Video Transcript for Tekonsha Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 20135 Review

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. .

Still works great after one year. the plastic hasn't faded or broke either.

1998 Dodge Ram Pickup

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.



by:

Fast and easy shopping.



by:
2006 Dodge Ram Pickup

Yes, this product works great. It plugged into the factory harness. I would recommend this product



by:
2008 Jeep Liberty

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

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

Does this assemble connect to the wiring behind the left light assemble on the durango? want to make sure Im looking at the right thing. I need the entire assemble.

Patrick B.

7/23/2013

This does not connect behind the tail lights. It is designed for 2000-2008 Durangos that came with a Factory 7-Way. It will plug into a port or harness underneath the vehicle, near the rear bumper. If your Durango did not come with a factory 7-Way, There are 4 Pole flat harness systems that are designed to plug in behind the tail lights. Which one you need depends on the model year Durango. Use our Fit Guide to find out which.

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.



by:
2000 Dodge Ram Pickup

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..



by:

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.



by:
2005 Jeep Grand Cherokee

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.



by:

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!



by:

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



by:
2006 Chevrolet Silverado 2500

This was another great part from etrailer I installed it in just a few minutes on a 2006 dodge 2500 4x4



by:
2001 Dodge Ram Pickup

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.



by:
2004 Dodge Durango

Exact Dealer Replacement Item. 2004 Dodge Durango Trailer electrical connector.



by:

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!



by:
1999 Dodge Ram Pickup

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.



by:
2003 Dodge Ram Pickup

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.



by:

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.



by:
2003 Jeep Grand Cherokee

Good. Wasn't an exact fit on my jeep. I already had a bracket for the part on my car. Had to modify this piece to make it fit on the bracket already on my jeep. The plug was a good fit though



by:
2003 Dodge Ram Pickup

Product was easy to install and a valuable addition to my truck. A well deserved upgrade to my trailer towing ability.



by:
2008 Dodge Sprinter

The best " plug n play " set up. The duo set up has made it easy to tow various types of trailers



by:
Jeep

I don't know how to post a picture, but trust me, this thing fit my jeep perfect. it was easy to install, no hassles at all. the young lady on the phone was very helpful and was very familiar with the product. it was delivered in a couple days, and was half the price the jeep dealer quoted. this was my third order. I'm very happy with price, service, products. I give them my highest recommendation.



by:
1999 Dodge Ram Pickup

Hooked up in seconds and works great. I have the plug temporarily attached with zip ties until I decide on a permanent mount.



by:

Quick delivery received it in 2 days packaged great product seems to be good as i haven't installed it yet but extremely satisfied with customer service. Would recommend etrailer to anyone

  • Recommended Trailer Hitch Receiver and Other Parts to Tow a Trailer with a 2003 Jeep Grand Cherokee
    I'm not sure which hitch receiver you're asking about but there are three that fit your 2003 Jeep Grand Cherokee. We have a Curt Class III, part # 13051, the Draw-Tite, part # 75139 for a Class III or the etrailer # e92AR which is also a class III. The crossmember is visible on all of them. I've linked videos of these hitches being installed for you to take a look at. If you're going to be towing a trailer with your WJ you also need trailer wiring. If you have the factory tow package...

  • Trailer Hitch Recommendation for 2006 Dodge Ram Pickup
    The Draw-Tite # 75662 Trailer Hitch will work perfectly on your 2006 Dodge Ram Pickup. This trailer hitch is rated for a maximum gross trailer weight of 6,000 pounds and a max tongue weight of 600 pounds. This should be more than sufficient to tow the 5" x 8" trailer. However, if you ever plan on towing a heavier trailer, you will want to check your owner's manual for the maximum towing capacity of your vehicle. I have attached an installation video of this hitch on a 2006 Dodge Ram for...

    Hello Mitch, thanks for reaching out. The # 20135 Multi-Plug T-One Connector Assembly you mentioned is made for a 2008 Jeep Commander and will only fit vehicles with a factory 7-way connector. The factory plug should be located under the bumper on the driver side. Your Commander did come with the factory 7-way correct? If so, the plug should be there on the drivers side. If your vehicle did not come with the factory 7-way, the factory plug will not be present. In this case you will need...

    You can use the Pollack 7-Pole Trailer Socket, # PK12-707E, on your 2001 Dodge Dakota quad cab. Keep in mind, this is not an OEM replacement socket, so the wires will need to be attached to each terminal in the socket. I have attached a photo showing how this socket should be wired. It is important that you wire the socket by function and not wire color since vehicle manufacturers are not known to follow an industry standard color code.

  • Trailer Wiring Recommendation for a 1996 Jeep Grand Cherokee Limited
    Your 1996 Jeep Grand Cherokee Limited most likely came with either no trailer connection at all or a 7-way round trailer connector. If you have a round connector at the rear of your vehicle near the hitch that looks like the part # 20135 then you have a 7-way. To see if you have the connection point to install the wiring harness designed for factory wired vehicles (part # C55260) you will need to look on the driver's side behind the spare. You will see an access panel there. Open it...

  • Trailer Wiring Harness for an In-Bed Camper for a 2002 Dodge Ram 2500
    Trailer connector # 20135 is meant as a replacement for the factory 7-Way trailer connector on a 2002 Dodge Ram. If your truck did not come with a factory 7-Way then this connector will not work. If it does have a factory 7-Way then I think I have a better option for you since you need the connection to be more at the front of the bed for the camper. You can use a 5th wheel/gooseneck harness and connector, # HM42137. This will plug in line with the factory 7-Way wiring. Normally the connector...

This kit includes everything you will need for a 7-way and gives you the option for installing a trailer brake controller if you need one down the road.

    If your Ram has the square plug for the wiring harness, you could use the Multi-Plug T-One Connector Assembly, # 20135, to add a 4 and 7-Way connector. If you have a different wiring situation, to add a 7-Way and 4-Way trailer connector to your 2002 Dodge Ram, you will need to use # 37185. You will need to plug in the existing 4-Way that you have on the truck into the 37185. You will then need to ground the white wire to the truck frame. The purple wire is for reverse lights on the trailer...

  • Brake Controller Recommendation for a 2003 Dodge Ram with a 4-Way
    For converting your 4-way to a 7-way you will want the Brake Controller Install Kit and 7-Way Adapter part # 37185 and part # 3020-P. Brake (blue) wire does not run all the way back to the 4-pole at the rear; it stops at the connector that is located under the driver's side wheel well. In order to finalize the installation you must splice into this wire and continue it to the blue wire of the # 37185.

  • How To Determine if a 2006 Jeep Grand Cherokee has a 7-Way
    If you look at the back of your 2006 Jeep Grand Cherokee and see a wiring connector that looks like the Tow Ready Wiring harness part # 20135 then you have a 7-way. Another option you could have is a 4-way which would look like part # 18172, or you might not have any connector at all. To add a 4-way you would first want the Tow Ready Wiring harness part # 118394.

It will simply plug into the port you found behind the rear bumper of your truck and you would be ready to go.

    The Pollak 7-way/4-pole Connector you referenced, part # HM40975-11933 will indeed replace the existing 7-way on your 2006 Jeep Liberty. The only possible knock on this connector is that both the 7-way and the 4-pole can't be used simultaneously, as both the protective covers won't open at the same time. If that's not a problem for you, this connector would work just fine. The Tow Ready # 20135 would also be a fit, and both connectors could be used at the same time. I've linked you to...
