See All Vehicle FitsVideo 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.
Today we're going to be taking a look at part number C56000. This is a CURT 5th wheel and gooseneck custom wiring harness. Offering your 7 pull connector. The product is going to fit multiple trucks so to see if this is a fit for your vehicle, you can use the vehicle fit guide located on our website at E-trailer.com. It's going to provide your 7-way blade style connector in your truck bed for hassle-free hookup of your 5th wheel and gooseneck trailers. The connector is designed to mount in the truck bed sidewall, tailgate post, or wheel well.
The benefit of this system is that it is still going to retain your factory 7-way connector at the rear of the truck, at the bumper, as long as it's already there. This does require that your truck has a factory tow package. This area right here, this part number, is going to plug into the factory wiring. Does not require any cutting or splicing, so it's a really easy installation process. Then you're going to have 10 feet of insulated wiring. This is going to reach easily from the rear bumper of your truck to the truck bed.
It is going to be custom fit for your vehicle. It's going to come with zip ties to secure any excess or slack in the wiring. It's going to come with the hardware that's necessary to get the 7-way connector installed in the truck bed. When it comes to the installation, you'll want to go off the detailed instructions. These are going to walk you through the installation process step-by- step. Basically, you're going to connect this area right here to your factory wiring harness.
Then you'll need to locate a suitable mounting point and route the harness to that location. According to the instructions you are going to need to use a whole saw to drill a 2 and one-eighth inch hole. That's going to be the mounting hole for the connector that's right here. These two pieces plug together. The other thing I like about it, it's got the 90 degree connection.
You can imagine that your truck bed is going to be sitting right behind this portion here. This will allow it to go down along the bed. It's going to be hidden because this is going to be between the outer wall of your vehicle and the bed of your truck. That's going to go down in that cavity and then you can secure the wiring with all the zip ties that are included with the kit. It does require a 2 and one-eighth inch hole to get this mounted. Once you get that in there, you can go ahead and secure the connector in place with the included hardware. It's got the spring-loaded lid on it. It's a nice design. Here on the inside it's going to have a gasket. That's going to create a nice tight seal, which is going to prevent moisture and dirt from getting to those connection points. That's going to do it for today's look at part number C56000. This is the CURT 5th wheel and gooseneck custom wiring harness.

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.

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 - 11/01/2017by: David12/16/2017
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

Wow! 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

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!

As described, priced good, what we wanted, chose fast shipping and paid for it and got it when we needed it. Thank you 557914

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.

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
by: Kevin L09/14/2016
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.

This 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 - 08/31/2017by: Tim S.07/23/2017
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

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

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
by: Donald R03/10/2018
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

Quick and simple installation!! 394759
by: Josh05/31/2017
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
by: ABM RANCH04/08/2017
Quality product. Connectors snapped right into place. Plenty of cable length. I tested with my trailer after installing and it worked perfectly. 364611
by: Chris03/12/2017
Paid someone to install it, worked great after install. Just don't forget to unplug before you unhitch like I did! 351880
by: Lee s03/05/2017
Fit the truck perfectly. The length was excessive. Would order the 7 foot for a 6.5 Foot bed. 348737
