Video of Curt 5th Wheel/Gooseneck Custom Wiring Harness w/ 7-Pole Connector - 10' Long
Videos are provided as a guide only. Refer to manufacturer installation instructions and specs for complete information.
Speaker 1: Today on our 2016 Ram 2500, we're going to be taking a look at and showing you how to install the Curt 5th Wheel or Gooseneck Custom Wiring Harness, part number C56000. Here's what our 5th wheel and gooseneck wiring looks like when it's fully installed. It's going to give us a 7-way socket at the back of our truck, so that way when we're towing with a 5th wheel or a gooseneck, we'll have our connector right here.It does come with a spring-loaded weatherproof door to keep out some of the moisture and help corrosion from building up on the inside of our socket. Now, not only is this going to give you all the required lights on your trailer such as your stoplights, clearance lights, and your turn signals, now it's also going to give you all the functions of a 7-way, including your brake controller. That is, if the factory 7-way on your vehicle is connected that way as well.Now the way we're going to install this is there's going to be a T connector that goes between our factory 7-way and the back of our bumper, and it's going to run up to here. Our harness does come with a 10 foot lead, so there's plenty of wire to run it and most applications where you put it in the back of the bed here.One of the nice features of our harness here is that it does come preinstalled with wire alum across the entire length of our wire, helping protect it from the elements or anything else.
Now that we've gone over some of the features and benefits, let's show you how easy it is to get installed.To begin our installation, we're going to need to find a spot to mount our 7-way plug. Now right here just on the inside of our bed towards the bottom seems like a good spot to mount it. Now we're going to need a 2 1/8 hole saw, and I just want to mention you want to be extremely careful when you start drilling, because once you start drilling you don't want to push too hard and go through too far to the outside of the bed.Now if this happened where you go through the first piece and there is a secondary support piece back there, we are going to have to drill through that as well. It's never a good idea to leave bare metal exposed on your vehicle, so I'm going to come back with some clear spray paint and spray paint the inside of this so that I can prevent some of the rust.Now we'll going to have a couple different options of how we get everything routed, but this end of the plug is going to end up right here, and this is going to need to go towards the back of our bumper. So we can either feed this down or we can take this end and come from underneath and feed it up through.
Now we'll go ahead and try to feed this down. You may have a little bit of trouble getting it through the hole, in which case we might have to go through the bottom. It looks like we can feed it through, so we're going to feed this, letting it fall all the way down.Now we before we connect it I'm going to put a little dielectric grease on my connection points, and that's just going to help keep out some of the moisture and help any of the corrosion buildup from happening. Just line up the tabs on our socket and plug, make sure everything locks into place. Now we can get ready to mount our plug right here.Now on our kit they do provide us with some self-tapping screws, so I'm going to take my self-taping screws, I'm going to secure my 7-way to the side of my bed.
I'm going to repeat that for all the remaining holes. So here's my 7-way that I dropped down. Now we're going to get this over to where our factory 7-way and our bumper is, so I'm just going to go over my frame here and route it towards the center of my truck. Here's where our factory 7-way is and if we come to this tab right here, we're going to push down and it should release the plug, allow us to access the socket on the back.I'm going to take a little bit more dielectric grease and put it into my connections. Now we can take our 7-way that we routed over here and plug it in to the vehicle socket, make sure that it locks, put a little bit more dielectric grease on the other end of our connector.
We can plug it back into our factory socket. Make sure it locks. Now all we have to do is tidy up all the wires. We'll just put a few zip ties, just keep everything secure, and also so it's not hanging down.Now I got my tester plugged up. Now with an extra set of hands I'm going to have them run up to the front to make sure all my lights are working and everything's working properly. So we can see that our clearance lights are working. Now if we have the left turn signal, please. Now the right turn signal. Now the brakes. Now finally the brakes and both turn signals. Looks like everything's running good. Now while we're here we might as well check our brake controller. Now if we look up at the top, if our extra set of hands hit the manual override to make sure that the power's going through, we can see that's working as well. Now we're ready to hit the road.That will finish up our look at the Curt 5th Wheel or Gooseneck Custom Wiring Harness, part number C56000 on our 2016 Ram 2500.

Product fit and performs perfectly on my GMC Sierra 647258
Very pleased with etrailer.com. All product information and reviews help make decision very easy. Very quick delivery and installation instructions are very easy to follow. Purchased 5th wheel hitch and custom wiring extension for my 2014 F250. 390373
Thanks for the follow up. I’ve enjoyed the products ease of installation and use. I easily hook up my 5th wheel camper by myself and have had no issues. Great products!
Mike S - 06/09/2018Wow! I ordered the products on Monday night (after 7p.m CDT) and I had the items on my property Friday afternoon! Great shipping speed which is really order processing and getting the product out so UPS could deliver it. I ordered the Curt A16, custom rails for my 2015 F250 and the Curt harness. All three items took me about 4 hours to install--mostly by myself. The install was easy, but I needed the tools that were listed in the videos--WHICH is one of the reasons I ordered from etrailer.com --the videos for installation and product research, not to mention free shipping. I researched the products for several months before ordering, no other site compares to etrailer.com...the educational product videos really helped me make a decision. Tools that are needed or at least will help make this quicker--Hydraulic jack, safety jacks, impact wrench, Electric drill, 2 1/8" hole saw for the harness plate mount, 9/16" bit, tape measure, hammer, long straight screwdriver for tapping spacers into place, some good light, and an uninterrupted afternoon in your garage. I am so glad I ordered from etrailer.com and would recommend all of these above products. THANK YOU!!! 371329
I haven't installed it yet, however, I cut the inside bed wall in preparation for a spray-in bed liner before installing. It looks just like the picture and description, arrived undamaged and ready for install. Great installation instructions! 286124
Still using and I really like the hitch and other items I purchased a year ago. After installing the Curt fifth wheel hitch, Ive used it several times and I will be using it a bunch over rbe next several weeks. Easy to maintain and use.
Les - 11/01/2017etrailer is the man 564601
The cord made the electrical part of installing my new fith wheel hitch very easy just plug in the connections and your done . 294808
The products have worked flawlessly no problems and thank you for checking back with me its nice when a company cares about there costumers. Next time I need any trailer products I will definitely be contacting etrailer.
Kevin L - 10/23/2017This product makes it so simple to add a Fifth wheel plug into the bed. Installation takes maybe 20-30 minutes. I installed mine on the column at the tailgate so it is out of the way (less likely to get damaged by other cargo). The only issue I experienced with install was that due to the small opening in that column (from under the vehicle), I had to remove the gray wire cover and then reinstall it after feeding the wire harness up into the column. (This was minor) Would definitely recommend this as it is simply "plug n play" with no cutting of wires or crimping needed. 289606
Product and location has worked perfectly and keeps on doing so. Great product!
Richard P - 08/31/2017Works as advertised. This wiring harness is being used to connect from a 2019 Ram 3500 8' box to a slide in truck camper. I ran this harness across and then up through and over the drivers side wheel well to have the connector available in front of the wheel well and behind the fuel door. Plenty of space in the area between the box wall and truck wall without interfering with any of the fuel or breather lines. 726118
Easy install perfect fitment 713469
The website couldn’t be easier. I typed in my vehicle and it showed me all items I needed for a fifth wheel hitch. 714708
Purchased this hitch, install kit, and wiring harness for a new to me 2015 F-250. After watching the installation video and reviewing the included instructions the install went smoothly. The only deviation from the instructions was instead of using a unibit to drill the 9/16" holes in the bed I used a Rotobroach hole cutter(the holes are cleaner and the bit does not drift. I hooked in to my fifth wheel for the first time on Saturday. 699221
Quick delivery and reasonably priced. I will purchase from etrailer again. 661166
Product arrived and installed as presented. All aspects was as described. 639432
Great wire kit, easy install. Instructions were excellent and easy to fallow. No troubles at all. 637506
Awesome works great with my 5th wheel and gooseneck horse trailer. 633300
Product was as advertised, very clear instructions and installation was a breeze, as always etrailers customer service is top notch. 617052
I am so glad that I purchased this extension and relocation unit. I installed this myself outside in my driveway in about an hour. Everything was there that I needed (other than the hole saw) to install. I haven't had a single electrical issue with this plug or my factory plug since installed. Looks great in the bed also. 589980
As described, priced good, what we wanted, chose fast shipping and paid for it and got it when we needed it. Thank you 557914
Damn good cause it’s made in America.
LT - 08/25/2019Works great 515342
Erica B you are the greatest , your customer support was ABOVE & BEYOND you did more for me than most company's ever do . Keep up the good work . Only if we could get the manufactures [CURT] to do what you did. Thanks once again Erica you made my day and then some . Tom 501432
Great product!!!! Use the video they have to install. Hooked right up, took me less then 30mins to install and test. First time doing it with no help except video. Love you guys. Wish you guys had an account I could get to save my profile. Will shop more from you guys. 499513
This was a great product, works exactly as advertised. A couple of things to note for install on a newer (2011-2016) model truck: 1. The Diesel Exhaust Fluid reservoir/pump makes the driver-side part of the install a pain in the butt. Particularly drilling the holes in the bed for the tow-chain loops. You have to drill from the underside of the bed, however there is almost no clearance between the DEF setup and the bed. I had to use an air grinder (90 deg) with a shorty bit to drill a small pilot hole on the front hole, and then measure the distance and drill the rear hole from the top down (blind). 2. The frame clamp (u-bolt) on the driver-side needs to be smashed a bit with a hammer to get it into position to fully clamp down. Last thing (not necessarily about late model Ford), it is almost impossible to get a torque wrench in to tighten the adapter plates to the actual hitch. I just put a 1/2" drive flex head on my air-gun and went to town. Other than these things it installed pretty well...could have used a lift. I'm a curt fan! 485057
The instructions were excellent and it fits exactly as expected. Be nice if the was a version with 2-3 feet of cord versus 10ft. 483249
Fast shipping, great price! 478806
We received a complete order and on time 465609
Very nice product, worth every cent, very clean tap in harness, with no destroying factory one to wire in another, thanks a lot George- travis 462012
Do not like anything to do with automotive wiring so I purchased this item because it appeared to be just plug and play with no cutting or splicing wires. It is just that, plug and play and it was done. Unplugged 7 point connector attached to bumper and plugged in the new wiring harness. One other plug was unplugged and wiring harness 2nd plug was plugged in. Route wiring loom along along factory wiring loom inside frame close to the front of my 2004 F 250 super Duty 8ft truck bed. Drilled hole and connected harness and plug so my slide in camper electrical will plug into this trailer plug. Screws to mount to inside of truck bed are stainless steel which is great to protect against rust. I also brushed Rustoleum paint inside the hole I cut so there was no bare metal surfaces exposed. 10ft wiring loom was the right choice to get plug up near the front of my 8ft bed. 461403
Worked perfectly on our RAM 3500. However, the wiring/plug behind the trailer plug on the factory hitch is in some tight quarters. Getting a hand in there to unplug the factory connector was so tough that I decided to lower the spare tire on the winch about a foot or so to gain a little more access. Then it was a breeze to unplug the factory connector and simply snap in the Curt harness connectors. A 2 1/8" hole saw is needed to install the 7-way where you want it in the sidewall of the truck bed, but that went smoothly enough. A nice neat installation which allows our slide-in camper to get power and still leave the connections on the trailer hitch available for towing if necessary. 460850
Perfect fit. Easy install. 460255
This extender along with the Curt nQ25 Hitch are awesome perfect fit for truck etrailer was wonderful to order from shipping was perfect double boxed and packed well , communications were great its a super heavy duty hitch and price was fair I would not hesitate to buy from which I am sure I and friends will as they all have trucks and trailers 452899
Very good quality and. It got to me super fast! I never give reviews, but this time I was very impressed! 448865
Great quality and service! 442178

Pleased with the unit and installed with no issues 421296
had an issue with a wiring harness so sent it back to see if it was bad. Was shipped out a new one very quickly. thx doug 416629
Worked great. 411228
Awesome product fit the truck just like it should and very easy to install keeps me from scratching the tailgate with a wire over the back of the truck easy to reach when hooking up trailer 409570
Quick and simple installation!! 394759
Installed in minutes thanks to the videos by etrailer. The harness is probably long enough to put in front of the rear tire, like I've seen in some trucks. I put it between the rear tire and tailgate. If you can't drop your tailgate it can be tough to plug it in. I've seen cheaper ones, but plenty of length on this harness, which can be coiled and strapped easily out of the way. 387124
Quality product. Connectors snapped right into place. Plenty of cable length. I tested with my trailer after installing and it worked perfectly. 364611
Paid someone to install it, worked great after install. Just don't forget to unplug before you unhitch like I did! 351880
Fit the truck perfectly. The length was excessive. Would order the 7 foot for a 6.5 Foot bed. 348737
Couldn't get any easier to install 348617
I'm a huge fan of completing wiring projects with no "hacking" into harnesses. This harness is plug and play. When I finished installing it, the underside of the truck looks like it came from the factory. Job done 348534
I havent thought about it for a year. I can give no higher praise for a product.it does its job very well.
Jim - 03/04/2018Easy to install, self explanatory. Worked excellent! 342684
If the connector that has to pass thru the bed was a 2" cutout instead of a 2 1/8" cutout as the addition of the notch on the connector mandated, the installation could have been much easier. 326928
This product worked out great. The kit came with everything needed to install the in box connector except the hole drill. Nice clean look and quality wires and connectors. Thank you etrailer! 318481
Customer service for product selection and order entry were excellent and focused on my interests and needs. The hitch, custom installation kit, and harness were shipped very quickly and arrived sooner than expected. Everything arrived in excellent condition. Assembly and installation instructions were very clear and specific, and I was able to assemble and install everything with no problems and in a very reasonable amount of time. Total cost was roughly half of what it would have been if I had purchased the products and had them installed by a dealer. I am very satisfied with my experience dealing with etrailer.com, and would highly recommend them to anyone shopping for towing products. 293516
Awesome. The hitch has worked great. Very, Very happy with the purchase,delivery, installation which I did myself, and performance of the product.Thanks again,Ill be sure to refer anyone who needs products you offer to you.
Peter C - 10/23/2017this is the only way to go quick and easy installed it I 30 to 45 min 289677
easy to install worked like a charm 289178
