Tekonsha Custom Fit Vehicle Wiring - 118775

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

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-One connector plugs directly into existing wiring - no cutting, splicing or tapping required. Powered ModuLite reduces strain on wiring system.

  • 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
    • Locate connection points in rear cargo area
    • Plug in T-connector
    • Run hot lead to car battery
  • Includes ModuLite to ensure that your vehicle's wiring matches that of your trailer
    • Powered module connects directly to battery to avoid overloading vehicle's electrical system
  • Constructed of 16-gauge bonded wire
  • Comes with dust cap for 4-way flat connector


Specs:

  • Maximum amperage:
    • Stop/turn lights: 5 amps per circuit
    • Tail lights: 7.5 amps per circuit
  • 1-Year limited warranty


Installation

This custom-fit T-One connector plugs into your vehicle's wiring harness, which is located behind an interior trim panel in your rear cargo area, on the driver's side. Remove the plastic threshold cover, side panels, and cargo trays to access the wiring. 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 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 multiplex system need to be combined so they are 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.

etrailer is the first company that I have ordered from and they had my 3 products shipped out so quick. My products arrived on time and were in perfect condition.I would definitely recommend etrailer for buying parts they are AWESOME!!!

Product is good, but instructions could've been better. I had to use instructions provided by CURT (similar product).


Comments
I wanted to reach out to you in regards to your review on the wiring harness. You mentioned that the instructions could have been clearer and I wanted to ask if you could explain in more detail what you meant.
-- Etrailer Expert Jenny N - 11/24/2021
Instructions provide for the same wiring harness from CURT Item # C49KR that you have on your website have more detailed instructions on how to remove a particular panel that is required to install this harness, so I dont have to guess or go to vehicle service manual. Other than that product is great, already installed and checked and it works.

The product was packaged well, organized, and simple to install (the Videos are a great help for someone with no knowledge). I'm happy with the product so far, after installation I did a quick test and everything worked as it should. This light plug will be used primarily for connecting lights on my small utility trailer and boat trailer. I'm looking forward to years of hassle free towing with no lighting issues. I would recommend this product and installing it yourself.

I got it quickly, and it worked fine. I can't really ask for any more! I bought it online at around 2:00 am, and by 7:30 am I'd already gotten an email saying my order had been processed.

Thank you etrailer group. You do a good job, and I'll remember you next time I need anything.

  • Will 2006 Nissan Murano Tail Lights Still Work w/Trailer Wiring Harness Installed and Not Towing
    All of the tail lights on your 2006 Nissan Murano will still work perfectly fine with wiring harness # 118775 installed even when not towing a trailer. You will not have to disconnect it every time and then reconnect it when you want to tow again.

  • Trailer Wiring Harness for 2006 Nissan Murano with LED Tail Lights
    I checked with Curt and they did confirm that on a 2006 or 2007 Nissan Murano with LED lights you'll likely have dim trailer lights using their 56305 harness. There's a plan in place to solve this but it isn't available yet. Instead I recommend going with the Tekonsha harness, part # 118775. It installs in the same fashion as the Curt but doesn't cause the dimming issue you're getting. Tekonsha converters are pretty common for being more reliable than Curt's from our experience.

  • Where Does 4-Way of 2007 Nissan Murano Store
    Having the 4-way run out of the back hatch is actually the preferred method although it seems like it wouldn't be. Having the 4-way stored inside the cab of the vehicle keeps it protected from rain and moisture to prevent corrosion and keeps it protected from damage to the wiring or connector by rocks or debris that might be on the highway. We see trailer wiring issues here daily and most of them are caused by corrosion in the trailer wiring pins due to the connector be stored outside...

  • Vehicle Wiring Harness with Powered Converter for a 2007 Nissan Murano
    The Modulite wiring harness # 119147 could be used on your 2007 Nissan Murano, but I recommend the T-Connector wiring harness, part # 118775. There are 3 reasons for my recommendation, it installs much easier, comes with all the necessary hardware for installation and will not require you to splice into the vehicle wiring. This custom vehicle wiring works the same as the Modulite wiring harness by drawing power directly from the vehicle battery instead of through the vehicle wiring system....

  • Is a Square or Round Tube Trailer Hitch Stronger for a 2006 Nissan Murano
    No matter how a hitch is constructed, round or square, they are all built for and tested for a certain capacity based on many factors. Two different hitches, one with a round tube and one with a square tube, that have the same capacity will be equally as strong. They have to be to reach the rating they are given. With that said I am of the opinion that square is stronger in the long run. Any of the hitches we carry for the 2006 Nissan Murano are rated for 3,500 pounds gross trailer weight...

  • How To Mount And Wire A Brake Controller To A Nissan Murano
    The Tekonsha Vehicle Wiring Harness, part # 118775, is a wiring harness for a 2006 to 2007 Nissan Murano. If you do not have a 4-Pole flat connector on your Murano this harness will give you a 4-Pole flat trailer connector on the back of your Murano. If you already have a 4-Pole on your vehicle you will not need this part. The Curt wiring harness will plug into existing sockets on the vehicles wiring harness, located under the trunk liner in the rear cargo area. You will also need to run...

  • Can a 1952 Terry Trailer Be Towed By a 2006 Nissan Murano and What Parts Will Be Needed
    To get the weight of your 1952 Terry trailer I would try to see if it has any type of identification plate or sticker on the trailer itself or the trailer axle that might indicate the weight of the trailer. The other choice if you cannot find a plate is to get it weighed on a local commercial scale at a truck stop, quarry or material supply center. I am including a link to a FAQ page that will talk about determining the weight of your trailer. After you find out the weight of your empty...

  • Best Trailer Towing Setup for a 2006 Nissan Murano
    The wiring you need is the Tekonsha T-One # 118775 wiring kit as it is the only one available for your 2006 Nissan Murano. For a trailer hitch I recommend going with the Curt Trailer Hitch Receiver # 13571 which is a Class III hitch with a 2" receiver. It has a Gross Towing Weight (GTW) rating of 3,500 lbs and a max Tongue Weight (TW) rating of 350 lbs but you will want to check the weight capacity rating of your Murano in your owner's manual to ensure that you do not exceed the lower...

  • Tailer Hitch and Wiring for a 2007 Nissan Murano to Tow a Rental Trailer
    Rental places like Uhaul require that your 2007 Nissan Murano has a trailer hitch rated for the weight of the trailer, a trailer wiring harness to activate the trailer lights, and accessories such as a ball mount and ball. But if the trailer has surge brakes or electric brakes you will need some additional equipment such as a brake controller and 5- or 7-Way trailer connector. Starting with a trailer hitch you can use Curt hitch # 13571. It is rated for 350 pounds tongue weight and 3,500...

  • Do you have a Photo of The Draw-Tite Hitch for the 2006 Nissan Murano
    Yes, the photo on our web page is of the actual hitch. If you mouse over the image links below the title you will see more actual pictures of the hitch and the display image shows the hitch from the underside of the vehicle. The Photo of the Draw-Tite Class III Trailer Hitch, item # 75148, is also the actual photo but we have not had the opportunity to photograph it on the vehicle. We also have a video installation of the Curt Class III Trailer Hitch on a 2007 model Nissan Murano (see link)....

  • Trailer Wiring and Brake Controller Recommendation for 2007 Nissan Murano
    You will need to start with a 4-way (if you do not have one) installed on your 2007 Nissan Murano. For that you would want the # 118775 which is a confirmed fit and would work well. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake...

  • Exhaust Must be Lowered for Installation of the Curt # 13571 Trailer Hitch on a 2006 Nissan Murano S
    I spoke with the technical department at Curt Manufacturing and found that installation of the Curt Class III Trailer Hitch, item # 13571, on the 2006 Nissan Murano S model requires lowering the exhaust on both sides of the vehicle, for installation of the hitch. You do not need to bend or manipulate the exhaust in any other way and when the install is complete you will return the exhaust to its factory position. We have a video review of a hitch install on a 2006 Murano for you to check...

  • Bike Rack Recommendation for a 2006 Nissan Murano LS
    We have trunk mounted bike rack options that are listed to fit your 2006 Nissan Murano, but Yakima does not list any trunk mounted bike racks that will fit your vehicle. The Thule Gateway Pro 2 Bike Rack, # TH88VR, is similar to the Yakima HangOut 2 Bike Rack, # Y02637 that you referenced and Thule has confirmed that this bike rack will fit your vehicle. After doing a little research on your vehicle, I would recommend installing a trailer hitch and using a hitch mounted bike rack. Most...
