2017 Toyota Prius v - Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector

  • Trailer Hitch Wiring
  • 4 Flat
  • Powered Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your Toyota Prius v with this custom harness. T-connector plugs directly into existing wiring. Powered converter reduces strain on wiring system and is made using SMT to ensure superior performance.


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 in rear cargo area
    • Plug in T-connector
    • Run hot lead up to car battery
  • Includes a tail light converter 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 using surface-mount technology (SMT) for consistent, reliable performance
    • Maximizes trailer light yield and intensity while producing minimal heat
    • Ensures superior operation in rough road conditions
  • Comes with dust cap for 4-way flat connector
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located behind the driver's-side and passenger's-side interior trim panels in your rear cargo area. Once you've plugged in the T-connector, run the hot lead up to your car battery. Connect the lead to the positive terminal on your battery and insert the included 10-amp fuse into the in-line fuse holder.


Once installation is complete, the 4-way connector will be stowed in an out-of-the-way location within your 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.


Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


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 the trailer. This 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.


Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.


Curt SMT Circuit Boards

Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.


Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

We got this hitch and wiring harness for our '12 Toyota Prius V to pull a small aluminum Kayak trailer and for hauling bikes . The hitch was super easy to install (had my daughter help) and the wiring harness was a piece of cake. I was done with both installations in under an hour without rushing. The ground clearance for the hitch is good and has a nice low profile, it actually doesn't look out of place on the vehicle.

Being the Prius V"s wiring is different then most U.S. Cars this is just the product needed to be able to pull a light weight trailer that has E-Trailers L.E.D. lights installed

This was super-easy to install in my 2016 PriusV! No wire cutting, very few panels needed to be gently coaxed into a new position momentarily, and while installing I even discovered a bung in the bottom of the spare tire well that allowed me to route the wiring outside the car via an inconspicuous route.



by:

Great product with easy install instructions. No wire splicing required! Only problem was with the double sided tape to mount the converter box wasn’t strong enough. Seemed like it lost its adhesion ability due to heat



by:

You had sent me 2 of the Towready and neither one would work.

I received the Curt harness at 3 pm today and in about 30 minutes

it was installed and worked perfectly. Thank you for making this

right.

This is made excellent, was exactly what I needed for my 2014 Prius V. Was very easy to install, only took about fifteen minutes to complete. Definitely plug and play is the way to go for any wiring installation.

Second time ordering a product from e trailer. Very impressed with tracking emails. Easy installation video available on the web site.



by:
2014 Toyota Prius V

The installation is very straightforward and easy. And while a large part of the ease is related to the manufacturer, this install kit makes it about as easy as it possibly can be.

Curt always has quality products. No wire cutting, just plug an play with this kit.

Wow! Product was received a day after I ordered it and with the online do it yourself video I was able to complete the installation myself. Everything went exactly as shown and explained in the video.

Thanks so much!

  • Will Carpod Cargo Carrier for 2-Inch Hitches M2205 Fit a 1-1/4-Inch Hitch on 2012 Toyota Prius V
    The Carpod Walled Folding Cargo Carrier for 2" Hitches, part # M2205, will fit into the 1-1/4-inch hitch receiver on your 2012 Toyota Prius V wagon only if used with an adapter. The problem with using hitch adapters is that they reduce the hitch weight capacity by half. The hitches we offer for your 2012 Prius V are all light-duty Class I hitches which are rated for a tongue weight of 200-lbs. The link provided will show you all of these. If an adapter is used the hitch capacity drops...

  • Will Hitch and Wiring Harness from 2013 Prius V Fit on 2016 Prius V
    The same Class I trailer hitches that fit the 2013 Toyota Prius V also fit the 2016 model year. Those hitches are shown on the linked page, Curt # C11276 and Draw-Tite # 24847. You will need to replace your installation hardware since this is intended only for a single use. Hitch mounting hardware cannot be re-used to install the hitch on a new vehicle. We offer replacement hardware kit # RHK. Just click on the link for RHK and enter your hitch part number and manufacturer in the fields...

  • How to Add Reverse Light Circuit to Curt Trailer Wiring for 2012 Toyota Prius V
    If you wanted to add a reverse light circuit to the part # C56156 you would also need the part # 20036. The blue wire of this would run to the reverse light circuit of your Prius v which would give you the fifth circuit active for back up lights. Aside from that the 4-way would just plug right into this adapter.

  • Trailer Wiring Harness Availability for the 2012 Toyota Prius C
    I spoke with my contact at Curt and he told me that there is a wiring harness that is compatible with your 2012 Toyota Prius C, but the Curt T-Connector wiring harness, # C56156, will not fit your vehicle. This harness was only designed to fit the Prius V. For your Prius C, you will need the Curt Wiring Harness, # C59496. At this time there are no plug-in wiring harnesses available for your vehicle, so this harness will need to be hardwired. I have attached the installation instructions...

  • Trailer Wiring Harness Recommendation for a 2015 Toyota Prius V
    The Curt Wiring harness # C56156 that you referenced has been designed and tested for use on a 2015 Toyota Prius V. It will work with your taillight configuration. It actually only uses the taillight circuits as signal wires and draws the power for the taillights from the vehicle battery.
