  • Custom Fit
  • Trailer Hitch Wiring
  • 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.

  • Provides a 4-way flat trailer connector at the back of your vehicle to power your trailer's signal lights

    • Tail lights: 6 amps per circuit
  • Limited 1-year warranty


Installation

This custom-fit T-connector plugs into your vehicle's wiring harness, which is located in your cargo area. You will have to remove all trunk floor coverings, storage trays, and the scuff panel to access these connection points. Once you've plugged in the T-connector, run the hot lead 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.


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


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.

Works great. Easy to install and tuck everything away when not using to keep from weather. No problems with trailer lighting from either occasional [moving] trailers or personal trailer.

I really like the way the stealth hitch is hidden when not in use on my Volvo XC90.

Unable to finish the battery hook up to the wiring. I have "T8" Xc90, Hybird, battery connections are not the same as any information available, unsure at the moment how to proceed, do not want to loose any settings if I take off connections.

Works great,easy install.

As advertised,this harness is a snap to install.
I did also added a”P”clamp to the harnesses at the light assemblies to tuck everything in tight.

Works great!!

  • Recommended Trailer Hitch for 2017 Volvo S-90 T6
    For your 2017 Volvo S-90 sedan with T6 trim (whether the T6 Momentum or the T6 Inscription), the Curt Trailer Hitch Receiver # C13305 is a confirmed fit. It is a bolt on installation with no drilling required but there is some rear fascia trimming required. I've attached the installation details to assist. If you are interested in wiring for towing or accessories, I recommend the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector # C56285 which is also a confirmed fit.

  • Trailer Hitch and Wiring for a 2016 Volvo XC90
    For your 2016 Volvo XC90 you can use Curt trailer hitch # C13233. This is a Class III trailer hitch with a 2 inch receiver. It is rated for 900 pounds tongue weight and 6,000 pounds gross trailer weight. Be sure to check the vehicle owner's manual for the XC90 capacity and go by the lowest rating. If you plan on doing some towing I 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....

  • Is Bumper or Fascia Trimming Required to Install Curt Trailer Hitch on a 2016 Volvo XC90
    To install Curt trailer hitch # C13233 on your 2016 Volvo XC90 there is an underbody heat shield that will need to be trimmed, see the linked instructions, but the fascia/bumper does not have to be trimmed. I have included a picture of what the hitch looks like once installed. You can see that the bumper and other pieces remain intact. If you plan on doing some towing I recommend etrailer ball mount kit # 989900. It comes with 2 ball mounts; one with a 3/4 inch rise or 2 inch drop and...

  • Trailer Hitch and Wiring Recommendation for 2018 Volvo XC90
    For your 2018 Volvo XC90 the Draw Tite hitch part # 76194 is the correct fit and the one you'd want. The second part number you mentioned isn't active and the part # 75152 is for older versions of the XC90. For trailer wiring you'd then want the Curt # C56285 which is a confirmed custom fit that will install easily. 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...

  • Trailer Hitch and Wiring for a 2018 Volvo XC90 T8
    The available trailer hitches for your 2018 Volvo XC90 will require varying degrees of vehicle modification for installation. Draw-Tite hitch # 76194 does not require any drilling but does require some fascia trimming and heat shield modification. I have linked the instructions and a video showing an example installation. This hitch is listed as a fit for all styles of the 2018 XC90 including the T8. Curt hitch # C13233 does require drilling but does not require trimming the fascia. It...

  • Trailer Wiring Harness Fit for 2017 Volvo V90cc
    Although it's conceivable that the Curt # C56285 could fit the 2017 Volvo V90, they haven't tested the fit so they cannot confirm if it'll work for you. I'd recommend going with a universal fit harness like the # 119147KIT which will without a doubt work for you. The install will require some splicing, but the installation isn't too difficult. I'll link to a video with more details.

  • 2017 Volvo XC90 Trailer Hitch and Brake Controller Recommendation
    First let's start with a hitch for your 2017 Volvo XC90. The Draw Tite hitch part # 76194 that you referenced is the way to go as it only has a visible crosstube. Now for a brake controller there's no reason you couldn't install an aftermarket one from us and not worry about it affecting any safety programs on your vehicle. I am not sure what the guy at the dealer was thinking but our controllers install totally outside of the computer of the vehicle so there would be no interference....
