Tekonsha Custom Fit Vehicle Wiring - 118301

  • 4 Flat
  • Custom Fit
  • Trailer Hitch Wiring
  • Converter
  • Tekonsha

Quickly and easily install a 4-way trailer connector on your vehicle with this custom wiring harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Circuit-protected converter guards against shorts.


Features:

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights
    • Compatible with 5-pole, 6-pole and 7-pole adapters (sold separately)
  • Connects quickly and easily - no cutting or splicing of wires
    • Locate connection points beneath the truck bed, on the driver's side
    • Plug in T-connector
  • Includes circuit-protected tail light converter to ensure that your vehicle's wiring matches that of your trailer
    • Provides protection against electrical shorts and overloads
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 2.1 amps per circuit
    • Tail lights: 5 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located beneath the truck bed, near the driver's-side frame rail.


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


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.

Incredibly easy to install. Drilled one hole to mount the converter and another for the grounding screw (self-tapping screws). Routed the wiring, and it's fantastic to allow me to tow my trailer.

Wow! I ordered my hitch and wiring harness on 3/16/16 at 9:39 AM and it was delivered via free shipping on 3/17/16 in the early afternoon. I have it installed and ready to use and it is only 4:30. Great service, great product, clear instruction and acceptable pricing.
Thank You!

Trailer hitch fit great on truck. Directions that came with it worked well. Took about 45 minutes to install the hitch and wire harness by myself on my 2012 Chevy Colorado.

Awesome trailer hitch but took more than an hour. But still awesome!

Great products, good video instructions, quick shipping, and a good price.

Tekonsha towing "Plug in T" wiring harness for a 2007 Chevy Colorado....The product was excellent, just as described. It literally did, in fact, install in about 5-10 minutes. Your website was extremely helpful regarding the product. The installment videos are what sold me. The only reason I didn't give a 5 star rating was the 7 day delivery. Other products I buy online deliver in 3-4 days. Product Great, Delivery... could be faster.

I wasted two days and was at my wits end trying to figure why the Dealer installed wire harness did not work, after spending Two minutes on your web site and watched your videos problem was solved, the dealer installed the wrong harness, I ordered this harness and you shipped it the next morning.
Excellent service, even greater videos, and top rated web site and the exact products.
I rate you guys 10 +++++

Quick and easy to install and worked great on my 2005 Colorado. Thanks.



by:
2006 Chevrolet Colorado

It was great! After a year of frequent use taking on a salt water the wiring harness works great!! As a former Electronics Technician my only recommendation would be to highlight the importance of a good ground connection. Because many trailers are typically constructed of solid metal this is not a problem. But where modifications are made using wood and other non-ferrous metals a bad ground will interrupt the system.



by:
2005 Chevrolet Colorado

Everything worked perfectly. Would definitely order from you guys again. Very fast shipping as well.



by:
2009 Chevrolet Colorado

Product came on time and in good condition. Installation is easy for DIY and I had no problem. I own a 2009 Chevy colorado and the unit works perfectly. I rented a trailer from home Depot and the tail lights worked as designed. I got this unit because I didn't want to do any wire splicing or soldering. I only used a drill for a screw to attach the unit to the truck frame with also some RTV and a few zip ties. I would buy again if need be.



by:
2005 GMC Canyon

The product was exactly as pictured. It installed very easily in approximately five minutes. More time passed waiting for my cordless drill to charge than the actual installation. The self tapping screw for the ground wire was great. The installation literally was unhooking the existing wire connectors, putting the T connector between them, and then running the wire towards the ball hitch.
I have yet to hook anything to the connector at this time to enure all is functioning correctly though will tow a trailer in another week to test it.



by:

I'm not certain how easy pie is (I'm to busy making my truck cooler, but this must be as easy or easier.

You'll lay down behind your truck, and you'll luck at the back of the rear bumper. There you will see a big flat pin connector and you'll unclip it and then using strategic reasoning skills you'll plug the correct end of the new fancy deal from etrailer into those two spots you just created.

Then you'll just need to get a self tapping screw and mount the ground to something metal, preferably not the color of the truck (that's the bed, don't screw it into that).

Then you're freaking done and you can tow stuff legally!



by:

works great for my 06 colorado! simple plug and play. FYI does not have a fuse. if you have a trailer short it will just fry the unit. make sure your pluging into good trailers. i fried one because the running lights had a direct short to ground.

I recently purchased a Hidden hitch and wiring harness for my 2011 Chevy Colorado. With the install videos online, installation couldn't have been more straight forward. Shipping was fast and pricing was very good! I highly recommend etrailer!



by:

The t-connector was delivered promptly, installed easily, and worked well. I must also mention that etrailer customer support is fantastic! Ashley particularly helped work through a few difficulties with my truck.



by:

Great product! It is working as it should, no complaints.



by:
2005 GMC Canyon

I am quite pleased with my recent purchase. The hitch fits perfectly and the T one electrical hook up was sooo easy that I let my 3 year old great nephew make the connection. He's not afraid to try new things just like his Aunt. :)

To install the hitch I made a crude ramp (inclined plane) from 2x4's and bricks. Kind of like when the Egyptians built the Pyramids.

I highly recommend etrailer to anyone looking for anything from your company. The prices were the lowest of all the sites I checked. Delivery was free and your company arranged for a delivery a full two days earlier than originally quoted.



by:
2010 Chevrolet Colorado

Product that I ordered was not in stock and they informed me of an item equal to what I order and gave me the option to cancel first order and order the in stock item. This was all done within the first couple days of placing original order.
I have to say that is EXCELLENT CUSTOMER SERVICE and I am very satisfied with the replacement item that was as they described. I ordered a quick connect trailer harness for my Chevy Colorado and the instruction said it would take roughly 1/2 hour to install, (FALSE after watching etrailer install video it only took 10 minutes including reading the instructions, Another fine example of good customer service)
Very pleased and will recommend etrailer to anyone needing their products.

  • Trailer Wiring Harness for a 2015 Chevy Colorado
    We do have a trailer wiring harness that will fit your 2015 Chevy Colorado. You can use # HM11141164 that plugs in line with the vehicle tail light wiring. I have linked a video review for you. Harness # 118301 does not fit the 2015 models.

    I recommend going with the Draw-Tite Max-Frame Trailer Hitch Receiver # 75607 hands down for your 2012 Chevy Colorado. I like this option over the Curt # 13252 because it has a hidden crosstube which not only looks better, but it also means you'll have better ground clearance. Attached is an installation video as well as a photo showing what it will look like once installed. Typically when a trailer hitch is installed on a pickup it will be used for towing.

    To install the Redarc Tow Pro Elite part # RED44FR in your 2008 Chevy Colorado that does not have any trailer wiring you'd first need to start with the 4-way kit part # 118301 and then convert it to a 7-way/4-way with the part # ETBC7 which comes with everything needed to install the brake controller and provide you with both a 4-way and a 7-way.

However, if your Colorado did not come with a factory 7-way then you will need to run the brake controller wires yourself.

    Yes, the Adapter 4 Pole to 7 Pole Vehicle End Trailer Connector # 30717 will work on your 2012 Chevrolet Colorado. This is a universal part so it will work on any vehicle. You will need to have a 4-way connector on your Colorado as well to plug into this adapter, so if you don't have one the correct part for that is the T-One Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # 118301.

    I can definitely get some parts recommended to set your 2008 Chevy Colorado up with a brake controller. First, you will need to start with a 4 Flat if you do not already have one. If you do not, the Tekonsha # 118301 will be a plug and play harness that will take no time to get installed. To get up to the 7 Way, it will need to piggyback off of the 4 Flat, so it is definitely needed. Next will be the Universal Installation Kit for Trailer Brake Controllers # ETBC7. This will include the...

  • Trailer Wiring Harness Recommendation for a 2007 Chevy Colorado
    Actually to install a 4-way in your 2007 Chevy Colorado all you would need is the part # 118301 that plugs right in to factory wiring on your truck. There would be no need to hardwire anything at all. Also, since your truck has separate turn signals from brake lights you couldn't just hardwire a 4-way to the wiring anyway so the # 118301 would be your best option. I attached an install video for you to check out as well.

Just like in the video I attached. If the voltage checks out there but the trailer lights still don't function right then the problem is on the trailer wiring.
