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

This is a fantastic product. It save me $120.00 to have a special wiring harness installed on my Mercedes M 350 to enable the LED lights of a U-Haul trailer. Just plug it into the Mercedes factory installed trailer light socket and it provides the proper resistance for the system to read and light the LED trailer lights. 57068

etrailer provided a level of service that I have not seen in a company since gas station employees used to run out, pump your gas, wash your windows and check your oil. Seriously, this company could be a case study in the harvard business school review. They could run a secondary business teaching other companies how to provide the best customer service on the planet. Well done etrailer!!

The adapter I ordered was exactly what I needed. The best part was the customer service from etrailer.com. You don't see the kind of attention placed on big orders from other suppliers as was placed on this single adapter. Very satisfied and will tell anyone looking for a great supplier this is the place. 115825

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

Used on my 2008 BMW X5 and trailer with LED lights. Before I used this, my BMW didn't even recognize the trailer and power the lights at all. Using this device, the BMW's computer still "thought" only the running lights were burned out and had a little triangle warning on the dash, but everything worked just fine. Turn signals flashed at a regular rate.49985

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". In other words......It Don't Work!!!99913

Comments

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.

Something like PK12716 should fit the bill just fine.

  • Trailer Turn Signals Only Work if Running Lights and Brake Lights are On, 2007 Nissan Quest
  • This could be a ground problem. A bad ground connection can cause all sorts of problems. First check the trailer connectors on the vehicle and on the trailer for any dirt or corrosion and clean them out. Corrosion can also build up behind the connectors where the wires attach. On the vehicle side, make sure that the main ground is attached to a clean bare metal surface on the frame. On the trailer side connector, again make sure that the main ground is attached to a clean metal surface. Us

  • 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.

  • 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

  • You are correct about the bulb out sensor and the adapter # TR20141. There are load resistors built into the adapter to provide more load so that you do not get that sensor. The solenoid should have enough draw without it but it might help. Since it works as it should when connecting the trailer to another vehicle that does sound like and issue on the vehicle side or with the adpater.

  • First an adapter with load resistors that goes from a 4-Way flat to a 4-Way flat is not available. You would need to use the 7-Way to 4-Way adapter, # TR20141 for that. This particular adapter was designed to offer enough resistance when towing a trailer with LED lights so you no longer get those errors. The other option is to install load resistors, like # P230004A-2 for a 2-pack, in line on the trailer wiring for each circuit.

The load resistors will need to go on each circuit so you will need at least 3 for a 4-Way trailer connector for the basic lighting functions. These will provide more draw on the system and the vehicle will not think there is a bulb out. The other possibility is that there actually is a bulb ou

The 5-Way will also have a reverse light function if that circuit is functional on the 7-Way.

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.

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.
