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. .

Multi-Plug T-One Connector Assembly for 7-Way & 4 Pole Trailer Connector - 20135

Average Customer Rating:  4.8 out of 5 stars   (63 Customer Reviews)


by:
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:

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:
2006 Dodge Ram Pickup

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




by:

Product worked great as advertised. Simple install.




by:

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

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

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:
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:

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:
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:
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:

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:
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

I have not installed the product yet but I am hoping that the installation is simple




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:

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:
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:

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.

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




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:
2000 Chevrolet Silverado 3500

Shipping was extremely fast. Fit perfectly. Plug matched my 2000 Dodge 3500. I didn't want to strip and clamp wires and with this factory fit I didn't have to. ( and a flat 4way to boot. )




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:
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

    The trailer wiring harness part # 20135 that you referenced has been confirmed as a fit for your 2002 Jeep Grand Cherokee. You can check under the rear bumper of your vehicle to see if you can find the square connector that it is designed to plug into.

  • Factory Tow Package Left Turn Signal/Brake Light Circuit Not Working on 2000 Ford F-250
    There are separate fuses for the tow package wiring on your 2000 ford F-250. Under the hood in the power distribution box you will need to check the fuse that is in location 1. There should be a 7.5 amp mini fuse in this location. That is the one for the trailer left turn signal and brake lights. You can find the locations of all fuses/relays and their functions in the truck owners manual should you ever run into this problem again!

  • Installing Brake Controller in a 2003 Dodge Ram 1500
    You are on the right track. Since your vehicle had a factory 4-way and you installed a 7-way the brake output circuit has been partially ran on your vehicle. 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 back to the plug. I attached a picture that shows what the wire and connector you are looking for. I also attached a help article that details installing a brake controller...

    If you have isolated the problem to the 7-Way connector on your 2002 Dodge Ram 2500 then you will want to start off by looking at the connector itself. Check to make sure that there is no corrosion built-up inside; if you find any (looks green or white) then you will want to go ahead and clean it out. If your Ram has the OEM tow package then you might need to replace your connector if you clean it out but the wiring still isn't working. Tekonsha has their Multi-Plug T-One Connector Assembly...

    The Multi-Plug T-One Connector Assembly # 20135 that you referenced would be the correct part to add a 7-way and 4-way on your 2002 Dodge Ram 2500. It will simply plug into the port you found behind the rear bumper of your truck and you would be ready to go. If you have the factory tow package you should not need any additional relays unless the ones you have are damaged. We do not carry these.

  • Troubleshooting Right Turn Stop Signal Not Functioning on a 2000 Ford F350 7-Way
    The problem is somewhere between the 7-way connector and the wiring of your truck. You can try cleaning the pin on the inside of your 7-way. Corrosion or dirt on the pin can cause the circuit not to function. Even if it doesn't look that dirty try using some fine grit sandpaper to get the pin down to bare metal. Other places to check is the back of the 7-way. There might be corrosion there that needs to be cleaned. Also, check for exposed wire and fix as necessary. Aside from that you...

    Thank you for all of the details. It sounds like the problem may be on your pickup still. You mentioned testing the pins in the 1, 3, 7, and 11 o'clock positions but if you reference the attached photo you can see that the left turn/stop pin on your 2002 Dodge Ram 1500 should be the pin in the 9 o'clock position of your 7-Way. If you test this pin and find that there is no signal then you likely have a bad fuse or relay. In the online owner's manual it looks like there is a "Trailer Tow...

Since your truck came with a factory installed 7-Way trailer connector, you can use the Draw-Tite Fifth Wheel and Gooseneck Wiring Harness, # 20110. Instead of installing it in the bed of the truck, you would just route it to the back. I have included a video link that might help with installation.

You could simply cut the 4-pole off and wire the yellow wire to the left turn, the green wire to the right turn, ground the white wire and run the brown wire to the running light and jumper it over to the running light on the other side.

    I do have the wiring harness you need for your 2005 Jeep LIberty, however the harness you currently have that is designed for a 2008 Jeep Liberty will not work. This is because there was a generational change for the Liberty starting with the 2008 model year.
