We purchased a new 5th wheel so had to upgrade the wiring harness. This harness was a simple plug and play and works great with our new 5th wheel. My husband leaves it plugged into his wire harness under the bumper and has it run up between the tailgate and the back of the bed and just leaves it in his truck. We do have a cover on our truck so it is not exposed to the elements. I would highly recommend this wiring harness to anyone. 401191

Decent hitch but etrailer again shorted me parts. I contacted etrailer and told them the parts that were shorted. They did not take responsibility and blamed it on the manufacture. This is now the second time I have had problems with etrailer in the last 6 months. Now my customer is pissed that the hitch will take an additional 1 week for the missing parts to be shipped. I am done with etrailer. 402260

This extension cord is what I've been looking for. Product came to post office very quickly. Bought this for our 5th wheel and to move electrical hookup from bumper to bed without cutting more holes in bed. 5th wheel is still under wraps for the winter and I haven't installed yet. Will be a couple of months before actual use. The cord is heavy duty construction 466293

We bought a new travel trailer and the cord was loose and a little short on tight turns. This has solved that problem and it has done what I thought it was going to do. When I initially was ordering I had questions about which product would suit my needs and all of my questions were answered. I would not hesitate to buy another product. 115049

Just what I was looking for! Our fifth wheel has a short cable on hitch and when getting in tight turns or steep angles would come unhooked. This product allowed me to mount in bed and took care of issues. Quick delivery so we'll be ready for the next trip! 519891

All three of the products we bought had a good solid snug fit, insuring a good connect. We have them all connected and have used them for a few days with no problems. I am glad we found your site and it easy to locate the products/adaptors that we needed. 199263

Exactly what I needed and had been looking for. My trailer wiring wasn't long enough for my new truck and I need an extension. Thought about making one myself but this was so much better. I won't hesitate to look on your web site for any future needs. 413705

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.

Do you have a question about this Custom Fit Vehicle Wiring?


  • 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...

  • 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...

  • 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. I then recommend using wiring extension # C56080 which can be cut down from...

  • Recommend Hitch Extender for 2017 Ram 2500 and 2006 Pioneer Trailer with 6400 lb GVWR
  • The Curt Hitch Extension and Reducer for 2-1/2" Trailer Hitches - 24" to 34" Long # C45048 will allow you to leave your tailgate down and still tow a trailer. 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. You will also want the Curt Universal 5th Wheel/Gooseneck 7-Way Extension - 7' Long # C56080 which can be trimmed to length if desired.

  • Wiring Between RV and Flat Towed Vehicle Pulls Out When Turning
  • If the distance is too far between the connectors on the motor home and vehicle then a straight cable would not help much unless it was a longer cable. You can try moving the location of the cable so there is enough slack to make turns without it pulling loose. Another option is to extend the 7-Way using something like # C56080. You probably would not need the full 7 feet of length this harness has but it would definitely be enough to prevent the cable from pulling out on turns. Currently,...

  • 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.

  • 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.

  • How to Add Gooseneck Wiring to 1997 Dodge Ram 1500 Without Factory Wiring Harness
  • 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,...

  • 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...

  • 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.

  • 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...

  • 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...

  • 7-Way Blade Style Extension for 1991 Jayco Trailer
  • I do have a 7-Way extension that you can use but # HM47085 will not work. You will need # C56080. It may be more length than you need at 7 feet long but it is a true 7-Way extension. The extra length could be held together with wire ties or you could cut it to the length needed and reattach the wires to the connector.

  • 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).

  • Trailer Wiring Extension for a Tall 2018 Ram 2500 Power Wagon Towing a Rental Trailer
  • We do have various trailer wiring extensions you could use. If the rental trailer has a 7-Way blade style connector you could use an extension such as # C56080. Granted this one is 7 feet long but it costs less than shorter extensions and who knows when the additional length might come in handy. If the trailer takes a 4-Way you could use 12 inch extension # HM48145. Need more length? There is a 48 inch 4-Way extension too # HM47115.

  • What do I need to Install a 7-Way Connector in the Bed of a 2000 Ford F-350 Super Duty
  • What you will need for your 2000 Ford F-350 is a 4-pole hardwire kit # 18252, universal installation kit # ETBC7 and universal 5th wheel/gooseneck 7-way extension # C56080. Install the # ETBC7 (provides 7-way connector) and # 18252 (provides 4-way flat) at the rear of your truck. The Curt 5th wheel/gooseneck 7-way extension # C56080 will install in the location of your choice in the truck bed. I have provide a few links to help guide the installation.

  • To add a 7-Way trailer connector to the bed of your 1999 GMC truck you have some options. First, if the truck came with a factory 7-Way then you can just use # C56080 which will plug into the 7-Way at the rear of the truck. If your truck does not have a 7-Way then you would first need to install one. To do this you can use # ETBC7. For this to install you would need to have a 4-Way flat trailer connector at the back of the truck. If you do not then you can install one, # 118315, and...

  • 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...

  • 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...

  • 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...

  • 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.

  • Availability of an RV Style 7-Way to 7-Way Extension
  • If you want to use # WG54006-043 then you just need the vehicle end, such as # PK12-707E, since it already has the trailer end on it. 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. And we have a 10 foot long model # TLW6510.
