This resolved my issues with my 2007 BMW X5 3.0si. My trailer LED lights had just been blinking whenever the 4-pin flat plug was plugged into the round BMW adapter. The brake and turn signal lights still worked, but when nothing else was going on, or even when the lights were turned off, all the trailer lights just flashed constantly. When I first plugged this in, the lights did the same thing. I unplugged it, reseated the 4-pin flat plug, then reseated the round adapter, and the trailer lights were still flashing. I turned on the car lights and tried the brake and signal lights. Trailer lights still flashing. I turned the headlights off, and the trailer lights went off! Brake lights and turn signals worked, and no flashing lights! Turned the headlights back on, clearance lights and tail lamps worked and no flashing! Brake lights and turn signals worked and no flashing! Cycled through everything a couple of times, and all was good - guess it just needed to get used to everything, but now it is working great! This $15 piece saved a $4,000 investment, so I'm quite happy! It also showed up a day faster than expected, which made it even better. Pat was a very big help getting it selected and getting it here faster! 126557

From the start I have had issues with trailer lights on my Porsche Cayenne Turbo and whatever product I tried, it did not fix the problem. The plugs I ordered from www.Etrailer.com plugged right in and fixed the problem between the LED trailer lighting and my Porsche. I hear it is a common issue on German vehicles, so I highly recommend this product to anyone. I couldn't be happier with the product itself AND the customer service from the staff all the way from the order, to confirming delivery. Thanks again! Attached are a few pictures of the towing setup! 102018

I have a 2012 Navion RV (Sprinter chassis, Mercedes drive train). Becuse the trailer wiring feeds into a dedicated module, it is not possible to connect a trailer with LED lights. The lights on the trailer will not work because the LEDs do not demand enough power to trigger the regulator on the module. I ordered the TR 20141from e-trailer. It converts from a 5 or 6 flat to a 7 round. Built into this plug are resistors that increase the demand on the module as would incandescent lights on a trailer. The TR 20141 solved the problem. It is well made, easy to wire and is reasonably priced. Very satisfied with delivery too. No fear with e-trailer. 141757

Beware the dimwits at U-Haul as they have NO CLUE what they are doing. eTrailer.Com has this priced at HALF what U-Haul charges, and they don't even know Mercedes cars need them! 137343

I have a 2001 BMW E53 X5 with the factory tow package. It has a 7 blade round connecotr, however my tailer for the jetski and jet boat both have the 4 flat connector. None of the trailers have LED at the moment and I doubt that I will ever convert them to LED. I need an adapter connector so that I can connect the trailer lights to the BMW connector.

On my Touareg (2004 model) with a trailer with LED lights hooked up, I would get "CHECK LIGHTS" flashing on the dash and an annoying DING! from the dash every 15 seconds. That's enough to drive you mad! A Cayenne or Audi Q7 would do the same, fyi. After researching online, this seemed to be the adapter I needed to add the right resistance to prevent the warning from appearing, and it worked! No more warning, no more annoying chime. And the price was great too. Thumbs up! 115646

Shipment was fast. Received in just under a week from when I ordered! Adaptor corrected my flashing parking lamp problem and everything now works as it should. Only issue was is that I was unable to use the tracking feature on the website to see where my package was or when it would arrive...since I received it pretty quickly, that was really not that big a deal but probably something that could be improved....I would definitely do business here again!!! 114536

This plug was purchased for my 2010 Porsche Cayenne S and works perfectly with my boat trailer that has LED lights. I originally had a more generic plug and the LED lights on the trailer seemed way too bright. I would also get a momentary warning about the lights system when starting the car. Now that I have this specific plug, I no longer get the warnings and the trailer lights operate at the proper intensity. Exactly what I needed for my set-up! 98630

I called and asked if this would work for an '06 Range Rover Sport SC. "Oh, sure." was the response. First of all it doesn't even fit through the opening in the bumper. However I was so desperate for a solution to the "flashing" problem, I partially removed the bumper cover so I could insert the plug. Sadly.......It doesn't stop the "flashing".

  • Trailer Lights Not Working with 7- to 4-Way Adapter on a 2012 Volkswagen Tiguan
  • It sounds like you are using a 7 to 4-Way adapter in the factory trailer connector on your 2012 VW Tiguan. If the trailer has LED tail lights, you will need a special adapter, # TR20141. This adapter should allow the trailer lights to function properly.

  • Will Tow Ready Wiring Adapter # TR20141 Work With Trailers Using LED or Incandescent Lighting
  • The Tow Ready Trailer Wiring Adapter, part # TR20141, you have referenced will work with both incandescent or LED lights on a trailer. This adapter is designed to be used on vehicles with incandescent lights towing a trailer with LED lights. The Lamp Out Warning Module on your BMW X3 is a feature that lets you know of a bulb that is burned out on your vehicle. It also passes through the trailer wiring. When towing with a trailer that has LED lights, which require less power then incandescent...

  • Towing Trailer With LED Lamps with 2012 VW Tiguan
  • Since you already have the 7-way trailer connector, all you will need is the Tow Ready adapter, part # TR20141. This adapter uses an internal load resistor that will prevent the bulb out sensor from triggering. Without the LED adapter, the very low power draw from the LED trailer lamps will make the bulb out sensor think there is a burned out trailer lamp bulb. Simply plug the adapter into your existing 7-way, and then plug the 4-pole on your trailer into the adapter. There is no...

  • Will 7-Way to 5-and 4-Way Trailer Adapter TR20141 Fix Flashing Trailer Lights, 2010 Mercedes GL450
  • If the trailer has LED lights and you are having issues with them not working then you would need to use adapter # TR20141. To plug in a 4-Way, you would just not use the last opening on the adapter. That would be for a 5-Way flat (it works with both 4-Way and 5-Way flat connectors). In the event that the 4-Way on the trailer is not conducive to this design because of a rubber or plastic covering, you may have to trim it or replace the 4-Way end with a compatible one like # 18004.

  • Turn Signal Hyperflash on Tow Vehicle Towing a Boat Trailer
  • It sounds like you have experienced a hyperflash condition. LED lights will flash like that because they do not provide enough power draw for the system to recognize them. Also, you should not mix LED and incandescent lights on a trailer. If the vehicle has LED lights and the trailer has incandescent lights then as long as the vehicle has the proper converter installed or has the factory wiring harness it should be fine unless it is the factory harness on a German vehicle like a BMW...

  • If your Cayenne has the 7-way connector, you will simply need an adapter to convert it to a 4-pole. Because your Cayenne is equipped with a bulb-out sensor, if your trailer has LED lamps you will need to use an adapter with a resistor in it like part # TR20141. LED lamps draw very little power, and fool the bulb-out sensor into thinking a bulb is burned out. This will make the turn signals hyper-flash. If your trailer uses incandescent lamps, you can use any of the other 7-way to 4-pole...

These adapters have load resistors in them that provide additional power draw so the vehicle thinks there are incandescent lights on the trailer.

The LED trailer lights do not offer enough draw on the system for the lights to work. On a lot of these vehicles you will also get a bulb-out warning in the vehicle. The solution is to use an adapter that has load resistors in it, # TR20141, to provide enough draw so the lights will work and so you will not get that bulb-out warning. The adapter will go from a 7-Way...

  • Will Round Tube Stainless Steel Trailer Hitch Receiver Step with LED Lights Fit a 2003 BMW X5
  • Provided your 2003 BMW X5 has a 2 inch trailer hitch receiver opening and a 4-Way trailer connector then the Pilot receiver step with LED lights # CR-600LED will fit. On some German vehicles like BMWs, when an accessory with LED lights is used it can cause a bulb out error in the vehicle. To fix this, if your X5 has a 7-Way trailer connector, you would need to use # TR20141. It plugs into the 7-Way and then the step will plug into the 4-Way end and eliminate the bulb out error. The...

  • 7-way Recommendation for a Pre-Wired 2014 VW Tiguan R Towing Trailer with LED Lights
  • First off, thank you very much for including the picture that you did. With that picture I know exactly what connector you would need. What you have is the industry standard plug that a standard 7-way would plug into. You would want the Replacement Multi-Tow 7-Way # 30955. The connector end of this would plug right into the connector of your picture and you would have a fully functional 4 and 7-way. Since your trailer has a LED lights and a 4-way you would want the 7-Way to 5-Way...

  • Compatibility of Tow Ready 7-way to 5-pole Adapter # A75TB with 2103 Toyota 4Runner
  • The Tow Ready 7-way to 5-pole adapter that you mentioned, part # A75TB is not a vehicle specific item. As long as the 7-way on your 4Runner is fully functional, in most cases the adapter will work just fine for you. If your 4Runner has a bulb out sensor that warns you when you have a burned out taillight, and you are towing a trailer that uses LED taillights, you will need to use an adapter that has a load resistor installed in it, like part # TR20141. Either adapter can also be...

  • Will Tow Ready 7 to 5-way Adapter for German Cars and LED Trailers Support Reverse Light Circuit
  • If you used the Tow Ready 7-Way to 5 or 4-way # TR20141 that you referenced with a trailer that has a 5-way then yes, the reverse light circuit will be active. If you used it with a 4-way then no it would not. That fifth circuit is for reverse lights. There would be no noticeable load or drain on the vehicles electrical system from the wiring of this adapter either. If you needed just a 7-way adapter that will work on the German cars that are sensitive to the LED trailer lights you...

  • Reverse Electric Lockout Solenoid Not Working using 7 to 4-Way Adapter on 2006 Porsche Cayenne S
  • It is possible that the solenoid on the trailer is not drawing enough power for the factory trailer connector on your 2006 Porsche Cayenne S. But first, you will want to test the reverse circuit on the vehicle connector to make sure it is working. You will need to chock the wheels of the vehicle, apply the emergency brake, and have someone sit in the vehicle with their foot on the brake while they start the vehicle and place it in reverse. Then you will use a circuit tester such as...

  • Oval LED Brake Light Shuts Off Active Blind Spot Assist on my 2014 Mercedes-Benz
  • When you plug anything into the 4 way connector on the back of your 2014 Mercedes-Benz, the vehicle can not determine what is connected so it assumes it is a trailer. If a trailer was connected, the Active Blind Spot Assist could go off continuously if it sensed the trailer on the back of your vehicle. This is why your system deactivates when you plug in the Adapter, # TR20141, and Oval LED Brake Light, # CR-017. It is strictly a personal preference as to whether the Active Blind Spot...

  • 7-Way to 4-Way Adapter Recommendation for a 2013 Audi Q7
