• Wire Color Coding of Bargman 7-Way Super Sealed Vehicle Side Trailer Connector
  
• The Bargman 7-Way Super Sealed Connector # 50-87-004 you received actually uses the standard wire coloring for camping trailers. The color code is labeled on the front of the 7-way's cap to try and make it easier. We always recommend to connect wires by function instead of by color since there are more than one standard and often times those are deviated from completely. I've attached a picture of an RV standard 7-way that's common on camping trailers and is what the # 50-87-004 uses.

• 7-way Recommendation to Replace a 6-Way
  
• I would recommend you cut off the 6-way you have at the rear of your truck and then install a # 50-87-004 in it's place. I attached a couple wiring diagrams for the two styles of connectors so that you would know how to wire up the new 7-way with the wires from the 6-way.

• Recommended 4-Pole to 7-Pole Wiring on Vehicle
  
• I recommend the Universal Installation Kit for Trailer Brake Controller, # ETBC7, to convert your 4-way round into a 7-way connector. This kit will allow you to splice in your current 4-way wiring and includes the wiring, mount, circuit breakers, and other hardware to run an electric brake controller for trailer brakes. To splice in, you will have to remove the 4-way flat from this connector and use butt connectors like # DW05745-10 to pair your current trailer connector wires. This...

• Standard And traditional Wiring Configurations For 7-Way Trailer Connectors
  
• There are traditional and standard wiring configurations and that can be frustrating when working with electrical connectors. We try to always remind customers to check wiring for function and not to rely on the color of the wires for that reason. The standard connectors are typically wired for fifth wheel and travel trailers and the traditional is typically used for utility and cargo trailers. I have attached a couple drawings that show the wiring configurations for standard, traditional,...

• Brake Controller Recommendation for a Trailer with Electric Over Hydraulic Brakes
  
• I have a solution for you, but the Prodigy RF Brake controller part # 90250 is not compatible with electric over hydraulic brakes. Instead I would recommend the Prodigy P2 Brake Controller part # 90885 as this controller is compatible with EOH brakes. The Demco Hydraulic Brake Line Kit # DM5425 would work fine with AL-Ko calipers. The Adapter part # F77R would work for converting the 7-way round he has on his trailer. A better solution would be to not use an adapter and match both...

• Options for Extending 7-Way Vehicle-Side Connector while Towing Tent Trailer and Bike Rack
  
• I have a solution for you, but the Curt 7-Way Trailer Adpater for VW, Audi, and Porsch Towing Trailer with LED Lights # C57003 is designed for that specific application and would not work well if you do not have one of those manufactures as a tow vehicle. For a plug and play option, you can use the TorkLift Wiring Harness Extension # TLW6021. This harness will offer much more than the 3 inch extension you are needing, so the excess on the extension will need to be kept off the ground...

• Compatibility of Bargman # 54-77-003 7-Way Connector With # 50-87-004 Vehicle End Socket
  
• You can indeed install the Bargman 7-way connector # 54-77-003 onto the # 50-87-004 Sealed connector. However, there is a connector loop like this that's already constructed, part # 20027. If you're wanting to use this item to install a 7-way connector in your truck bed for a fifth wheel, we offer T-Connectors like # 41157 that would plug inline with the truck wiring harness that feeds the 7-way connector on the bumper. Some of these are vehicle specific, so if you'd be interested in...

• How to Wire an Electric Winch on the Front or Rear of a Vehicle or on a Trailer
  
• You will want to either use a trailer mounted battery or wire the winch directly to the vehicle battery. This is because the vehicle wiring and wiring to a trailer connector cannot handle the amperage draw required by a winch. The other issue is that vehicle alternators cannot push back enough amperage over that great of a distance to power the winch properly. But there are some solutions. Take a look at the help article I have linked to the right. It covers different ways that you can...

• 2 Foot Long 6-Way Vehicle to 7-Way Trailer Connector Adapter
  
• A 6-Way to 7-Way adapter is not all that common but we have a few. But they are not 2 feet long. The closest we have is # 47435 which end to end is around 12 inches but the wiring part between the 6 and 7-Ways is 6-1/2 inches long. What you could do is use # 50-87-004 which is 4 feet long but can be trimmed down to 2 feet. You would just need to add a trailer side 6-Way, # PK11604.

• Availability of 10-Foot-Long Replacement 7-Way Vehicle Side Connector Like # 50-87-004
  
• We do not offer a 10-foot replacement sealed vehicle 7-way like the part you referenced, part # 50-87-004, but we do have an easy and cost-effective way for you to construct the harness you need. You can use Deka Jacketed 7-Wire cable, part # DW04914-1, which is offered by the foot, along with a connector, Pollak # PK12-707E (please see linked video). The wire gauge in the Deka cable is 12-gauge for all but the white wire, which is 10-gauge. You can use Deka butt connectors # DW05745-10...

• Wiring Adapter 7-Pole Round to 7-Way Blade with 4 Feet of Cable Between Connectors
  
• The Pollak Trailer Connector Adapter # PK12-724 that you referenced offers 7-1/2 inches between the 2 connectors, and is 14-1/2 inches long overall. This is the longest pre-wired 7-Pole round to 7-Way blade adapter that we offer. You can use individual connectors to wire together an adapter that will have as much room between the connectors as you need. I recommend using the Bargman 7-Way Super Sealed Connector with 4 Foot Cable # 50-87-004. This 7-Way blade vehicle-end connector is...

• Installing Vehicle Side Trailer Connector to Trailer Deep Cycle Battery to Power 12V Interior Lights
  
• The Hopkins Endurance Quick-Install 7-Way Trailer Connector with Universal Pigtail Harness - Vehicle End # HM47210 can be connected directly to your trailer battery. You will run the Red wire to the positive terminal on your battery, but the white ground wire will connect to your trailer frame, just like the negative terminal of your battery does. You just want to make sure that connection to your frame is free of rust or corrosion for a bare metal to metal connection. That will give...

• Replacement 7-Way Recommendation for a 2009 Ford F-150
  
• You are going to need to replace the 7-way with a standard one since what you have is a non-standard connector that we don't offer anything for. For a 7-way that comes with a plug and lead you would want the part # 50-87-004. Then for a 7-way to 5-way adapter you would need the part # A75TB.

• Recommended Mounting Bracket For 7-Way Vehicle Side Connector
  
• The mounting bracket I recommend to use with the # 50-87-004 7-way connector is part # 18138. This bracket comes with the mounting screws needed to secure the 7-way connector. If you do not want to drill holes in the vehicle to mount the bracket, you can take a look at one of our no-drill brackets. The no-drill brackets feature a hose clamp that can secure the bracket to a trailer hitch so you do not have to drill holes to mount the connector. For a short bracket you would order...

• Will Bargman 7-Way Socket # 50-87-004 Fit Bargman 7-Way Plug
  
• The Bargman Silicone 7-Way Plug 54006-010 that you have is a standard style 7-way plug that the # 50-87-004 that you referenced is designed to fit. I can't say we've seen this issue before so would it be possible for you to send me pictures of the connectors you have on both your truck and trailer?

• Availability of 7-Way Connector Shorter than 7 Feet
  
• I have some options for you, but unfortunately I could not find a 7-Way 5th wheel/gooseneck wiring Connector Loop shorter than the Draw-Tite # 20027. I recommend simply looping up any excess and wrapping a zip tie # DW05727-25 around it to adjust it to a shorter length. If your tow vehicle has a 7-way at the bumper that uses a US-Style car connector, another option is to install a 5th Wheel/Gooseneck Harness in line by using the Draw-Tite # 20110. This will provide you with a 7-way connection...
