Establish a secure connection between your towing vehicle and trailer with this 7-pole, RV blade-style socket. Black plastic socket has non-corroding, shock-resistant interior design that eliminates shorting out and is color-coded to RVI standards.As the video indicates, ensure that your vehicle wiring is the same as the 7 blade definitions. Mine was not. Had to determine what color wire connections to use for a 4 flat adapter use on a dolly.
Service from erailer is always quick and efficient. The one time an incorrect product was shipped, the company beat a path to my door to get the right item into my hands. Every experience with them has been 100% positive. Great folks!
The convert in the trailer quit, I needed 12V ASAP and didn't have the wherewithal at the time to replace it. So, I mounted the socket on a piece of wood and hooked-up just the ‘battery-in’ (black) and neutral (white) terminals. I wrapped each lead around a couple of old fence post insulators. I clipped my battery charger to those. I plugged in the trailer and turned on the charger. Now the status display in the trailer shows the batteries charging. It saved me from exposing and charging the batteries in this rotten weather.
Installed this on my 2006 Jeep Wrangler Rubicon Unlimited, which never had one nor a kit to do it. I needed trailer lights, 12v power and brake control for a Coleman camper I pull. Has worked reliably for a year now.
Works like it is supposed too.
Just what I needed and at a great price
I ordered all the parts required to safely flat tow out 2017 Jeep Cherokee Trailhawk from etrailer.com. The only part they didn't have was the Mopar Flat Tow Enhancement kit Jeep requires to flat tow this model.
Ordering from them was great, the website is easy to use and I was able to locate all the pieces compatible with my specific vehicle. The expert recommendations help my decision choosing the right parts. I ordered from etrailer even though I found some of the parts on other websites a little cheaper. I chose to pay a little more because of all the effort etrailer has put into installation videos and guides. I was very pleasantly surprised to learn from etrailer that they have a price match guarantee!
So my equipment consisted of the following
Mopar Flat Tow Enhancement Kit (from Jeep)
Roadmaster Battery Charge Line Kit for Towed Vehicles
Mighty Cord 7-Way RV Style Trailer Connector - Trailer End
WesBarg 7-Way, RV-Style Connector w/ 6' Long Coiled Cable Trailer End
Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer Socket - Vehicle End
Hopkins Custom Tail Light Wiring Kit for Towed Vehicles
SMI Stay-IN-Play DUO Supplemental Braking System
Roadmaster Brake-Lite Relay Kit for Towed Vehicles
Blue Ox Alpha Tow Bar - Motor Home Mount - 6,500 lbs
Blue Ox Base Plate Kit - Removable Arms
Blue Ox Tow Bar Cover - Aladdin, Aventa LX, Aventa II
The installation videos are great but not all inclusive. Take the time to read the instructions that come with the parts. This is a major project, I took about 30 hrs over a full week but as you'll see in the pictures I took s few extra steps to make a cleaner look.
Some of those extra steps:
The base plate install requires the bumper be modified cutting off a flange on each side, I spray painted this to prevent corrosion.
In the install video of the baseplate on the drivers side they use an extra quick link (not included) to run the safety cable around the wiper fluid reservoir. I took the time to remove it and run the safety cable behind it.
I didn't want our nice new vehicle to look like it can be towed so I played the brake away switch and 7 way trailer plug behind the license plate, so when not being towed our vehicle looks great!
Some things to be aware of. The Brake air cylinder that mounts to the brake pedal with four bolts may need longer bolts, it did on our Jeep. Spend the money for weather tight heat shrink crimp fittings. The Hopkins wire harness was about 1.5 feet short to get to my plug location. Buy extra zip ties, electrical tape and split loom.
I recommend reading all the various installation manuals and watching all the videos because the various components integrate together and if you install one at a time you'll be doing a bunch of extra work.
The brake light relay is a real pain in the butt, not because of the hardware but because of the location of the brake light switch which is very hard to get to.
Overall I am very happy with the products and how the installation looks. We haven't towed it yet but do not expect any problems.
7 Pin Trailler ConnectorsI ordered the Pollak Black Plastic, 7-Pole, RV-Style Trailer Socket - Vehicle End, and the Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End to re-wire a Lance camper to vehicle connector.
I am going to adde the Vehicle End to the Lance camper and make a male-to-male pigtail that will plug into the vehicle and into the Lance camper.
The reason I am doing this is because I once forgot to unplug from the vehicle, and I ripped the wires out of the camper. The process to plug and unplug the wires is to back about 80% under the camper, plug in the connectors, then back the rest of the way under.
Once I rewire with the purchased connectors, I will be able to back all the way under the camper, preventing the problem of stopping at 80% both when loading and unloading.
The color coded Pollack connectors make the job of wiring easier.
I purchase all my trailer needs from eTrailer. Their service is always top notch.
Ordering process was very easy and my order shipped quickly. Ordered 2 of these and when I received them they were not the same. One was nice, the other (in my mind) was cheap and flimsy. I was happy with one and disappointed with the other. One I would have given 4 stars and the other one 2 stars. I would not order again unless I knew I was getting the nicer unit in the video I watched. I would also like to comment on the video and wiring instructions. I wired it like it suggested in the video, I had no clue there were different ways to wire a RV and utility trailer. The video and product page described RV wiring. Had to take it all apart and rewire it for my utility trailer. Crazy why they are not the same. My 2012 Ram truck, 2002 Dodge, and every trailer I have owned or pulled (no RV trailers) were all wired the same. etrailer.com assumes you are going to be using a RV I guess.

Thanks for your business and your review, Jeff. The connector is an RV blade-style trailer socket and is color-coded to RVI standards - we recommend testing for function before connecting.

The cover on the cheap and flimsy version broke after about 3 uses. I would not purchase this product again unless I knew I was getting the nicer version. The nicer version is doing great, no issues with it so far. I emailed the company about the broken cover, but I did not receive a response.
Perfect item if you run LED lights on your trailer and your vehicle detects bulb(s) out
Had my local service station mount it to the front of my RAM 3500. Allows Electric brakes to release when pushing boat trailer into storage using front of truck. Technician added a separate switch to active backup lights.
Works great.
Thanks

The part is heavy duty and a good replacement. The terminals are color coded, the green terminal turned out to be the brown wire. Check each terminal to verify they connected correctly. When I put the right turn Signal on, the tail lights came on and right turn signal was dim. Switched the brown wire to the green terminal and green to the brown terminal and worked correctly.

This is a common problem folks run into when working on 7-way trailer wiring. Traditional SAE wiring code uses a Green wire for the right turn and brake signal, while RV Standard wiring code uses Green for the tail and running lights. This PK12-707E connector is coded to RV Standard, while your vehicle uses Traditional SAE wiring. I have linked a help article with more information on these wiring codes for you.

Works great! Installed on my tractor in two locations to provide power to a trailer equiped with electric brakes..

Works great! Used connector on tractor to provide electrical output for electric brakes on a large utility trailer......
Exactly as described, exactly what I ne eded.
I purchased this as a replacement for the exact same model. Haven't installed it yet but will before winter strikes. I live in Michigan and typically get 5 - 6 years out of them before the door spring weakens and the innards corrode. The price is right so I don't mind replacing them occasionally. I use dielectric grease inside and lots of good electrical tape & wire loom around the external wiring. That seems to prevent corrosion, at least until the spring goes.
Not as easy to wire as in the video. Need to really make the wires short so will fit back inside. The wire (DW04914) did not want to slide back through the grommet and pulled it out. Had to lubricate to get it to slide through. I decided not use this product but opted to use the 4' Pigtail Wiring Harness to repair my 7-Pole RV Ford Socket. The wiring harness code is PK11998. It plugs in directly to my OEM Ford socket.
These connectors were high quality by a known manufacturer. I could have bought them locally but I wouldn't have gotten the expert advice and detailed information that I was able to get from eTrailer!. I talked to several people and each one was very knowledgeable. When the parts arrived, it surprised me because they came so quickly! I would readily order from them again if I needed more trailer parts. I used these connectors to adapt a Minn-Kota trolling motor to my fishing kayak and have attached some pictures showing it installed.
Several orders from etrailer. All have been accurate and delivered promptly.
I have ordered several items from etrailer over the years, from leaf springs, to tail lights, hitch receiver and connectors. Always happy with quality, price and speed of delivery.
I bought this and plan to hook it up to a PC power supply to make a test harness for a Habitat for Humanity trailer I am restoring for them. I had done the welding, but need to fix the wiring and put new lights on it before I put on the new deck. I don't want to tie up one of their trucks for testing it so I am making a tester (helps to be an EE). The unit was inexpensive, but appears to be very well made. I was surprised that it has a real cable strain relief feature at this price. I would recommend that once you have it installed, you fill in the end with epoxy or silicon caulking to keep water out if you mount it under the bumper..
The trailer socket received was exactly the right replacement part. It arrived very promptly and in perfect condition. It was helpful to have the tracking link so we could anticipate its arrival.
Note: be sure to mount the wires in the correct alignment, otherwise a fuse will blow or you will experience an electrical arc between the socket pin and the trailer pin. The two alignment screws on each side of the socket hold the wire harness in position; the harness can inadvertantly be installed upside down if you are not careful to keep track of the correct wire alignment.
Seems great. Time will tell

This heavy-duty trailer connector socket has an outlet for 7-way, 5-way and 4-way flat plugs. A weatherproof, insulated lid covers the terminals. The cover is also easy to open and extra-durable.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.
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.
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 !
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!
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.
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.
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.
I used this to complete the factory 5th wheel wiring in my 2015 Silverado 3500HD. Gives me a professional installation for my 5th wheel RV.
Great product! Install on a Jeep for off-road with a trailer and so far so good!!!
Great product fast delivery
This is my second one in a 10 yr timefr ame.
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.
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.
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.
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,

Easy to install, worked perfectly.
Good product. 5 pin cover could fit tighter, but over all makes trailer wire hook up easy and trouble free. No more searching for adapters.

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.
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.
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!
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.
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.

Still very happy with our purchase. We’ve towed over 10k miles and have had zero issues with our tow setup. I’ve shared my experience with several other RVrs and recommended your company for their needs. Thank you
