Its worth the money, no cutting any wires just drill 1 hole and be done



by:

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

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



by:

Nicely constructed wiring is robust. Only thing I change is the plastic cover and flap to metal.



by:
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:

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:

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:
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!!

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!

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:

Great product (Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole ). Great service.
Easy installation

Super fast shipping
Great customer service
Will definitely recommend to friends and family

Amy & Adam are very pleasant to deal with and professional



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:

The CURT wiring harness appears to be correct, but I have not installed it yet. I will provide more details after I install this harness. I think that the 7 foot length will be just right for the truck, but I will know more once I install it.



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:

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:

The pins on this didn’t like to make contact with my trailer connector. The trailer is brand new. I had to do some tweaking to get it to work right.



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:
Dodge Ram Pickup

Plug and play gooseneck wiring addition for my Dodge Ram. Well made.



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:
2005 Dodge Ram Pickup

I have a 05 ram 2500 and the gooseneck harness was easy to install and plugged right into the factory harness. Thank you.



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:

Good quality product easy to install. Just purchased a new fifth wheel trailer and brought it home yesterday.

  • Help Finding Square Connector to Install Curt 5th Wheel/Gooseneck Custom Wiring Harness on 2008 Ram
    The square connectors you are looking for on your 2008 Dodge Ram to install the # C56071 are on the harness that runs to the 7-way of your truck. Easiest way to find it is to trace the harness from the back of the 7-way to the front of the truck. You'll encounter the square connector pretty easily from there. If you fast forward to the 1:40 mark of the attached video link You'll see exactly where to find it as well.

    Hello Cris, The Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector - 7' Long # C56071 is designed to pigtail into your 1996 Dodges wiring behind your trailer connector. I would look behind the 3 pin and 4 pin to see how it is hooked up, you should see the connectors that the # C56071 will plug into. I attached a picture of the connectors.

  • Adding 7-Way And 4-Flat To 2006 Didge 2500 5.9L Diesel
    Hello Steve, thanks for getting in touch. Your best option here will be to replace the current 7-way plug. Assuming your 7-way is from the factory, you can swap it out with the Multi-Plug T-One Connector Assembly for 7-Way & 4 Pole Trailer Connector # 20135. This will plug in to the factory connector (pictured below) and provide you with both a 7-way and a 4 flat, allowing you access to both at once. As far as an extension for the boat trailer you can use a 4-flat harness like part #...

  • Recommended Plug and Play 7-Way Harness for a 2006 Dodge Ram w/a In Bed Camper
    Hey Scott. If your 2006 Dodge Ram 3500 came with a 7-way from the factory, you can install the Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector item # C56071. This harness puts a 7-way connector in the bed of your truck and allows you to keep the one on your bumper. It will plug directly into the factory wiring a foot or so back from your 7-way connector. Does your 2006 Dodge Ram 3500 have a factory 7-way connector? You can add this information and any other questions...

    Hello Robert. We do offer a gooseneck hitch that will work on your 2003 Ram 3500 short bed. For that I recommend the B&W Turnoverball Underbed Gooseneck Trailer Hitch # BWGNRK1313. The frame brackets will not interfere with your air bag brackets. Every air bag kit made for the 2003 Ram 3500 was made to be compatible with an in-bed gooseneck hitch, so you will have no issues there. You may also want the Curt Gooseneck Wiring Harness # C56071. This will allow you to add a 7-way connection...

  • Troubleshooting Curt 56071 Not Working With 2024 Ram Truck
    Hey Landry! The reason your Curt # C56071 doesn't work with your 2024 Ram is because it was designed for older models ranging from 1998-2009. For your 2024 you need the # C56070 which will work with the 1500, 2500, and 3500. If you have any other questions don't hesitate to reach out in the comments below.

    If you have no trailer wiring presently on your truck I recommend the Tow Ready T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part # 118329 first. This simply plugs into the existing wiring on your truck along the frame rail as shown in the attached video. You will then need part # ETBC7 to plug into the 4-way connector and with additional wiring will give you the 7-way you need. There is no plug and play wiring harness available for your Ram.

    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...

  • 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.

This hitch will allow you to tow a gooseneck trailer via the included gooseneck ball, but since Mega Cab trucks all have a 6-1/2' bed you will likely need the 4" Offset Ball # BWGNXA4085 to give you more turning clearance.

  • Adding a 7-Way Trailer Connector to the Bed of a 1997 Ford F-350 for a 5th Wheel Trailer
    We do have the parts needed to add a 7-Way trailer connector to the bed of your 1997 Ford F-350. To determine exactly what you will need we have to first look at what type of trailer connector, if any, is on your truck. If it came with a factory installed 7-Way at the bumper check to see if you can unplug a round connector from the back of the 7-Way socket. There may be some locking tabs that you have to disengage to disconnect it. If it is set up that way and the connector is round you...

    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 # 54701-007.

  • 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 Hopkins harness # HM42137.

  • 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.
