Video Transcript for Bargman Custom Fit Vehicle Wiring Harness Installation - 2011 Ram 3500

Today, in our 2011 Ram 3500, we're gonna be installing Bargman's fifth wheel/gooseneck 90-degree wiring harness with seven-pole trailer connector.This 90-degree harness is gonna give you a seven-pole connector inside your truck bed for hassle-free hookup of your fifth wheel or gooseneck trailers. What's great about this harness is that there's no cutting or splicing required. It simply plugs in line with your existing seven-pole connectors.What that means is that you'll also be able to use your current seven-pole that's at the back of your vehicle in addition to this one. You don't lose any of your flexibility that your truck had before. You just gain more flexibility. Most of our customers use this with gooseneck and fifth wheel trailers.

It's an easy, hassle-free way to make a connection without having to drape it over the back of your vehicle.You can keep all of your wiring contained inside the bed of your truck. Additionally, it's gonna be closer to your fifth wheel and gooseneck wiring. If you had an issue where your wiring wasn't long enough before, with the ability to mount this however you'd like in your truck bed, you can be sure that it's gonna reach now. The connector itself has a spring-loaded cover with a gasket seal on the inside to keep out any dirt, debris, and moisture, ensuring a long-lasting connection. Now, when you're not using it, it just snaps right back shut.

It comes with all the necessary hardware you need to get it installed, which includes the self-tapping screws and a spacer block in case you need to push it some to fit in some of those tighter areas.This is what your trailer harness is gonna look like when you get it. This is the nine-foot version with the standard seven-pole connectors. As you can see here, we've got a female and a male end, so it plugs simply in line with your existing seven-pole connection allowing you to route the 90-degree end somewhere in your truck bed, wherever it works best for you. The entire harness is gonna be insulated from end to end, so you're gonna have a nice, thick coating on the outside to protect it from any road debris that may fly up at it and any sharp edges that you may come in contact when routing your wiring.We've got the nine-foot long version of the harness right here and we've got a long bed truck behind us.You could see, as we stretch it out, it's plenty long to go from front to back on your long bed truck. You'll begin your installation by cutting out a two-inch hole in order to fit your wiring through.

What I used here was the spacer block that comes with it and this allows you to space it out a little bit in case you don't have enough clearance between the wall here and the outer quarter panel behind it. For it to fit, you can pull it out some to get that clearance, but it also makes a great little template for you to mark out where you wanna place it. I've already gone ahead and marked that.We'll now use a quarter-inch drill bit to make a pilot hole in the center of where we marked.Once you make your pilot hole, we'll step it up to that two-inch with our hole saw here. If you've got any kind of spray-in liner or anything like that, I like to actually start in reverse just to get through that paint liner and then, switch it back over to the correct direction to cut through the metal. We can just push that in.

It'll fall to the ground. Well, now, we'll clean up our metal shavings here and we'll use some clear coat to seal up the exposed metal there, to help prevent against rust and corrosion. We can now feed our harness in through the hole and down towards the bottom.I like to go in with the shorter one first because it's a little bit larger, as in wider, than our longer one here. Feed those in and then, feed them down. As you see here, our seven-pole connector goes flush up against our truck bed, which means we don't need to use our spacer. Sometimes, when you put this in, depending on the location you chose, you'll go to push it in, it won't be able to go flush, there'll be a little gap. This'll take up that gap for you, so we'll now hold our connector level. We're gonna use the self-tapping screws that come with the kit and an eight-millimeter socket to run those in.We can now go below and make our connection, we'll now take our wiring. We're gonna route it over to our existing seven-pole connector. We're gonna take it up above the frame here, pull all that slack over. Now, we can disconnect our factory seven-pole connector. There's a release tab located here. You'll just push that in and pull the connector off. We're gonna apply that to both of these ends here. If you need some dialature grease, you can fix them up here at eTrailer.com. The connector we disconnected, we're gonna plug into our new harness here. The other end of our harness is gonna plug right back into the factory seven-pole.Now, all that's left is to take our wiring here and tidy it up, so we're just gonna roll it up and secure it to the factory wiring here with some zip ties. Now, zip ties don't come included with your harness, but you can fix some up here at eTrailer.com. Now, just snip off the end of our zip ties here and the installation is complete. Ready to hook up your trailer and make sure all your light's working properly. We're gonna plug in our tester and verify that all of our lights are working properly. You'll wanna make sure that you have your left turn signal, right turn signal, tail lamps, and brake lamps.Additionally, if you've got a brake controller installed, you wanna make sure you have your brake controller output. With everything working properly, we're ready to hit the road. That completes our installation of Bargman's fifth wheel/gooseneck 90-degree trailer wiring harness with seven-pole trailer connector on our 2011 Ram 3500.

This wiring harness was very easy to install and pluged into the existing factory harness. The "how to" videos were very helpful also. The outlet in the box is nice because the cord does't have to go over the tailgate and may not reach the outlet on the bumper. The web site was easy to use. Shipping was fast and on time. Don't change anything! 171466

Shocked, Surprised, and Amazed are a few words I would describe the ease of installation for this harness. Literally less than 20 minutes and I am NOT a mechanic...worked great and I would recommend to anyone. Great product! 138337

2014 Chevy 3500HD

Installed on a 2014 Chevy 3500HD crew cab, long bed, dually with trailer towing package but without camper wiring option. Installation was easy, aside from the thought of drilling a hole in my new truck bed. I was doubtful of the 2" hole where most others specify 2 1/8, but the connections squeaked through the 2". I located the new plug toward the tailgate, above one of the tie-down hooks so it's easy to reach from the rear of the truck, but still out of harm's way. My old truck had it in front of the wheel well and a short person had to climb on the tire to reach it. My 5-er's wire harness comes out of the back of the hitch assembly anyway. There was plenty of clearance for the plug and wire inside the bed walls. Once I snaked it along the frame, it was plug and play with the receiver hitch wiring harness. I put some dielectric grease on the contacts to prevent corrosion. A few cable ties and I was done. The only negative: due to the locating it toward the rear of the truck bed, I wish they offered a shorter harness. 150298

The only issue Ive had with the wiring is that the plug from the 5th wheel would occasionally come loose and Id lose a couple of the connections. I now put a velcro strap around the cap

Will try to keep this as real as it gets out there. 2015 F250 XLT Crew Cab 8' Bed Ordered the Reese Elite Gooseneck and Barger 90 degree wiring harness. Received the gooseneck hitch and harness quickly. Free shipping got here in two days. Item came in two boxes. The rails were poorly packaged. Box was basically open and beat to hell, leaving markings on the rails' paint. Didn't bother me, but might others. The pucks were loose in the box and were lucky they did not fall out. The second box with the ball, ball mount, harness and misc. hardware was packed so well it took about 5 minutes to take off all the staples and then each product was individually boxed inside. Wish they would treat the rail box with the same care. Instructions are ok. Used the online install video instead. The video is slightly simplified as getting the nuts on the bolts is a slight challenge for a one man install. I was able to do the entire installation by myself with the exception of the four rail-to-frame bolts. Getting these snugged up to the point of being able to torque took two people simply because the nuts are hidden on the backside of the rail...particularly the driver-side front...which is slightly behind the gas tank, but still accessible. My F250 is factory lifted 4-5" so I did not have to remove the rear wheels, nor did I have to remove the spare tire or heat shield. Lower trucks will need the rear wheels pulled. Installing the ball mounting plate took some doing. Got one bolt on then decided to actually install the ball into the plate from above pulling the plate tight below. I used vice grips to basically keep the plate mounted tight rather than trying to lift it from underneath with one had and bolt it with the other. For me the most time consuming part of the project was getting the darned bed bolts off to lift the right side. Broke the T50 bit they supplied and then two others. Finally gave up and ground off two of the remaining bolts...and ordered replacements. Tip for those doing this on their own, you may want to spray the bolts from under with PB Blaster the day before you intend to install. I forgot and the issue was likely that the bolts were rusted. The wiring harness was a breeze, although I wish a shorter version was available. (Perhaps I missed it). Had to loop/zip tie about 2-3' under the bed. Connecting between the factory connectors did require me to pull the mounting plate. Was a bit tight to just slip the new connector in. Also, working the harness thru the hole in the bed side was a bit tight. Install probably took 10 minutes after getting the holes drilled. Total install time for this slightly skilled guy was about 3-1/2 hours...after the bed bolts fiasco. Oh...and did it all with a cast on the left arm. Ha! Now to see how she tows! 431267

This is probably the easiest install you can do. The only thing to watch is the 2 inch hole is tight to get the two plugs and wire thru, just take your time and it will go. 703935

Bought this 7 foot harness to go in to my new 2012 chevy silverado. Wasn't sure where I wanted to put the plug receptacle in the bed. Watch the video and it show the installer putting the plug end down low in the lower left corner. If you haul dirt , mulch or gravel I felt this was a bad spot so I found another. Chevy has 3 plastic plug covers in both sides of the bed for a ladder rack/tool holder attachment accessory they sell. I pulled the middle plug cover out which is oval and with my dremel tool I made the hole round to the proper size and fed the wire down the hole and over the wheel well down to the back bumper where just like the video it shows how to make the connection. Mounted in the bed in this location the 7 foot plug lead gives you plenty of room to route and secure the wires out of the way. If you crank down the spare tire its easier to run the wire and secure the wire to different points. My bed has no new holes in it. The plug is up high out of the way which works for my fifth wheel and the plug was wired correctly so all the lights/brakes work like they should. Good deal 51693

It has been about a year since I installed the harness in my truck. Working great. Easy to install. Sure is nice to have the plug inside the truck bed then have the electric cord hanging over the tail gate to plugged it in. 758760

Worked great & customer service is above & beyond as usual- Had a question about the stock wiring connector while installing this, called etrailer & they got the answer right away for me. They are an awesome company to deal with. 751577

by:

I'm very happy with this kit. It was very easy to install, fit perfectly and works great. It is such an improvement, allowing me to plug in my fifth wheel and goose neck trailers in the bed rather than draping the cord over the tail gate. I highly recommend this kit. 747466

Nice heavy sheathing on the harness. Installation went without a hitch. It took me longer to decide exactly where to locate the plug in the body of the truck than to actually install. 737755



- 54701-003

Perfect fit. Old cable had flimsy wire protection. This product had very good sheathing for all the wires and should last a long time. 737476

Very well made, plugs right in between the factory harness. Maybe a foot too long (I ran it from the passenger side of the bed) but it’s not hard to zip-tie it up to where it’s not hanging down. 736212
