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.


Tail Light Converter with Surface-Mount Technology

A tail light converter is built into this T-connector. 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.

Video Transcript for Curt Custom Fit Vehicle Wiring - Trailer Hitch Wiring - C55414 Review

Today we're going to review part number C55414. This is the Curt T-Connector vehicle wiring harness with the 4-way flat trailer connector. This is a custom fit part, it is designed to fit the 2006 to 2010 Jeep Commanders without the factory 7-way and it does exclude the Rocky Mountain Edition version. On a custom fit part what I always recommend is to go to our website, use our fit guide. Put in your model vehicle and it'll show you if this will work for the application. This does provide a 4-way flat trailer connector at the back of your vehicle to power your signal trailer lights. It does connect quickly and easily, there's no cutting or splicing of wires. I just use these plugin T-Connectors, and you'll just locate your connection points behind the taillights and plug these in. It does include this taillight converter, to ensure that your vehicle's wiring will match that of your trailer. The converter is constructed using the SMT technology which is Surface Mount Technology.

This will give you a consistent, reliable performance. It'll maximize your trailer light yield and intensity while producing minimal heat, and it also ensures superior operation in any rough road conditions. Also comes with this dust cap for the 4-way, so when you're not plugged in to your trailer you can use this dust cap, just install it on the 4-way, and put the dust cap over and that'll protect those terminals from any damage from the elements. This part is made in the USA, it does come with everything shown here. Comes with the harness, the dust cap, some cable ties to take up any length of the wiring, comes with a double face piece of tape that'll go onto your converter to hold that into place, a grounding screw, and then a nice set of detailed instructions with pictures. The specs on this. The maximum amperage on the stop and turn lights circuits are 3 amps per circuit, on the taillight circuit is 5 amps ...

Just real quickly, when you go to install this what you do is go to the back of the vehicle. The cargo area behind the taillight shell access, unplug the harness from the taillight. What you'll do is start on the driver's side and the T-Connectors that have the yellow wire in it, that will be for that driver's side. Once it's disconnected you'll plug this in between the taillight and the harness, plug them back in to this connector. You'll see it has a white wire on it with a I-LED on it, that's what you use this grounding screw for. If there's already a screw there that you can use, you can go ahead and do that.

If you need to make one just drill a hole using included grounding screw. Then these last set of T-Connectors that have the red and green wire, that's for the passenger's side and you'll see that's a length of wire so you'll run that over to the passenger's side, and do the same thing, unplug the harness from the taillights, plug this in between the harness and taillights. Then just run your length of bonded wire right here out to the back to the trailer, and plug it in to the 4-way when you're ready to use it, and when you're not just put the dust cap on it to store. That should do it for the review on part number C55414. The Curt T-Connector vehicle wiring harness with the 4-way flat trailer connector.

I did some research and etrailer was the best option for the price. I respect the fact that my selection was made in the USA. The delivery was prompt, and ordering made simple. You can watch the delivery progress by the tracking info they give you with your email order confirmation. I watched the etrailer video on how to do the install, which made it so easy to install. Watch out for those a little cheaper, because they are probably made in another country!

Once I figured out how to remove the taillight assemblies it was very simple to install. The wire length between the light assemblies is perfect, no extra wire to get rid of and not to short. A couple extra zip ties would be nice as there is plenty of wire to the flat plug I will need to stash somewhere. Always better than not enough.

The old one on my Jeep was wire splice type. Stopped working. Just about every wire had a lot of corrosion. Ordered this one because of the factory type connectors. Simple to install.



by:
2010 Jeep Commander

After going to Walmart and getting a subpar trailer harness I came across trailer. This harness is insanely easy to install, literally just plug it in, and it works perfect. Customer service was amazing and product was delivered the next day. HIGHLY HIGHlY HIGHLY recommend this product and the etrailer.com company!



by:
2010 Jeep Commander

Great product! It took me 30 minutes - if that - to install this in my 2006 Jeep Commander. It works perfect. This compared to a U-Haul installation that has been nothing but trouble for the last year. I ripped their mess out in 10 minutes. Wish I would have known about this product a year ago.
Thanks!

See what our Experts say about this CURT Custom Fit Vehicle Wiring

  • Trailer Wiring for 2007 Jeep Commander
    If your 2007 Jeep Commander was equipped with a factory tow package there is going to be a wiring connector on the inside of your driver side rear bumper that our part # 118381 plugs into. If you have that connector then this is the part you need for a 4-way. Use part # HM42190 for a 7-way. If you already have a hitch and no wiring it is likely someone installed the hitch and not the wiring and it's not factory installed. If it doesn't have a hitch someone could have taken off the factory...
