I bought the adapter based on advice. The 7-Pole Round Trailer Connector Adapter # PK12727 is NOT the same as the Lance plug. Adapter is good quality and arrived quickly bu unfortunately would not work for my Lance camper factory plug. 570748


Comments
If the camper has a 7-way round pin, youll need an adapter like part PK12727.

Ask the Experts about this Curt Custom Fit Vehicle Wiring

  • 7-Way Trailer Harness Extension That is 2 Feet Long
    For a 7-Way extension like the Curt # C56080 that you referenced that's just over 2 feet long we have the TorkLift Wiring Harness Extension # TLW6024. This will extend the 7-Way on your truck by 28 inches. I have attached a short video review that you can check out as well.

  • Truck Bed Camper 7-Way Recommendation for 2018 Ford F-450
    Sounds like you are looking for a 7-way to install in the bed of your truck for the 7-way of your camper to attach to. For that you'd want the Tow Ready part # 20110-010 which will install easily and give you the 7-way you are needing.

  • 7-Way Extension To Avoid Connection Ripping Out Of Socket
    The Curt Universal 7-Way Extension # C56080 will give you an additional 7 feet of extension to ensure your connection will not rip out of the socket. Extension plugs into your existing 7-way, RV-style connector to route functionality from the rear of your vehicle to your trailer.

  • Typical Uses for Curt 7-Foot Universal 7-Way Extension Cable C56080
    Curt part # C56080 is a 7-foot extension cable in the 7-way RV blade style connector format. The male plug end is just like what many trailers with electric brakes are equipped with; and the female socket end is the same as a 7-way socket that would be found on a vehicle that is set up for towing such a trailer. This item carries trailer lighting, trailer braking power and 12V auxiliary power signals from a vehicle to a trailer. This part works as an extension cable for any application...

  • What Gauge of Wires Are Used in the Curt Universal 7-Way Extension 56080
    The spoke with Curt about the Curt Universal 5th Wheel/Gooseneck 7-Way Extension part # C56080 and they informed me that the green (right turn/stop light), yellow (left turn/stop light), brown (running light), and purple (reverse light/lockout) wires are 14 gauge. The blue (brake output), black (12 volt power) and white (gound) wires are 12 gauge. I am sure the boot on the back of the 7-Way Super Sealed Connector part # 50-87-009 could be trimmed down but you would be opening yourself...

  • Length of Curt Universal 5th Wheel/Gooseneck 7-Way Extension # C56080
    The Curt Universal 5th Wheel/Gooseneck 7-Way Extension # C56080 referenced in your question features an end to end length of 7 feet. This extension will plug right into your existing 7-Way RV-style connector so you can route it to the bed of your truck for simple hookup with your trailer. I have attached a short video demonstration on this product that you can also check out.

  • Can the Curt 7-Way Extension be Used with a PowerMax Converter to Power Trailer
    Instead of using the Curt Extension # C56080 I recommend using the Bargman # 50-87-009. This comes with an extra 2' of wiring and it already has the female end disconnected so less work on your part! Then the correct wires that you need are the black and white wires. Black is for power and white is for ground. Be sure to follow the instructions for your PowerMax during the installation.

  • Does the Curt 7-way Extension part # C56080 Carry a Circuit that Could Charge a Trailer Battery
    If you have a 7-way on your tow vehicle that has the 12 volt accessory circuit active and a 7-way on your trailer that has the 12 volt circuit run to the positive side of the battery on your trailer then yes, the Curt 7-way Extension part # C56080, when plugged in between your trailer and tow vehicle will put a maintenance charge on your trailer battery. If you are looking for something to charge a dead trailer battery you would need a battery charger that would plug into a wall outlet...

  • Will 7-Way Trailer Connector Extension Charge a Trailer Battery
    The Curt Universal 7-Way Extension, part # C56080, plugs into your truck's existing 7-way and moves it inside the truck bed. This makes it easier to hook up a fifth wheel or gooseneck trailer. The 12 volt pin on your existing 7-way will provide power to your trailer's battery through the extension, however it isn't going to charge a battery. The current from a 7-way connector only maintains the charge on a battery.

  • Will Curt Universal 5th Wheel/Gooseneck 7-Way Extension # C56080 Fit a 2008 GMC Sierra
    You can use Curt Universal 5th Wheel/Gooseneck 7-Way Extension # C56080 provided that your 2008 GMC Sierra has a functioning 7-Way trailer connector. The wire gauge is appropriate for the functions the 7-Way was designed for (trailers, campers, and so on).

  • What Trucks Will Curt Universal 5th Wheel/Gooseneck Extension # C56080 Fit
    The Curt 5th Wheel/Gooseneck 7-Way Extension # C56080 referenced in your question is a universal product that will plug directly to an existing 7-Way RV-style connector. Unlike other fifth-wheel wiring harnesses that plug in line at the back of a factory 7-Way, this will go right to the actual 7-Way connector, so it will work with any truck that already has a 7-Way installed. I have attached a short video demonstration on this product that you can also check out.

  • Wiring Lance Slide In Camper to Work with In-Bed Trailer Connector on 2019 ford F250
    Since the 7-way round pin plug is obsolete, your best bet would be to replace the connector on your camper with the common 7-way blade style connector. You'd remove the existing plug on your slide in camper, and replace it with # 54-77-003. You could then use an extension like # C56080 to reach the connector rearward of the wheel well.

  • 7-Way Extension for Towing Food Truck with 2003 Ford Expedition
    Thanks for the picture of the trailer wiring connector you have. Based on that you are in need of a 7-way blade extension like the part # C56080 for a 7 foot long extension or part # HM20049 for an 8 foot long extension. Or if you are looking for something shorter you'd want the part # TLW6024 which is 24 inches long.

  • Hitch Extender Compatible With Truck Bed Camper and Trailer Towing 19 Foot Aluminum Fishing Boat
    For your 2004 Chevy Silverado 2500HD, the Curt Trailer Hitch Receiver - Class V Commercial Duty - 2-1/2" # C15703 is a confirmed fit. This hitch will allow you to use the Titan Hitch Box Extension for 2-1/2" Trailer Hitches, 41" - 48" Long # RP45018. This will give you a towing ability of 4,000 lbs at full length so your aluminum 19 foot fishing boat, motor, and trailer should be well under the rated capacity.

  • Recommended Wiring for Semi Tractor to Tow Gooseneck Trailer
    The wiring on a semi is not normally the same as a standard RV or Gooseneck trailer. You will need to use a couple different harnesses to get what you are looking for. I recommend the ZCI Circuit Protected Vehicle Wiring Harness w/ 4-Pole Flat Trailer Connector and Installation Kit # 119250KIT which will clip onto your truck wiring to capture signal. Then you will need to hardwire a brake controller like # 90195 and use the 7-way brake controller kit # ETBC7 to make the wiring compatible...

  • 5th Wheel/Gooseneck Trailer Wiring Harness for a 1997 Ford F-250 Heavy Duty
    Gooseneck/5th Wheel Trailer wiring harness # 40167 fits 2002 - 2004 Ford F-250 and F-350 Super Dutys with factory 7-way connectors. It will not fit a 1997 Ford F-250 heavy duty. There are currently no in-line harnesses that will fit. But what you can use is # 20027 or # C56080. Either of these will plug into the existing 7-Way and the long cable allow you to put the 7-Way in the truck bed. These harness just do not plug in line at the backs of the 7-Way like the other harnesses.

  • Best Way to Add Length to 5th Wheel Trailer 7-Way Wiring Harness in 2012 Ford F-250
    In the long run you will be glad you have a long bed pickup since 5th wheel towing is much easier with the extra turning clearance you get from a long bed truck like your F-250. I have a suggestion that will not require you to remove the existing wiring harness, nor to have to drill another hole in the bed side. All you need is a 7-way extension cable like the 7-foot Curt # C56080. All you need to do is insert the trailer's male plug into the female socket and then connect the extension's...

  • Will Curt E16 5th Wheel Hitch and Universal Install Kit Fit a 1997 Dodge Ram 1500 Short Bed
    Curt 5th wheel hitch and universal installation kit # C16116 will fit your 1997 Dodge Ram. But since you have a short bed I recommend the slider version, # C16616, so you will have more clearance when making turns while towing. If your truck has the factory 7-Way connector at the bumper you can add an in-bed harness # C56071, that will plug in line with the factory 7-Way. This allows you to have 2 functioning 7-Ways without the need of an extension. If you want to use an extension though...

  • Trailer Wiring Extension to Allow Utility Trailer Plug to Reach Truck Bed Connector
    We can definitely help you! If your trailer and truck connectors are RV-style 7-way blade types we offer extensions in various lengths. For example, if you need several feet of additional length we offer the Curt Universal 5th Wheel/Gooseneck 7-Way Extension # C56080 which is 7-feet long. If a shorter extension will suffice you might use the 28-inch TorkLift # TLW6028, 36-inch # TLW6036 or 48-inch # TLW6048. If either your truck or trailer use different connectors (the linked...

  • Curt Echo Wireless Brake Controller Compatibility with 2016 Thor Palazzo and Trailer Side Mount
    The Curt Echo Mobile Trailer Brake Controller - Wireless # C51180 can be hard mounted to the trailer but it cannot have any flop or movement of the unit because it is inertia based and needs to be able to find the consistent point to monitor movement from. The direction of the controller isn't an issue so if mounted to the side frame at an angle is okay. You can use an extension like the Curt Universal 5th Wheel/Gooseneck 7-Way Extension - 7' Long # C56080 which can be shortened or coiled...

We have some ready-made 7-Way extensions that you can use such as # 20027 or # C56080 which are 7 feet long. We have a shorter option, # TLW6021, which is 21 inches long.

  • Adding a Brake Controller to a 1995 Chevrolet 3500 to Tow a Gooseneck Trailer with Electric Brakes
    First, your 1995 Chevy 3500 is going to need a 7-Way trailer connector if it doesn't have one already. To add a 7-Way you will first need to have a 4-Way flat connector if the truck does not already have one. Use # 118315 to add a 4-Way. Then to add a 7-Way use # ETBC7. This will provide all of the wiring needed to install a brake controller. I have included some links that will help explain the ETBC7 installation. Once the 7-Way is installed you can use an extension, # C56080, to...

    If your 1997 Dodge Ram 1500 has no type of factory trailer wiring at all then you'll need first to install a 4-pole harness like # 118329. This is a simple plug-in harness that installs at your tail light assemblies with no cutting or splicing of wires. You'll then convert that to a 7-way blade type RV socket using our # ETBC7 trailer brake controller installation kit. This kit includes a 7-way that plugs in to the 4-pole. The extra circuits will be connected using the supplied wiring,...

  • Recommended 7-Way Trailer Connector Extension for a 2014 Ram 2500
    What I recommend is the Curt universal extension # C56080. It will plug directly into your existing 7-way connector and provide you a length of 7 feet. If you only need a few more inches of play, the adapter # C57003 you referenced will work fine. I included the installation instructions for you too.

  • 7-way Round to 7-Way flat Adapter Recommendation
    For a 7-way round to 7-way flat adapter you would want the part # PK12-724. For a 7-way extension that would give you 7 feet of extension you would want the part # C56080. If by chance your tractor has separate taillight wiring, meaning that the turn signals and brake lights run on separate pins, you will need to add a converter, like the Tow Ready, # 119130. Just cut off the 4 way end and wire it into this adapter. I have attached a picture which illustrates this. In order to...

It is rated for different capacities based on the length used, so you will need to make sure your trailer and weight distribution system work within its rated capacities.
