• 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.

• 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...

• 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.

• Solution for Towing a Coleman Camper with a 6-Way Square Connector with a Tow Vehicle with 7-Way
  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. I attached a chart that shows the colors of the wires and where...

• 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.

• Which Pin On 7-Way Connector Is The Ground
  The ground pin of a trailer side 7-way connector like the 7-Way Molded Trailer Wire Connector, 4' Long # H20043 you were looking at is the 5 o'clock position as shown in the included picture. For the vehicle side of the 7-way connector it would be the 7 o'clock position. I included pictures of both of the wiring positions for both sides of the 7-way connector and a video of the # H20043 for you to take a look at.

• 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 some of the...

• 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 the...

• How To Replace 7-Way Trailer Connector On Trailer with 5 Wires
  In order to install a 7-way trailer connector like the 7-Way Molded Trailer Wire Connector part # H20043 on a trailer with five wires, we need to know what those wires do. I can almost guarantee what four of them are; left stop/turn, right stop/turn, running lights, and ground. If the trailer has brakes then the last wire is for the brake output. If the trailer has an on-board battery then the wire is for the battery charge line. If the trailer has backup lights or an electric actuator...

• Troubleshooting Trailer Battery Backfeeding Into Truck Lights
  From what I can tell of your explanation, it sounds like the trailer battery is backfeeding into the truck, causing this issue. The only way I can think of that this would happen is that your 7-way like the 7-Way Molded Trailer Wire Connector # H20043 is not pinned correctly. I'm not sure which trailer connector you purchased from us so the best I can offer is for you to ensure the 7-way is wired correctly by function instead of by matching colors. I have added links to some help articles...

• Installing New 7-Way Trailer Connector on Dump Trailer With Different Wire Colors
  That is correct. As long as you make sure the functions match you won't have a problem. For example, a connector like the # H20043 uses a red wire for the left turn/stop which follows the RV Standard. To connect to the traditional SAE you would hook it onto the yellow wire which is also left turn/stop just like you said. Since the trailer is marked with RV standard wiring it is probably safe to assume the colors correspond with the following: Green: Tail/running lights Yellow: Reverse...

• Best Way to Connect Truck Camper 6-Way Pin to Truck 7-Way Connector
  It sounds like you have a Lance truck bed camper. Lance came out with their own specialized 6-Pin which can be frustrating as it doesn't match with any standard connectors and there aren't any adapters so we typically recommend just replacing it with a standard 7-Way like the Hopkins # H20043. This way the camper wiring matches easier with other connectors. All you have to do is cut off the Lance connector and match the functions on the 7-Way and you'll be good to go! I'm attaching an...

• Short Circuit in Trailer Connector Melted Wiring and Causes Trailer Brakes to Lock Up
  On a 7-Way trailer connector there should not be a 24 volt wire. But wires could come loose and make contact with other wires inside the connector and cause a short which is what sounds like happened. I recommend replacing the trailer side 7-Way with # H20043 which also has a 4-foot lead of wires in case the problem exists further back in the wiring. On this harness the white wire is ground, red is left turn signal/brake light, brown is right turn/brake light, green is tail lights, blue...

• Trailer Wiring Solution for a 1996 Forest River Pop Up with 6-Way Square
  We have a solution for you, but we do not carry the adapter you are looking for. A much easier solution would be to cut off the connector on your trailer and replace it with a 7-way like part # H20043 since that would make your trailer easier to connect to your vehicle and other vehicles. You would need to determine the functions of each of the wires on your trailer first. You can do this by running a jumper cable to each of the wires from a 12 volt battery. Once you do that you can then...

  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 Can I Get Tail Lights on a Trailer with an Australian 7-Way Harness on My Trailer?
  The best route for having brake lights, turn signals, and running lights on your trailer with an Australian 7-way is to use the Vehicle to Vehicle Tail Light Converter # 118158. With this system, this will split up the wiring signals for your brake lights and turn signals on the left and right side. For installation, you will have to splice into your current wiring setup. I went ahead and attached a photo that shows the a 4-way wiring setup to give you a good idea of the process.

• What is Needed to Clean 7-Way
  There isn't a specific tool to clean the 7-way connectors, but some simple household items will work. For example, use some pipe cleaner and white vinegar and that should get the job done. If you do have to replace your 7-way on the trailer side you can use # H20043. And to avoid corrosion and dirt build-up in your connectors I very highly recommend always using Dielectric Grease for Electrical Connectors # 11755.
