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



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 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.

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.

Great product (Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole ). Great service.
Easy installation
great instructions with pictures
Super fast shipping

Will definitely recommend to friends and family

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:
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:
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

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:

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 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:

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:
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:
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:

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



by:

Easy...great wiring solution to connect existing tow package wiring to accommodate camper or fifth wheel.



by:

awesome product. Plug and play no problems at all. Took about 20 minutes with my 4.5 year old putting in the screws for me and drilling the holes. Great father son project.

  • 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 #...

  • 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.

  • Recommended Below the Bed Gooseneck Hitch for a 1998 Dodge Ram 2500 with a 8 Foot Bed
    The hideaway gooseneck hitch I recommend for your 1998 Dodge Ram 2500 is the B & W # BWGNRK1394. It has a 30,000-lb gross towing weight and 7,500-lb tongue weight. The hitch ball can be engaged or disengaged from inside your 8 foot bed. The custom fit wiring you will need is part # C56071. It is a RV-style connector that you mount in your 1998 Dodge Ram 2500 to hookup of your 5th-wheel or gooseneck trailer If you don't have some already, I recommend using Loctite Threadlocker # LT37420...

    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...

  • 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...

  • 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.

  • 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 # 54701-007.

    I have bad news and good news for you. The bad news is that you won't be able to install typical 5th wheel rails in the bed of your 2007 Dodge Ram Pickup because the brackets from the B&W gooseneck hitch use the same mounting locations. The good news is that we have adapters that you can use to get around this.

I also suggest you select a 16K-rated hitch because at this weight rating your hitch will include additional features often not found on lower-rated hitches - such as a cushioned 360-degree pivoting head like that on Curt sliding hitch # C16521. This hitch has a 4000-lb tongue weight rating and has 12-inches of slider travel to make...
