CURT Custom Fit Vehicle Wiring

  • Custom Fit
  • Trailer Hitch Wiring
  • 4 Flat
  • No Converter
  • CURT

Quickly and easily install a 4-way trailer connector on your vehicle with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required.


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 - no cutting or splicing of wires
    • Locate connection points behind tail lights
    • Plug in T-connector
  • Comes with dust cap for 4-way flat connector
  • Limited 1-year warranty


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 tail light assemblies to access this harness.


Once installation is complete, the 4-way connector will be stowed beneath your vehicle, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.


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.

The trailer wire harness was a perfect fit. The installation video was helpful and I confidentally removed the tail lights, cinne cted the harness and in 15 minutes was done. Everything fit perfectly, instructions were clear and the video was a blessing. I highly recommend this product and your company fir the fast shipping of a quality product.

2008 Jeep Grand Cherokee

I ordered this wiring harness for my 2008 Grand Cherokee and it arrived very quickly. It installed very easily. The instructions are very clear, the only thing I would add is to be careful routing the wire to the right side vehicle light because you are running the wire close to the exhaust. The vehicle wiring has heat shielding covering the wiring harness but the trailer wiring does not, so be careful to keep it as far from the exhaust as possible. The connecters fit perfectly into the taillight connecters and all the wires were a good length, long enough to reach but not so long that there were a lot of excess wire to bundle up. Everything needed was included including a self tapping screw for the ground and zip ties to keep everything neat. I also ordered the 18144 mounting bracket and the plug fit into the bracket perfectly so I don't have a dangling plug.




by:

Great product. 10 min installment.

Works great still. Every installation should be this easy.

This product is top quality, and has held up in various weather conditions perfectly. One of the nice things about this wiring harness is that it has the appearance of being factory installed




by:
2012 Jeep Cherokee

Ridiculously easy to install. No hard wiring...just plug it in using the instructions. You pop both taillight housings out, pop the upper bulbs plug off, plug the new harness to bulb, plug cars factory plug into the back of the new harness. Route wires to the other taillight and do the same. Your flat 4 is now hanging under your bumper. Zip tie. Done. You do NOT need to flash the computer for a flat 4 harness addition even if your Cherokee had no towing package. It pulls is signal right from your working taillights...get it?




by:

I ordered this item and it arrived a few days later. It fit my 2011 Jeep Grand Cherokee just as advertised. I now have trailer lights that are fully operational. I called in for advice on which part to order and I was very impressed. Not only did a REAL person answer the phone. My sales tech knew what I needed and she explained why it worked the way it did. Thanks for everything etrailer.

Respectfully Yours




by:

Perfect fit. Easy installation.




by:

What can I say about etrailer.com and the Hitch Receiver... Communication was excellent, delivered in a matter of a few days, etc... The product was spot on; easy application taking less than a half hour. The hitch is snug to the bumper, sleek, and functional.

I'll be a repeat customer for sure!

Thank you, etrailer!




by:

The wiring installed very easily and mated with the light plugs perfectly. Based upon the size of the ground connector I would suggest a larger self tapping screw, which would make better 360 degree contact.

An option I would like to see and would buy is a square plate with mounting holes to fit the existing factory plug mount next to the hitch. A horizontal slot would be cut to match the shape of the plug with a long U-clip to hold it in place. Perfect!




by:
2007 Jeep Grand Cherokee

This product is high quality and installed easily according to video instructions. I got this with a hitch intended to haul a bike rack but I used it to pull a trailer and it works great. I always put some dielectric grease on the plug works great I would recommend it.

2013 Jeep Grand Cherokee

Wiring Harness is Excellent, Plug&Play. On my 2013 JEEP GRAND CHEROKEE LAREDO - I install it myself & learned about all the Nooks&Grannies in the rear of this JEEP. Roughted wiring harness through vent panels on the left & right rear side of the body, it took some searching with my fingers/hands, behind and under the bucket storage items. First - snaked a bendable wire through the panel/wholes to make sure that they arrived outside & inside the car skin - up to the rear tail lights & connect to the tail light wire. Everything working accordingly. No Blown Fuses. Jim C.




by:
2010 Jeep Grand Cherokee

Extremely happy with the wiring harness. Much better option that a generic harness at local auto parts store that requires spicing of wires for the installation. Easy installation on 2010 Grand Cherokee, good apparent quality and should be easy to remove/replace if needed due to the factory style connectors.

2013 Jeep Grand Cherokee

Hitch for 2013 Grand Cherokee. Items were rec. promptly as advertised. Installation was easy and the assistance from your employees was very helpful. Needed only one wrench. Instructions were adequate but did show a different model jeep taillight in the insts. All in all very easy installation and quick service. Wiring harness was easy to install also. Thank you.




by:
2016 Jeep Grand Cherokee

Easy to install. Plenty of wire to make install smooth and hidden. Does come with a cover for the 4 prong trailer plug. I would recommend looking under the vehicle. It may have a harness already wired under the bumper. It would allow you to just plug and go for a 4 or 7 prong. I had it but found the 4 prong flat was easy and a few dollars cheaper and I only need a flat plug.




by:
2015 Jeep Grand Cherokee

The hitch arrived on the date it was expected, the box was damaged and a portion of the hitch was sticking out of the box. Upon further inspection the hitch was fine. My son and I installed the hitch in about 10 minutes with no issues. We also purchased the wiring kit and we had that installed in about another 15 minutes on our 2011 Jeep Grand Cherokee. It looks great and works great. I would recommend this product.

Wiring harness was made with great quality. All connections connected correctly and worked as promised. Installation instructions were easy to read and follow and were complete.

This was very easy to install, works well. The wiring could have been a tad longer reaching the left tail light unit.

Super easy install just wish it came with extra fasteners for the tail lights or at least a warning that you would need them.

  • Dose 2012 Jeep Grand Cherokee Laredo Computer have to be Flashed to Install Trailer Wiring Harness
    No, you will not have to flash the computer on your 2012 Jeep Grand Cherokee Laredo to install and use Curt trailer wiring harness # C56009. If you wanted to, though not required, you could first disconnect the negative battery cable from the vehicle and then install the harness. I have included a link to the installation instructions for you.

  • Curt Custom Fit Vehicle Wiring # C56009 Recommendation for a 2011 Jeep Grand Cherokee
    The Curt Custom Fit Vehicle Wiring # C56009 that you referenced would be the correct wiring harness for your 2011 Jeep Grand Cherokee to provide you with trailer wiring. I attached installation instructions for this product for your to check out also. If there is a bracket on your factory hitch that is designed to store a 4-way wiring harness you should have no problem storing the 4-way from the # C56009 in that bracket.

  • Comparing Curt and Tow Ready Trailer Wiring for a 2013 Jeep Grand Cherokee without Tow Package
    Both the Tow Ready harness # 118425 and the Curt harness # C56009 install and function the same way on your 2013 Jeep Grand Cherokee without the factory tow package. They are just from 2 different manufacturers. I have linked videos showing example installations of both for you. I usually recommend Tow Ready over Curt because on harnesses with converter boxes the Tow Ready ones seem to be the more reliable option. But in this case there are no converter boxes so you could go either way...

  • Trailer Wiring Harness for a 2009 Jeep Grand Cherokee
    I don't even show a listing for a wiring harness with a converter for your 2009 Jeep Grand Cherokee. A converter is used when the vehicle has the turn signals and brake lights on separate circuits. It combines the signals because that is what a trailer uses. Some vehicles do not need a converter or a converter is recommended because of the sensitive wiring on the vehicle. Some converters are powered and draw power for the trailer lights directly from the vehicle battery. Others do not...

  • How to Determine if a 2007 Jeep Grand Cherokee has a Factory Tow Package
    The most definite way to determine if you have a tow package or not is to contact a Jeep dealership and give them your VIN number. They will be able to tell by looking at your VIN number whether or not you have the tow package. If you have a factory installed trailer hitch with either a 4-way trailer connector or a 7-way connector then you have the towing package also. The connector should be under the rear bumper on the driver side. If you find that you do not have the towing package...

It will be under the vehicle, behind the bumper on the driver's side of the vehicle. If you check out the video I attached you will see what the connector looks like.

    The camera on your 2011 Jeep Grand Cherokee should only come on when the vehicle is in reverse.

My aftermarket backup camera does have a volume control so the alert noise can be turned off. Otherwise, the only time it should bother you is when the vehicle is in reverse.

  • Recommended Trailer Hitch for 2013 Jeep Grand Cherokee
    I have a solution for you, but the Curt # C13900 is a multi-fit hitch, so it would likely take some modifications and drilling for installation on your 2013 Jeep Grand Cherokee. For this reason I recommend instead using the Curt # C13065 which is a custom fit for your Grand Cherokee, so that means no drilling and an easy, bolt on installation to save you time and hassle. This hitch is also a Class III receiver like the C13900 and uses a concealed cross-tube that really gives it a great...
