The trailer plug/junction boxes worked out very well! Using them made it a lot easier to rewire the trailer.
by: Blais Racing11/20/2016
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.

Very disappointed that the plug molding is too long for my truck's factory plug outlet. Look at it wrong and it'll fall out of the outlet. I tried trimming it down so the door would hold the cable catch, but the rubber is too soft.

The product is very nice real heavy duty but I must of wired it wrong because the brakes were on all the time as I was driving down the highway and cooked all 4 bearings and destroyed all 4 brake pads
by: Matthew 06/15/2019
Little over a year since install and no problem thus far with this product. The rubber grommets supplied with it keeps everything water tight. Wires are not colored coordinated! I overlooked that detail in product description and had to rewire everything, lol.

Actually, theres more than one accepted wire color convention when it comes to trailer wiring color codes which is why we list the function for each terminal/wire color in the product description.
by: Chase05/03/2019
It was just as expected. Good quality and no hidden issues.
For everyone else’s essay, the studs are 5mm. So, for the best fit grab you some 5mm heat shrink ring terminals. 1/4in for the mounting hardware. This went on my boat trailer, so I grabbed some stainless steel 1/4in hardware and used nylon lock nuts. I used extension cord for my wire runs. A grounded extension cord will give you your 3 wire runs for the tail lights, a standard 2 blade extension cord for any marker/running lights. Heatshrink adhesive butt connectors on all connections. The wiring info that ETrailer provides was correct for my 2019 F150.
Overall makes for a solid trailer light setup. Highly recommend this junction box.
by: Chris F. 08/22/2017
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.
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.
by: Allen02/09/2018
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.

I do business with many prevailers but I have yet to find one equal to E trailer. They are fantastic people to do business with and quality parts. Thanks for being in there.

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...
by: John05/01/2020
I needed to completely rewire my landscape trailer because of the poor quality of the original components. This is quality hardware. The only issue I had was the color/functions of the new component did not exactly match with the color/functions on my trailer. It was not a difficult issue to overcome.
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.

Great all in one unit
by: Ronald04/24/2018
I just finished mounting this to my trailer frame and it really seems to be a top notch product. It's so much cleaner looking and sealed connections.
by: Randy02/18/2019
I took delivery today and installed it onto the body of my slide in camper immediately. Installation was simple and effective. There's multiple slots for every applications. Everything works great.
by: Philip V06/02/2023
Absolute Garbage!!! Why would they not follow the 7 pin color code?? Red is reverse, green is running, brown is left blinker, yellow is right blinker??? Why would etrailer sell this garbage?
by: Mark11/05/2022
STOP!!! Wiring colors are non-standard.
The wiring colors do not match the standard. All of the colors are there, they are just rearranged. I hooked it up thinking that it was a color to color matchup like EVERY other product for 7-pin connectors and now I have to replace a special $xx fuse in my truck that I cannot get for 2 days. Not to mention the troubleshooting time.
There are standards for a reason, the products that you sell should adhere to them, or be clearly marked that they DO NOT. Simply listing the colors and hoping that someone notices they're wrong when they're ordering is insufficient.
I have 7 trailers and all of them follow the standard, except this one now.

Excellent product one more step to simplify our trailer building process
by: Dale S05/07/2017
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.

Can you provide a pin out / wire color vs location on the 7 way plug Epicord 7-Way Molded Trailer Plug with Junction Box - 10' Long - 277-000141 I ordered. I'm seeing several installs where the wire color on this plug dose NOT match standard trailer wire color. Also it did not come with any paper work or instructions stating this. Example yellow is standard trailer for left turn. This 7 way plug looks to maybe use yellow for aux power going by other install photos and research.
This will be a major set back as my trailer has already been compleated and went by standard trailer wire color. ?????

There is more than one accepted color code/wiring convention for a 7-way trailer connector. The color code for the Epicord 7-way plug/junction box is as follows: °White ground: 10 gauge °Black 12V power: 10 gauge °Yellow reverseauxiliary: 14 gauge °Red left turn and stop: 14 gauge °Green tail and running lights: 14 gauge °Brown right turn and stop: 14 gauge °Blue brake: 12 gauge. This is shown on the product description page on our website.
by: Tyrone 06/20/2023
Very happy with this product. I'm looking forward to installing it on my trailer. Very solid and well made.
by: Kenneth01/31/2019
This new cable and distribution box will make the wiring job quick and easy. Trailer previously had a 4-wire system (no brakes) and was not up to current standards for lighting, so I'm replacing everything electrical and adding the brakes. This will help immensely.

This project turned out great! I really like buying from etrailer. They always have what I need, along with great customer service and fast shipping.
by: Will M.05/23/2019
Love the 7 way barrel plug! Was easy to mount the junction box and connect the correct wires to the terminals once ring lugs were attached to the wires. Great light/brake trailer system cable and box!!!
Love etrailer.com!!!

Installed the Hopkins muti-tow 7, 5, and 4 way flat connector this morning. I ripped the original connector that was attached to the bottom of the hitch receiver off when I was 4-wheeling into the Doll House campgrounds in the Maze District of Canyonlands a month ago. So, I cut a hole in the bumper and mounted the new Hopkins connector, cut off the old broken connector mounting bracket, and connected the factory wiring to the new Hopkins device. Hopkins product installed easily, looks great, is now out of the way, and has the flexibility of multiple trailer connectors when required.
I am pleased with the product. Attached is a photo.
by: Mark W10/27/2017
Exactly what we had been looking for. Now I can hook up multiple trailers with different connectors and all the electrics on each trailer works. I mounted mine directly to the receiver hitch frame. The biggest challenge for us was routing the backup wire from the taillight housing, through the body of the truck to the connector. the rest went together fairly easily. Seems to be pretty solid and looks much better than the loose pigtail connector it replaced.
by: John05/21/2022
This is a Great product ! I built a trailer tester which is self powered and pretty much self explanatory on the way it operates. Using this connector gives the flexibility or connecting to a 4,5 or 7 way plug !
by: John L05/19/2011
I received the product quickly and in perfect condition the packing was excellant. I installed the connector easily and quickly. I consulted the Gm wiring diagram and als found the wires for all the 7 connections. I had a tight spot within the bumper edge, but managed to find short bolts to attach the bracket in old exsisting holes. The rest was easy attaching the connectors and making sure all wires were through the rear enclosure and tightening them down. I tested the 4 wire connector with my boat trailer lights and it worked like it was designed to do. I LOVE the versatility of this connector. Thanks etrailer.com!! Great product at a great price.

Installation of the plug was a quick and easy. The existing Warrior hitch has a tab on the side for a trailer wiring socket. Drill a new hole on the installation bracket (comes with the trailer connector) so the bracket on the hitch matches bracket on the trailer connector. Done deal. This is the only trailer connector I found which has the 7, 5 and 4 connector options. Flexibility is always a good idea when you are borrowing someone else trailer or renting.

Works great and etrailer folks did an outstanding job with quick turnaround and communication…thank you!
by: Darryl F02/11/2014
I had broken my factor connector on my 06 Tacoma, frankly due to a poor design placement by Toyota in my opinion, however I was not going to pay a premium $200+ price for a new OEM part and I wasn't planning to place it back in the original spot to only get broken again. This is a great replacement plus I no longer need a wire adapter. The unit fit perfectly in pre-cut hole that held my left tag light. Only had to drill 4 small holes for the bolts to secure to the bumper. Only pain was cutting the old wire and attaching it to the new connector, but that only took 10 minutes top.
by: Richard09/24/2023
Great product! Install on a Jeep for off-road with a trailer and so far so good!!!

This Hopkins 7,5, and 4-way trailer cord socket was delivered quickly and fits my needs for all my trailers. It came with all fasteners and complete instructions in the package and etrailer videos. I recommend this product and etrailer.com as a vendor.
by: Larry R06/09/2017
I ordered the Tekonsha Electric trailer brake control and the Hopkins connector. It met my expectations. And easy installation. I have ordered from etrailer several times and they are professional in every way.

This is my second one in a 10 yr timefr ame.
by: John S 01/12/2014
This seems to be a pretty nice plug. Makes it nice with the 4 way and 7 all in one. The lid has a pretty stout spring on it so it should keep the weather out. Fast shipping excellent service.
by: Patrick W.09/15/2015
Build quality seems better than the base Hopkins product I had used before. Installed it in a mounting box (18159) on my Curt round tube hitch.
by: Greg09/03/2013
The connector interfaces very well with my XC90 and there is no drilling or advanced skills needed. Everything went together very well.

Works good. Put it on my 1 ton project.
by: Vito Lotta - San Diego08/02/2014
I could not find a 7 round with a 5 flat connector anywhere in San Diego. Most of the people I spoke with at trailer shops or RV stores said no one makes it only with a 4 flat connector. I just kept looking because I needed one with a 5 flat for my boat and didn't want to keep using my adaptor.
I found etrailer and the rep I spoke with was very knowledgeable and said he had exactly what I was looking for and it was a great price. I will be always using etrailer for my trailer parts for now on.
Thank you,

great
by: Whitney T10/13/2017
It's a connector!
We got this connector to wire our small teardrop with an RV 7-blade for underway charging and reverse lights. It's well built, seals well when not in use, and does its job just fine. We did not lube the contacts, but so far no visible corrosion. The 4/5 flat connector is a nice bonus - keeps us from needing to carry along an adapter.
If you're installing it in a new location there are two things to remember: make sure you have enough depth at the installation point to allow wiring to run clear, and use a REAL bimetal hole saw if you're installing it in a metal bumper.
Would use again.
by: J.T. Swindle04/23/2019
This plug is awesome! Using the bottom 5 pin plug on the bottom plug works great on my utility Trl, the other plug I have wired for my other trailer with brakes, it definitely works great with no adapter's no matter what the trailer on mine I'm pulling, would definitely recommend this if you need a great plug!
by: Nuffsaid02/20/2019
This receptacle should come standard on all pickups and SUVs!! The seals keep out almost all of the water and grime. The spring-loaded cover acts as somewhat of a keeper for whatever plug is inserted in the large receptacle. The versatility of hooking up to old and new boat trailers, plus any equipment trailer the local rental yard can throw at me, is amazing! I still carry a couple of adapters, but never need them. Installation takes about 15 minutes. Be sure to use the included terminal grease.
by: Kirby06/15/2018
The Trailer plugin was a replacement for a cheaper one, that was mounted below the bumper, next to the tow hitch. This one is mounted in the bumper, between the license plate lamp and the license plate, out of the way of being damaged. Great plugin. ( but drilling the bumper was a pain, but worth every bit of time). This is my third order from E-trailer. Great Service and looking forward to my next order.
by: David R06/19/2018
Trailer light connector arrived in a reasonable time and is as represented. I will like the convenience of having both the flat and RV style plugs, but it does make the receptacle a bit bulkier than just an RV connector. For me, finding a suitable mounting location that will not put it as the lowest thing in back is often a challenge. I don't like making big holes in the bumper, esp. on my pristine old truck bumper. etrailer used to offer a connector box that secured to the hitch square tube with a hose clamp. I bought one for use on a motorhome and it worked well, but I could not find it offered any more.
