 10-1-1 which will connect to your trailer battery positive terminal.

  • Replacement for Factory 7-Way Trailer Connector on 2001 GMC Sierra 2500HD

For a trailer connector I recommend the Hopkins 7-Way RV Style Connector with Molded Cable # H20046 which is 8 feet long.
