Video Transcript for Curt Wiring 55151 Review

Today we're going to review part number 55151. This is the Curt Powered Converter Wiring Kit. Now this kit will provide the wire that needs to be run to the vehicle battery to power the lights on your trailer. This kit is designed to work with all powered converter wiring harnesses and includes the necessary ring terminals, connectors to complete the installation of the power converter wiring harness. This is made to go with the part number 56146. I've got an example of that here. This is the powered converter right here. This part number will require this wiring kit to be connected to your vehicle.

Basically what you end up doing, this kit, first let me show you what it includes in this kit and then I'm going to show you how that wires up. This kit will include 20 feet of 12 gauge wire. It includes this inline fuse holder, a 10 amp fuse, a 3/8 inch diameter ring terminal, a couple of butt connectors, a grounding screw, some cable ties to take up any slack in the wiring and a large piece of double face tape. Basically when you use these parts to install your power converter, what you'll do is again, the double face tape is used to put on your converter, to attach it to a spot so it doesn't move around. Now there is a white wire that comes out of your converter with a ring terminal on it. You can use the grounding screw for that. Then the black wire is the power or battery wire that needs to run to the front of your battery. Just like that, so what you end up doing is you'll take this extra length of wire and you'll take one end of it, use one of the butt connectors and you'll attach that just like that. Then you'll run this length of wire up to the front of your vehicle to attach to your battery. Then the other end, see where the other ...

There it is, right there. Once you run this other end up there and before you attach it to the battery, you want to run it through this inline fuse holder. Again, you'll take another butt connector, attach it one side of the fuse holder and then on the other side you'll put this ring terminal and then that's what will attach to your positive posts of your battery. Then before you hook everything up, you just open up your inline fuse holder, take your 10 amp included fuse, push it into the fuse holder, put the cap back on it. Then you'll be all ready to go. Then like I say with these cable ties, if there's any wire hanging down, you can take it up with the cable ties. That's how this wiring kit would work with the 56146 power converter kit. That should do it for the review on part number 55151, the Curt Powered Converter Wiring Kit.


Customer Reviews

Powered Converter Wiring Kit - 55151

Average Customer Rating:  4.7 out of 5 stars   (18 Customer Reviews)


Have purchased a number of hitches and wire harness for a number of different vehicles I have owned. All products were easy to install and worked perfectly . The instructions were clear and quality of their products is top notch. I have used their customer service to ensure I was ordering the right product for a older vehicle (75 Toyota Landcruiser) they were patient and ensured I got the right set . Their customer service is matched by their pricing and that would be hard to beat . Delivery (Canada) was exceptionally fast. Probably not my last order and I have recommended this company and their products to my friends. If your considering a purchase I don't think you will be disappointed and you will be saving lots of money doing it yourself.


This is a very complex way to tap the taillight system to hook up two trailer lights but----- welcome to the 21st century.


Contained everything pictured and worked well for running power to the powered tail light converter


I did not need this as everything I needed was in the electronics kit. Your site said this was needed.


Just what is needed. Took one star off because the yellow battery crimp connector is a bit shallow, missed it and had to get another from autozone.


Very pleased with help in purchasing the right parts


This was very helpful with the install. Easy to run to battery underneath with car on jack stands.


yes,it is nothing more than 12ga wire plus a couple of terminals,
it comes 20' long most places only do 16' is easy to cut,
how do you stretch ?
besides,it was inexpensive to buy


Everyhting I ordered was shipped and received on time. I also had an installation question which was answered the next day. This is what I call great customer service from a company that sells quality products. Thank you.


It does what it says.


I purchased this, but never used it due to the fact that I ran power in a way that I didn't need it.

How did you run power if you dont mind me asking. Ready to install mine now

  • How to Determine if a Chevy Volt has a 2 or 3 Wire Taillight System
    The easy way to determine if your Volt has a two or a three wire system is to check the taillights. If the turn signal is amber in color, you have a three wire system. If your turn signal and brake lamp on each side of the vehicle use the same bulb, you have a two wire system. So, if your Volt has a two wire system you would ground both the red and the white wires from the converter to the vehicle. I've linked you to our trailer wiring FAQ article

  • Can Trailer Wiring Harness Power Wire be Connected to Outlet at Back of Vehicle Instead of Battery
    Only the battery should be used when installing any type of powered trailer wiring harness. Part of the reason is that it is not tested in any other way. A connection to the battery is reliable but going through some other circuit could lean to unforeseen and unwanted operation of the system. Plus, if the circuit for that power outlet at the back is fused with or otherwise connected to any other circuit then you will lose that level of isolation between the tow vehicle wiring and the trailer...

  • How to Determine if a Vehicle has a Combined or Separate Blinker/Stoplight Circuit
    The easy way to determine if your Volt has a two or a three wire system is to check the taillights. If the turn signal is amber in color, you have a three wire system. If your turn signal and brake lamp on each side of the vehicle use the same bulb, you have a two wire system. What you can also do is turn on your blinker and check to see which bulb activates. Now go back and put the brake on. Is it the same bulb that illuminates? If so, then the you have combined. If the bulbs are different...

    Yes, you will want to install an in-line fuse close to the battery when running a power wire directly from the battery to the converter.

This converter takes in separate stop and turn signals and outputs combined signals on the yellow and green (L & R) wires. You will also need Powered Converter Wiring Kit # 55151.

    I'm not sure which video you're speaking of, but I've confirmed with Curt that the # C56190 is indeed the correct taillight converter for your 2013 Q5. The # 55151 wiring kit is also needed to make the fused connection at the battery. I've provided you with a diagram showing an install diagram. There should be 5 wires exiting the 'input' side of the converter, a white ground wire, brown for running lights, yellow for left turn, red for brake light, green for right turn and black to the...

    You did indeed receive the correct parts. When we sell the Curt # C59496 powered taillight wiring converter we kit it together with the # 55151 power converter wiring kit. The wiring kit is used to run from the taillight converter box up to the positive battery terminal which provides power for the trailer taillights. The # C59496 wouldn't work without the wiring kit. I don't have a specific wiring diagram because the # C59496 is a universal fit product that fits hundreds of vehicles,...

  • Can I Wire My Curt Wiring Converter Kit Differently On 2010 Jetta Sportwagen
    You will want to wire the powered converter directly to the battery at the front of the vehicle so that there is a constant power source from the battery and not the vehicle's electrical system. The power wire is ran to the battery so that it is not pulling power from the electrical system but directly from the battery. In addition to running the power wire to the battery, you will need to use a circuit tester, part # 40376 to find the tail light functions of each wire. You will need to...

    Sounds like you are asking if it is necessary to run the power wire of the Curt Wiring Harness part # C56200KIT to the positive side of your battery since the part # 55151 is just the portion of the harness that runs to the battery. You will have to run this wire for the wiring harness to function properly. The reason it is needed is to protect the delicate wiring of your vehicle. The # C59236 uses the taillight circuits of your CC as signal wires only and draws all of the amperage for...

    Instructions do come with the Curt Powered Tail Light Converter with 4-Pole Flat Trailer Connector # C56190, and I have linked them for you to check out. However, this is a universal hardwire fit so the instructions are not specific to your 2008 BMW X5. What you will do, as you can see by the instructions, is use a circuit tester such as the very handy Cordless Circuit Tester # PTW2979 and find the circuits for the turn signals, brake lights and tail lights.

    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.

  • What is the Difference Between the Curt C56190 and C59236 for 2011 Audi SQ5
    I can see why this might be confusing. The Curt # C59236 is a complete wiring kit that comes with the wire to run from the converter module to the battery, where if you went with the Curt # C56190 you would also need the Powered Converter Wiring Kit # 55151 for the wiring and fuse to run to the battery. The Curt # C59236 also has a slightly higher amp rating for the tail lights/turn signals, so I recommend going with that-it's also a complete kit so there's no need to worry about adding...
