Contains all you need to make this work. Used it on my 2017 GLE350 that has LED tail lights using combined brake and signal lights. Figuring out the correct wires to connect to was a bit trial and error. Running the wire from the module to the fuse box below the rear passenger seat took some time as well. But the setup works without a problem. Wires: Brake (red): connect to ground. Lights (brown): right tail light, white with blue tracer. Right turn: right tail light, gray/black wire Left turn: left tail light, gray/black wire. Ground: at rear of the car, between tail light and spare wheel well. 12V power: below rear passenger seat, using the big screw connector/cable visible there. Good luck! 604471

converter and flat 4 wiring was fine. for my application, the green RH turn signal wire was over 2 feet too short to cross from one tail light to the other. really, add 3 ft to the wire, much less hassle. the power wire from battery to converter is ALSO TOO SHORT, by more than 5 feet. Since that part of the kit is really only the fuse holder and the wire, this was a waste of money. NOT AT ALL WHAT I WOULD CALL A UNIVERSAL FIT. 575011


Comments
This wiring harness part C59496 is considered a universal fit because it is not a plug and play custom fit application. It can be hardwired into many different vehicles. If you needed extra wire for your vehicle, I recommend part # DW02412-1
14 Gauge Primary Wire - Yellow - per Foot
$0.96
for extra 14 gauge wire.

  • Recommended Trailer Wiring Harness for 2013 VW Jetta SportWagen
    The EcoHitch # 306-X7284 is a great choice! In order to add wiring to tow your boat (those are really cool, by the way), you'll want to use the Tekonsha # 119179KIT which comes with a circuit protected Modu-Lite converter to help protect the electrical components on your vehicle. I recommend using the Tekonsha over the Curt # C59496 harnesses because the converter is a little bit more reliable and since you're likely going to have LED lights on your trailer, the slight difference in amp...

  • Installation of Wiring Harness on 2019 Hyundai Tucson
    The Curt Upgraded Circuit Protected Powered Tail Light Converter # C59496 will splice into the wiring behind the tail lights on your 2019 Hyundai Tucson. You'll likely need to open the rear hatch of your Tucson to access the area behind the tail lights; there should be some screws that allow you to remove the tail light housing and access the wires you need to splice into. You will also need to run the included heavy gauge wire to the battery and connect via the included ring terminal....

  • Comparing Curt Trailer Wiring Harnesses for 2007 BMW X3
    Both of the Curt wiring kits you referenced are a fit for your 2007 BMW X3 but the part # C59236 is a higher amp rated version. It is rated for 5 amps for the stop/turn circuit and 7.5 for the running lights. Whereas the # C59496 is rated for 3 amps and 6 amps respectively. What this means is that the higher rated version would withstand trailer wiring shorts better before damaging itself.

  • Trailer Wiring Harness for a 2019 Hyundai Tucson Ultimate
    The trailer wiring harness I recommend for your 2019 Hyundai Tucson Ultimate is the Curt Upgraded Circuit Protected Powered Tail Light Converter part # C59496. This kit will work with LED tail lights so you should not have any concerns. It will splice into the tail light circuits on your vehicle and provide you with functions for a 4-way trailer connector. It also comes with all of the wiring connectors you will need as well. Unfortunately, there are no custom fit trailer wiring harnesses...

  • Can the 12 Volt Power Wire from a Trailer Wiring Harness Tap Into a 12 Volt Accessory Outlet
    I strongly recommend running the 12 volt power wire from the Curt Wiring Harness, # C59496, directly to the vehicle battery. The 12 volt accessory circuit was not designed to support the additional load of a trailer wiring harness. A wiring harness must have its own dedicated circuit directly to the battery. We have seen many instances where customers have tapped into a 12 volt accessory circuit, like a car lighter socket, and the harness failed. We have also seen instances where the accessory...

    In order to install a brake controller on your 2003 Monaco Knight motorhome you will need a 4-way trailer connector, 4 to 7-way trailer connector adapter, and a brake controller. There will also be some loose wires and circuit breakers needed but most kits come with this.

  • Should Red Wire of Curt Universal Wiring Kit be Grounded for Jeep JL with 3-Wire System
    If your Jeep JL has a 3-wire system then you will actually attach the red wire from the Curt Upgraded Circuit Protected Powered Tail Light Converter w Hardwire Kit # C59496 to the brake light circuit. The only time you will ground the red wire is if your Jeep JL is a 2-wire system. You can tell the difference by checking to see if the same circuits are used for both your stop and turn functions. If they do then it's a 2-wire system but if they don't it's a 3-wire system. This wiring...

  • Running Lights Will Not Work on Trailer Towed with a 2012 Dodge Journey
    Almost all trailers do use 2 wire system. The 2 wire system means there is one wire for the running lights on each side of the trailer and one wire for the turn signal and brake light. It is likely that both of these wires are running to the dual filament bulbs. The brake light and turn signal will use the brighter or higher intensity filament and the running lights will use the dimmer or lower intensity filament. To troubleshoot your issue, I recommend starting at the trailer connectors....

  • Tow Bar and Wiring Harness Recommendation for a 2003 Land Rover Discovery
    I did some research on your 2003 Land Rover Discovery and I could not find any information regarding the ability to flat tow your vehicle. I recommend checking your owners manual to make sure it is safe to flat tow your vehicle behind your motor home. Vehicle manufacturers will often place restrictions on vehicles when towing them behind another vehicle or motor home. If you find that it is okay to tow your Discovery, then you will need tow bar wiring like the Roadmaster Universal Wiring...

  • Will the Curt Powered Wiring Harness # C59496 Support LED Trailer Lights
    You can certainly upgrade the tail lights on your trailer to LED tail lights. LED tail lights will draw a fraction of the power that incandescent bulbs require which results in less work for the converter of your Curt Powered Wiring Harness, # C59496. There will not be any compatibility issue between the LED trailer lights and the powered wiring harness on your 2011 Volkswagen TDI. I have attached a link to all of our LED tail lights for you to check out. If you would like to send...

  • Is Curt Powered Tail Light Converter Kit Compatible with a 2014 BMW X1
    The Curt Upgraded Circuit Protected Powered Tail Light Converter w Hardwire Kit # C59496 actually replaced the discontinued part 56146 and the Powered Converter Wiring Kit # 55151 that you have. Both of these are compatible with your 2014 BMW X1 which you can see from the attached installation video of the older kit you have on a 2014 BMW X1. The thing about this kit is that its a universal fit since you splice the wiring in so it is compatible with just about any vehicle out there.

  • Does 2006 Lincoln Town Car Need Trailer Wiring Harness with Power Ran From Battery
    Not all vehicles can handle the additional amperage draw of the trailer taillights on the vehicle taillight circuits. Those vehicles need setup that draws power from the battery. Some vehicles have higher rated circuits that can handle this, and others need to have the power drawn straight from the battery to protect the taillight circuits. For your 2006 Lincoln Town Car you need to install a harness that draws power from the battery to protect the taillight circuits. For that you would...

  • Can you Route a 4-Way Trailer Connector Under the Vehicle on a 2009 Volvo XC70
    Many vehicles will have grommets somewhere in the rear cargo area that will allow you to route wires to the underside of the vehicle. The grommets are typically found behind the rear trim panels, in the spare tire well, or under the threshold. When we installed the Curt Wiring Harness Kit, # C59496, on a 2011 Volvo XC70, we found a grommet just under the spare tire (see photo). The 2011 XC70 is the same generation as your 2009 XC70, so you should have this grommet as well. Sometimes...

  • Trailer Wiring Harness Recommendation for a 2012 Kia Sorento
    The main difference between the Curt Modulite Wiring Harness, # C59496, and the Curt T-Connector Wiring Harness, # C56328, is that the T-Connector harness, # C56328, simply plugs into the factory tail light connectors at the back of the tail light assemblies. The Modulite Harness, # C59496, needs to be hardwired into your vehicles tail light circuits. I recommend using the T-Connector Harness # C56163 because you will not need to cut or splice into your vehicles tail light wires. Both...
