Tekonsha Custom Fit Vehicle Wiring - 118597

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

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. 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

    • 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: 4.2 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 inside your rear cargo area, behind the tail lights on both the driver's side and passenger's side. You will need to remove the interior access panels to reach the harness. Once you've plugged in the T-connector, run the hot lead with the attached fuse holder to the car battery in your trunk. Connect the fuse holder to the positive terminal on your battery and insert the provided fuse.


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

I installed this trailer light wiring kit on my 2013 Nissan NV200. Everything fit perfectly, and after running a power wire up to the battery, no small challenge in this van, everything worked flawlessly. I would easily give this product an "Excellent" rating. A good quality electrician's "fish" wire helps a lot.....

I tow regularly and everything works perfectly . I am pleased with the quality and durability of all components.



by:

Excellent harness! Simple plug-in connection, well-designed installation and clear instructions. I've had this wiring in my van for a year, and have had no issues whatsoever, so if you want to make your trailer wiring job easy and durable, purchase this- you will be pleased!

This the the 4th hitch I have ordered for a vehicle from etrailer. Service is always fast. Parts are accurate. Installation has never been difficult.

If I ever need another hitch, I'll be back.

All works fine. When I need trailer parts for my new vehicles, RV, or trailer, I always shop etrailer.

I had my mechanic install the hitch and lighting system because I didn't have a lift and, well, quite frankly, it was too damn hot outside for this chubby [me] to be rolling around in the driveway. Mechanic said the install was a pretty painless process, all the bolt holes lined up, etc.. Seems to be a very high quality product, shipping was a breeze, good communication with seller. Highly recommended.

Just finished my tow harness install on my NV200
gotta say etrailer has made it very easy, it took me about 45 min but more than anything it was very simple thank you guys very much I am very satisfied with the finish product, also I ordered it online, very easy to order.

Wiring harness fit my 2014 Nissan NV 200 exactly. No cutting of wires everything plugged into my existing harness!



by:
2015 Chevrolet City Express

The connector hook up was a snap. Only issue us with snaking the harness with connectors attached across the top/back. Took a little working underneath to route the power wire up to the battery, but it all worked out well. Knowing what I do now I would still buy thus product



by:
2015 Nissan NV200

Look great on NV200 nissan, it was a little hard fishing bolt and locking washer threw fram to attach hitch, they need to take slow fishing threw. And the t-connected was very easy to hook and running black from battery to t-connected was easy also, thanks for all the material ship with every.



by:

After receiving the new hitch, I went right to work installing it. The NV 200 is very low to the ground, so a lift of some sort would've been a plus. After fishing the bolts through the frame, the remaining installation went very well!
I had it installed in less than 2 hrs. The fit was perfect!



by:

I ordered it online after looking at it, it arrived in 2 days and plugged in exactly like the directions said. The only problem I had was routing I could not go over the top there were too many obstacles to pull the connectors through.I had to go underneath the Matt in the back which was no problem. It was plug and Play real simple



by:

Hitch and wiring worked perfect. Was a bit tricky fishing the bolts thru the frame tubes, you just have to take your time.



by:

Went in easy enough. Would have liked shrink-on fittings and a picture to show how/where to mount the module. Thought this would provide instructions to run wire outside permanently. This unit stays in van and you pull out when you need it. Should work well for my application.



by:

Was able to install this myself - easy to follow instrucations
Works great with my 5 X 8 utility trailer I use for hauling my zero turn around or for picking up lumber for my shop - great.



by:
2019 Nissan NV200

product works perfect- most time consuming part is getting wiring through truck to battery-rest of it plugs and plays



by:

What a great company they called and informed me that the receiver hitch I had ordered was on backorder however they had another that was in stock and saved me some money. Way to look out for the customer.......



by:
2017 Chevrolet City Express

More difficult to install than instructions lay out.



by:

Everything ordered was delivered as promoted and very fast delivery. I will purchase again from etrailer and recommend my friends.

  • Where to Bring Out 4-Way on 2016 Nissan NV200 When Connecting to Trailer
    The 4-way connector on the T-One Vehicle Wiring Harness # 118597 will store inside the rear cargo area of your 2016 Nissan NV200 when you aren't using it. This means that any time you want to connect a trailer all you have to do is take it out of the rear cargo area to connect it; you can close the rear doors on your NV200 and the connector will still work fine

  • Modifications Required to Install Class III Trailer Hitch Receiver on 2014 Nissan NV200 Van
    We do have confirmed 2-inch hitch fits for your 2014 Nissan NV200 van and all can be seen on the link at right. All share a Class III rating, 3500-lb maximum trailer weight capacity and all install without drilling using included hardware. Installation of any of these hitches will require temporary lowering of the exhaust and spare tire (for better access to the hitch mounting points). Also all will require some degree of trimming of the underbody fascia panels. Since all three hitches...

  • Is A Separate Wire For Power Required If Trailer Has LED Lights
    We offer a custom fit wiring harness designed for your 2013 Nissan NV200. That is part # 118597. LED lights on your trailer will not have an effect on the installation of this harness on your vehicle. The installation does require you to run a wire to the battery for the Modulite tail light converter. I have attached a product review video for this harness.

  • Trailer Hitch Recommendation for 2018 Chevy City Express
    For your 2018 Chevy City Express the Draw Tite part # 75898 is the best option as it is a confirmed fit, is a 2 inch hitch size, great towing capacities and unlike the Curt equivalent it does not require a stabilizer strap when carrying a bike rack. For trailer wiring you'd then want the part # 118597. If you wanted to do some towing you might be interested in etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and one with a 2-3/4 inch...

  • Does Trailer Hitch From 2006 Dodge Dakota Fit 2017 Nissan NV200
    Trailer hitches are vehicle-specific fits so a hitch from a 2006 Dodge Dakota would not fit a 2017 Nissan NV200 van. For a '17 NV200 I recommend the Draw-Tite # 75898, which is a Class III hitch with a 2" receiver that bolts on; it will not require any drilling into your van's frame to install. For wiring which will give you a 4-way connector and allow you to power your trailer's lights you need Wiring Harness # 118597. I also recommend checking out Ball Mount Kit # 989900, which is...

  • Trailer Hitch Recommendation for 2017 Nissan NV200
    For your 2017 Nissan NV200 I would recommend the Draw Tite hitch part # 75898 which is a confirmed fit and will give you a 2 inch opening and plenty of towing capacity at 3,500 lb trailer capacity and 525 lb tongue weight capacity. I like this one over the Curt because it's virtually identical in every way yet costs a bit less. For trailer wiring the best option is the Tekonsha kit part # 118597 as the converter boxes made by Tekonsha are the most reliable. If you wanted to do some...

  • 4-Pole Trailer Wiring Harness Fit for 2015 Nissan NV200
    My contact at TowReady, maker of the wiring harness # 118597 that you referenced, advised that this 4-pole kit should work on your 2015 Nissan NV200 although the harness hasn't been formally tested on the 2015 model year vehicle. Since it does fit the 2014, which is the same generation, the odds are that it will fit and work just fine. You can easily check the fit of the harness in advance of purchasing it by taking a look at the harness' connectors shown in the linked photo. If the connectors...

  • Trailer Wiring Harness that Fits 2018 Nissan NV200
    The only solution we have for installing a trailer wiring 4-way on your 2018 Nissan NV200 is going to be with the part # 118597 which installs by plugging inline with the vehicle taillight connectors. Or you could hardwire in a kit like the # C59236 if you wanted to wire directly to the wires instead of mess with connectors.

  • Trailer Wiring Harness for a 2013 Nissan NV1500 Van
    The trailer wiring harness # 118597 will only fit the 2013 Nissan NV200. It will not fit the 2013 Nissan NV1500. For the NV1500 Hopkins has harness # 46365 as a fit for the NV van but it is a hardwire installation, not a T-connector style. You will need to use a circuit tester such as # PTW2992 if you need one and test the tail light wires of the vehicle. On the harness, white is ground, red with the butt connector on it gets attached to the positive battery terminal via the in line fuse...
