Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located inside your trunk, behind the tail lights on both the driver's side and passenger's side. You will need to remove some interior trim or carpeting to access the harness.


Once installation is complete, the 4-way flat connector will be stowed within your trunk.


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.


Circuit-Protected Tail Light Converter

A tail light converter is built into this T-One connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your vehicle's three-wire system need to be combined so they are compatible with the wiring system of your trailer. The tail light converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your vehicle operate.


This converter safeguards itself and your vehicle against possible electrical shorts and overloads with integrated short circuit protection. Just install the connector as indicated and rest assured that the wiring system of your vehicle will remain feedback-free.

Video Transcript for Tekonsha Custom Fit Vehicle Wiring - Trailer Hitch Wiring - 118485 Review

Today we are going to be looking at part 118485. This is a T1 vehicle wiring harness with your four pull flat trailer connector. This product is going to fit certain years and models of the Chevrolet Aveo, Pontiac G3 and Pontiac Wave. It's going to provide your four way flat trailer connector at the back of the vehicle to power your trailer's signal lights. This is compatible with five pull, six pull and seven pull adapters. Adapters are sold separately. It does come with a dust cap for a four way flat connector.

That way you can protect those connection points when your plug is not being used. The black box right here, this is going to be the included circuit protected tail light converter. This is going to ensure that your vehicle's wiring matches that of your trailers. It's going to provide protection against electrical shorts and overloads. The main benefit of a system like this is that it is designed to connect quickly and easily as well as provide the four way flat connector at the back of the vehicle. Pretty simple installation.

All you need to do is locate the connection points in the trunk, and then plug in your connectors. You're going to see that you have two sets. The set with the green and red wire, that's going to go to the passenger's side of the vehicle. Yellow and brown wire, that's going to go to the driver's side of the vehicle. Plug those in.

Custom fit plugs, so they're going to match up perfectly with the plugs on the vehicle. Then you're going to need to make a ground connection. That's going to be the white wire with the ring terminal attached to it. You can make that ground to a nice clean metal surface using the included self tapping screw that is provided with the kit. Then you can secure the converter box. It's going to come with some double sided adhesive tape on it.

You stick that to a nice clean out of the way location. Once you have everything connected and secured, you can go ahead and use the included zip ties to secure any excess wiring that you may have. Keep it up and out of the way. Once your installation is complete, the four way connectors are going to be stowed within the trunk of the vehicle. When it comes to the maximum amperage for the stop and turn lights, we're looking at 2.1 amps per circuit. For the tail lights, we're looking at 7.5 amps per circuit. It's also recommended that you use a small amount of dielectric grease on all your electrical connections, like the plugs on the vehicle and the four pole connector itself. That's going to prevent corrosion. If you need some of that, it is sold separately, but you can find it right here at eTrailer.com. That's going to do it for today's look at part number 118485.

The wiring harness was money well spent. It snapped rite into the factory harness. No cutting, splicing or scotch locks to worry about failing at the worst time. Everything was neet and tidy. It took about 15 minutes to install.

  • Troubleshooting Turn Signals and Brake Lights Not Working With Curt Wiring Harness on 2009 Aveo5
    With the installation of a new Curt wiring harness I doubt there are any issues with the converter, and it should have more than enough power unless you have an unusual number of lights on your trailer. I would check out the ground connection, which is likely the issue. I'm guessing you used the same ground connection when you installed the new wiring harness. Make sure it is secure on a clean, bare-metal surface. It might be best to go ahead and relocate the ground just to be sure. If...

  • Hitch Possibilities for a 2004 Chevy Aveo 5 Door Hatchback
    I have two options for a trailer hitch for your 2004 Chevy Aveo 5 door hatchback. Unfortunately, both of the options require two holes to be drilled in the bumper beam. I have attached a short installation video for an Aveo 5. It is a different year, but the installation is the same so you can see if this is something you would be able to accomplish. If you are wanting the hitch for a hitch mounted accessory such as a bike rack, then I recommend the Draw-Tite # 24741. If you are going...

  • Is it Legal to Install Trailer Hitch on 2009 Chevy Aveo5
    For your 2009 Chevy Aveo5 we have the Curt hitch part # C11306 as a confirmed fit. It is perfectly legal to install this hitch on your vehicle. You would want to check your owners manuals for any restrictions on towing and be sure to follow them. For trailer wiring you'd then want the part # 118485. For a ball mount part # C45521 and for a hitch ball # A-80.
