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.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.
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.

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.
Always a pleasure doing business with Etrailer .. great products at a great price shipping is always fast and packed well .. Thanks !
William - 07/03/2021Works as intended
48hr standard delivery to Okla, that’s fast and efficient. Thank all of you guys and gal.
A good product easy to install
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.
Victoria B - 10/07/2019The PK12-707E Trail Plug works great! Everything functions as Day one. I would highly recommend the Pollack Product.
John - 03/18/2021Ordering 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.
Laura E - 02/25/2017 Jeff L - 01/28/2018I ordered this item because the current one in use was damaged by a bumper drag and needed a replacement. After removing the old receiver and installing the new receiver I then went to plug in my trailer to verify that the plug was working. When plugging in the male end into the receiver two of the blade terminals pushed out the back of the new receiver. I pulled them back out with needle node pliers and tried again but they pushed back into the receiver again. I ended up having to use the internals of my old receiver and putting them into the new receiver housing. I was fortunate that it worked in the new housing. I can't get too upset because this is a inexpensive product. The housing was OK but the internals were cheaply made. I will not purchase this particular item again. First bad experience with an etrailer product.
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
Jerry A - 04/18/2020they arrived and looked just like in the photo
This 7 pin has been on the truck for a year now and is working as I would expect it to.
As always products are excellent. And always delivered in a timely manner.
Bill O - 09/26/2020Well built, a replacement for the one installed in the bed of my pickup. Had to modify the depth to fit between the inner and outer wall of the bed.
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.
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.
Works great! Installed on my tractor in two locations to provide power to a trailer equiped with electric brakes..
Clifton - 03/23/2019So glad you guys at etrailer.com carry the Pollak brand. In my experience none of the others compare. And thank you for the great customer service and quick 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..
I can only rate for what I do - I buy the items for our company.
E-Trailer is very good to work with. Pricing is good.
Put this in the bed of my new truck. So much better than the Hoppy I had in the last one. Brake connection much better with this one. Should have known better the last time!!
Easy install, wire colors on plug do not match my truck. Other than that, it work as promised.
