Video Transcript for Epicord Wiring 277-000141 Review

Today we're going to be taking a look at the Epicord 7-Way Molded Trailer Plug with the included junction box. This is going to provide an easier way to get your trailer wired. It provides a 7-way connector for your trailer, that way you can easily get everything connected to the 7-way port on your tow vehicle. The 7-way trailer end connector is already connected to the correct locations within the box. All you have to do is run your trailer wiring inside the junction box, match it up with the correct functions and you're going to be ready to go. This is going to measure 10 feet long. It's a heavy duty cord so it's going to give you the length that you need and it's going to provide the protection to the wires that we're looking for.

It's going to feature a weatherproof and corrosion resistant design, which is going to help insure that this plug is going to last for years. Taking a look at the trailer end plug right here, that's going to connect to the tow vehicle. It's got the finger tabs, which allows for easy connecting and disconnecting, and it's got the tab here on top, we call that an alignment tab and that's going to align in the groove in the socket that would be on the 7-way connector on the vehicle. We're going to take a look inside the junction box real quick. It's got 2 screws here on top that holds the lid on to the bottom portion of the box. They'll be Phillips head screws, we can easily remove those. Then we'll point out some features about the box.

The lid easily comes off. Inside here, you can see that it's going to have the posts. I do want to mention that these posts are going to be color coded, they've got the tips colored. It's going to say the color coding on this side of the posts and on the bottom side it's actually going to label the functions. So right here, it's white, it says white on this side and on the underside it says ground.

So we know that the white wire connects to the white post and that's going to be the ground function. That's going to be our ground wire. Also, I want to point out that on the 2 ports right here to run wires through, we'll see that they've got the rubber plugs. I'll just go ahead and remove all of those so we can get a better look at it. It's going to have set screws located in here so that way, when you run the wiring through, you can tighten down those set screws and it's going to bring a clamp down over the wires which is going to help keep dirt and moisture and any other elements out of the box. It's going to come with solid plugs, that way whatever holes you're not using .. You've got 2 on this side and then 1 on each side of the box.

Whatever holes you aren't using, you can use those solid plugs to cover up. It's going to come with 4 plugs that have pre-cut holes in them already. That way you can run your wires through. That acts as a grommet so it still allows you to run the wires through, but it's going to keep out anything that could pass by the wires. Both of those are included, 4 of each. 4 solids, 4 with pre-cut holes. It seems like a really nice design. Again, weatherproof and corrosion resistant design. Hardware is included for each connection port inside the junction box. Your mounting hardware is sold separately. You can see here on the bottom of the box, we're going to have 2 mount hole locations, 1 on each side. If we take a measurement, the distance between those mount holes, that's going to give us a measurement of 7 and 3/8ths of an inch. The overall length from edge to edge, those mounting tabs, that looks to measure about 8 and 1/8th inches long. The width of the box, that's going to measure about 3 and 1/4 inches. Let's go ahead and put that lid back on and then we can go ahead and give you a measurement of the overall height as well. The diameter of those mount holes is going to measure 5/16ths of an inch. Again, mounting hardware is not included so that will need to be provided separately. We'll take a look at the overall height of the box, we can see that that's going to give us a measurement of about 2 and 1/4 inches. This is CETL and ETL US listed, which means that this product has been tested and meets the safety standards for use in Canada and for use in the United States. That's going to do it for today's look at the Epicord 7-Way Molded Trailer Plug with the included junction box.

Epicord 7-Way Molded Trailer Plug with Junction Box - 10' Long - 277-000141

I installed this product yesterday and it is a really nice product. It would be a great product if the darn wire colors from the plug were the same as the industry standard. But if you go by what is on the small mount that the wires screwed to it is accurate. I got the longer 10' cable as I wanted to mount it further back than the stock metal electrical box that they mount all the stuff in from the factory. I ended up mounting it on the bottom side of the cross braces on the bottom side of the trailer. I also installed a seperate fuse box to individually fuse all the circuits so that if anything on the trailer shorted out it wouldn't blow the fuses in the truck. 318401

I loved that I got the longer replacement so I was able to move it to a more easier place to access.

Anthony was very helpful,I needed a trailer pig tail and junction box 7 pole. Was going to order two items.Anthony pointed out that a combo kit was avialable for a substantial savings. Anthony notified me product was not avialable but kept update when it was. He also notified me when it was going to be shipped and it arrivied on time in the best possible condition. I have done business with E-Trailer before by this experience was far beyond just a business tranaction with a customer.Hope all tranactions will be as pain free as this one was.All wire from trailer frame was remove before restoration,new box made rewire easier and neat. The only issue i have is that a wire schematic was not included with the harness and box . Would have made it easier to install for those who don't know the wire paths. Thanks Steve Koza. 325076

Used this to convert a trailer from 4 pin to 7 blade connector so that I could add brakes. Gives a nice place to terminate your wires. The wire color guide on the product page was very helpful when it came to wiring up the trailer. Plan on putting some type of sealant around the wires because unless you use a large 7 conductor wire there will be a gap where water could get in. 423934

Ordered this to replace the very poor factory wiring on my 18 foot car trailer. Very impressed with quality and with quick delivery of product. I would recommend measuring your trailer to make sure the 10 foot cord is not too long. I didn't measure first but I was lucky and was able to make it work. Only complaint is what many others have said about the wire color. I know wire color may vary based on manufacturer, but the standard wire color chart on this very website is different from the colors in this plug. It is not hard to figure out, mostly just annoying having to use a circuit tester to verify the wires or having the color chart pulled up. Overall great product, Just annoying about the wire color. 396368

I ordered these items for my DIY project, turning my bumper pull trailer into a goosenech trailer. The parts are of good quality and the delivery was quick. I would highly recommend for anyone who needs something for a DIY project to order from ETRAILER.COM I went from that to this. 339045

Last project built. Used etrailer for almost all parts, 7 pin wiring harness, junction box, tail lights, jacks vent cover and so. Love the leveling jacks. Friend wants one now so started another one. I will be getting all the parts from etrailer... 486389

This product is great!! It is probably overkill for my little utility trailer but I was tired of re-wiring it for shorts in the crappy standard wire that came with the light sets. This junction box feels very sturdy and has the cable/plug is very hefty as well. Easy to setup. The colors didn't match what my car was but it is very simple to swap the terminals to what you need. I forgot to take more pictures through out my install. 345179

This trailer plug has been a great addition to my boat trailer. It gave me the extra length of cord needed to remove tension from the connection / plug and cord that I had with my old cord and allowed me to eliminate the adapter I was using to connect the trailer to my truck. It was very easy to install, great quality construction, and has held up very well during normal use in and around the lake. etrailer staff was a huge help in helping determine if this was the best product they offered for my application, which helped me make this purchase decision. I highly recommend etrailer.com and this product. 506141

This is a great part It made wiring in the trailer very easy. It fit underneath the gooseneck and mounted up real nice. I recommend it to anyone that needs to rewire their trailer. 353210

by:


Cord was excellent. I was concerned about the wiring of the plug, but the wiring was completely compatible with my 2015 Ford Expedition and Airstream Trailer. (Yellow auxiliary center wire) No changing around of colors on the wire ends. Great!! It would be nice if Etrailer also sold this cord without the box, as I have a great box inside the Airstream for wiring, and had to remove the box to run the cord through the frame tube. But, for the price of the entire product, the box was really a nice "gift" for those who need it. Thanks, Etrailer. 377375

It was very well made and we have had NO problems with it. Thanks.

I bought this to replace the cord on my 5th wheel. The original one is OK, but the plug doesn't lock into the new receptacle I installed in the truck bed. This new plug is molded to the cord, and has dual contacts (better electrical connection) and the lug is of the proper dimension to hold it securely in the receptacle. The construction of the terminal box is satisfactory, the wire sizes are adequate, and the cord jacket appears to be thicker than most. The cord is flexible. 412723

I have had this for a year now on my gooseneck flatbed trailer and have had zero issues. I plan to buy this for my horse trailer as well. The box stays sealed and it is supper easy to add connections to or check wiring with a multi-meter when a light quits working. The end is holding up well and I have no connectivity issues. The cord is long enough for 90 degree turns with plenty of slack (plug is in bed). I definitely recommend this product. 497347

This is worth every penny as far as im concerned. Makes wiring up everything on trailer from plug to tail light so much easier. The junxtion box also makes finding shorts easier since it is the hub for all accessories. 474225

My daughter bought a used trailer for her horse. The wiring plug wasn't in great shape & there was no junction box, the cable was only connected to the trailer wiring with wire nuts. I bought the Epicord 7-Way Molded Trailer Plug with Junction Box & installed it. It's working great. Also, if there are any electrical issues down the road, I now have a break out box to check voltages, shorts, etc. 425171



- 277-000141

by:


This is a nice setup, however the hardware in it should be made out of stainless or something more weather resistant. Also as for me knowing the color of wires and to where the colors are supposed to go and what they are for - THATS not the case here. None of the color wires in this are actually what they are for except for the black 12+ wire and the white ground wire. It will work for now though! 520348


Comments

Because theres more than one accepted wire color code for trailer wiring, Its recommended to wire by function, not color. You can use a circuit tester like # 40376
Circuit Tester Kit
$66.21
to test each function in the junction box while the harness is plugged into the tow vehicle and each function is activated, then wired accordingly.

Epicord 7 pin appears good level product. However installation is not strictly color to color. Keep in mind that black hot wire from trailer goes to black 7 pin black terminal, which is fed by commonly red wire from battery positive side. Therefore, red positive from battery does not go to red terminal on epicord box. That terminal is for one of your left or right turn signal/brake lights. 423169

The junction box and cable are of durable materials, with plenty of cable. With all the wiring I'm bringing together I was trying to avoid a huge splice ball which looks mediocre. But now I can land all my wiring neatly and professionally. And the beauty is I can add wiring or work on existing without having to undo a big knot. 498941

I ordered all the equipment to help my son rewire his enclosed trailer. We got everything as ordered and it all worked out great. I had emailed etrailer multiple times to discuss what exactly I needed. They were great and their help was above and beyond. Any trailer parts, wiring, etc., you need, this is the place to get it! 483866

This is a premium product and I was completely satisfied with quality, fit and construction. I really like that the plug is molded and offers limited opportunity for water ingress. Box is heavy duty, and well marked. This will save a lot of time over hand fabricating a cable assembly and should provide years of service. 423511



- 277-000141

by:


The cable was needed because I allowed mine to drag on the ground and no longer was usable . The box come off to run cable through frame and was easy to install. The trailer wiring was only installed with wire nuts an now upgraded to ring lugs. Your trailer my have different wire size so 10,12 and 14 gauge 484227

by:


I am a Union Electrician, so a clean installation is important to me. This product allowed me to wire up the custom trailer I built neat and clean. The terminal lugs are of good quality and the cable bushings (rubber grommets) offered flexibility for various cable and wire sizes. Overall a well built unit. 521428



- 277-000141

by:


This was very easy to install and of high quality. Having all the pegs color coded and labeled saved a lot of time. The color coding was typical of a travel trailer or 5th wheel scheme. I mounted it with 1 1/4 in self tapping stainless screws from any hardware store. 316130

Order was complete and delivered in a timely manner. Only problem (minor) was the 7way pigtail was not wired to color code. Had to use test light to get 3 of the wires in correct location. Could be a problem if someone wasn't comfortable with ringing out wires. 375359



- 277-000141

by:


Seems to be high quality, and sealed Just wish it had a diagram of what color, is what position on the plug. Its not a big deal most likely follows standard color code I'll just verify before I wire it up. Overall very happy with purchase 271011

With that flange in place, you will want to mount the 7 inch Electric Trailer Brake Assembly # AKEBRK-2L on the left side of the axle and the # AKEBRK-2R on the right side of the axle. These are nearly identical parts, but installing on the correct side is very important....

  • Can 7-Way Junction Box 277-000141 Be Used to Charge Trailer Battery
  • If there happened to be a 12 volt keyed power source in the circuits of the # 277-000141 you could use it for the isolation solenoid # TR118665. Essentially you would need to have the 12 volt circuit of the vehicle already be only active when the key is on. Which if that were the case you wouldn't need the solenoid realistically. If the 12 volt circuit of your truck's 7-way is active all the time you would need to install the solenoid on that circuit and that would get the circuit active...

  • Recommended Trailer Wiring For 2017 Toyota Land Cruiser
  • For your 2017 Toyota Land Cruiser Diesel, none of our companies have a confirmed fit customized wiring kit for your vehicle. Because of this, I recommend you go with the Tekonsha ZCI Circuit Protected Vehicle Wiring Harness # 119250KIT. This will allow you to install a 4 way flat connector on your vehicle using a zero-contact interface sensor system that does not require splicing or cutting wires. This will be compatible with your factory wiring getting signal without piercing the insulation...

  • Recommended Wiring For A 1998 Chevy C/K Series Truck
  • For your 1998 Chevrolet C/K-Series 1500, I recommend the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, # 118315. This harness plugs directly into existing wiring with no splicing to cutting required. This will give you a 4-way connector. If you want to add a 7 way trailer connection, then I recommend the Universal Installation Kit for Trailer Brake Controller - 7-Way RV and 4-Way Flat - 10 Gauge Wires, # ETBC7. This will give you all the connectors, circuit breakers,...

  • Recommended Disc Brake Conversion on 10,000 lb AL-KO Axle
  • I reached out to Dexter Axle and spoke directly with their AL-KO/Hayes specialist. They said that there is not a conversion to disk brakes for their axle based on the axle itself. The issue is with the mount for the brake calipers. If you can fabricate mounts, I can give you everything else that will make your trailer compatible. I recommend the Redline Trailer Hub Assembly - 10,000 lbs Axles - 8 on 6-1/2, # 090814. These are compatible with your axle. This hub includes the races,...

  • Electric Trailer Brakes Won't Release After I Hit Brakes
  • On a 5-way connection, the blue wire is normally for the brake controller as you stated. However the color of the wire in this case probably won't help us as it is evident this connection has already been tampered with. I have attached a trailer wiring diagram for you. The focus should be on the function of the wire and not on the color of the wire, so we can pair the correct functions at the trailer and vehicle connection points. To test the trailer wires, you can get a 12 volt batter...

  • 7-Way Wiring Harness for 16-Foot Trailer
  • We can help you with a replacement 7-way trailer harness for your 16-foot trailer. All such items are shown on the linked page. These include plugs-only, such as # PK12706, which uses your trailer's existing wiring; pigtail plugs like # 50-67-005 that are available in many lengths; and also complete units like # 277-000141 which is a 7-way plug with cable and wiring junction box. If you are referring to a replacement 7-way socket for your 2006 Nissan Titan then you can use # C55774...

  • Troubleshooting Trailer Wiring on 2014 Dodge Ram 1500
  • It would be unusual for all three relays in your 2014 Dodge Ram 1500 (or any other vehicle) to all go bad at once. If this did happen I would suspect the vehicle or trailer wiring/connectors. It is possible for internal corrosion to build up that could cause a short-circuit. This can occur on the visible parts of the sockets or plugs but it can also develop on the inside of these connectors, where it is very hard to spot. With enough exposure to the elements the trailer socket or plug could...

  • Wire Gauge to Use With Epicord 7-Way Molded Trailer Plug
  • The Epicord 7-Way Molded Trailer Plug with Junction Box # 277-000141 does have 12 gauge wire, which is appropriate. It can also be 10 gauge, however; either would be fine. I've added a pair of links to video reviews of this product for you to take a look at.

  • What is Needed to Tow a M105A2 Military Trailer with a 2013 Dodge Durango?
  • To convert your M105A2 military trailer to a 7-blade, I would recommend using the Epicord 7-Way with Junction Box # 277-000141. This makes the conversion simple and you don't have to worry about wiring the connector itself. You'll also need some ring terminals like # 44-5310A and some loom clamps like # A0500. The wires in the junction box are color coded as indicated below. Military wiring is typically not color-coded, so you may need to use a circuit tester like # ALL640595 and a 12V...

  • Recommended 7-Way Wiring Harness For 2000 Sundowner Horse Trailer And 2013 GMC Sierra 3500 Dually
  • For your application, I can absolutely give you the wiring function locations. I've attached a picture to assist. Based on what you mentioned, I think I have a better option for you. I recommend the Epicord 7-Way Molded Trailer Plug with Junction Box - 10' Long # 277-000141. This will allow you to connect your wiring at a junction box using the ring terminals like # 44-5310A, and then uses a molded plug so you won't have the disconnection issues as you plug and unplug your 2000 Sundowner...

  • Recommended Brake Assemblies for 1995 Coleman Fleetwood Utah Pop-up Camper
  • If your drums are 7 inches, then you will want the Electric Trailer Brake Kit - 7" - Left and Right Hand Assemblies - 2,000 lbs # AKEBRK-2. Many people upgraded those trailers and added a 3500 lb axle, so if you have 10 inch hubs, you will want # AKEBRK-35-SA instead. If you need wiring, I recommend # 10-2-1 for your brake wiring and then the Epicord 7-Way Molded Trailer Plug with Junction Box - 10' Long # 277-000141 for easy and clean connections. The ring terminals # 44-5310A make...

  • Recommended Electric Trailer Jack And Wiring To 7-Way 12V Connection
  • For a 3500 lb Electric Jack, I recommend the Bulldog Powered-Drive Trailer Jack - Drop Leg - A-Frame - 14" Lift - 3,500 lbs - Black # BD500187. This jack uses a 12 volt system, so it is compatible with your 7-way although a battery is always a better option like # 20099. To use the 7-way, this can be done by splicing into the trailer harness wiring or using a junction box like # 38656. If you want the juction box and 7 way you can use # 277-000141. Whether you choose to splice into...

  • Replacement Parts for 1970s Camper Frame with Dayton Fayette Axles
  • The Lippert Components Heavy-Duty Replacement Shock - Yellow # LC283280 is 8.625 inches compressed and 13.5 inches fully extended. Your current suspension may extend and retract slightly further but the shocks will be a good replacement based on the actual shock absorbing as long as they will fit your brackets. Unfortunately we don't have any info on your axle or hubs, so to help, I will need to get the bearing numbers printed on the face of your inner and outer bearing of one hub....
