  • Connects quickly and easily - no cutting or splicing of wires

    • Plug in T-connector
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


  • Maximum amperage: 7.5 amps per circuit

This custom-fit T-One connector plugs into your Chevrolet Impala's wiring harness, which is located behind the passenger's-side tail light. You will have to remove some carpeting and the tail light assembly to access this harness.

T-One Connection Location Points Behind Tail Lights

Once installation is complete, the 4-way flat connector will be stowed beneath your Chevrolet Impala, 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 Trailer Wiring Harness Installation - 2012 Chevrolet Impala

Today on our 2012 Chevy Impala we're going to install tow ready T1 Connector part number 118417. First we are going to need to access the rear cargo area. Then our first step will be removing the rear threshold. There are a couple of fasteners that will need to be removed first. Now we are going to get our trim tool or a flat headed screw driver to get underneath the threshold and just pry it up. There's several plastic fasteners underneath threshold still holding it in place.

Once we have it free we can go ahead and take it out and set it out of the way. Now we need to remove the passenger's side tail light to access the wiring. We'll remove the cargo hook here first. This will allow us to pull the cuffing back and access the other two fasteners holding in the tail light. We can go ahead and remove the passenger's side tail light.

With the tail light removed you can see we can now access the rear tail light wiring. We'll match identically with our tow ready connector. Underneath there's a locking tab that you'll need to press as you release the connector. Then we take our toll ready connector plug it in-line with the manufacture's. Now as you press them together securely locking them in place.

Now with the connections made we can take the other end of our four-pole connector we are going to run it down between the bumper cover and the sheet metal of the vehicle. Just down and over to our hitch. The white wire with a ring terminal preassembled with our ground wire. We'll take our self-tapping screw and run it directly into the sheet metal. With our ground wire is secured we can go and reinstall the tail light line assembly and into your trim components.

Now with the interior trim components reinstalled we can go ahead and get up under the vehicle and round our wire over to our hitch. Then I'll take some black zip ties and secure the wire to the top of the hitch. After I secure my wire I'll just take my pliers side cutters cut off the excess from the zip ties, clean up the install a little bit and that now completes the installation of our new tow ready T1 Connector part number 118417 on our 2012 Chevy Impala.

2008 Impala wiring harness, unsnarled the wiring of my trailer to the car. I had poked hole with my test light and could not get it total working correctly, sought a solution and googling found this etrailer had the wirng harness at a good price for the non-soldering hook up of the car lighting, brakes, turn signals all to the 4 wire connector. same as the trailer had. No problems, removed the tail light as the videos showed and unplugged to plug this harness in and ...done...simple and easy. My sincerest thanks ! 42546

Ordered a hitch and wiring harness form etrailer on a Tuesday evening and received it on Friday of the same week. Since my order was over a certain amount, I received free shipping. I was informed when my order shipped that etrailer had upgraded my shipping again, at no cost. This in my opinion is what customer service is all about. My order was correct and the hitch is first quality and installed easily. I would highly recommend using etrailer and certainly will in the future. 99084

I would recommend just watching the website videos a couple of time through for the installation instructions for this item if they are available for your vehicle. It was so very easy to install. I might have spent no more than 15 minutes to do it and that would include encasing the wires in some protective harness tubing too! It couldn't be any easier unless you had someone install it for you. 36855

The T-One wiring harness for my 2006 impala was just as described. I am not that mechanically inclined when it comes to wiring, but I was able to install this product in less than 30 minutes. And that was taking extra time to make sure the wires did not come in contact with the frame to rub the wires.My product arrived in just a few days. Just in time to pick up my new trailer! Thanks for a GREAT product. 182012

  • Bolt Leader and Wiring Harness for a 2007 Chevy Impala
  • All of the hitches sold on our website come with the necessary hardware to install the hitch on its respective vehicle, but do not include the tools. If you should decide you need to purchase a bolt leader for the installation of the Draw-Tite Class II Trailer Hitch Receiver, item # 36407, you will need the 1/2 inch Bolt Leader, part # 80101-1. The T-One Wiring Harness for your 2007 Chevy Impala is sold separately from the hitch, and it is the T-One Vehicle Wiring Harness, item # 118417....

  • Malfunction Turn Signal Light on Sunline Travel Trailer
  • The first step would be to check the wiring from the malfunctioning light all the way up to the connector. Make sure all the connections are reasonably clean and secure, and check for frayed wires. If everything looks good from there, I would begin to look at the tow vehicle wiring. Check to make sure your connections are clean and secure. We have a few handy devices that could help you check all this. You could use a circuit tester like part # 3808 to check to see what connections are...

  • Will the Draw-Tite Class II Trailer Hitch # 36407 Fit on a 2009 Impala LTZ with Dual Exhaust
  • Yes, the Draw-Tite Class II Trailer Hitch, item # 36407, is designed to work with the dual exhaust models. There is not a lot more time, or trouble, required for installation on dual exhaust models. The only difference is that you have to lower the drivers side exhaust as well as the passengers side. We have an installation video on a 2007 model that has the dual exhaust for you to review, see link. I have also included a link to the installation instructions for you to review. Some...

  • Recommended Hitch And Combination Transmission/Oil Cooler For 2009 Chevrolet Impala
  • For your 2008 Chevrolet Impala, I recommend the Draw-Tite Trailer Hitch, part # 36407. This is a Class ll hitch and has a 1-1/4 inch receiver opening. The drawbar I recommend for this hitch is part # 36061. This features a 3-1/8 inch rise, and uses a hitch ball with a 3/4 inch diameter shank. This includes the pin and clip. For a 1-7/8 inch hitch ball I recommend part # 19257, and for a 2 inch hitch ball I recommend part # 19258. Transmission and oil coolers are not vehicle...

  • Parts Needed to Install a P2 Trailer Brake Controller on a 2013 Chevy Impala
  • The 2013 Chevy Impala and most other cars do not have tow package wiring so there is no wire bundle or plug in port under the dash to plug in a brake controller. It will be a hardwire installation. The best place to run the wires from the controller to the battery would be at or near an existing harness that goes through the firewall. Ideally, you would run the wire without making any additional holes. But sometimes, there is no space at all to shove a wire through at an existing exit/entry...

  • Will the Trunk Open on a 2007 Chevrolet Impala With a Trunk Mounted Bike Carrier
  • You would not want to open the trunk while a trunk mounted bike rack is installed on your 2007 Chevrolet Impala because it could cause damage to the vehicle. If you would like to have access to your trunk without having to remove the bike rack every time, then I would recommend adding a hitch and hitch mounted bike rack. For your vehicle, I would recommend the Hidden Hitch Class II Hitch, # 90137. There will be no contact between your vehicle and a hitch mounted bike rack and you will...

  • Can a 2008 Chevrolet Impala LTZ Tow a Snowmobile
  • Your owners manual is the best resource to use when determining towing capacities of your vehicle, see section 4. I found a copy of the owners manual for a 2008 Chevrolet Impala and Chevy states that an Impala can tow a trailer, but the gross trailer weight must not exceed 1,000 lbs. Keep in mind, Chevy gives the Impala a maximum towing capacity of 1,000 lbs assuming the driver is the only additional weight in the vehicle. If there will be additional passengers and cargo in the vehicle,...

Next, install the carriage bolts and blocks through access holes in the vehicle frame on both sides. Then, install carriage bolts and blocks through access holes in the vehicle cross member.

They are the same hitch, the only difference is the Hidden Hitch part includes the ball mount # 36061. Both hitches are a Class II hitch with a 3,500 lbs. towing capacity and a 300 lb. tongue weight capacity. I am sending a link to the installation instructions on the hitch.
