Most Popular 4 Flat for 1990 Jeep Wrangler

Got this for my 2017 Jeep Jk.... comes stock with only 4pin... need this for a small 6x12 trailer... works great ! Since taped into 4 pin only brakes and blinker works, but that's all I need...

I bought this so that I could adapt the four pole connector coming from my jeep wrangler to a 7 pole coming from my new TB camper. Had it mounted on my bumper and it works just great. Expedient delivery of item and great customer service on the phone.

2018 wrangler unlimited Sport S. Without trailer wiring. Completed installation today. Used a 4 flat along with a 7 pin converter. Works and fit perfectly. Very hot day and work slowly and carefully. Very satisfied . Great folks at etrailer. Great products, great quality and prices. I'm a several time repeat customer and couldn't be more satisfied. 4 pin harness Was a 56407 and the 7 pin adapter was a 37185.

Lacking instructions

etrailer rocks! Period. Great Web site, awesome helpful information and videos...and great service.....highly recommend them!

Product is top quality and arrived very quickly in excellent condition. 5 stars !

I purchased the 7-way cord and the adapter to extend the connection from the bumper to my extended hitch connection. The ready made molded cord made it easy to assemble the extension cord. Works as advertised.

Much easier to plug and unplug than the little four flat tight thing.

I always look forward to working with etrailer. They sell quality products and provide “old school” customer service...Thanks!

Works, exact fit, high quality, coils tight so max of about 3.5’ perfect! Heavy duty wiring, great waterproof connections.

This adapter is wonderful! It continues to work like a charm, was easy to install, and the price was right. Needed it for hauling my boat trailer that has hydraulic brakes. It has made it through all kinds of Wisconsin and Minnesota weather on my Jeep Wrangler and will last like any other wiring part that is exposed to the elements. I highly recommend this to anyone looking to adapt 4 pole to 5 pole trailer wiring.

Great product! I have a Jeep Wrangler Unlimited that only has a four pole flat connector. I have a boat thats needs a five pole because it has surge brakes. This was the perfect solution. I just had the fifth wire connected to the back up light and plugged this five to four pole adapter that was already on the vehicle. Problem solved. It came quickly. I accidently ordered two and I got a call from Etrailer questioning my order. I thanked them and said I only needed one. They saved me the cost of the second adapter when most companys would have just sent them both- and charged me for two.

The items I ordered will allow me to adapt my utility trailer for transporting my sea kayaks. Curt and Hopkins are both quality manufacturers. On a shipping note, the box arrived at the Post Office broken wide open. Your shipping folks need to wrap small, heavy, items in bubble wrap. Then stabilize it with foam peanuts. Just putting it in a box then stuffing the box with craft paper does not cut it. Items were not damaged so I am good to go.

I have now installed the following on my 2017 Wrangler: Brake light relay kit . Hopkins Towed vehicle Tail Light wiring kit. Blue Ox base plate. Blue Ox Patriot Portable RF Braking System. All of this has taken about 3 days of work spread out over a week or so. Overall it went well. Not too many surprises. Crawling around under a car at 71 is a bit of a strain but I'll get over it. I must say that Donna P. has been a wonderful source of great information and has stayed right on top of the process. eTrailer has been a great source for this project. I would recommend you all with no hesitation.

Installed: 9/12/2013 Jeep Wrangler Unlimited Installation of the plug was a quick and easy. The existing Warrior hitch has a tab on the side for a trailer wiring socket. Drill a new hole on the installation bracket (comes with the trailer connector) so the bracket on the hitch matches bracket on the trailer connector. Done deal. This is the only trailer connector I found which has the 7, 5 and 4 connector options. Flexibility is always a good idea when you are borrowing someone else trailer or renting.

the perfect plug for mt Wrangler tj

Quick ship, exactly as described. I buy from etrailer all the time

Good prices,free shipping($99.00+)good products as listed, what more can you want!

Product shipped quickly and was exactly as described. It mounted to my Wrangler in just a few minutes of work.

Quickly shipped and great value. Very easy to mount and saves time by having two plugs available and not having to switch when using round plug. Great seller and very good product.

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

Love the test option on this

Arrived fast just like I was told, and great product, simple install

The adapter works great! I used it the day that I got it. I have an 18' car trailer that I just needed to take down to get a VIN inspection and I wanted to use my Jeep Wrangler because it's so easy to maneuver the trailer. I plugged the 7 blade from the trailer into the adapter, plugged the 4 wire flat into the Jeep, connected the ground wire, and the lights and turn signals all worked fine!!!!

It took awhile to receive my order, but I was informed by e-mail and was kept informed when I should expect delivery. Luckily, was in no rush, so I would reply and wait for an update from you. i received the connector in good condition. Thank you!

Very good quality.

fits the plug perfect....just got a goldwing used, haven't had a chance to ensure it (the bike) was wired correctly for a trailer. no fault of the product, just wish its wireing was a bit long due to the way the plug was intigrated into the underside of the tour trunk.

Works great! Took a few minutes to figure out the rv side and get it set up so the round RV part Correlated in the correct way to the standard four flat wiring. But it went smoothly.

My '92 GMC Sierra had a 6-pin trailer harness connector and I'm going to be pulling a pop-up camper in a few weeks that has a 7-pin connector. I originally ordered a 47435 6-Pole to 7-Pole Trailer Wiring Adapter. After thinking about it for a day I changed my mind and ordered a HM48470 Hopkins Endurance Multi-tow 7-way, 5 & 4-wire Flat Connector to mount in the bumper and a HM47570 Hopkins Endurance Multi-tow Connect Adapter - 7-way To 6-way, 5-way and 4-way. The HM48470 will allow me to pull the pop-up as well as giving me the 4-wire flat connector that I need for my boat trailer. I bought the HM47570 adapter just to cover all the trailer wiring needs I might run into. I really like the fact that the 47570 adapter has the quick change plug to cover both wiring arrangements for 6-pin trailer connectors. I placed the original order Saturday evening and the second order Sunday afternoon. Monday morning, I called etrailer.com to try to cancel the first order and was told that both orders were already boxed and on the way the shipper. I had no idea that they had people there to pull and box orders on the weekend. I asked about returning the first order when it arrived and was told by Helen M that it would be no problem at all. I have been extremely pleased with my purchase experience with etrailer.com. Everyone I spoke with there was very knowledgeable and I will not hesitate to go directly to them for my trailer and towing needs in the future.

I needed an adapter for my electrical towing harness so the that I could use a 5-Way connector on my 7-WAY plug. On line, I found and ordered Item No. HM47570 "HOPKINS ENDURANCE MULTI-TOW CONNECTOR ADAPTER - 7-WAY to 6-WAY, 5-WAY or 4-WAY." When I received the product, I was really stoked, it was exactly what I needed and what I had been looking for! I tried it on for "size" as you might say and it's going to work like a charm. I will send some photos later when I'm done with the installation! No time right now. . this coming weekend! Photo 1&2 my connector; Photo 3&4 the new HM47570; Photo 5,6,&8 the light bar I wanted to install and the completed project. Thanks a bunch!

Worked out pretty good. Had a hard time figuring out just how to attach it. I ended up just zip tieing it. It was a life saver that I could pull the rear plug apart. Made it possible to slide part of the harness thought a tight hole.

Got this to replace the poorly constructed plug that came with the 7pin wiring kit. That plug broke at the spring hinge the second time I used it. Surprised that Hopkins didn’t include “Butt Connectors” though. Seems a little nickel dimeish. Had a good experience with Paul who refunded their price for the defective Kit plug as well as refunding the price difference for the wiring kit which had gone from $110 to $48. Overpriced to begin with but convenient. Paul did real good dealing with a pissed off Old Guy

I rewired my light bar for my boat trailer with the items I purchased. Before I built the the light bar, every time I used my boat trailer I would waste valuable sailing or fishing time repairing faulty lights. The do not last long when you submerge them in salt water. This light bar now version 3.0 have given little trouble over the years

Great product. Works well when I had a broken connection on my 4 way plug end on my light-up hitch cover I bought from y'all a while back. Always a happy customer. Thanks, George.
