Most Popular Trailer Connectors for 2010 Ford Focus

Part was exact replacement for the broken trailer electrical socket I needed, at a price lower than I expected. Vendor has a good catalog of just about anything I could need for my trailer and will be using eTrailer.com from now on.

Simple plastic cover. Does the job. Time will tell how well the plastic holds up in UV light.

Wiring worked perfect for my project. I replaced the wiring on my 14 foot utility trailer. If I was to do it again I would buy the next length up. I would have liked to have a little extra wiring if I was to ever need it.

Your sales staff is second to none. Keep up the good work. You shipped minutes after I placed my order! Very impressed! Marty

on time as stated

Replaced the wiring and lights on my 1992 boat trailer. I was able to get everything needed from etrailer. I think Optronics is of the highest quality and recommend both etrailer and Optronics product.

Routine trailer maintenance. Absolutely nothing worse than fighting trailer lighting or electric brake issues when traveling.

I installed this connector on my travel trailer. The original connector had become loose and would fall out if not retained by the tab on the bottom of the connector. After a year of usage The Pollack connector still snaps into place and fits tight. Good product.

Wiring and new self adjusting electric brakes were a simple install and work perfectly. The etrailer online video and written instructions made the job easy.

I needed a plug so I could pull my boat behind my camper. It was just the right length.

Great product no issues at all. Product as described & fit properly.

Pretty straight forward. I used it to switch my European trailer's connection to be able to connect to my Wrangler's 4-pin trailer hookup. No issues. works great.

Well I wasn't able to use this as there was no good place to install on my car without it practically dragging. Not a product problem at all. I tried to return and customer service was fast and super helpful... unfortunately return shipping would eat up any refund. So.. I get to keep it. good quality and product. Very happy with it and wish I could use it. Will keep it for sometime in the future when of course I will need it.

I bought this socket for my 2006 Volvo Xc90 to wire in the 4-Pole harness I also purchased from etrailer. Already had a few 7 Blade to 4-Pole adapters from my previous vehicle, and wanted the option of adding a trailer brake wire for a small camper later on so that was the main reason for the purchase. It also went very well with the Hidden Hitch I had already installed, bracket mounted right up to the existing tabs on the hitch. Super quick and easy install, as all of my etrailer purchases have been. Looks great on the truck, and functions great with the 180 Degree cover.

We just finished a makeover of our 1995 boat trailer. New bunks, sanded and painted but the best part of the project was the new LED lights from your company. They are so much brighter than the old incandescent bulbs that you really do feel safer driving down the road. We pulled the 20 year old wire out and replaced with new and used the 3M scotch loks to tie in. We were not sure the new style grommets would fit the old holes in the frame but they fit great. Your customer service was great, alerting me to a backordered reflector but recommended a replacement that worked fine. Patrick set up a Q&A page for me since I had questions about the best way to protect connections with dielectric grease, heat shrink and tape. Your website is one of the best with ease of navigation, complete pictures, great selection and thorough info, dimensions, etc. You guys really have your act together and also offer great value. I would not hesitate to purchase again and will recommend you when I can. I have attached a couple of pictures. Thanks for all your help. Wayne N.

Easy to install and works great.

I've had this in use for over a year and they don't build them like they use to. I use this on a gooseneck trailer and the piece of plastic behind the spade connector for the clearance lights and brakes has melted, allowing the spade connector to lose contact with the plug on the pickup. So the lights would cut off in the middle of the night and would have to wiggle the connection till I could fix it. I have an older Hopkins plug and never had this problem. To fix the problem I ended up putting pieces of thin copper wire behind the spade and have done it twice since the plastic melted a 2nd time and once again the trailer clearance lights would quit working. Attached are before and after pictures.

A great little heavy duty plug that I use to connect my car to the rv when towing 4 down.

I've never really liked Flat-4 type connectors. Unless you leave them dangling, they usually require that you crawl under the vehicle to connect them. (...Murphy's Law dictates that this will always be when it's raining or snowing). This Pollak 4-pole round socket, along with a Tow-Ready harness, and matching trailer connector, provides a neat, factory installed look, that's more convenient, and durable. My orders from etrailer arrived quickly, and with great seller communication. A+

Easy to assemble

I explained to Roger (I believe was his name) that I have a Blue Ox tow bar and base plate, The base plate was installed along with the wiring kit, but did not include the wire to go from the front of the grill to the interior of my Jeep to plug in my RVi brake, and this is what he sent me. I'm attaching a picture of what I have on my vehicle. Not only was it the completely wrong part, but it arrived in damaged packaging which I did not open. Please send return instructions.

Items were simply “thrown in the box” WITH the hitch which was not secured properly. Heavy hitch then bounced around on electrical connectors, destroying them. Components should have been fastened to the hitch as the hardware kit was with strong tape instead of just thrown into the box by somebody! Refund issued.

Wiring harness and flat tow bracket to be able to tow our new Wrangler behind our motorhome. Product arrived on time and everyone was most pleasent to deal with. had the bracket installed by the dealre we bought the Wrangler from as part of that deal and then did the wiring ourselves. Pretty weasy thanks to the excellent video provided by etrailer and it took us rookies about 3 hours to complete. we are very happy with the service and product. Thanks to all. Regards,

I had to replace the old 7 wire cable because the male plug had been pulled off. I chose the WH54006-043 coiled cable. I used a 1/2 inch clamp to hold the cable up at the box and a Connect-to-Protect to hold up the male plug. The result Is clean and tidy. Thank you,

This should work great, installation is still on my to do list.

Used this as the connection point for the Roadmaster diode wiring kit. Seems to be well made and will hopefully last a long time. I did spray paint it flat black so it blends into the front bumper of my “toad” a little better.

The documentation for wiring is limited and difficult to read without magnification. Otherwise this is well made and works perfectly.

This is the product I expected and it arrived in factory new condition. To no fault of etrailer.com the currier wagon train and the ox’en that pulled the load were heading East. This was not the direction they were accustomed to so it took a few extra days. All in all good job I will do more business with this company.

I wish than all trailer wiring was color coded the same. I have wired a lot of trucks ant trailers and trouble shot problems and always solved the problems. this one gave some serious thinking since the wiring was color coded different. But it is working and I do like the Pollak plug.

Only gave 4 stars because it was a bit confusing. I have a lot of auto wiring experience; from car stereos,amplifiers and all manner of accessories. All of the info on etrailer indicated that the color coding didn't match up. So I went into it disregarding the standard color coding, when in fact it was just as it should be.

Good thick rubber and plug works perfectly.

This is a great product. I use it for powering my electric boat winch with the truck. No more carrying an additional battery for the winch. When I put my Torquelift SuperTruss on, I have made an extension with this and have it on the end of the extension so I do not have to climb under the camper to hook up the power.

I am going to use this to power my new electric boat winch. I have not actually loaded my boat yet but in getting it all set up this plug will work perfectly. I made a mount that will hold both this plug and the 7 pin plug for the trailer. I was surprised as to how stout these plugs are, look like very good quality.

It is a direct OEM replacement, easy installation. What I liked most was a real person answered my call and took my order, Katherine was very polite and knowledgeable. Thanks again. CJ

Worked out awesome. I bought this for a buddy for his used truck. The previous owners for what ever reason took it. Plugged it in and worked flawlessly.

The plug was missing the set screw and collar that compresses on the cable to prevent strain on the connectors when removing the plug. You can see the set screw clearly in the product picture.

I like this style of plug because it is molded and is important in keeping water out of the plug. It is conveint because it has the right colored wires. I have a water tight termination box with studs that it is wired into. Once I damaged the cable so I opened up the terminal box installed eyelet lugs on the spare pigtail, and installed it in a fiew minuets. I keep a spare on hand with lugs on it so if I have an accident I can quickly replace it. I also use these on some of my smaller tow behind equipment. that's why I like this size plug it isn't real bulky.
