Today, we're going to review part number 20135. This is the Tow Ready multi-plug OEM replacement harness. This kit will let you add a 7 way RV style trailer connector and a 4 way connector to your vehicle. It has the factory tow package. This is a custom fit part number. It is designed to plug into a Dodge, Chrysler, Jeep, and Mitsubishi vehicles, starting in the year 2000, that have the factory 7 way connector.
I would recommend this to go to our fit guide on our website, and you can put in your year and model of those vehicles, and it would tell you if this would be the correct part number for your application. This is a plug in, simple installation. There's no cutting or splicing required. This wiring harness, basically, will plug into your factor wiring at the back of the vehicle. The plug right here is extremely durable ABS plastic construction. It has a nice, oversized lid hinge right up here.
It helps keep out any dirt and moisture from getting to the terminals. It also has nice, enhanced weatherproofing. They do use seals on the cap itself, and the terminals are corrosion resistant. It does include the mounting bracket and the screws. They're all included. Basically, what you would do is, before you go and plug this in to the back of your vehicle, I would take your mounting bracket, slide it on.
Slide the four way also through there. Bring it all the way up, and you can see that it will line up. The holes on the mounting bracket will line up with the holes right there. At the very top, you'll see the holes for mounting it to the vehicle. Then, what's nice is, you'll see this little cutout on the side.
Basically, that's where you can just slide in your 4 way just like that. Then, plug this in and with this plugged in, this would be at the back of your vehicle. You have access to the 7 way, and then the 4 way, just like that. That should do it for the review on part number 20135, the Tow Ready multi-plug OEM replacement harness. .
Worked great on my Dodge Sprinter. Built solid.
Works great just make sure you have a wiring harness on your truck. But love the product.
iIt whole be better if the flange that attaches the assembly to the truck is made of metal ,this whold make more durable. I Have had two assembles fail because the plastic broke where it attaches to the truck.
Great ServiceI didn't have to purchase it from the dodge dealer so I saved a lot of money by ordering from E-trailer.com It arrived on time and was just what I needed to fix the problem.
Product is superior, the best 7 way that can be found it hooks right up to the wire harness easy as that hardware included is great.
Works exceptionally great. Great people at etrailer, shipping was fast.
little problem hooking up to trucks wiring harness due to plastic square
connector being bent out of shape on bottom a little able to reshape and hookup,connector is a lot better quality than original one that was on truck and has 7-way & 4 pole connections makes towing different trailers easier awesome! fast shipping great price! helped me avoid dealing with dealerships high prices and delays on shipping and getting wrong product, website was easy to order from and great description of connector with good quality photos will save on my favorites and pass on to friends thank you Ross
Exact same product that was in the picture arrived at my door, so the item was exactly as described. It plugged directly into my factory wiring harness on my 1998.5 Dodge Ram 2500 with a 24v Cummins. It did not fit on the factory mounting position, but mine was very bent anyway. So I cut it off and used the included mount. The self tapping screws that were supplied were not very strong, so I had to use rivets to secure the mount. But I was mounting it on the hitch receiver which is very thick steel, so it was expected. Overall, great product and works as it should.
Yes, this product works great. It plugged into the factory harness. I would recommend this product
This is a nice quality part I'm using to replace the OEM connector on a 2008 Jeep Liberty. I really like the way it has a four pole connector in addition to the 7 way connector which saves time and the hassle of finding the four pole adapter to plug into the 7 way socket. The OEM part that came with the Jeep was 7 way only. This is a great improvement. Fast shipping and super communication. Thanks!

nicely thanks
Still works great after one year. the plastic hasn't faded or broke either.
These people understand customer service. I volunteer with SCORE as a small business counselor / mentor and the people at eTrailer epitomize how customer services should be handled. I requested confirmation that the part would work for my truck even though it listed several years beginning with the year after mine. They researched and determined that only the bracket would not be the same which was not a problem for me. Excellent product. Excellent service. Excellent company.
Wonderful product. All I had to do was pop out the old wiring harness and plug in the new. Easy as that. Bought a travel trailer so need the 7 way, but have a boat which uses the 4 flat wire so problem solved. Happy camper and boater. Great price as well. As a ebay person I couldn't find a better deal. Now etrailer is bookmarked on my PC..
Great customer service experience! The notification and follow-up was excellent regarding receiving my order, shipping my order and delivery of my order. This particular connector was exactly as advertised and plugged directly into my 2005 Jeep Grand Cherokee Laredo's factory wiring harness. I had to make a few minor modifications installing the bracket but it worked out just fine.
Has held up really well. My vehicle had an aftermarket harness already installed, but the video on the etrailer site made fitting the new one in much easier. The instructional videos on this site are really fantastic.
Fast and easy shopping.
Had a small trailer I would always pull my dirt bikes never had trailer lights hooked up, which is illegal, I saw a product at etrailer for Only $29 bucks ,one two three clicks ,works imperfect. Avoid getting a ticket and for safety literally takes 5 minutes I would recommend hooking up your trailer lights
The trailer adapter that I received is the EXACT Factory replacement item at a very reasonable price. Much less than the dealer was charging for the exact same item. Thank You!
This was another great part from etrailer I installed it in just a few minutes on a 2006 dodge 2500 4x4
Exact Dealer Replacement Item. 2004 Dodge Durango Trailer electrical connector.
This product is genius! I no longer have to carry around an adapter for my utility trailer. It perfectly connected to my 2001 Dodge Ram and installed in less than 5 minutes. I have made several purchases from etrailer.com and I am more than satisfied.
Shipping was fast. Got the product in good condition. Plugged right in to the factory plug like it was supposed to. Should send some dielectric grease with it but overall very pleased.
Easy install in my OEM footprint. Makes it easy to use either kind of trailer connector. Can't lose an adapter you do not need to use!
Bought this for my 1999 Dodge Ram 2500 and it was a perfect fit. The website made it easy to find the right part for my vehicle and the delivery was quick and without delay. I would purchase again from etrailer.com.
Product was easy to install and a valuable addition to my truck. A well deserved upgrade to my trailer towing ability.
The best " plug n play " set up. The duo set up has made it easy to tow various types of trailers
