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


Comments

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

by: diggerules02/24/2017


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

by: Nolan Anderson03/15/2017


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

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

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

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

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

by: Justin D.11/12/2016


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

by: Josh H07/12/2016


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

Ease of installation was like a hot knife through butter. Wouldn't have had to go with junction box but it prove to be a clean job opposed to what was there on a 20 year old trailer a 3 new owners. 420332

  • Recommended Complete Disc Brake Conversion System For 10,000 lb Dexter Axles
  • To replace your leaking seals, you will want the Unitized Oil Seal # 10-51. This is a confirmed fit for your hubs. I've attached a video of an oil seal installation on a similar hub to help. For your disc brake conversion, you will need to use the Dexter Trailer Hub Assembly - 9,000-10,000-lb Axles - 8 on 6-1/2 - Oil Bath # 8-288-3UC1 and then the Kodiak Disc Brake Kit - 11" Rotor - 8 on 6-1/2 - Raw Finish - Leaf Spring - 10,000-lb Dexter # K2R1058D11E compatible with these hub assemblies...

  • 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,...

  • Wiring For Trailer With Brakes For Compatibility With 7-Way Connector On 2016 Dodge 2500
  • Since your 2016 Dodge 2500 has a 7-way, I recommend just adding a 7-way trailer wire connector to your trailer like # H20046. This will give you a simple connection between your vehicle and trailer without converters. You can simply tape up the wires you aren't using at the trailer and leave them in your junction box. If you want a 7 way with junction box, you can use the Epicord 7-Way Molded Trailer Plug with Junction Box - 10' Long, # 277-000141. Adding this molded 7-way plug will...

  • Parts Needed to Install Trailer Brakes on a Load Rite Trailer Model UT6512
  • Looks like your Load Rite trailer UT6512 has a 3,500 lb axle. Most likely it's a standard 3,500 lb trailer axle but first you have to check to see if the axle has brake mounting flanges. If you can get back to me with whether or not you have brake flanges and the brand of your axle (most likely Lippert or Dexter) I can see which kit we have that may work. Check out the link I attached to see a guide to use for adding brakes to your trailer.

  • 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.

  • 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.

  • Complete Electric Brake Installation for 2,000 lb Trailer Axle
  • With the axle measurement and the bearing number, I can confirm that you have 2,000 lb capacity axles on your trailers. You will want to get the Brake Mounting Flange, # 4-34, to weld onto each side of each axle. 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....

  • Adding Trailer Brakes to a Timbren Axle-Less Trailer Suspension System
  • Yes, it is possible to add brakes Timren Axel-Less Trailer Suspension System. The Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/Flange - Off-Road Tires - 2.2K, # ASR1THDS03, that you were looking at has the brake flange mounted, so it is ready to add brake assembly and hubs to. I'd recommend getting the Electric Trailer Brake Kit - Self-Adjusting - 10" - Left and Right Hand Assemblies - 3,500 lbs # AKEBRK-35-SA . You would then pair these with the Trailer Hub...

  • 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 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...

  • Parts Needed to Add Electric Brakes to 6 x 14 Cargo Trailer with a 3,500 Pound Axle
  • The brakes I suggest for your 3,500 pound axle are the self-adjusting # AKEBRK-35-SA assemblies. Since they're self-adjusting you need to do an adjustment when you install them but that's it. The hub and drum assembly to match your bearings and bolt pattern is # AKHD-545-35-EZ-K. This includes new bearings, races, grease seal, grease cap, and lug nuts. For the 7-way trailer connector I like # 277-000141. It's attached to a junction box to make wiring everything easier. You'll also...

  • Wiring Diagram for Home Made Trailer
  • I've linked an article on trailer wiring that includes a diagram you might find helpful. One solution to help wire everything together is to use a junction box with your trailer's 7-way connector, like # 277-000141. This way you can run all of your trailer's wires to the box instead of to the back of the connector. To wire you brakes you'll want to use 10 gauge wiring # 10-1-1. For the lights you can use 16 gauge, # 16-1-1. Both are sold by the foot. When looking into the back...

  • Troubleshooting Electric Brake Controller Not Functioning with Electric Over Hydraulic Actuator
  • The Draw-Tite I-Command Trailer Brake Controller - 1 to 4 Axles - Proportional # 5535 could possibly be bad since you have a read out for normal braking, but no manual override or braking taking place. However, I don't believe this controller is compatible with EOH systems. You can test it and see if it is functioning correctly or if you may have a bad wire using # 3808 to test the brake output wire about 6 inches behind the controller. If you have power when you hit the brake pedal and...

  • Troubleshooting Pop-Up Camper Trailer with Non-Functioning Lights
  • Since you are now dealing with troubleshooting trailer wiring you are no longer a novice! The best way to go is to isolate the problem to either the vehicle or the trailer. If no lights at all work on the trailer then this makes me suspect the vehicle wiring is not activated. Some vehicles may need fuses or relays installed to activate factory or aftermarket wiring. Without knowing your vehicle details the best suggestion I can make is to get a circuit tester like # 3808 and apply it...

  • Parts Needed to Add Brakes to Single Axle Boat Trailer
  • You can increase the size of the wheels and tires on your boat trailer so long as you have enough room in the wheel/fender wells. Normal suspension travel usually dictates no less than 4-inches of clearance at the top of the tire. Provided you have enough room to prevent the larger tire from contacting any trailer surface you can go with ST205/75-15 rims/tires; the linked page displays all products that combine a 5-on-4-1/2 rim with a 205/75-15 trailer tire. For instance, part # A15R645SMD...

  • Wiring the Traditional Trailer 7-Way to 7-Way RV Standard
  • The Mighty Cord 7-Way RV-Style Trailer Connector, # A10-7W8, will have the same wiring configuration as the Hopkins 7-Way Molded Trailer Wire Connector, # H20046. I recommend the Epicord 7-Way Molded Trailer Plug with Junction Box , # 277-000141. The junction box will allow to easily connect your trailer wiring to the new 7-way cord. Using 7 of the Ring Terminal - 12-10 Gauge Wire, # 44-5310A, you can connect your trailer wiring to the junction box. The box can attach to the trailer...

  • Recommended Hubs And Electric Brake Assemblies For Tandem Axle Snow Bird Snowmobile Trailer
  • You can add electric brakes to both axles of your Snow Bird Snowmobile Trailer. To do so you will need new drums only on the axles that don't currently have brakes. You may be able to use your current surge brake hubs for your electric brake assemblies, but often electric hubs on this smaller size require a change due to thickness of the hub. For your hubs, I recommend the Trailer Hub & Drum Assembly - 2,200 lbs. Axles - 4 on 4 # 8-173-16UC3. For your electric brake assemblies, I...

  • 7-Way Box Bracket for Trailer Hitch Tube Attachment and Metal 7-Way Recommendation
  • We have plastic boxes for mounting a trailer connector like the part # 18156 but none that are made of metal. Plastic would actually be better though since it wouldn't corrode over time or potentially scrape the paint of the hitch off which would allow for additional corrosion. For a metal 7-way socket to fit this the part # PK12703 would be a great option as well. Then for a 7-way that you could install on your trailer that comes with a junction box you would want the part # 277-000141....

  • Wire Gauge Sizes in Epicord 7-Way Molded Trailer Plug with Junction Box
  • The wire gauges in the Epicord 7-Way Molded Trailer Plug with Junction Box # 277-000141 are as follows: White = 10 Black = 10 Yellow = 14 Green = 14 Red = 14 Brown = 14 Blue = 12 The wire gauge in the Epicord # 277-000141 changes with different functions of the wires. Signal wires, like yellow, green, red, and brown, draw less amperage so they use a lighter gauge wire. Heavier gauge wire is used for functions like the brake signal, ground, and 12V power because they carry...

  • Recommended 7000 lb Capacity Trailer System with 5 on 5 Inch Bolt Pattern
  • I am happy to take a look at your axle layout drawing. From what I'm gathering it seems like you have a desire to use an 89 inch 3500 lb axle with 5-on-5 inch bolt pattern. For your axle, you will want the Dexter Trailer Axle Beam with EZ-Lube Spindles - 89" Long - 3,500 lbs # T3584F-EZ-8974. For your hub/drums you will want the Dexter Trailer Hub and Drum Assembly - 3,500-lb Axles - 5 on 5 - E-Z Lube # 84556UC3-EZ or the idler hubs # 84550UC1-EZ. For brake assemblies you will...

  • Options for Mating 4-Pole Flat Vehicle Wiring to Jayco 6-Pole Square Trailer Wiring
  • The 4-pole to 6-Pole Jayco wiring adapter # 30104 supports only the 3 circuits on the 4-pole but converts them to the connector format used on older Jayco trailers. A 4-pole wiring setup has a ground and three circuits; right stop/turn, left stop/turn and tail lights. The Jayco connector has a ground and 5 circuits so using this adapter would let the basic lighting signals from the Explorer's 4-pole reach the trailer but the other functions supported by the Jayco plug would NOT have any...

  • Recommended Actuator and Wiring for Boat Trailer Upgrade From Surge Brakes
  • To add EOH to a surge brake trailer, you will need to add the electric components to make the actuator function. You can get the Epicord 7-Way Molded Trailer Plug with Junction Box - 10' Long # 277-000141 and then wire your actuator into that junction box. You will be able to simply connect to your current hydraulic brake lines. For your actuator, I recommend the HydraStar Vented Marine Electric Over Hydraulic Actuator for Disc Brakes - 1,600 psi # HS381-8067 or the HydraStar Vented...

  • Wiring Needed to Rewire a Trailer for Lights and Electric Brakes
  • Both the # A40W5B and # W002290 have a blue wire that is only 5 feet long. Plus, the blue wire is only 18 gauge and 20 gauge, respectively. So these are not going to work for your application. What you're going to want to use is Bonded 4 Wire # 16-4B-1 which is sold by the foot. This will provide the four 16 gauge wires to run from the junction box, part # 277-000141, to your trailer's lights. Then for the brakes you will want a 10 gauge wire, # 10-1-1, which is also sold by the...

  • Parts Needed to Operate Electric Brakes on Roadmaster Tow Dolly to Tow a 2014 Fiat 500L
  • It sounds like you're trying to power the lights and brakes on the Roadmaster RM3477 tow dolly. To do this you will not want to connect the dolly to the Fiat that's being towed but rather to the RV that's towing it. I assume the RM3477 has a 4-way connector on it because Roadmaster dollies often do. Even though they need a 7-way to power the brakes. What you'll need is a 7-way trailer connector like # 277-000141. This has a junction box attached to it which will make it easier to...

These assemblies need adjustment only at install and then will self-adjust as needed.
