Still working as it should at 1 year

Worked as decribed, and was plug and play. Throw the hardware they provide out and replace with S.S. hardware.

Good quality looking part not yet insta lled




by:

I like the simplicity of install with the plug and play wiring harness but the trailer plug itself where are you plug in your trailer is lacking, when trailer plugged in fit is very sloppy and trailer loses connection often, which is very sketchy when towing my 40 foot, 20,000 pound fifth wheel that you rely on the trailer brakes for stopping




by:

Did not fit the truck I bought it for


Comments
I will have our customer service team reach out to you. This harness is intended to be used with 1995 - 2008 Dodge Ram Pickups that came with the factory 7-way.
-- Etrailer Expert Jenny N - 01/06/2022

2006 Dodge Ram Pickup

This product worked at first. Then, my lights on my trailer did not work when they were plugged in as usual. This product is an in bed wiring connector so you don't have to hang your goose-neck light wiring over the tail gate. I traced the problem to the Curt harness. I have since unplugged the Curt harness and hooked up the OEM light harness on the truck. And, subsequently have been hanging my lights over the tailgate and no problems with the trailer lights. (It was the Curt harness not the trailer lights).




by:

Installation was easy. My only disappointment was the light duty 7 pin plug. The prongs of the plug are thin and not very robust. Nothing like my factory plug.




by:
2007 Dodge Ram Pickup

Parts just arrived. All in excellent condition. The greatest part is the excellent installation instruction videos available on line. I am beginning the installation of 5th wheel hitch, this wiring harness and a Curt trailer brake controller. The video for the controller showed me where to find the OEM plug which was taped up behind the wiring harness bundle under the dash that would have been impossible to find otherwise. Other companies may have the same parts but etrailer also educates. Absolutely, far and away the best!!




by:

Was a very easy install, only hiccup was no right hand signal or brake light. Called trailer's and they clued me on the right side was the brown wire. Worked the ends of the brown wire and found the end that plugs to the truck power was loose, with some pushing it clicked in and now works great. Would definitely recommend this product and etrailer. Bought this to bring my 5th wheel plug into the bed.




by:
Dodge Ram Pickup

We received the 5th Wheel / Gooseneck harness to work with our existing Dodge Ram 3500 trailer hitch wiring group with no problems. The assembly was installed and tested within 30 minutes and everything worked as it was supposed to. I felt the product and service I received was extremely well done and I would recommend eTrailer and there products to anyone. Thanks again - problem solved!




by:

Simple and easy to install very happy with the product




by:
Dodge

The 7 pole connector wire harness worked great. It was heavy duty and well built. The only thing that could have been better was the plugs. I have a 1999 Dodge truck and the plugs fit perfect however they do not "Clip" in. I had to tape them. Other than that I am pleased.




by:
1999 Dodge Ram Pickup

Great product (Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole ). Great service.
Easy installation
great instructions with pictures
Super fast shipping
Great customer service
Will definitely recommend to friends and family




by:
2001 Dodge Ram Pickup

Very happy with this. I read people saying it was too long but on my 01 short bed dodge it was perfect length to put it in the tailgate post. Wire, plugs and heat shrink all good quality. Only thing really needed is s drill, self tapper bit and a 2-1/8 hole saw. Installation time for me was less than an hour.




by:
2007 Dodge Ram Pickup

Installed in less than hour. Perfect fit. Only negative, too much cable depending on installation location., would be nice to offer a long and short version. Certainly not a functional issue. Recommend this product. Etrailer service was excellent, very much appreciate the videos and accompanying documentation.




by:
1998 Dodge Ram Pickup

This harness makes for a quick and easy installation, I actually have two of these hooked up on my truck, one for the receiver and one ran into the sidewall of the bed for the goose neck. Good quality build with every thing sealed as it should be.




by:
2008 Dodge Ram Pickup

Awesome product. Took me longer to find my hole saw in the garage than it did to instal the harness. Took less than 20 minutes




by:

This product is exactly what it says it is any body can do this on there truck in less than a hour I am very pleased with this product my customer was very happy with it he ain't never used a bed plug before and had bumper plug for his gooseneck he was pleased




by:
2008 Dodge Ram Pickup

I was happy with the transaction with etrailer. The website was very helpful in finding what I needed. The product was received ahead of the committed date. The only problem was with the packaging. Some of the boxes were pretty beat-up and the parts were scratched with the finish damaged. That was a little disappointing.




by:
2008 Ram 2500

I have not had a chance to install this product yet I have only compared the two harness for likeness, but it looks like it will be a direct plug and play into my 2008 dodge 2500 just as stated. The wires used look to be of good quality and it’s all nicely wrapped and taped in wire loom.




by:
2008 Dodge Ram Pickup

From what I can tell it seems to be a good product. The install was pretty straight forward and easy. The only complaint I have is that one of the plugs would not lock in good. I just put a zip tie around it to ensure connection wouldn't be lost during road conditions.




by:

Great product quick easy installation. Highly recommend this product.




by:

The shipping estimate was perfect and delivered on time. Haven’t had the opportunity to tow with it yet, but the hitch came with minor scratches and small dents due to shipping. Definitely would still recommend.




by:
2007 Dodge Ram Pickup

Easy install and very good customer service. Fast shipping!!!




by:
2014 Dodge Ram Pickup

The harness is missed wired for a ram. one of the green and yellow are incorrect. This is the second one in two years. One was 2014 and the other 2000 , both rams

  • After Installing a CURT Fifth Wheel Extension Harness Will Both 7-Ways Work
    If you install the CURT Fifth Wheel / Gooseneck Extension Harness # C56071 that you referenced you will able able to use the 7-way at the rear of your vehicle and the one inside the truckbed without any problems. Basically, they both are active and either can be used without problems. I attached installation instructions for this product for you to check out also.

  • Fifth Wheel Trailer Wiring Recommendation for a 2001 Dodge Ram 2500
    For trailer wiring that would allow you to install a 7-way in the bed of your 2001 Dodge Ram 2500 you would want the part # C56071 that has been confirmed as a fit. This will plug in-line with the 7-way you have at the rear of your truck and then will provide you with a 7-way to install in the wheel well.

  • Will the Draw-Tite Fifth Wheel and Gooseneck Wiring Harness # 20110 Fit on a 2006 Dodge 3500
    The Draw-Tite Fifth Wheel and Gooseneck Wiring Harness # 20110 that you referenced is not a confirmed fit for your 2006 Dodge 3500 Megacab. The specified part for your truck is Curt Harness # C56071 which installs by simply plugging in to your Ram's existing factory 7-way wiring. Your factory 7-way will remain active after installation. I have linked the written instructions as well as an installation video.

  • Replacement 7-Way Bumper and Truck Bed Connectors for 1996 Dodge Ram 3500
    The Curt 7-pole 5th wheel wiring harness you referenced, part # C56071, and the Hopkins replacement 7-way # 42125 will work together in your 1996 Dodge Ram 3500. They will connect together behind the bumper and give you 7-way connectors at both the bumper and in the truck bed. Part # 42125 is compatible with your 1996 Ram 3500.

  • Connecting Aftermarket Brake Controller to Curt 5th Wheel Harness on 1997 Dodge Ram 3500
    Since you have the factory tow package you should be able to simply plug the aftermarket brake controller into the factory connector. The connector is usually located under the dash near the emergency brake pedal. If you have a 4 way connector at the rear of your Ram you will want to add a 7 way. You will need the Hopkins Adapter 4-Pole to 7-Pole and 4-Pole # 37185 to complete your wiring. The blue brake wire will not run all the way back to the 4-pole at the rear; it stops at the connector...

    We do indeed offer a plug and play 5th wheel harness for your 1996 Dodge Ram 2500. I'd recommend the Curt # C56071. I've linked to a product description video featuring the Curt # C56071 wiring harness/7-way in-bed trailer connector.

  • Gooseneck Trailer Wiring Harness for 1995 Dodge Ram 2500
    Due to the age of the truck, neither Curt nor Tow Ready have a listing for the vehicle, but there are only two possibilities. The wiring harness that plugs into the rear of your OEM 7-way should have either a rectangular or a round connector on it. If it is rectangular, use the # C56071 you mentioned. If instead, your 7-way uses a round connector, use part # C56070. I have provided a photo showing both styles of connectors side-by-side. I have linked you to install details.

    Yes we do, check out the Curt 5th Wheel/Gooseneck Custom Wiring Harness # C56071. This is a very similar harness as the Curt 5th Wheel/Gooseneck Harness # C56070 that you referenced except it is confirmed to fit your 2006 Dodge Ram 2500.

  • Is 7 Foot Long 5th Wheel Trailer Wiring Harness Long Enough for an 8 Foot Truck Bed
    The 7 foot long Curt fifth wheel wiring harness your purhcased, part # C56071, should fit just fine in your truck even with the 8 foot bed. However, you probably will only be able to reach the rear part of the bed behind the wheel wells. There is the 10 foot version, part # C56001, which will likely increase your options as to where in the bed you can install it due to the added length.

  • Troubleshooting New 7-Way Where All Circuits Arent Active
    Sounds like you have blown some fuses or relays on your 2005 Dodge Ram and that is why only certain circuits work after the install of the # C56071. Check the owners manual and look for all of the towing related fuses and replace as necessary. You might try checking all of the circuits with a circuit tester liker part # PTW2993 on the 7-way to make sure that the problem is on the vehicle side of the equation. It could be that the 7-way is functioning properly and the light assemblies...

  • Where Does Curt 7-Way Trailer Connector C56071 Plug Into on a 1998 Dodge Ram
    If your 1998 Dodge Ram came with a factory installed 7-Way trailer connector then you can use Curt harness # C56071. You would follow the factory connector's wiring harness forward under the vehicle to where it plugs in. The connector should be rectangular like those on the Curt harness. If they are a different shape then you would need to use # 20023 which requires hardwiring into the vehicle wiring. You would need a circuit tester such as # 40376 or a meter if you have one to determine...

  • 5th Wheel/Gooseneck In-Bed Trailer Wiring for a 2006 Dodge Ram 2500
    Take a look at the back of the trailer connector on your 2006 Dodge Ram 2500. If the connecter that plugs into the back of it is square/rectangular then # C56071 will fit. All of the 5th wheel/gooseneck in-bed harnesses have square plugs for this truck. Take a look at the video I have linked showing installation of a similar harness. If the connector that plugs into the back is round then you would likely need # 54701-003.

  • Is Curt Q20 Sliding 5th Wheel Hitch Compatible With 8 Foot Truck Bed?
    The Curt Q20 sliding 5th Wheel Hitch # C16536 can absolutely be used in your long bed Ram. The sliding base isn't needed for a long bed, so it is a little heavier to install but will have no other issues. If you want new base legs for an easier installation you can use the Replacement Base Legs for Curt Q20 5th Wheel Trailer Hitch # C16904. This swap out will make a 93 lb difference as well as give you a more solid hitch because there won't be as many moving parts. You may also want...

Don't forget the Curt 5th Wheel/Gooseneck Custom Wiring Harness part # C56071 to complete your setup.

  • Gooseneck/5th Wheel Trailer Wiring for the Bed of a 2006 Dodge Ram 3500
    I recommend going with a gooseneck wiring harness that has a 90 degree bend. The reason for this is because it makes installation easier because on some trucks there isn't a lot of space between the inner and outer bed side walls. Having an extra ground wire is not a bad thing. It helps ensure that the harness has a good ground connection. With that said you can't really go wrong with Bargman harness # 51-97-411. I have linked a video to the right that shows how it installs. For a low-cost...

  • 2007 Ram Pickup Brakes Lock Up When Gooseneck Cattle Trailer is Connected to 7-Way
    The brakes on your 2007 Ram Pickup should not activate when a trailer is connected. Since your truck's brakes are hydraulic there is no way for an electrically-operated trailer brake controller to interact with the truck's brakes. If it is the brakes on your trailer that are locking up when connected to the truck, then this could mean that the pin configuration for the trailer connector does not match the wiring on the trailer. It sounds like the auxiliary 12V trailer power and electric...

  • Replacement 7-Way Trailer Connector for Curt Wiring Harness 56071
    Yes, you can get a replacement 7-Way receptacle only to fit in place of the one on # C56071. If you wanted a Curt brand you could use # C57101 which is a little fancier with its backup alarm and 4-Way flat built in. Or for something simpler, just a 7-Way, you could use # PK11893.

  • Recommended Curt Slider Hitch for 2004 Dodge Ram 2500
    The Curt A16 5th Wheel Trailer Hitch w/ R16 Slider part # C16521 is the perfect option for a 2004 Dodge Ram 2500 when used with the Curt Custom Fifth Wheel Installation Kit part # C16420-204 which makes for no-drilling into the frame. I personally love the A16 because it has a secure dual jaw system which limits movement and an easy to remove head which saves your back. I also recommend the Curt 5th Wheel/Gooseneck Custom Wiring Harness part # C56071 to complete your setup.

  • 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...

    The Curt E16 5th Wheel Trailer Hitch - Slide Bar Jaw - 16,000 lbs # C16115 would be a great replacement for your Husky 16K Easy Roll Hitch. They have identical capacities and both mount on industry standard rails. Since you are using a Reese Revolution rotating pin box you will need the Sidewinder Wedge for Curt E Series 5th Wheel Trailer Hitches item # C16991. This prevents your Revolution king pin from pivoting in your hitch. To make towing with a 5th wheel easier I recommend adding...

    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.

If you don't already have a 7-way trailer connector in your truck bed, you can install one using part # C56071.

  • Gooseneck Hitch and Installation Kit to Tow a Horse Trailer with a 1999 Dodge Ram 2500 Quad Cab
    For your 1999 Dodge 2500 Quad Cab, I'd recommend the B&W Turnover Ball gooseneck hitch, part # BWGNRK1394, which includes the 2-5/16 inch ball and the rails to mount the hitch to the truck frame. This hitch has a 30,000 pound capacity so as long as your horse trailer, fully loaded and ready to tow, does not exceed that, this hitch can handle the weight. You will need to consult your owners manual for the towing specifications for your vehicle. I have included a link to the installation...
