Video Transcript for Curt Wiring 56146KIT Review

Today, we're going to review part number 56146KIT. This is the Curt Upgraded Circuit Protected Power Converter with the wiring kit. This kit will include everything shown here on the table. It includes the circuit protected taillight converter. It is a power converter. It includes the wiring kit, and it'll even include a circuit tester to help you find the correct wires behind your vehicle taillights to connect this all to. This will adapt separate turn and stop lights which are on the vehicle it's usually a 3-wire system to a trailer that usually has a 2-wire system.

This will work with domestic and import vehicles. It'll virtually eliminate any draw on your vehicle taillight circuit. There is no heavy duty flasher required when using this. Now, this converter is battery-powered. You run the wire to your battery.

It is also circuit-protected. It does use the surface mount technology. Now, this will work with vehicles that have LED taillights, and it will work with trailers that have LED taillights. It does include everything shown here on the table. Basically, this converter, you notice it has a length of wire, usually about 58 inches long. Then it has a 4-way on the end of it.

This is what'll run out the back of your vehicle to plug into your trailer, and it will include this dust cover, which you'll be able to just install over there, so when you're not using the 4-way, what you can basically do is just pop this cover on it, and it protects the terminals from any damage and from the elements. It will come with this piece of 2-way tape, or two-face . double-sided tape that you can just put on here to attach your converter to a place so it doesn't move around. Then your wiring, you'll notice, it comes with the 4 quick-splice connectors for connecting your wires, and it comes with some cable ties to take up any slack in your wiring. Basically, this set of wires, it has the red, yellow, brown, and white. You run this to the driver side.

The white would be your ground, so you can use the included ground screw to ground it. The others would be tapped into your circuit, and then you run the green wire over to your passenger side, and that would be tapped into your passenger side taillights. The extra black wire is the power wire that would need to run to your battery to power this converter. The way you would connect that is you take your length of wire right here, and you'll take one of your butt connectors. Attach it to this power wire and then run it to the end of one of this wires here. Then you'll run this length of wire it's about 20 feet of wire they give you run this up to the front towards the battery. You don't want to connect this to the battery directly. What you want to do is put another butt connector on here. Then you'll connect the in-line fuse holder to this. Then on the other end of the in-line fuse holder, you'll take this ring connector and put it on there, and then this would connect to the positive side of your battery. Then before you use your wiring harness, what you want to do is open the in-line fuse holder. Take the included 10 amp fuse. Go ahead and install that into the fuse holder. Put your cap on there, and then you'd be all ready to go. Again, we mentioned it includes the circuit tester. What that's for is when you go to hook up these wires to your wiring harness, you want to use this circuit tester to test it, to make sure you're connecting up the right wires. That should do it for the review on part number 56146KIT. This is the Curt Upgraded Circuit Protected Power Converter with the wiring kit. .

Installing this kit in my 2010 Jetta Sportwagen (TDI) was not as easy as I hoped, but ultimately I was able to pull it off. I would have had much less confidence without the video. Routing the power wire from the spare tire well to the battery was the most time consuming part of the install. In the end the power wire ended up being juuuuuust the right length, but I used every inch of it. For most of the run I was able to rest the wire above various pieces of plastic splashguard (while still using plenty of zip ties), so it has some extra protection from the elements. Getting all the quick-connect splices done for the driver's side lights was tough. I didn't quite understand why in the video they didn't just feed the wires for the passenger side blinker, ground, and power from the lights to the trunk, which would put the converter box where it needs to be from the very start. Instead they recommend feeding the wires the opposite direction—from the trunk to the lights—and then you have to cram the converter box through the trim piece that has not been removed after connections are made. I did it that way too, thinking that maybe things would be less cluttered during the critical splicing step. It worked out okay, but if I did it again I'd probably do as I described and avoid having to shove the converter box through the trim. When I did that, one of the pieces of trim hardware popped off and disappeared somewhere below. One step I recommend adding whichever way you do it would be to peel the white ground wire away from the three it's attached to before feeding things from the trunk to the driver's side lights (or whichever direction you choose), which allows you to more easily connect the ground. As for the three splices on the driver's side, there is no play in the wires, the trim wants to spring back closed all the while, and for a regular two-handed guy who doesn't have much experience with DC wiring it was tricky. I did get all the connections made in the end, and I'm getting the right signals and voltage on all the connectors. I'm sure the video saved me hours and helped me avoid a lot of mistakes. 132574

I had the hitch and wiring delivered to a company that specialized and supposedly installed a lot of hitches. They have numerous locations, but only one did all of the hitch installs, about 15 miles from home. I brought my vehicle there so they could check that there would be no problems with what was shipped directly to their business, and I was assured that there would be no problems. They also gave me a firm estimate of two hours to complete the job. It turned out that no-one in the place knew how to do the electrical so the wiring was given back to me but they would not back down from the original price quote even though it was not finished and they recommended I go to another shop, not one of their shops, that REALLY works with hitches and they could do the electrical. Simply overpaying for the incomplete work plus "shop supplies" and taxes for labor (unusual in my state) was better than giving myself a heart attack. I've been cheated a lot when I was in business and always fought back and I treated vendors and customers with respect. I'm almost 80 now and I have a different outlook. I did go to the REAL trailer hitch installer that they recommended and they completed the wiring at a fair price, even though it was supposed to be done ad part of the original estimate at the first shop. None of this has anything to do with your product and "Your Product Review". I'll submit a photo of the car with the hitch installed. It does look like it belongs on the car and is not at all a distraction from the cars looks. Great product. You guys are great by delivering what was promised. The car is only a week old. You did great, and I love the finished installation if it doesn't fall off by being installed incorrectly. 127504

Wow....not an easy project for the Cadillac SRX. You have to do a lot of disassembly in the back to get to the wires and then try to get to the nuts holding the lights...good times. The directions were pretty good until I got to how to wire it up. Do I splice the wire, how does this work? Didn't know so I quit and put the components back together. Started at 8am and quit at 11am and I didn't even get the wiring hooked up. After I got it all put back together, I got a call from Tech Support telling me the wires don't get cut rather the blue splice connectors (splicing got me) are there for you to just put the wire in and crimp it down. I'd change that name and call them wire run-throughs or power connectors. When you say splice, I think I need to splice the wire. Good thing I didn't and quit. You should give yourself all day to get this project done if you haven't done one of these before. I have hooked up wiring on a dodge ram, pacifica and chevy silverado and were dead simple. This is not. A smart engineer out there needs to come up with an adapter that would use the plug from the taillight and allow the user to unplug the taillight, plug into the adapter and the adapter into the light. I think if you complete this project, you should get some kind of degree from ITT for wiring. 132100

I purchased this unit for my solara 05' and works very well. if you know how to locate your existing source of signals your fine. I mounted the control behind the plastic trim just inside the trunk where there were plenty of room. locating the turn signal wires and brake signals was not so bad. the contol was identifed very well for wire color and what it did. you pick up a completely seperate main power source from battery so you dont burden your existing circuits or fuses. I routed the hot wire under my car with the fuel lines which made it simple, used a spare tubing path that was empty. I get full lights, bright and worked first try. 89658


Its great, I am planning on putting another one on my old bronco as well.

So I missed the part about mounting the electronic pak on the driver's side. The wire for the passenger side signal is about 6 feet longer than the rest because it needs to reach over there. Don't make my mistake and mount the kit on the passenger side. It was a very simple and sweet installation, everything you need is in the kit and it fits almost anywhere behind the driver's side tail light. The installation video wants you to run the power wire outside and under the car--don't do that. I have an '05 civic and I popped the door channel trims and ran the power wire from the trunk thru the door channels and up behind the glove box. I used a sharpened coat hanger wire to carefully pierce the rubber grommet that surrounds the wire bundle from the ECU, gaining access to the engine bay just behind the steering rack on the passenger side. The battery is just forward of the strut tower from there and its easy to secure the new power wire. The kit works like a charm and its invisible with the wire tucked under the spare tire area. 135720

Overall it looks like this harness will work. A couple of points that are good to know. Splicing into the existing drivers side wires is extremely tedious work standing in a very awkward position just outside the tail gate. The scotch splicers just barely fit clustered together since there is no slack in the car wiring itself. There is very little guidance given on how to run the power line to the battery. A make/model specific schematic showing suggested attachment points would really help. The power tester that comes with the kit doesn't work by attaching to the little posts as shown in the video. Perhaps I'm doing something wrong, but compared to the video this project seems much more difficult and time consuming. Allow for plenty of time and don't rush this project. If you can get the car on jacks it will make running the power wire much easier. Definite room for improvement, but the product does work if installed correctly. 79777

I was very pleased with the product and the packaging. Since my vehicle was previously wired for a converter, I simply removed the fuse and tapped into the existing wiring, re-installed the new converter and cable tied the wires and converter in place of the old one. Pictures included. By the way, I will be 81 this coming September. 141476

The kit arrived with everything one would need to do an OK installation, provided your car was only two feet wide. The signal input wire for the right turn signal was very, very short. So short that I had to solder in a two foot extension to get it to reach accross my VW Golf (Mk6). The power wire was significantly larger than the unit's power wire and the fuse holder to which it must connect, it also came with butt connectors and no heat shrink or tape for strain relief. I ended up soldering and heatshrinking all power connection because it's just not worth having a hot wire flopping around the car to save me 5 minutes of work. Butt connectors fail. Always. I got this kit because it was half the price of comparable kits (still a ridiculous price for $3.72 worth of transistors and diodes), so I knew it would take some extra work. So far, I got what I paid for, nothing unexpected. Serviceable. 100412

This part gets the job done at a fair price, and with ease. The included voltage tester makes finding the proper wires a breeze, and the instructional video made the rest of the install a no-brainer. It was my first electrical project of any sort, nonetheless on a car, and I was done in less than a couple hours; including taking apart my trunk and putting it back together. Only thing I would change is using a longer wire to go from the module to the battery - the included wire doesn't have a lot to spare, and took a couple tries to make it all the way to the battery without having to add any wire. Not a real problem, but a little more length would have been a luxury. In the end, it works, and it's pretty easy to make it look professional enough that people could think the car came equipped with this from the factory. Good deal if you ask me. 41316

I bought this item to put on a 2003 land rover discovery II. Land rovers are notorious for adding things like this on. Thru the dealer it would have been well over $200.00. Product works well and had all the necessary parts for installation. My one point of advice if installing on a land rover is the ground. After installing per direction the unit failed to work and after talking with Bill in tech advice we both agreed it was the ground. The unit comes with a self starting sheet metal screw to ground it. Since you have to run the hot wire all the way up to the battery save yourself some time and just run a ground wire at the same time. Customer service and tech services were above and beyond and I would certainly buy here again as well as recommend. 152129

I bought this to install on our 2005 Subaru Legacy. The installation was pretty easy. The videos here on the website were very helpful to explain the installation process, as were the instructions that came with the harness kit. The harness just connects to the wiring for the tail lights on the back of the car and then you have to connect the control box to the battery, as well as the ground wire. The kit seems to be made very well. The blue splicing connectors are very easy to use and the circuit testor that came with the kit was quite useful. 142916

Works like a charm on my 2013 Toyota Prius , though it was a chore compared to the T-one connector by Tow Ready I installed on a previously owned Toyota Prius. Tow-Ready really needs to make that product for this year of Prius! Some tips- look up Ted K's install review of this on a Toyota Prius 2013, he told you which wire color is what light and how to remove panels access the light wires. The only thing I'd add is once you get to hooking it up and testing with the trailer lights, don't forget the last step, putting the fuse into the fuse holder! I had a short moment of disappointment before I realized I needed to do one more thing! Ta-dah! 138056

Just installed this harness (along with a hitch) on my 2013 BMW X3. Because I wanted to hide the wiring, I took out the two plastic bins on the sides in the rear to access the wiring and make the runs smooth. Everything went well - it was easier because the BMW has the battery in the rear, so no long run to the front for power. Everything necessary was included - handy to get the test light as well. Total times was almost 2 hours, but that was mostly doing the cosmetics to hide the wiring as well as the testing to find the right wires...Sahme on BMW for not selling their own wiring harness without buying a whole hitch for $700! 166698

Easy installation on the 2004 X3 3.0i. Very high quality kit. I simply followed the excellent video for the X3 also on this site at It installed just as explained and the adapter works perfectly. Tip: Make sure you have a good wire crimp tool like the one used in the video. Don't use pliers or the ones on the cheap flat stripper tool. You can get a set for about $10 at Lowe's or Home Depot. It will make all the difference. I am very happy with etrailer, great products, reasonable prices and great service. You can't go wrong. 68482

I have bought many products in the past hitches and harnesses. Stuff is right, never needs fabrication and is top quality material. I only wish they would add some extra solder less connectors so when you mess up you don't have to go to parts store. Harness kit comes with 12v tester great addition since I last ordered.

The Jetta Sportwagen (2010-2011 confirmed, may be other years) has modulating taillights. Other Curt adapters may work. Figuring out the signals with modulating lighting can be painful. This is what works for 2010-2011 Jetta Sportwagen: Driver's side: Gray / Black (pin 1): Tail Light Black / Red (pin 2): Brake Brown (pin 3): Ground Black / White (pin 4): Left Turn Black / Blue (pin 5): Reverse Passenger's side: Gray / Black (pin 1): Tail Light Black / Purple (pin 2): Brake Brown (pin 3): Ground Black / Green (pin 4): Right Turn Black / Blue (pin 5): Reverse 27373

by: Harry S.07/01/2013

Product was only a minor challenge to install on Lexus LS due to some difficulty in routing the power wire from the battery to the trunk. Found a rubber grommet under tail light that easily punctured and then sealed with silicone for the power wire. LED tail and brake wires on this car are very small - half the guage of the turn signal wires - so the quick clips took extra care to line up correctly. I have heard tales of the LED wires being cut completely thru by the splice, so care should be exercised to be sure the wiring is lined up properly. Otherwise, great product! 86943

Let me start off by saying that shipping through etrailer is excellent, everything that I've ever ordered through this company has been shipped within 15 minutes of when I placed the order, which Is outstanding. Also, the products that I've ordered have been defect free, and meet every standards that I had, and then some! The wiring for my 2001 Lincoln Town Car came with perfect instructions, and I got it installed by myself in under an hour. Thank you etrailer for having everything I need, having good work ethics, and excellent shipping! Don't ever change. (: 114742

My wiring in my 1998 mazda( ranger) b4000 could not handle all the new lights from my new tent camper so I went on line to find a converter that was powered straight from the battery and found kit 56146 which works perfectly now. All my lights work and installation was a snap, I encased the battery wire in flexible tubing for extra safety. Every thing else I needed was in the kit, thanks to a quick deliver I got to go camping on time for Grandsons spring break safely. This kit is fused at the battery and is very safe in case of shorts or overloads. Al 73418

The wiring took much longer than the install of the hitch (removal of trim to hide the power wire, debating where to route the wires & how to get them from inside the car to outside to the battery). The part about the stop signal (if using converter as powered for 2-wire system the red wire must be grounded) was a little confusing. I don't know if I was using it as a 2wire or 3 wire or 4 wire or 5 wires (there were 6 wires on vehicle side & 4 wires on the trailer side so was very confusing) took about 3hrs but could probably be done in half the time 152850

All I can say is WOW! I placed my order Sunday night and by 8 AM in the morning I had received 2 emails one telling me my order was being processed and would ship soon and the other telling me it had shipped already! Wednesday afternoon I receive an email telling me that my package had been delivered, they actually tracked the package to make sure it was delivered. I wasn't even home yet but I knew my package would be waiting for me when I did get home. I will definitely order from Etrailer again when I need more trailer related parts! 97462

Mounted this on a BMW X1 (2013). This kit is not vehicle specific. I had plenty of Power cable as the battery is rear mount, but hardly an inch to spare for any of the other wires. The instructions were pretty vauge and there is no vehicle specific information to help you find the correct wires, etc... It would be nice if etrailer provided custom instructions to specific vehicles as Crutchfiled does for stereo installations. However, I'm no newbie when it comes to wiring, so I managed to get a very functional and clean install of this kit. 60040

I received the package and contents in perfect condition. The shipping time was extremely fast. Due to below freezing temperatures, it may be Spring before I start installing the trailer lighting kit. I hope the wire clips are small enough to fit the tiny wires to the taillights and make a good connection. Disconnecting the battery to install the kit is a problem. A Honda will kill the stereo system when the battery is disconnected. This requires a trip to the dealer to get it unlocked. 167292

As mentioned in my review of the entire Rcvr and wiring process, no "plug & play" wiring harness yet exists for the Ford C-Max so you have to crimp into existing wires to make the connections. Found it better to wire into the driver's side harness and run the right turn signal wire over to the other side of the C-Max. The kit included everything I needed so installation was straight-forward. Def recommend the E-Trailer product line for users of any vehicles. You wont be disappointed. 110842

I installed this product in a 2013 Prius Plug-In. The install itself was fairly cumbersome, as there was a fair amount of disassembly required to access the necessary wiring. In the end, the product fit nicely and functioned perfectly. My only "complaint" was that the LED tester was so dim that it was very difficult to dicern on/off in the sunlight. 75995


Hi, Im installing this kit on 2013 prius two base, does anyone know how to check the tail light wire or its colors?Thanks a lot.

comment by: Valentin - 05/24/2014


I recommend using a circuit tester like the # 40376
Circuit Tester Kit

Ordered on a Friday and had it delivered and installed by Tuesday night. Now my V-Dub is an "SUV"!!! 23984


Was gonna do this on my 09 jetta wagen gasser 2.5L.How hard is it? Any thoughts on the gasser model towing?Had my eye on a quicklite 8.1. I thought it would be ok for weight.

The install is not too bad if you have done any basic electrical before. We have in fact shot a video fo the installation of this kit on a 2010 Jetta Wagen that should be pretty helpful for you, check the link below. The hitches available for the 2009 SportWagen have a 200 pound tongue weight capacity and a 2,000 pound trailer weight capacity. You should check the owners manual to see if it states a lesser capacity, if so, that is the figure you should abide by.

Installed this myself on my 2011 Jetta TDI SportWagen. The included instructions are not much help, but the videos here on etrailer tell you everything you need to know. Definitely watch them through a couple of times and expect that your install will take a little longer than when the pros do it. Not that hard. Works great once installed. Very nice that I can switch between trailers with incandescent and LED lights without worry. 94150

The trailer wiring kit for my Nissan Murano, with the circuit protected tail light unit worked flawlessly. The instructions were easy to follow and the installation went well. The only difficult part was the testing of the wires to determine tail light, brake light and right /left turn signals, which was very time consuming, cumbersome and required an additional person. I am very happy with the Curt trailer tail light wiring kit. 66182

Item was exactly as described and came with good, clear instructions. Everything that was needed was including with the kit. The circuit tester was incredibly helpful and easier to use than a multimeter. Customer Service with E-trailer is also really good. I needed to upgrade the shipping on my order. When I called, they were very responsive and got me taken care of quickly and the item showed up faster than expected. 161308

Mostly good - except the green wire to connect to the passenger side turn signal was too short for my Nissan Armada. Fortunately I was easily able to solve this with spare wire I had in the shop - but another 15 inches on the wire would have saved me the trouble. Also - the black wire to run to the battery was just barely long enough, thanks to the fuse wire. A bit more for future customers would be a good idea. 178492

I purchased the Curt wiring harness and it came with all the necessary parts and accessories. The instructions were generic making finding the specific wires a little difficult, but not a problem once I took the rear light out so I could find the brake light wire. Depending on the ability of the installer this could result in trouble. Details identifying the specific wires would have been nice. 77064

The kit was somewhat easy to install. The only problem with the kit is, the brown wire from the box goes to the orange wire and the red wire goes to the blue wire. Once I figured out that to do it became very easy. Great kit, as stated above the brown wire showes on your web site going to the blue and the reds wire going to the orange. Reverse the two and it works great. Thanks 129493

Perfect fit for my 2008 rabbit though the cross bar made contact with tail pipe. All I did to remedy the situation was to put a regular exhaust clamp (I believe it was a 2 1/2") around the last rubber exhaust hanger, as you tighten the clamp just keep an eye on the tail pipe as you eliminate the contact. Stop as soon as you get about 1/4-1/2 in. 127842

Product installed exactly as described. Seems to work perfectly on my Yakima trailer. Installation was done on a 2010 VW Jetta TDI sport wagon.

This is a good electrical design. Mounting may vary however. The 2011 VW Jetta has panels which must be removed so the adapter can be mounted. These are held on by plastic snap screws which may break if removed. Fishing the battery wire to the front can be challenging if you don't have the car on a lift. I persevered and it works great. 50721

Installing non-OEM wiring for towing is almost always a painful process. This kit, however, make it as painless as possible. I would have preferred better connectors then those blue (crimp in lock) devices shown in the picture but they do work. Just make sure you match up the wires as shown in the video and you will be fine. 162872

The kit was pretty straight forward to install. It was a little tricky getting access to the area in my GX470, where the wires were routed, but once in there it went well. The circuit tester/probe didn't work, so I had to use my multimeter to trace the wires. Once traced connecting the module to the vehicle lines was easy. 81077

  • What Does 200 Pound Tongue Weight Capacity Mean on the Trailer Hitch for a 2008 Mazda RX-8
  • Tongue weight capacity is the hitches capacity to handle the weight placed on a properly sized, rated and installed drawbar, when a trailer is attached. It also refers to the weight of items carried in the hitch receiver tube like a bike rack and bikes or a cargo carrier and the items placed on it, and the items loaded in the vehicle behind the rear axle. The CURT Trailer Hitch, # 11472, mounts to the bottom of the trunk pan and to the bottom of the frame rails using hardware that is...

  • The square tube Hidden Hitch # 60283 and Draw-Tite Hitch # 24866 are very similar, so similar that they share the same installation instructions.

Whereas, you would need to purchase those items separately if you went with the Draw-Tite. For that reason I would recommend you get # 60283.

  • Will Curt Trailer Wiring Harness, # 56146KIT, Work with LED and Incandescent Trailer Tail Lights
  • The Curt Trailer Wiring Harness, # 56146KIT, is a powered converter. This means that the trailer lights will be drawing most of the power they need from the battery. With this type of connection, the harness will work with LED and incandescent bulbs on the trailer. However, if you have LED lights and incandescent lights on the same circuit the lights may not function properly because they draw different amounts of power. It would be best to replace all the lights to one type or the other.
