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
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

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

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
The kit is fantastic and the harness installation video made things so Easy it was the simplest install I've ever done for about anything! Awesome info, support and products! Finding all the great info and How to videos on your site is what sold me to purchase from your company. You will Always be my first stop from now on!!!! Excellent !!! A++++ 132733

Installed on my 2008 Mercedes Benz M Class (ML350 4MATIC). Nice product with good instructions. This was my first install of this type of kit, so I was very careful in preparing for and doing the installation. It took about 2 hours with my son helping when I needed an extra hand. The next install would probably take less than 1 hour. Behind the access panel on the passenger side I found a large fuse panel with a conveniently located 12-volt positive source, so I used this instead of running the black wire and fuse holder to the battery (which is located under the front passenger seat in this model). The black power wire and green right-hand turn signal wire were run into the spare tire well from the driver's side, tucked neatly under the plastic trim on the back of the well, and into the passenger's side fender well. The 4-pole connector wire was run out by the driver's side access panel and simply laid across the rear of the cargo compartment when in use; when not in use it can be left in the cargo compartment or stowed behind the access panel. Works great! Thanks etrailer.com. 310840
etrailers delivery was much faster than I expected. because everything arrived so quickly I was able to get it installed professionally along with hitch in time for my wife and I to use our new camper for the long weekend when we thought we would only be in tents. very impressed with service and follow up emails regarding delivery. 222090

Install on 2011 VW Jetta Sportwagen TDI: Suggestions: 1) Have a helper, another set of preferably small hands, to help with holding wires and making splice connections at rear lights. The connections for VW are tight and don't have a lot of give; 2) Search/find video online that shows route (or suggests one) for running the power wire from back to engine compartment (this step isn't shown in most of the videos) 3) Be very frugal with the power wire run--I had just enough (within a couple inches) to make the run to the battery 4) And following advice of others: Start within the driver side light compartment and fish the power and passenger side wires out and to the other side rather than (as shown in most videos) starting in middle and outside and having to fish the transformer box behind the molding and up into the driver side compartment. It's going to end up there in the end, so why not just put it there and fish the other 2 wires out? 255084
by: Martijn S.05/10/2013
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
by: LEN L.07/16/2014
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
by: Steve W.08/27/2014
Product worked fine. The Right Rear turn signal lead wire was approx. 4' too short. FYI, for my 2013 Ford CMAX, the 12volt battery is in the rear, and not in the front of the vehicle. Therefore I didn't need all the Black Power wire that was provided. 148858

After some truly bad information and worse experiences with trailer wiring, I was delighted to work with your wiring harness. Nothing had to be trimmed or adjusted in any way. Everything fit together beautifully and to top it off, worked brilliantly the first time. Delivery was a bit ahead of schedule and the kit had everything needed to complete the job. Thank you! 220195
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

The wiring kit worked perfectly. Our tech was looking for one for our service van and mentioned he couldn't find one that was compatible to the Sprinter. I told him I would check etrailer.com and they had several choices. Same experience every time. I highly recommend etrailer.com. 139912
by: Shane K.12/08/2014
The wiring install was pretty easy of you are an electrician. I had my mechanic friend help me and we installed this kit in about 30 minutes. I recommend you have a professional if you have never done wiring before. 163617

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 installed this circuit isolating wiring module on my 2005 Mercedes ML500 this afternoon. I chose this module after watching the etrailer YouTube video of the installation in a 2003 ML350. For me the most time consuming part of the installation was routing the black power wire from the battery positive terminal to the module. I started at the battery, routed the wire across the engine bay at the top of the firewall and found it easier to route the wire down then back to the module. It took me a little longer because I didn't jack up the SUV. It's tight but there's room to safely route the wire up and out of harms way without lifting the vehicle. All in all I'd have to call this a very, very simple installation. 192280
Easy to install and works conveniently. If you need to operate a standard four wire trailer light system from a vehicle that uses the dual bulb, six wire system, this makes life easy! 104400
by: Steve G.05/25/2015
I would have preferred the ground wire to be a 4" longer to better locate the module. I fished the power wire up to the fuse box along the inside drivers side and used a spare slot. 196699

I had this installed on my 2013 prius plugin hybrid by uhaul. It works. Though your support personel told me that you do not have a kit for the plugin hybrid. That was confusing since i found this one with a very specific google search and ordered it. When i started to follow the video instructions, i quickly ran amuck, right after removing the rug. That is when i took it to uhaul. When i plugged it into the trailer the right running lights did not work. The problem was the trailer frame was not a good ground for the light. Ran a #12 gound wire from the front of the trailer to the light monting bracket and it now works. All's well that ends well. THOUGH I would have appreciated more help. 267358

On time with the right product. Not only that but they have a tutorial on utube describing how to install it. 128046
by: Jack A07/23/2016
I worked with a friend and followed the directions on the Youtube video. The first challenge was getting the panels off to get the connections for the light. Once I read the owners manual for the 2000 Volvo XC 70, it was straightforward. With one person working the turn signals, brake, and tail lights, and the other person inserting the tester probe in the connections, we were able to quickly locate the appropriate wires to tap. I would estimate 45-60 minutes for that part of the job. The most difficult part was getting a positive lead from the battery to the rear of the car. We spent the better part of 90 minutes trying to figure out where to run the wire. 275486

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 http://www.etrailer.com/Custom-Fit-Vehicle-Wiring/BMW/X3/2004/56146KIT.html?vehicleid=20049943. 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

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

terrific service 172673
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

Working just great, thank-you! 77399
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

The hitch was very easy to install on my 2017 Kia Sportage. I just loosened the tailpipe joint bolts to allow the muffler to come down some. The Kurt wiring kit was not like the ones in the Kurt videos of a 2015 Sportage. The kit I got didn't have the adapter that just plugs into the Kia's wiring. The cars wiring looked much too confusing and wires were different colors than expected so I ended up taking the car to a professional installer and paying $150 to have the wiring installed. The hitch was excellent and the wiring stuff OK. 286441

sorry that I can't show picture of wiring.I had it done at a service center due to a winter storm dumping 18" of snow on my driveway where I planned on doing the install myself.The delivery was fast and packed very nice.This wiring harness was installed in conjunction with a curt 2" 3500# receiver hitch.I plan on uing this not only for towing a trailer,but also a receiver style(curt)bike rack and a receiver style(foldable)tray that I will use to keep my vehicle clean.Will haul deer and garbage cans along with other unclean items. 160171
I bought this item so I could pull my tiny trailer behind my '98 Lexus. I had a small, local body shop install it. It has worked perfectly and the price for everything was reasonable. I was really impressed by the excellent customer service I was provided while I was searching for the right product, and they also took time to check in with me after one year to make sure I was still happy. Because of that kind gesture, I'm writing this to encourage others to buy items from this company! Tell George that Elaine W. sent you :) 262385
Kit was a snap to put in. 212842
Product works great on my 2004 Volvo XC70. Installation was easy and fast. Finding the wires was the only difficult part of the install. You have to prick the wire with the tester attached to ground and the wires are small. I stuck the point into my fingers several times before I used a tongue suppressor as a backup to the wire to protect my fingers. From then on it was easy. Having the module supplied with power directly from the battery inssures a bright light at the trailer. Everything I needed was in the kit. 263034

Wire kit is a necessity if you want lights and this kit is first rate, quality product. This is not a simple installation, You have to remove some interior trim pieces and route a hot wire through the firewall to the battery. Go through the rubber cable boot for the hood release cable. The wire will easily go through the same hole as the cable, small hands work best. This installation takes longer than the hitch, I took four hours and this was my second installation. Good product and necessary. 214827

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
