T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector - 2003 Chevrolet TrailBlazer

Quickly and easily install a 4-way trailer connector on your Chevrolet TrailBlazer. This T-One typically plugs directly into the back of your factory-installed 7-way connector so you can retain the 7-way and also pull a trailer that has a 4-pole flat.

Features:

  • Provides a 4-way flat trailer connector at the back of your Chevrolet TrailBlazer to power your trailer's signal lights
    • Retains functionality of factory-installed 7-way, RV-style connector (if present)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points behind rear bumper
    • Plug in T-connector
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage: 7.5 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your Chevrolet TrailBlazer's wiring harness, which is located behind the rear bumper. If you have a factory-installed 7-way, blade-style connector, the T-One will plug in between the 7-way and the OEM socket.


Once installation is complete, the 4-way flat connector will be stowed beneath your Chevrolet TrailBlazer, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.

Video Transcript for Tow Ready Custom Fit Vehicle Wiring 118384 Review

Today, we're going to review part number 118384. This is the tow-ready T1 vehicle wiring harness with the 4 way flat trailer connector. Now, this part is designed to fit many Dodge, GM, and Nissan vehicles that have the factory tow package. I do recommend to use the fit guide on our website to help determine if it will fit your particular vehicle. This part will provide a 4 way flat trailer connector at the back of your vehicle to power your trailer's signal lights. Now, it is designed to tee into the factory-installed tow package. Now, on the factory-installed tow package, if you do have the factory-installed 7 way on the vehicle, what you can do is unplug the harness from the back of the 7 way, go ahead and plug this into the 7 way, plug the harness into this, and then that will give you the 4 way in addition to the 7 way.

In other words, it will retain the 7 way functions on the factory-installed 7 way, if you do add this into it. Now, on some factory tow package, they might leave off the 7 way at the bumper. So basically what you want to do is look under, behind the rear bumper, and you'll usually see where the factory tow package, wire, and harness will end, and then they usually have a cap on the end of it. What you want to do is take that cap off, and again, basically, plug this into the wiring harness, take that cap that you removed, and put it back in here, since you won't have the 7 way on your vehicle, and then you'll at least have the 4 way to the back of your vehicle. This is very easy to quick connects very quickly and easily. There is no cutting or splicing of the wires.

Basically, it is constructed of 16 gauge bonded wire. Now the 4 way, if you notice, does come with this dust cap that's connected. So, when you plug it in, when you're not using it, you can just put the dust cap on to protect it, keep it from corroding, or any damage to it. Now, this wire loom itself, if you stretch it out and measure it, it is about 36 inches long, and it does come with these instructions, which are very good, and they also have some good pictures to show you how to connect it. That should do it for the review on part number 118384, the tow-ready T1 vehicle wiring harness with the 4 way flat trailer connector. .

On my 2012 GMC Sierra, this was the best way to retain the 7 pole factory connection and also have a 4 pole connection. This product lets me have both 4 and 7 pole connections available at the truck, all the time, without adaptors to carry around. Most of the light trailers I pull have the 4 pole connection. I don't use the factory 7 pole very often. Installation is about 2 minutes. Check out the video on this product, it's very helpful.38140

This was a very simple harness to install. Appears to be very good quality. Saves you the time of having to splice a 4 prong connector later. I coupled this with the twist in 7 prong to replace the "dummy" plug on my 2007 Sierra. The whole process took about 15 minutes. Well worth the money. The hardest part of the whole install was hiding/tying up the wires.116589

I am very pleased with the T-0ne 4-pole flatTrailer Connector #118384. This is what I have been looking for months. The whole connection and wire-tie's support took me fifteen minutes. The longest time, 10 minutes, was spent supporting the extra cable to the frame with wire-ties. eTrailer is definetly on my browser favorite list! 112712

Took me all of 30 seconds to install this product. I'm using it for an additional 4 prong plug to attach a tailgate bar from Recon. Was also able to attach the reverse, and power lines with just a quick cut and splice. Now if I remove the tailgate bar, I can remove the wires, in seconds. 80554

Received complete order and was very well packaged. It was a one man job and took me about 1 hour to install the trailer hitch receiver. Most time was consumed because of rust in screw holes. I also ordered the wrong wiring harness. I called and a replacement is on it's way along with return information to send wrong harness back for credit. Thank you very much. 79656

Perfect fit on my 2012 Jeep Grand Cherokee. Hitch and wiring harness installed in 20 minutes. This is my fifth hitch and wiring harness purchased thru etrailer and have yet to be dissapointed. Both the video and written instructions were spot on, the installation of the wiring harness couldn't be easier!34414


Comments

Just did this install on a 2011 Jeep Grand Cherokee everything is just like the video. But the only thing that worked was tail lights. No turn or brake lights. I could not find any fuse or relays bad or missing. Did I miss something?

Part # 118384 is designed for Grand Cherokees with a factory tow package. Without the factory tow package, not all functions will work. In order to make it function, youll need to head to your dealer and have them re-flash either the Body Control Module BCM or Power Control Module PCM to fully activate that port.The other option is to use a harness designed for Grand Cherokees that dont have factory tow packages like part # 118425.

I actually ordered one of the wrong items. It was not your fault but my inattention. Your company was easy to deal with and delivered quick. I ordered the Draw Tite Trailer Hitch. I installed it by myself and it took about 30 minutes and bolted right to the frame and all the necessary hardware was there.32081

etrailer.com had the best price around on this wiring kit, their site was easy to navigate and they upgraded my shipping from 5 to 7 days to 3 to 5 at no extra cost to me. The tracking info page was updated frequently and the map feature was a nice touch. The package came in and we were able to hook it up in a matter of 30 seconds, great fit and works perfectly with the trailer. Overall I'm very happy with my transaction with etrailer.com and would not hesitate to order from them again.22454

the trailer hitch adapter I bought for my GMC truck was just what I needed to attach an LED lightbar below the tailgate and still have a plug for a trailer. There was a short in the plug but it seems to be working ok as I just bent the wire and wiretied it in place to keep it working. The shipping was prompt and rapid and much appreciated17257

  • 4-Way to 7-Way Wiring Adapter
  • The 4-Pole Trailer Adapter for GM trucks with Factory 7 Way, part # 118384 would give you a 4-way plug, but to get the 7-way plug as well you will need a 4-way to 7-way and 4-way adapter, part # 37185.

  • How Does the Factory Connector on a 2006 Chevrolet Silverado Pickup Work
  • The 4-Pole Trailer Adapter for GM trucks with Factory 7 Way, item # 118384, does not operate a 7-way connector. This item uses the vehicles factory wiring harness which can power a 7-way connector and adapts it to a 4-way connector only. If you want a 7-way connector at the rear of your vehicle you can use, part number 30955 which will give you a 7-way connector and a 4-way connector at the rear of your truck that will be wired from the factory connector that is located above the spare tire.

  • 7 to 4-Way Adapter for 2010 Buick Enclave w/ Factory Tow Package
  • If your Enclave has the 7-Way connector that has the factory harness that plugs into the rear of it, the 4-Pole Trailer Adapter for GM trucks with Factory 7 Way, part # 118384 will work great for you. Another option would be to use an adapter that would plug into the front of the 7-way, like the 7 to 4-Way Adapter with Tester, part # 47345.

  • Trailer Lights Not Working When Using Tow Ready Wiring Harness, # 118384, On 2007 Nissan Titan
  • The Tow Ready Wiring Harness, # 118384, is for a Nissan Titan with the factory 7-Way trailer connector. It will plug into the back of your 7-Way on your vehicle and the other end will plug into the tow vehicles trailer harness connector, behind the bumper on the drivers side. This harness does not come with relays because they are usually installed already when the factory 7-Way is on the vehicle. You might check the accessory fuse block to make sure you have the three relays installed that a

  • Boat Trailer Pulled by 2001 Chevy 1500 Has Lights That Will Not Work When Brakes are Applied
  • I would suspect a poor ground connection on the trailer. Most trailers use a ground connection at the front of the trailer, with each lamp picking up its ground connection by its physical contact with the trailer frame, in effect, using the trailer itself as part of the ground circuit. Take a look at the grounding point for the trailer connector, it can usually be found on the trailer tongue near the coupler. Make sure that this ground connection is tight, and connected to clean metal. If the

  • Installing the 4-Pole Trailer Adapter # 118384 on a 2010 Chevy Avalanche
  • The 4-Pole Trailer Adapter for GM trucks with Factory 7 Way, # 118384, is meant to plug in line with the factory wiring and provide a 4-Way flat connection. The 4-Way will provide left and right turn signal functions, brake light functions, and running light functions. The reverse light circuit will not be used or needed. I have included a link to the installation details below. If your 2010 Chevy Avalanche does not have a factory connector, you can add a 7-Way by using Twist-in, 7-Pole, RV-S

  • Troubleshooting Trailer Running Lights Not Working Using a 7-Way to 5-Way Adapter, 2008 GMC Yukon
  • You will want to make sure that the 5-Way portion of the adapter is pinned out to match the 5-Way on the trailer. You will need a circuit tester like the Quickee # 3808. Test the adapter when it is plugged into the 7-Way on your 2008 GMC Yukon to determine which pin is for the running lights. Then make sure the corresponding pin on the trailer side connector matches. If not, you will need to re-pin either the trailer side connector or the adapter to match. If there is no signal at the adapte

  • Where is the Connection Point For Trailer Wiring Harness # 118384 on a 2011 Jeep Liberty
  • The Tow Ready Custom Fit Vehicle Wiring, # 118384, is designed to fit if your 2011 Jeep Liberty already has a factory 7-Way and you want to replace it with a 4-Way. The connection point is located behind the factory installed 7-way trailer connector, or up by the spare tire of the Jeep Liberty (GM Jeep Liberty only). I have included a link to the installation details for reference. If your Liberty did not come with a factory 7-Way trailer connector, you will need to use Draw-Tite Custom Fit V

  • Troubleshooting Running Lights Not Working on a 2008 Chevrolet Silverado after Installing Wiring
  • I would start troubleshooting at the connector itself. Take the connection apart and make sure there are no bent pins or corroded terminals that could cause the tail light function not to work. Next, I would check the fuse block under the hood of the truck. There should be a slot for a tow package fuse in there. Check the legend under the fuse block cover and you may find that this fuse is missing or that it has blown, and needs to be replaced. Finally, check the connector at the rear of t

  • How Does the 4-Pole Trailer Adapter # 118384 Install on a 2011 Toyota Tacoma
  • The connection point is located behind the factory installed 7-way trailer connector. You will simply unplug the connector that attaches to the back of your factory 7-way connector. I attached installation instructions for this product below for you to check out. The 4-pole trailer connector will be stowed under the vehicle close to the trailer hitch. A mounting bracket is recommended. For that I would recommend a Mounting Bracket 4-Pole Flat, part # 18144.

  • Can a 4-Way Flat Trailer Wiring Connector be Added to a 2010 Chevy Silverado
  • A 7-way will have a round socket and blade-style pins in it. The 2010 Silverado would either have a 7-Way connector or no connector. If the connector is present, use a circuit tester like the Quickee # 3808 to test the function on the pins while someone sits in the truck to turn them off and on while you test. If there is no connector, you would need to install # PK11916. All of the wiring will already be present, you would just need to plug this connector in. If you wanted to change it over

  • Can 4-Pole Trailer Adapter, # 118384 Be Used at the Same Time as Another Connector, 2010 Dodge Ram
  • The 4-Pole Trailer Adapter, # 118384, is a T-style connector. When plugged into a truck that has an existing factory trailer connector, that factory trailer connector will remain functional and you will be able to use either one. However, I advise against using more than one of the connectors at the same time. Doing so can overload the circuits and cause electrical damage. I have included a link to the installation details for this harness for you to view. The harness itself is rated for 7

  • Attaching a 7-Way Trailer Wiring Harness to a 2000 Oldsmobile Bravada
  • It sounds like your 2000 Olds Bravada did not come with a factory installed 7-Way wiring harness. The Tow Ready Custom Fit Vehicle Wiring, # 118384, is designed to plug in line on a vehicle that has a 7-Way wiring harness already installed on it. It then provides a 4-Way wiring harness. It could still potentially work but you will need to make sure that the white wires are grounded to the vehicle frame in a spot that is clean and free from corrosion. A better solution would be to use # 37185

  • 2005 Nissan Titan Trailer Lights Not Working Using Tow Ready Wiring Harness
  • If your 2005 Nissan Titan came with a tow package and a factory installed 7-Way trailer connector then it may be easier to use a simple adapter, like # PK12716, to go to a 4-Way. If your truck did not come with a 7-Way at the back, then you would probably need to add some relays, # C57000, to make the wiring fully functional. The relays are required for trucks that did not come with a factory tow package.

  • Troubleshooting Trailer Lights When Trailer is Connected to 2004 GMC Sierra 1500 4X4
  • It sounds like a problem with the ground or wiring on the trailer, but it would be wise to check all of the components in your wiring system. You can test the trailer connectors on the 2004 GMC Sierra and the trailer with a circuit tester like the Quickee Tester, part # 3808. I am including a link to a FAQ page on trailer wiring that will show you the functions of each pin on your connector, depending on if it is either a 4-Way, 5-Way, 6-Way, or 7-Way.

  • Multi-tow Trailer Wiring Connector for a 2007 Chevy Silverado Classic
  • We do have a multitow connector that will fit the 2007 Chevy Silverado Classic. It has a 7-Way and a 4-Way, but not a 5-Way. It is part # HM40975. I have included a link to a video showing a typical installation. The other option is to use an adapter, # TC-127, that fits into a 7-Way and has a 7-Way, 4-Way, 5-Way, and 12 volt accessory inputs. I have included a link to a video review of the adapter for you.

  • Adapter to go From a 7-Way or 4-Way on a 2007 Chevy Silverado Classic to a Trailer 5-Way
  • I would be glad to help you out with an adapter for your 2007 Chevy Silverado Classic. If you have a 7-Way trailer connector on your truck, you can use something simple like # 37385 which goes from a 7-Way and provides 4-Way and 5-Way flat connectors. If you have a 4-Way flat on the truck, you can use # 20036. The extra blue wire would then be connected to a reverse light circuit behind one of the tail lights and used to operate an electric reverse lockout on a surge brake coupler. If the

  • Grounding Problem on RV Towed by 2004 GMC Sierra
  • The fact that everything pretty much works fine until the headlights are switched on tells the story. What you are experiencing is the classic symptoms of an insufficient ground connection. When the headlights are switched on, the wiring system of the trailer is drawing full amperage, which is when a problem will manifest itself. Make sure that the ground connection on the RV is securely connected to clean metal on the trailer frame. You can find this connection by tracing the white wire
