Most Popular 4 Flat for 2022 Hyundai Tucson

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)

Perfect . My new Subaru hitch has a flat plate to which the dealership attaché the 4-flat. I used “2 L-brackets” to accommodate the 90 degree bend of the adapter bracket.

This product works as expected. There is not too much to the installation, just plug it in properly and mount the ground wire. I did not find an easy way to mount this to my wife's Odyssey, or to the trailer hitch (item# 75270). Luckily, I do prototype design and manufacturing. So I came up with my own solution. I designed and made my own bracket to mount the 7 pole to the trailer hitch. It works like a charm, and looks great!

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.

Simple and easy to use; just plug it in and connect it to the trailer harness. Works like a charm!

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.

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.

Works very well after re-wiring trailer lights with waterproof distribution box.

Just what I needed for my home-built bike carrier. My wife rides an e-tricycle and by the time I loaded the trike and a couple of bikes on this platform, you could not see the car's taillights or blinkers. This harness worked perfectly!

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.

I just installed this on my 2015 Volvo XC70. I also used the Curt XC70 plug and Play for wire kit. I watch two of etrailers excellent insulation videos. Installing the hitch and both the wiring products took me around 3.5 hours. I think Curt products are great and they are reasonably priced! e-Trailer makes your DIY installations easy. You just need to take your time when removing interior panels and double check your work. I used Volvo's torque specs for the bumper parts when I installed the hitch. E-trailer doesn't stop with just hitches and wiring solutions, they have just about anything you need to load and haul overhead or behind safely. What about performance? E-trailers got you covered. If you get in a jam during the insulation, don't fret or worry, call the text at e-trailer and they'll walk you through it. I want to thank E trailer and their professional staff for helping me with my truck and auto towing and lighting solution for over 10 years now!

This was/is a critical piece of any towing system, and as such requires extra care to hook up properly . I would recommend testing each connection as you hook it up being extra careful to make sure you are matching the terminals in the mating connector properly. This harness/connector performs perfectly when properly installed.

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.

Just what I needed for a boat trailer rewire. It would be nice if two more brown wires were added to take care of the yellow tongue lights/running lights that are partway along the trailer. I will splice in.

I'm extremely satisfied with the wesbar 4way flat trailer wiring harness I purchased from etrailers.com. It was very easy to install with no problems. As long as you connect the wires correctly (example) white wire to white wire brown wire to brown wire you won't have any problems. If I ever need another one I'll know who to order it from etrailer.com.

Good solid unit that I expect to last a lifetime. I purchased this unit primarily to provide a charging port for a float charger. The idea being that if I forget about it or if someone else drives my truck and is unaware that it is connected, it will easily disconnect when the vehicle is driven away.

Perfect! I use the 4 flat for my boat trailer lights and the +12v I've wired to charge the boat battery as I drive to and from where ever I'm fishing; brilliant!

This is my second order with etrailer. Both experiences with your company have been very positive. The knowledge and friendliness -along with following up on orders and satisfaction have been much appreciated. Brittany, the customer representative, is a huge asset to etrailer.

Exactly as described and what I needed. Delivered quickly.

I have ordered several adapters and complete trailer wiring harnesses from Etrailer. All have been top quality. I have saved a lot of money on the plug and play trailer harnesses. Several hundred dollars when they are factory installed, less than $75 from Etrailer.

ETrailer had exactly what I wanted at a fair price. Website was easy to navigate and purchasing was simple. Shipping was fast and I was kept notified right up to when I received my order.

The very same part I had to replace but adaptor doesn’t have the actual 7 pole for center electric brake . It’s actually a 6 pin blade to a 6 pin round with a 4 pin boat style plug

Great product and received it quickly

I have been very pleased with etrailer orders recently. Everything shows up when expected and products are as expected. Attached are a couple before and after pictures of my recent project to add lights to a cargo rack per my wife's request. Thanks for the professionalism of all at trailer

Delivery was quick and electeical was just what I was looking for. Was able to mount bracket to hitch and running the wiring was easy with it all color coded. The single sheathed trailer plug was also what I was looking for and priced below anywhere else. Was very industrial and was almost an exact match to replace the existing one on my triton trailer.

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.

Used my 4-5 pin adapter to tow my 20 foot Mako to the ramp here in East Boothbay this past weekend. I am always pleased with the wide array of products etrailer stocks that help keep me on the road.

I bought this product a year ago. My car was wired for a 4-prong utility trailer and last fall I purchased a small 5-prong motorcycle trailer that I intended to pull with my very small car. I needed this adapter to make everything work correctly on both units. It's perfect. The folks at e-Trailer are always super helpful and they pointed me to this one right away, knowing exactly what I needed (I had no clue - I'm a novice!) Once again, both the staff and the product came through for me 100%.

Always a great experience

I have used etrailer probably four or five times now and have been very happy. Shipping is fast, prices are reasonable and the products are of good quality. I purchased more of the Quick Fix 4 Pole Trailer Ends - they work really well for the non-automotive industrial control project I am working on.

They even printed the light circuit on each wire , never saw that before !

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!

Ordered on line Hitch, Harness and associated items. Within a couple of day the large box was delivered. Installation Videos a plus. Install and pictures next, when it stops raining!

I am very pleased with the products and service provided by etrailer.com. The 4-way Curt trailer hitch wiring connector and Hopkins Adapter for my 2015 Honda Pilot were easy to install with the clear and well illustrated directions. They are performing as advertised with no additional troubleshooting required. The quality suggests that they are durable and will last for at least as long as I own the vehicle. I currently tow boat trailers. The car came with the OEM trailer tow bar (hitch) and basic internal trailer wiring. The etrailer.com parts were just what I needed to complete the package. [I suggest you include a note to install the provided 10A blade fuse in the holder on the S3 harness in the installation instructions]

The website was the first indicator this would be easy. Logically laid out, suggestions for complimentary hardware, good photos and demo video's to make selection easy. The ordering was easy, I received timely updates, who actually worked on my order and again, timely updates. Order arrived quickly and is exactly what I needed. No drama, just received my order promptly. What more could I ask for?

E-trailer: they've got what I need at a reasonable price. This is what e-commerce should be!
