Curt Custom Fit Vehicle Wiring

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

Quickly and easily install a 4-way trailer connector on your vehicle 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
    • Locate connection points in rear cargo area
    • Plug in T-connector
  • 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


Specs:

  • Maximum amperage:
    • Stop/turn lights: 3.0 amps per circuit
    • Tail lights: 6.0 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's electrical junction box, which is located behind the driver's-side tail light. You will have to lift the storage lid in your cargo area and remove the panel on the driver's side to access this junction box. Once you've plugged in the T-connector, insert the 10-amp, low-profile fuse in position 2 and the 7.5-amp fuse in position 11 of the junction box (as shown below).


Fuse and wiring harness locations in junction box

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.


Powered 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.

Website was great---easy to determine what wiring was needed and how to install. Shipped quickly and arrived with hitch in 4 days. Instructional video on how to install was well done and easy to follow. Only comment would be on the ground wire.....I found a ground stud that was much easier to get to on my '15 MDX, than what was shown in the video. Found one on the frame on the side of the bumper and the ground wire was able to reach it. etrailer has been great. 940310

Product works well, not as hidden as say the factory trailer harness, but for the price it's great. Honda/Acura made it easy to install the accessories and this takes full advantage of that. If you go slow, within 15 minutes to install. quickly about 7. Basically taking the stuff out the trunk takes the longest part of the install. Would totally purchase again. 659097

Ask the Experts about this Curt Custom Fit Vehicle Wiring

  • Adding a 7-Way Trailer Connector and Brake Controller to a 2015 Acura MDX
    For many vehicles, including your 2015 Acura MDX, there isn't a plug and play type of 7-Way trailer connector so one has to be hardwired in. This is because on those vehicles the vehicle itself is not set up for a 7-Way trailer connector. To add one you would first need to install a 4-Way which will provide the light functions for the trailer. For your MDX you can use # 118628 to add the 4-Way. Then to add the 7-Way you will need # ETBC7. The 4-Way will plug into the ETBC7 leaving...

  • Is the Dealer Acura Relay Required to Install Trailer Wiring Harness on a 2014 Acura MDX
    If your 2014 Acura MDX did not come with the factory tow package then you would likely need to get the relay from an Acura dealer to install trailer wiring harness # C56192. It is possible though that an auto parts store would have an aftermarket relay. You can check your vehicle owners manual for the relay location to see if it is present on your model.

  • Installation of Curt Trailer Wiring Harness on a 2018 Acura MDX
    Yes, installation of the Curt trailer wiring harness # C56192 will be essentially identical on your 2018 Acura MDX as it is in the video for the 2016, linked for reference. That same goes for the Tekonsha wiring harness # 118628 which also fits your MDX. Please note that with either harness it may be necessary to see a local Acura dealer for a relay. The relay is needed to activate the tow package wiring circuit.

  • Fitment and Compatibility of Curt Wiring Harness on 2016 Acura MDX
    I spoke to my contact at Curt and he informed me that no additional relays should be needed with the # C56192 wiring harness. This is the confirmed wiring harness for your 2016 Acura MDX. He also told me that you would want to ensure the supplied fuses are in the proper location. Also be sure that the ring terminal on the ground wire is touching bare metal on the body. However you will need to check with the dealer that the MDX’s computer does not need to be flashed to activate the...

  • Why Does 2016 Acura MDX Call for 20 Amp Fuse But For Curt Trailer Wiring 10 Amp Fuse is Recommended
    I spoke with my contact at Curt and he said that you want to use the 10 amp fuse in the number 2 position on your fuse box. The factory Acura trailer wiring harness calls for a 20 amp fuse but with the Curt you have to use a 10 amp.

  • Is Additional Relay Needed When Installing Curt T-Connector Trailer Harness on 2014 Acura MDX
    Even if your 2014 Acura MDX doesn't have the factory tow package, the Curt T-Connector Vehicle Wiring Harness # C56192 and the fuses that come included should be all that you need to provide the Acura with a fully-functional 4-Way connector to power the trailer's signal lights. This is going to plug right into the vehicle's junction box behind the driver's-side tail light and the included fuses will be inserted into the correct slots as indicated in the instructions.

  • Trailer Hitch and Wiring for a 2016 Acura MDX
    Trailer wiring harness # 118628 fits both the 2015 and 2016 Acura MDX. I have included a link showing an example installation for you. For a trailer hitch the most popular option and what I recommend is # C13146. I have linked a video showing an example installation of the hitch as well. I also recommend 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 rise or 4 inch drop. It also includes a 1-7/8 inch ball,...

  • Installing the Curt T-Connector and Trailer Hitch Receiver on a 2015 Acura MDX
    The reason that we have the tech tip about possibly needing a relay from your local Acura dealer to properly install the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56192 is because over the years we have found that an insignificantly small amount of MDXs do not have this relay installed. It is a pretty rare thing and there is no rhyme or reason as to which ones do not have it. I even contacted some of our wiring harness manufacturers who hadn't heard of...

  • Recommended 7-Way Trailer Connector for 2017 Acura MDX
    I was able to find your invoice and confirm you have the Curt 4-way trailer connector # C56192. This does not work without additional components for towing a trailer with electric brakes. You will need to upgrade to a 7-way and add a brake controller. My recommendation for you is to use the 7-Way RV Upgrade Kit for Trailer Brake Controller Installation - 12 Gauge Wires # ETBC7L which will connect to your existing 4-way and also add 12v power from your vehicle battery. Then you can...

  • Recommendation for a Trailer Hitch Receiver and Wiring Harness on a 2014 Acura MDX
    The Curt Class III Receiver Hitch, # C13146, is a great choice for your 2014 Acura MDX and offers maximum towing capacity of 6000 pounds and tongue weight capacity of 900 pounds. It is a good idea to check your owner's manual to obtain your vehicle's towing capacity and follow which ever has the lowest weight capacity rating. The Curt Custom Fit Vehicle Wiring Harness, # C56192, plugs directly into the vehicle's existing wiring and should be a pretty easy install for you. Before you...

  • Parts Needed to Tow a 2016 Forest River R-Pod with a 2015 Acura MDX
    The Curt Trailer Hitch # C13146 along with the Curt T-Connector # C56192, the Wiring Kit # ETBC7, and a brake controller like the Prodigy P2 # 90885 or the P3 # 90195 is exactly what you need to tow with your 2015 Acura MDX. For a transmission cooler, the Derale # D13503 is a great option. You just need to make sure that you have room for it under your hood.

    Trailer hitches like the Curt hitch part # C13146 that you referenced are pretty easy to install for mechanics relative to the types of projects they have to deal with on a routing basis. Your best option would be then find a local mechanic to you with a good repuation and have them install it. I attached an install video for this hitch for you to check out as well.
