Pollak Black Plastic, 7-Pole, RV Blade-Style Trailer Socket - Vehicle End

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.327147

Exactly as described, exactly what I ne eded.1656671

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.

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

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.4129

Seems great. Time will tell 1651816

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.336452

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.

Harness worked well and these folks helped determine which harness would work on my Highlander. This was a great help. They replaced parts that was lost by ups due to the box was damaged. Great folks to do business with. Many thanks.1461972

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.

Works as described. I’m satisfied. 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! Used connector on tractor to provide electrical output for electric brakes on a large utility trailer......

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.103404

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.134476

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.800904

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..231684

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.14799

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.150860

In this case, the socket was required only because ours had literally worn out.
I only use original parts if possible for installation ease and quality expectations.
As always, etrailer had the correct part in stock and I received it in just three days.

etrailer is always my first stop when searching for hitches or supporting accessories...good service, fast delivery.487884
