Installation

To determine where to splice into your vehicle's tail light wiring, you will need to consult the included instructions. Use the quick-splice connectors to attach the input wires of the tail light converter to the corresponding wires from your vehicle. Once you've spliced in the converter, connect the included hot lead to the black wire and run it up to your car battery. Connect the lead to the included fuse holder, and then connect the fuse holder to the positive terminal on your battery.


Then locate a flat surface inside your vehicle near the tail lights and adhere the black converter box using the provided double-sided tape. Find a raw metal surface to use as a ground point and secure the white ground wire using the provided ring terminal and screw. Finally, secure the converter wires to your vehicle using the included cable ties.


It is recommended that you use a small amount of grease on the 4-pole connector to help prevent corrosion.


Powered Tail Light Converter with Surface-Mount Technology

Because most trailers run on a 2-wire system - wherein the brake and turn signals are carried on 1 wire - the signals from your vehicle may have to be converted to be compatible with your trailer's wiring. If your vehicle operates on a 3-wire system, which means that it has separate brake and turn signals, then those signals will need to be combined so that they run on 1 wire to properly activate your trailer's tail lights. This converter will also ensure that your trailer's lights illuminate fully, even if your vehicle has pulse-width modulation (PWM) wiring. Note: This will not affect how the tail lights on your vehicle operate.


This converter is a circuit-protected, battery-powered unit that bypasses the electrical routes that are used by a basic wiring harness. As a result, there is virtually no draw on your tail light circuits.


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.

Great product and excellent instructions. The YouTube installation video was perfectly done and showed clearly every step. All of the parts supplied (with the exception of the continuity tester which was omitted) fit perfectly. The step by step power supply wiring was very helpful as it removed any doubt what was the best path to chase the wire to the battery. 508506

I used this on my 85 Toyota landcruiser. I had bought another brand at the local farm store and I finally gave up trying to get my lights working correctly. I’ve always had good luck with etrailer products, so I ordered this and ripped out the other box and wiring . Curt’s directions were great and this one was superior in every way to the other one. I now have perfectly working trailer lights. Thanks for a great product. I should have gone with this first and saved money and a lot of frustration. 539661

2009 bmw 528i. you almost can't see the trailer hitch below the bumper. I've NEVER seen a Beemer pulling a trailer............. Electrical hookup was just as the instructions said. BMW has the battery in the right side of the trunk so power hookup was easy. I put the pig-tail down in the spare tire well when not in use. Feel free to use whatever pics you see fit. Great product and install videos. 488584

2016 Mazda CX-9

The Curt Powered Tail Light Converter (w/ 4-Pole Flat Trailer Connector) is a critical component to a trailer hitch, and unfortunately the most finicky/tricky part of the installation for a DIY self-installer. However, after research and plenty of viewings of installation videos (including the one on eTrailer.com) it came together successfully. This product worked quite well. Most installations recommend running the main-power wire along the undercarriage to connect to the battery. However, in my installation on our 2016 Mazda CX9, upon inspection I found that route to be far too difficult (requiring the removal of a number of undercarriage/skid plastic panels, plus getting into the engine compartment was to be a huge challenge) - instead I found the easier/better option (which I used) was to stay inside the passenger compartment and run the wire along the floor behind door panels. It worked out quite well, and then access past the fire-wall into the engine compartment was accomplished using the same access-hole/rubber-boot that the factory used to bring all the OEM wiring in. All in all - the installation was successful this Curt wiring harness was well designed and we saved a significant amount of money by installing it ourselves. Thanks! 447338

The instructions for their universal wiring harness are very simple and easy to read, but finding the color diagram for the tail-lights on BMW 5-Series to match it up to took several hours. And I'm glad I did, otherwise I was about to really mess it up. (I was about to match color to same color, when my wife called in for dinner. Considering the BMW color schematic i would have ended up butchering those wires before I ever got it right.) 499246


Comments
The Curt wiring harness isnt a vehicle specific item that should be wired by function, not by color. Its recommended that a circuit tester like # 40376

be used to verify the function of each wire in the vehicles taillight wiring harness.

I have not finished installing this wiring yet. I don’t know how it’s supposed to wire up and will have to get professional help. It’s too much. Should have been color coated the same way as the wires in the car. 538844


Comments
The wiring harness you purchased isnt a vehicle-specific item, it would fit many different vehicles so therefore it wouldnt be possible to color code the wires as different vehicles use different wire colors. I do have a video showing a different wiring harness being installed on your vehicle. Simply use the provided link to view the video.The install procedure on your vehicle should be identical.

2004 Mercedes-Benz Sprinter

I installed it on a 2004 Sprinter van. Took some time but was not difficult. Both the wire to go to the right side and the one to go to the battery were short. But I was able to splice the right blinker in to the bundle that ran over there and knew the power wire to the front would be too short from other reviews. So far works great and I would buy again. I have installed a few hitches and wire hook ups that I have gotten from Etrailer.com Always have worked fine. 546840

The harness works well, and took a coupe of hours (and attempts) to install on my Golf R. It took over an hour to run the power wire to the battery through the interior/firewall. The rest of the basic install was a breeze. It was a bit more problematic for me, as I had installed the Euro tail lights (which have separate turn signals). The kit i bought could handle the 5-4 conversion, but I ran into a problem. Even though the car was re-coded for the lights and supplying 5 V to the running lights, both kits I tried would not trigger running lights on the 4-wire output. On the advice of a tech (thank you!), he mentioned that he had seen one other instance where it worked to use the license plate light as a source for the running light input. That worked perfectly, and ended up being a grey wire in the passenger side rear bundle. A little extra wire (and another TIGHT splice, and all was good. Thanks, again for all of your help! Your team really went above and beyond helping someone with a non-factory install. 543835

2013 Audi Q5

Pretty straight forward install on a 2013 Audi Q5 S-Line. There is an ground lug on the rear inside panel right next to a convenient spot to mount the unit. I removed the silver panel along the tailgate sill to route the power wire and the trailer plug tail before I started. It clips off easily, and you can reach between the side panel and the battery compartment with your fingers. There's a small electrical connector on the panel, so be careful to disconnect it before yanking on it. Make sure you replace this panel as soon as you have routed the wires, as that electrical connector is to two micro switches that detect if the door is closed... there is no power to the rear lights while the tailgate is up, so this panel needs to be in place before you start wiring. Correct wires were easy to locate. The 2013 Q5 is a little different to the wiring types listed in the instructions, as while the brake runs off the turn signals, there is a separate tail light wire. If you are probing for the wires, close the tailgate, and climb in through the rear passenger door. Here are the correct splices off the tan connector... Tail Light (Brown) - splice to Black with Green trace Left Signal (Yellow) - splice to Gray with Black Trace Right Signal (Green) - splice to Gray with Blue trace Red and White both Grounded together. The only issue I had was that the blue splice connectors supplied are too big for the fine wires on the Audi, so when I tested the install, I had nothing working. I replaced the blue connectors with the smaller red ones, and all worked perfectly then. Start to finish, about 90 minutes. 232589

After reviewing the instruction sheet and understanding that I needed to run a power wire from the unit to the battery. I decided to let my Saab mechanic to do the installation. I figured that the time it would take me to route the power wire to the battery would take hours and that my Saab mechanic could do this within an hour because he knows that car better. 518074

2018 Volkswagen Tiguan

The installation instructions are straight forward. Installing on my 2018 Tiguan was a bit of a pain in the butt as VW gives you little to no slack on the tail light harness to work with. Literally maybe 2 inches of slack if that! Also you have to run the 12V battery wire under the vehicle as there is nowhere to get thru the firewall so running the wire inside the vehicle is not possible. There was however plenty of wire supplied for the 12V supply to get the install completed. Also the Tiguan has a windage tray the length of the vehicle so as long as you secure the wire away from any moving parts its well protected. My only complaint with the product, (And this is nit picking a little), was the green wire that supports the right taillight, Blinker/stop light was a bit short. It would have been nice to have maybe 4 more inches to work with. As it was, I had no slack on the Tiguan harness and this just made it more of a pain in the butt to install. There was enough wire to get from the left side of the vehicle to the right side but just enough and a little more slack would have made it easier. My install difficulties with the Tiguan is no fault of the product but other then the green wire being a little short the product works as advertised. Again installation is straight forward and difficulties running the wire thru the vehicle is no fault of the product! I gave it 5 stars as it does work well. 444853
