Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located inside your rear cargo area, behind the tail lights on both the driver's side and passenger's side. You will have to remove the rear threshold, cargo cover, and some interior paneling to access this harness. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


Once installation is complete, the 4-way connector will be stowed in your rear cargo area.


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.


ModuLite Powered Tail Light Converter

A ModuLite power module is built into this T-One connector. Because your vehicle runs on a multiplex wiring system, the wiring needs to be converted to be compatible with the wiring system of your trailer. This power module functions as a tail light converter to combine 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.


With a ModuLite, your trailer's lights will be powered without overloading your vehicle's electrical system. Because the module draws power directly from your car's battery and bypasses the electrical routes that are used by a basic wiring harness, there is virtually no draw on your tail light circuits.

Everything I haved purchased through etrailer has been 5 stars. Packaging, quality,value,shipping and even instructions/ videos.



by:

Came quickly. Great quality. Excellent service with follow up email making sure everything was up to standard with my order. I’d give this place 10 stars if it was an option. Thank you for going above the standard

It's easy to install for the most part hardest thing was running the power wire



by:

Installation was straightforward. The connectors were very easy to install as it was a plug-and-play system. The directions were mainly easy to follow. However, the installation was easy enough that I did not need them. It works great for towing my motorcycle trailer and is affordable compared to UHAUL installations.

I have used e-trailer hitches and parts in the past. It has been many years ago. But I knew I could trust these parts and their durability and quality and appearance. After placing my order I received the items within 2 days. You cannot beat such wonderful shipping service. The directions that came with the hitch and the wiring harness for my Chevy spark were so detailed and easy even for an old 74-year-old dummy like me to follow. Lol. Also available was a couple of videos online with YouTube on installing the hitch on a Chevy spark. Such wonderful service and quality parts. I installed the hitch and wiring harness today. Although it did take me a good bit longer than what the perspective time was in the directions. Lol. That is just me. A great company to work with. Thank you so much e-trailer. I am a senior on a very tight fixed income and I have survived lung cancer and another cancer also. I only have one long left and cannot afford a larger vehicle and a travel trailer. So I have put the trailer hitch on my small Chevy spark and I am buying a minimate compact camper to pull with it. I have decided to travel some across this country while I am still able. Being that money is tight I can camp in this out west on BLM land for free. Now I can hardly wait to pick up my tiny little motorcycle camper. E-trailer you made things very easy for me and made this old man very happy. Thank you again.

Easy installation and arrived before estimated shipping date. The only problem I had was getting the trailer running lights to function. Brake and turn signal lights worked fine but had to run a separate wire from car running light to make trailer running lights function.

Not enough wire! Even for a Chevy Spark. Unusual for etrailer, this kit came without all the parts needed. There's enough 4 pin connector harness to reach to the back of the driver's seat (not to mention through the fire wall, engine compartment and the length of the tow bar). I had to buy extra wire and another 4 pin connector.

Also, the wire color choices in the instructions (connectors to the tail lights) didn't quite match the connectors themselves. Gave me pause for about 10 min. during install.



by:

Delivery was slow, pandemics fault I'm sure. Product is great, went in as it should, it was worth the wait.



by:

It was easy to install and was a good after market product for my car.

See what our Experts say about this Tekonsha Custom Fit Vehicle Wiring

  • Can a 2019 Chevrolet Spark Carry 2 E-Bikes Using a Hitch Mounted Bike Rack?
    Yes, you can install a Curt Trailer Hitch Receiver # C11433 on your 2019 Chevrolet Spark. This receiver is capable of supporting up to 200lbs of tongue weight. With each of the Lectric 3.0 e-bikes weighing roughly 60lbs without the battery you will need a carrier like the Thule EasyFold XT # TH903202 which is capable of supporting 2 bikes up to 65lbs each and working with your class I receiver. I do recommend installing the T-One Vehicle Wiring Harness # 118694 when you install the receiver....

  • Compatibility of Hopkins Wiring Harness on 2016 Chevy Spark
    The Hopkins Plug-In Simple Vehicle Wiring Harness with 4-Pole Connector # HM11141120 is a confirmed fit for 2013-2020 Chevy Spark models according to the manufacturer. There is not any modification required according to the manufacturer. We have not installed that particular harness on a Spark or we would have a video of the installation to assist. If you can give me a little more information on how it isn't fitting I may be able to assist you in troubleshooting. It is odd that...

  • Does Tekonsha Wiring Harness Fit 2022 Chevy Spark ACTIV

  • Wiring Needed To Flat Tow 2017 Chevy Spark
    The towing wiring harness 4-Pole Flat part # 118694 for the 2017 Chevy Spark is different than the wiring needed for the tow bar to flat tow the vehicle. There is not a plug and play option for tow bar wiring on the Chevy Spark. I recommend to use the Roadmaster Tail Light Wiring Kit with Bulbs part # RM-155 which will give you a 6-way plug on the front of the vehicle and an additional bulb in the tail lights so you are not splicing in the vehicle's wiring. You will be bypassing the vehicle's...

  • Recommended Trailer Hitch Receiver and Bike Rack For Carrying 2 E-Bikes With a 2018 Chevrolet Spark
    I recommend the Curt Trailer Hitch Receiver # C11433 for your 2018 Chevrolet Spark. With this Curt Receiver you will need to use their Stabilizing Straps # 18050 when you are using any hitch mounted accessory like a bike rack that you are looking to install. The Tekonsha T-One Vehicle Wiring Harness # 118694 will provide you with a 4-way connector on your Spark. This will allow for you to use Auxiliary Lights # C53201 on your bike rack since the bikes will impair the view of your tail...

  • How Many Amps Does Tekonsha Trailer Wiring 118694 Draw
    Hey Anthony, the Tekonsha trailer wiring harness # 118694 will draw up to 4.2 amps for the stop/turn circuit and 7.5 amps for the running light circuit. Now with that said it still is required that you run the power wire up to the vehicle battery as annoying as that seems. The reason for this is that in the event the trailer wiring has a short it won't take out any vehicle wiring circuits as this is essentially a form of circuit protection.

  • Trailer Wiring that Fits 2017 Chevy Bolt EV
    We have a universal style of trailer wiring harness that is a fit for your 2017 Chevy Bolt EV that doesn't require any splicing. What you would want is the # 119250KIT which instead of requiring hardwiring uses sensors that grab the wires without piercing them. We do not have any custom fit options for your vehicle.
