I thought this was going to give me trouble. But, watching the video beforehand made it very easy to install. Took less than 20 minutes. The hardest part was drilling a pilot hole for the ground screw due to limited access within the tail light housing. 756453

Product arrived on time and was packaged well. The wiring harness was very easy to install on my Jeep Wrangler. I only made one change and that was to bolt the ground wire instead of using a self tapping screw. It was solely for my piece of mind knowing it wasn’t going to vibrate loose over time. 717736

Ask the Experts about this Curt Custom Fit Vehicle Wiring

  • Can I Use Hopkins HM56200 With Curt Trailer Wiring C55124 On 2016 Jeep Wrangler Unlimited
    I recommend the Curt Trailer Hitch Receiver part # C13392 for the 2016 Jeep Wrangler Unlimited because it is longer compared to the other options to clear the spare tire if you ever decide to carry a bike rack or cargo carrier. I have attached an installation video for your reference. The Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector part # C55124 for the 2016 Jeep Wrangler Unlimited without tow package plugs in line with the Hopkins Tow Bar wiring part...

  • Parts Needed to Flat Tow a 2016 Ford C-Max
    The easiest system to set up and use is the Blue Ox Patriot # BRK2016, that applies the vehicle brakes in proportion to how much the tow vehicle is braking. This is the safest way to stop and it reduces wear and tear on both vehicles. For a base plate kit I would recommend the part # 524432-1 which I attached an install video for as well. The most popular compatible tow bar is the Falcon 2, # RM-520. For safety cables you can use # RM-643. The coiled design helps keep the cables...

  • Which Curt T-Connector Fits a 2018 Jeep JL Wrangler
    We do have a Curt T-Connector that fits a 2018 Jeep Wrangler JL but the part # C55124 that you referenced does not fit. Instead you need part # C56407 which tees in behind your tail lights and then draws power directly from your battery via the included black wire. The great thing about drawing power directly from your battery is that your vehicle wiring is completely protected in the event that something goes wrong with your trailer wiring. Attached is an installation video of this...

  • Best Tow Bar Wiring Harness Recommendation for a 2015 Jeep Wrangler Unlimited
    For tow bar wiring for your 2015 Jeep Wrangler Unlimited you are going to want the part # HM56200. This harness installs easily by plugging in line with the taillights of your vehicle. I attached an install video for you to check out as well. The # C55124 that you referenced is trailer wiring and would not work for what you are doing.

    The # C55124 and # HM42635 trailer wiring harnesses we offer for your 2011 Jeep Wrangler Unlimited are installed the same way on your vehicle. Both provide you with the tail, turn, and brake light. The Curt harness has a 1-year warranty while the Hopkins wiring harness has a 90-day warranty. The harnesses plug into the vehicle wiring located behind the tail lights To install these harnesses you will need to remove the tail light assembly to get to the wiring.

  • Parts to Add Trailer Hitch, 4-Flat and Tow Bar Wiring to 2015 Jeep Wrangler
    There is a way to add a trailer hitch, 4-way and tow bar wiring to your 2015 Jeep Wrangler but you will want to use something other than the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56200. The reason for this is the Hopkins kit requires the same plug-in connection points as adding a 4-way so they are not going to be compatible. What I recommend instead is using the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit # RM-15267 which will splice into your Jeep's...

  • Part Needed to Convert 2011 Jeep Wrangler Unlimited from 4-Pole Flat to 7-Way Trailer Socket
    If you already have a working 4-pole flat trailer connector on your 2011 Wrangler Unlimited you can easily convert this connector's lighting signals into the round RV-style 7-way format. You will use part # 37185 from Hopkins, which is a combination 4-pole and 7-way in one unit. This lets you retain both connector formats on your Jeep. This Hopkins part includes a metal mounting bracket, installation hardware and connectors to allow you to make additional circuit connections on the 7-way...

  • How To Tell If a 2017 Jeep Wrangler Unlimited Has the Tow Package
    In order to determine the correct trailer wiring harness and brake controller for a 2017 Jeep Wrangler Unlimited you need to know if you have the factory tow package. This should clearly be marked on the window sticker but if you don't have any factory hitch or wiring in place then odds are you don't. I recommend the Curt T-Connector Vehicle Wiring Harness part # C55124 with the Universal Installation Kit for Trailer Brake Controller part # ETBC7 and Curt Echo Wireless Trailer Brake...

  • Trailer Hitch for a 2016 Ford C-Max
    The most popular trailer hitch for your 2016 Ford C-Max is Curt hitch # C12092. This is a Class II trailer hitch with a 1-1/4 inch receiver. If you want to use the hitch for an accessory such as a bike rack or cargo carrier then you have to make sure the accessory is rated for use with a Class II trailer hitch. Curt also says you have to use stabilization strap # 18050 when using this hitch for any non-trailer load (such as a bike rack or cargo carrier) per their warranty requirements. If...

  • Plug was Destroyed on Curt T-Connector Vehicle Wiring Harness # C55124 for 2014 Jeep Wrangler
    If you destroyed one of the plugs at the end of your Curt T-Connector Vehicle Wiring Harness, # C55124, then this wiring harness will need to be replaced. Replacement plugs are not available. If it is the factory plug that was destroyed you will need to contact your local Jeep dealer for a replacement.

  • Parts Needed to Install Prodigy P3 Brake Controller in 2018 Jeep Wrangler Unlimited
    Since the 2018 Jeep Wrangler does not come with factory brake controller wiring you'll have to hardwire in your P3 part # 90195. You will need to start with a 4-way (if you do not have one). For that you would want the # C55124. From there you would need to convert the 4-way to a 7-way so that you can install the brake controller. For that you will want the Brake Controller Install Kit and 7-Way Adapter part # ETBC7. I attached installation instructions and an install video for this...

  • Troubleshooting 2013 Jeep Wrangler Unlimited Wiring Issue with Curt 4-Way Harness
    Sometimes the issue with a wiring harness like what you have with the C55124 is an issue with the factory wiring. Other times it is with a bent pin in the connection. Other times it is a bad ground connection, and then there can also be a wiring short. You will need to do some troubleshooting using a circuit tester like # PTW2993. This tester will allow you to check the functions of your factory wiring. My recommendation is to unplug your harness and check all your factory wiring...

  • Recommended 2-Inch Hitch and Wiring for 2015 Jeep Wrangler Unlimited
    For a Class III hitch I suggest the Curt # 9883544. This will install on your Wrangler Unlimited as long as it is not one of the Limited Edition or Special Edition models. No drilling is needed. Temporary lowering of the exhaust for easier access to the mounting points and removal of tow hooks, if they are present, are required. The entire installation process is shown in the linked video; this shows your same year and model Jeep. For wiring, you'll start with a 4-pole harness, part...

  • Recommended Trailer Hitch Receiver for 2018 Jeep Wrangler Unlimited JK and JL Models
    All of the JL Wrangler Unlimited hitches we carry will work on the JK Wrangler Unlimited models, but there are some JK model hitches that are not compatible with the JL Wranglers based on fit guide from the manufacturer because they have a shorter receiver. The bolt mounting holes are in the exact same location. Unless you are doing rock crawling, I recommend getting the longer receiver like the # e98856 or Curt # C13392 which will allow more accessories such as bike racks and cargo...

  • How to Mount 4-Way Connector with Curt Trailer Hitch # 9883544 on a 2016 Jeep Wrangler
    There are a few different options for storing the Curt T-Connector # C55124 on your 2016 Jeep Wrangler. The first couple of options are exactly what you mentioned, you can let it hang there or zip-tie it, but either of these options don't look that great. We do have the mounting bracket # 18144 which can be mounted to the body of your Wrangler but I believe you are looking for something like the Easy Mount Bracket # C58001 which basically clamps around the receiver of your Curt Receiver...

    It is easy to recommend the Tekonsha Prodigy P2 Brake Controller # 90885. Our customers consistently rate this item very highly for its easy installation and reliable operation. Plus it has the capability to work with both electric drum brakes and electric-over-hydraulic actuators. If you care to trade up then I suggest the P3 controller # 90195 which has the same capabilities but which includes an easier-to-read digital display. Both are proportional type controllers that will slow your...

(Towing Capacity: 350 Pound Tongue Weight // 3500 Pound Towing) Be sure to check your owner's manual for your Jeep's tow rating by the way. Installation video attached.

The Roadmaster Tow Bar Cover # RM-055-3 is a confirmed fit. For the rest of your wiring, I recommend the Hopkins Custom Tail Light Wiring Kit for Towed Vehicles # HM56200 and then cut and hardwire the 4 way into the 6-way connector # A10-6034VP using heat shrink butt connectors # DW05743-5.

  • Hitch Cargo Carrier, Cargo Bag, Light Kit and Lock Recommendations for 2014 Jeep Wrangler
    Selection of a hitch cargo carrier that will fit nicely at the back of the vehicle is best done after taking one simple measurement. Measure from the center of the hitch pin hole back to the rear-most part of the vehicle, which is typically the back edge of the rear-mounted spare tire on a Jeep like your 2014 Wrangler. You can refer to the linked article for illustration of how to measure. The Curt hitch cargo carrier # C18153 will require 10-inches of clearance when folded up and 20-inches...

    The 7- and 4-Pole Connector # HM40975-11933 will not work for you since you do not have the factory tow package. You would need to install a 4-way # C55124 in order to connect trailer lights. For the use of a brake controller you would also need the Universal Installation Kit for Trailer Brake Controller # ETBC7.

    You will need to start with a 4-way (if you do not have one). For that you would want the # C55124. Now if your trailer does not have brakes all you would need is the part # 37185 as an adapter to convert the 4-way to a 7-way. This gives you the ability to have a 4-way too. If you do have trailer brakes you would need the # ETBC7 instead of the # 37185 and a brake controller. This kit comes with everything needed to wire up the 7-way and install a brake controller.

  • How to Transport 333-lb Wheelchair on 2016 Jeep Wrangler Unlimited with Rear Spare Tire
    The spare tire on your 2016 Jeep Wrangler Unlimited poses a clearance challenge for transporting a wheelchair on a hitch-mounted carrier. The use of a hitch extension like # C45791 will get you an extra 8-inches of clearance at the spare tire, but the use of any adapter like this also costs you 50-percent of your hitch capacity. This is due to the extra leverage applied to the hitch from the load being further away from it. The 2-inch hitches for your Wrangler Unlimited (shown on the...
