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 tail lights. You will have to remove the trim access cover, scuff panels, and tail lights to access these connection points. Once you've plugged in the T-connector, run the hot lead to your car battery, which can be found in your trunk on the passenger's side. 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.


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.

This harness was a simple plug and play. . Hardest part was running positive wire to the front to the battery. No easy on a fat boy. But got it. Only complaint was the green wire with harness to the passenger side needs to be at least a foot longer. I actually added 2 feet on mine and gave me plenty of room to work. Great product th

Ordering from Etrailer is always easy and customer service is above par always. I have NEVER had a bad experience when calling fir assistance on a particular part or placing an order.

I do enjoy watching the videos prior to doing an install to assist with any questions that might have arose while in the process. The system Etrailer has us top notch!

It has performed very well and the excellent installation video was all that was needed to install the frame hitch and wiring kit. The Curt wiring kit, as your tech explained has just enough wire to be long enough to make the plug into the tail light. If you fail to know that in advance it is easy to route the wiring where it would not reach. This was by far the easiest frame mounted receiver style hitch and wiring kit we have installed so far. The height of the Jeep frame allows the entire installation of hitch and wiring to be done without the use of our wheel ramps. Let me touch on an issue that William mentioned, the use of a Swagman platform wheel mount hitch on a Jeep with spare tire mounted in the center of the tailgate on newer Wranglers. This position creates two challenges whether you use the Allen style top tube support style or the one I we installed. The Allen style require the backup camera to be relocated as the bike rack center pillar will obscure it, the Swedman wheel mount style requires use of a 2" to 11/4" extension plus the wheel brackets must be removed and turned upside down to allow the spare tire and tailgate to open completely. Lastly, IMHO all Swedman racks with 1 1/4" mounting frame should be supported with a cable under tension at the highest position possible to relieve the forces created by bicycle weights within specs. As e-assist bikes become more popular it is very easy to exceed the design weight of rack construction. Even two Huffy beach cruiser bikes that are within rack weight design put a lot of stress on this style rack. Not going to debate this issue, had a failure of the center support 1 1/4" beam years ago with significant damage to the two road bikes when beam structurally collapsed.

Hi William, I'd like to get a little more detail on how this wasn't a direct fit. I have linked the installation video and at about the 6 minutes mark you can see this harness will connect to your taillights. Does your plug resemble the one in the video?



by:

I'm still waiting for a refund on the one that was wrong that I had to reorder a new part and pay for it so I'm still waiting for money back

Super easy wiring job if you have a crawler. The instructions on the etrailer site made the entire thing a breeze. Still working great a year later.

  • Is 12 Volt Outlet Needed For Curt 4-Way on 2024 Jeep Wrangler
    I'm sorry I don't quite understand what you're asking.

  • Does Curt Wriing for a 2024 Jeep Wrangler Require Connecting the Power Wire to the Battery
    Yes, the Curt T-Connector # 56407 will require you to route a power wire from the black module box to the battery on your 2024 Jeep Wrangler. I know it isn't convenient, but it's the best setup when it comes to a trailer wiring harness since this tees in behind your tail lights and then powers your trailer lights via the battery in your Jeep. The separate 12V power wire powers your trailer lights but also doubles as a way to protect the OEM wiring on your Jeep.

  • 4-Flat Trailer Wiring For 2024 Jeep Wrangler With Tow Bar Wiring
  • Trailer Hitch and Wiring for 2024 Jeep Wrangler with Tow Bar Wiring
    Hey Bill, for your 2024 Jeep Wrangler we have the Curt trailer wiring kit part # 56407 that is a confirmed fit but we don't have anything that plugs into factory trailer wiring. This kit installs inline with the taillight wiring like the tow bar wiring kit you have now. This installs in the exact same way basically and is completely compatible with it. Then for a hitch the etrailer hitch part # e98856 is a fit and a great option. If you were really wanting to use the factory trailer...

    We generally use a bracket like the Mounting Bracket # 18144 to permanently mount a 4-flat plug. You can use a few self-tapping screws to mount in on the bumper, or really wherever you want. We usually will attach the bracket to the cross-tube of the trailer hitch.

  • Will Curt Trailer Wiring Harness part # 56407 Drain Car Battery
    Hey Jason, it sounds like you are maybe asking if the Curt trailer wiring harness part # 56407 could possibly power the taillights of your vehicle due to a parasitic draw you are experiencing? If so, this could do that but it wasn't intended to do so. If instead you were asking if this can be used for trailer wiring without draining the battery of the car it is installed in the answer to that is yes. It would not drain the battery if left installed.

  • Can 7-Way Adapter Power Wire Be Same Wire as 4-Way Converter Box
    You actually don't have to run a power wire to the Curt 7-way adapter part # C57672 unless you need the circuit for like a battery charge or interior/exterior lighting on the trailer. If you don't have a need for that you can leave that circuit unconnected. Otherwise I would have to recommend using a separate wire from the converter box power circuit. One easier solution would be the # 10-2-1 which is a double bonded 10 gauge wire that basically allows you to run one wire but it's really...

    Yes, you will! We get this question all the time. Even though there's a 12 v power wire ran to the back you still need a dedicated one run directly from the battery for the Tekonsha item # 118786 or the Curt item # 56407. The power module's are pretty sensitive and need a direct source of power from your Jeep's battery. In addition to that running it to the 12v accessory plug/cigarette lighter goes against the instructions so you would void your warranty and any protections you get from...
