Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector
I received this purchase and was installing it the next day. Luckily I read the other reviews and saw that I HAD to attach the white ground cord that was sticking out of the harness. Upon looking, I found the white wire that comes out out of the flat 4 plug isn't attached to anything thus requiring the ground to be attached to the vehicle. All in all, I was very satisfied with this purchase.
Fit right, plugged right into existing wiring harness, worked fine.

Adapter 4 Pole to 7 Pole and 4 Pole w/Test Lamps
Not too difficult to install, but I would recommend using a car lift so you don't have to work from your back (review includes wiring harness and Brake Controller)
Very easy install. My truck had a precut hole in the bumper for the plug. I then hooked the spare 4 pole plug into a Reese Universal mounting bracket and mounted it onto the hitch.

Adapter 4-Pole to 7-Pole and 4-Pole
Really nice trailer wiring adapter. Very easy install. Takes about 30 minutes with all the tools needed. Drill, 7/64 bit for pilot holes to mount the bracket, flat blade screwdriver and 11/32 nut driver and two #10 self tapping metal screws with locking split washers and a couple zip ties to tidy up the wiring harness.
This is a great adapter to retro fit connections on my 2011 Expedition. Simple to instal and great support from etrailer.com.

Hopkins Endurance Multi-Tow 7-, 5- and 4-Way Flat Trailer Connector - Vehicle End - Ergonomic Design
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.

Hopkins Tail Light Converter with 4-Way Flat Trailer Connector
I used the Hopkins 3 to 2 converter to make a 6-pin round to 4-flat connector for my Winnebago View motorhome. While there are 6-4 plugs available to do this, they do not work on the Winnebago View (no brake lights). This adaptor works great.
This device was no help in connecting my five wire trailer to my four wire goldwing. I ended up having to use a number of diodes in the trailer wiring to make everything work properly. My trailer had red LEDs that were used for Brake, Turn & stop and I had to get the brake and turn function to share the same lead on the light fixture.

Pollak 7 Pole to 4 Way Connector Adapter
This product has been great. I purchased the multi-pin trailer wiring kit, and 4-pin adapter plug. By also purchasing the vehicles specific wiring harness, instalation was quick and easy! I chose to mount this through my bumber, instead of using the included bracket for a more factory finished look, and to avoud ripping off the mount while on rought terrain. This system works great and is much more affordable than factory parts. I highly recommend!
Everything worked out well. On time and fits perfect. Attach hitch setup and my new Ridgeline. It comes with a 2" inch receiver and I have a full compliment of 1.25. stuff from my previous car. All from etrailer i must admit! so I needed the 2-1.25 reducer, a good lock, and the 7-4 reducer for my goodies! Thanks for the grest service

Pollak Black Plastic, 7-Pole, RV-Style Trailer Connector - Trailer End
Seems to be a well made product that should make it easily replaceable for me. The usual excellent delivery and service from etrailer that I have come to expect.
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.

Curt Universal Installation Kit for Trailer Brake Controller - 7-Way RV - 10 Gauge
I ordered this wiring kit for a 2003 Dodge Ram 1500 I recently acquired. The Ram was not tow ready but did have a factory 4-way. I also ordered hitch #13333. The wiring kit is very high quality and was easy to install. The 7-way fit perfectly where the factory 7-way would have gone. I'm using a Tekonsha Prodigy RF wireless brake controller so the blue lead was not needed but I left some extra should that change. Thanks etrailer!
Arrived on time and installing now

Hopkins Heavy-Duty Trailer Coiled Wire Adapter for 7-Way to 4-Wire Flat
Works, exact fit, high quality, coils tight so max of about 3.5’ perfect! Heavy duty wiring, great waterproof connections.
Needed a longer connector for my vehicles. Both have 7 way plugs, but I use a trailer with a 4 flat plug. The coiled adapter works great for both of the vehicles. Very good product if you need some extra length and the fact that it has the coils makes for a better appearance.

Adapter 4-Pole to 5-Pole Trailer Wiring Adapter - Shorter
Arrived quickly. I didn’t need to wire the extra lead to my reverse lights because my trailer doesn’t have surge brakes or backup lights. Simply plug and play.
Perfect for converting 4 wire Ford Expedition trailer harness and boat trailer to 5 wire. The Expedition had a backup wire run to the area of the 4 wire plug so made the conversion easy.

Tow Ready 4 Pole to 5 Pole Trailer Wiring Adapter
Not installed yet but looks as good as one used before in a former vehicle. The actual adapter I received is "Reese", which is a reputable brand for towing accessories.
Good quality and everything needed for install in my 2006 Honda Odyssey. Now I can easily tow with either a 4 wire or 5 wire since the harness retains both.
# 12
Adapter 4 Pole to 6 Pole and 4 Pole Trailer Wiring Adapter
This adapter really cleaned up the installation and connected directly to the wiring harness. Maybe added an additional 20 mins to install this adapter but totally worth the time and money.
II use it on my towed vehicle behind the motor home. It allows me to take motor home power to a trickle charger in the towed vehicle and connect to the towed vehicle wiring. The four prong receptacle provides outlet to be used if there is ever in need for a four prong fitting good.

Hopkins Endurance 7-Way Trailer Connector Socket - Vehicle End - Ergonomic Design
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.

Pollak 7-Pole, RV-Style Trailer Connector Socket w/ Wiring Harness and Mounting Bracket
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.

Hopkins Endurance 4-Way Flat Trailer Connector w/ 48" Harness and Ergonomic Pull
Hitch for 2018 EcoSport SES. Easy to install and looks good. Wire end with cover also looks good
Product was awesome. My last two connectors have corroded so bad within a year that I constantly was having to take a wire brush and clean off the pins to get good contact. I'm waiting to see what the environmental cap does to eliminate me having to do this. Also bought the vehicle side. Would highly recommend this to anybody with a trailer hook-up. Only thing I would suggest is to make sure anybody purchasing also buys the splices since none come with the product. All in all, a great buy. Thanks!

Hopkins 7-Way Molded Trailer Wire Connector - 11' Long
Love the molded design, notice the wires are different colors from standard trailer wiring, but work great.
Installed a Hensley Hitch on my travel trailer and needed to extend the connector due to the setup. Superior quality. Wired directly to the junction box and junked the old pigtail.

Hopkins 4-Way Flat Trailer Connector w/ 48" Harness
SMI Stay in Play Duo installation in 2015 Jeep Wrangler Unlimited – Packaging was great with everything needed included plus extra items for various installation methods of you’re choosing. Upon initial investigation and survey, everything except the CD Information pack was accounted for. No big deal, as I had previously watched 2 different Youtube installations found on the internet. In fact, the internet videos were what I used as my step by step installation process, and the written instructions were only used for concerns where the video may not have been as clear as I had hoped for. Understanding that everyone has their own style and methods for doing this project, I purposely was not in a hurry to rush through it. All in all, I took @ 8 hours to install the Adapter 4 to 6 pole #30637, the EZMount Tow lights Kit, and the Stay in Play Duo Braking System. I choose the EZMount because I didn’t want to mess around with the OEM taillights and wiring. Magnetic lights don’t work so well on composite tops and I didn’t want to stick them to the sides of te Jeep, so I modified the EZ mount to wrap around the thickness of the rear glass hatch on both sides. I added a 2”x 4” pc of Velcro on the inside of the glass hatch and the mating surface of the plastic light housing - to hold the lamps in place until the rear gate was closed. I ran the wire harness on the inside under the trim all the way up to the front and through the grommet in the firewall. The flat 4 wire was routed and secured up to the Adapter 4 pole to 6 pole that I had fastened to the Blue Ox base plate. The actual installation of the SMI unit and assorted parts went rather smoothly. Most difficult issue was the lack of working space in front of the driver’s seat area. Installing the screw that holds the G force controller on the front (the side towards the front of the car) was difficult as it was almost a blind installation due to lack of room. The nut and fender washer used through the fire wall for attaching the air cylinder cable bracket was a challenge to reach - tight fit with not much room for one's hand and arm. Other than that, no big surprises – just a lot of tedious steps to do when you want to be sure that it is being installed properly – take your time and don’t be in a hurry. Once everything was installed – it all worked when I checked the system out. The only thing that may seem a bit odd is that when setting the G force initially, the compressor will shut off while adjusting per instructions. To do this initial adjustment, the wife stepped on the brake in the Motorhome, with the switch “On”. The compressor starts, and the brake is pushed down by the Air Cylinder, at which time I slowly adjusted the G force until the compressor shuts off. I secured the adjusting bolt and I told the wife to take her foot off the brake and then re-apply them. The compressor did not start again and the air cylinder did not apply the brakes in the Jeep. After setting the G force per instructions, the unit didn't turn on when the brakes in the Motorhome were applied - but since we were not moving - all I can assume is that the brake system will function while slowing down once the accelerometer setting (the sensitivity setting on the G force box) has been met. I assume that the sensitivity setting method includes a way to ensure the Jeep brakes are not engaged too frequently and only until needed. This is the only step that is a tad bit confusing without an explanation as to what to expect once the G force sensitivity is set. Lastly, I checked the brake away switch and it turned the compressor on and applied the brakes as expected. Overall - the installation went rather smoothly. Can't wait to see how the product works once we hit the road. I'll check back and provide an update later.
looks okay.

Hopkins 4-Pole Loop - 12" Long
Perfect product for my needs. My 4 pin is hiding under a cover on my bumper, so I used this device to plug into the vehicles 4 pin and allow the extension to hang below the bumper. Now I can quickly plug in to the adapter without taking a panel off. Cheap easy fix for a great deal of convenience!
I had purchased a Pro Series Cargo Carrier 63153 and the 20174 light kit. Assembly was very straight forward but I found that the 4-pole connector harness was too short. This 12" extension was perfect. Also, Jonathon at etrailer provided excellent customer support getting it to me while on a trip.
