Tow Ready Trailer Wiring - 20142
- Wiring Adapters
- Single-Function Adapter
- 7 Round - Blade
- Plug Only
- 7 Round - Blade
- Tow Ready
Designed for use with vehicles that have lamp-out sensors, this adapter ensures that your trailer with LED lights does not trigger any warnings or hyperflashing when hooked up to your vehicle's 7-way, blade-style connector.
Features:
- Bypasses your vehicle's lamp-out sensor so that you can tow a trailer with LED lights
- Prevents your vehicle's computer from sensing that a trailer light is burned out, which is how it would normally read the LED lights on the trailer
- Designed for use with vehicles with Lamp-Out sensors - such as Audi, Mercedes-Benz, Volkswagen, and Porsche
- Plugs into the 7-way, RV-style trailer connector on your vehicle
- Provides a new 7-way, RV-style trailer connector that works with trailers that have LED lights
If you have a vehicle with a factory tow package that has a lamp-out sensor and you tow a trailer that has LED lights on it, then you've likely experienced hyperflashing and/or false computer errors. Because LEDs pull such a small amount of power, certain sensors are unable to detect them. The result is a warning in your vehicle that continuously tells you that the trailer lights are not functioning. In addition, the lights on your trailer may not illuminate properly because of your vehicle's inability to recognize LED lights. This can lead to either hyperflashing lights on the trailer or lights that will not illuminate at all.
This adapter has a built-in bypass system that is designed to eliminate these problems. Just plug the adapter into your vehicle's 7-way, RV-style trailer connector and you're good to go. Plug the wiring connector from your LED-lit trailer into the adapter's 7-way, blade-style receptacle and the trailer's lights will illuminate as they're supposed to, without triggering errors in your car's computer.

When I changed my vehicule for the Expedition 2021, I was getting the error message "trailer left turn lamp fault" when towing my RV. After searching online I found out that there wasn't really a problem with the car or the RV. The source of the problem was that I was using the Ford factory tow package with brake control and that their computer thought there was a faulty bulb when in fact it's just because of the low amperage used by the LED lights.
This problem can happen with different vendors not just FORD.
I was releived that there was an adapter to fix this but it was backorder EVERYWHERE.
etrailer kept me informed for several weeks/months until the part was finaly available. (thank you guys for that by the way)
With this adapter, my problem is no more and I can safely travel with my RV without having my left lights disabled by the car's computer (yeah it did that).
Every RV shop should have that and know about this possible issue.
Buy yours before they go BO again. :)

When my 4-pin trailer light plug was plugged into my Jeep Grand Cherokee (GC)'s 4-pin connector, the GC reported (on the dash and via a highly annoying beep every time I hit the brakes!) that the LED trailer lights were out, presumably because LED lights don't draw enough current (don't have enough resistance). When using this adaptor that plugs into the GC's 7-pin connector and adapts to my 4-pin plug, problem solved! (I had plugged into another trailer that had incandescent lights, and I didn't have a problem. So I can use this adaptor when I'm pulling a trailer with LED lights, and not use it when I'm pulling one with incandescent lights...perfect!)

I am an amateur Porsche Race Car Driver and have a trailer that I pull my race car on. I pull my race car with a Porsche Cayenne Turbo S. I could never get the lights to work properly and hated to rewire as I use an american truck sometimes. Before installing the adapter, the lights would just blink and had no brake lights or signal lights.. The adapter I bought is a great solution for European cars and/or trucks. I purchased the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass - 7-Way RV to 7-Way RV - Vehicle End and it works perfectly. The blinkers works. The brake lights work. I can't believe such an inexpensive solution solved my problem. Contact e-trailer before you think of rewiring any trailer.

Solid, Well-Made, Does Exactly What It Should.
HyperFlashing is Not Cool!!!
I've been trying to track down a part which solves this problem for a while. I started using an LED-equipped trailer and the hyperflashing & computer warning messages are annoying! I almost settled for 20141, but glad I waited. Also, most retailers aren't receiving this part for another month or more. eTrailer shipped the same day as my order.
NOTE: This works well with Range Rover also.
Not related to the product: This was my first eTrailer order and I was VERY impressed. I spoke with two ladies regarding this part and eTrailer's customer service is TOP NOTCH. I will definitely order again in the future! THANKS!

what year range rover does this work with. I just tried it on my 2008 LR3 and I still have the problem?

It should work independent of year. Check your trailer connector and make sure the connections inside have not corroded for starters. Also check all the grounds of the trailer wiring and if applicable on the vehicle trailer connector. Ground issues cause most of the electrical gremlins in the trailer world. On 7-Way systems, corrosion inside the connector is another likely culprit.
by: Steve 04/01/2023
This connector adapter solved an irritating problem in our 2022 Thor DELANO Sprinter with notifications coming from the tow car about the lights. We also have a Nighthawk tow bar with lcd lights and the tow vehicle also uses some lcd lighting. These conditions created a situation where the turn signal was really sped up, and I had to dismiss several lighting notifications/warnings every time we started up the RV. No more! I will also add that the item shipped immediately after ordering, and it arrived several days earlier than expected.

I was on my way to pick up new RV when I learned I need an adaptor for the trailer lights to work with my pull vehicle. I called Joshua at etrailer and he took care of me quickly and got me the adaptor fast. Outstanding customer service. etrailer earned a new client for like.
by: Tom 10/21/2022
There was a delay in getting this product due to back order. I was kept informed of it’s expected delivery. When I did get this item it worked perfectly in making the truck thinking it was hooked on to a trailer and therefore would allow the side cameras to work when activating the turn signal . Most satisfied with the product.
by: Robert 08/17/2022
I bought this because I tow trailers with LED lights and I was concerned it would be a problem with a new car. Turns out the new car (2022 Volvo XC60T8) works with LED trailer lights so I don't need this for that situation. But I anticipate using an RF brake controller and I may need it at that point.
by: Dr. X05/10/2023
Thanks Gregory! He answered my question not only fast and accurately, but even gave me a part number (which I ordered right away). Already received the part and it works perfectly. It pays to work with the experts! Thanks!
by: Stacy04/25/2022
Intermittent connections! Thought the car was charging the camper battery while driving, arrived at camp with a dead battery. Other connection intermittent as well; sometimes car indicted trailer lamps were bad. Sometimes I could see the trailer lamps flicker while driving. Do you sell a more reliable solution?

I have contacted the manufacturer and they have confirmed that this product is not able to perform for charging the battery of your camper while driving. This part is a pass-through connector that will provide what the vehicle is capable of. All it does is provide a little extra load on the lighting circuits, it does not modify the connections. As for your lights flickering while driving, I suggest checking some of those connections to make sure that there are no loose connections. I would also suggest making sure that all of the connections are good and not corroded.

Easy to order, arrived quickly and works like it's supposed to. Can't ask for much more.
by: Bruce C10/10/2019
This adapter saved our sanity! Our 2019 F350 kept giving us the ‘trailer disconnected’ warning constantly while pulling our fifth wheel. We researched the problem online and realized that our truck wasn’t sensing the led lights due to their low voltage. Took the truck to the dealer who assured me they could fix it however the first time we took it out and I adjusted the trailer brakes I started getting the message again . So tried finding an adapter to bypass the bulb out sensor on the truck. I found this via a google search . Plugged this in, and no issues since!! It is awesome and such a good price! I would recommend this to anyone who is towing a trailer with led lights with a Ford truck.

My tow vehicle is a Mercedes 2006 ML500 that had issues connecting with the improved LED lighting on my Airstream trailer. I had a choice of a $800 wiring upgrade or this; I tried this and couldn't be happier. Highly recommend to solve the problem - works well, sits in glove box, has held up to frequent use. Only comment - you have to be more firm when you insert It into the receptor - not a big deal, but a thought if you're having problems connecting. Great product, customer service - this company provides practical and reasonable solutions. I'm a committed customer.

I bought this to try to override the glitch in my 2019 GMC 1500 Denali that would not allow the Furrion RV camera to connect. Some on Forums claimed that this was the fix... It didn’t solve the issue. Thankfully that issue went away when I traded for a 2020 Denali HD 2500. Nothing wrong with the product, it just wasn’t the elusive silver bullet I needed.

Got my LED trailer lights work in on my Audi! I had a small issue with the spring hinge, which broke on the first unit. E-trailer was outstanding and promptly sent me a new one with a return authorization for the old one. The new one works perfectly, and I would definitely order from E-trailer again! Excellent customer service, and they promptly addressed my minor issue with the first product.

These were on backorder everywhere when I ordered these and asked them to let me know when they had them in stock. They did just as I had asked and i got my product soon after!
by: Mike S07/21/2017
Bought this to use on a 2017 Ford F350 that was having trouble with trailer turn signal fault and trailer disconnected message would also come up on the dash. Finally figured out it was the LED lights on the trailer that were causing trouble with the trailer system on the truck. This adapter works great for that , even though it doesn't list it as working with a Ford. Very good product and very good service!

Thanks for the Review Mike. I did reach out to my friends at Tow-Ready and confirmed that this item is not exclusively for the European vehicles, and will work with any vehicle that has a trailer lamp out detection monitoring system. The European models were leading the way with those electrical systems. Also if you happen to need a 7 to 4-way adapter the # TR20141 functions the same way. It just provides a 4-way for the trailer connector.

Great so far -- bought this to connect a Mercedes ML350 suv to a Flagstaff travel trailer. As is mentioned many times in different trailering forums, some European vehicles have an issue with false sensor readings when connected to a trailer with LEDs. I had the same exact issue and this adapter seems to have fixed the problem perfectly. Time will tell as we go on our first big road trip with the travel trailer next week. But for now, looks like a winner.

Adapt or works fine. Using it on a Mercedes ml350. However, we bought it ruse with a Curt Bluetooth brake controller which is a piece of junk so we don’t really use the adaptor any longer at this point.
by: Jim B.12/31/2015
This is just what I needed for my 2011 BMW X5d, which has LED taillights, and my new trailer also with LED lights. All trailer lights work and no warning messages on the X5. Thanks etrailer.

- Recommended Adapter For 2009 Volvo XC90 To Tow 2017 Airstream Sport 22 With LED LightsWe have an adapter that may take care of the problem with LED lights on your new Airstream. I recommend using the Tow Ready Trailer Connector Adapter, part # 20142. This adapter bypasses the vehicle lamp-out sensor so you can tow a trailer with LED lights. This adapter simply plugs into the 7-way on your Volvo and you plug your trailer connector from the trailer into it.
view full answer... - Troubleshooting the Tenkosha Prodigy RF Brake Controller on 2014 VW TouaregYour 2014 VW Touareg has lamp-out sensors which can cause problems when trying to install the Prodigy RF 90250. Using the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass # 20142 should remedy the problem because it will increase the draw on the system which won't result in an error being shown on your Touareg.
view full answer... - Can Lamp-Out Sensor Trailer Connector Adapter be Used on a Ford F-150 Towing a Trailer with LEDsWe've had customers use the lamp-out sensor trailer adapter, part # 20142, with Fords and it's worked great for them. The page mentions Audi, Mercedes-Benz, Volkswagen, and Porsche but those are just examples of vehicles that are known for having the lamp-out sensors. The # 20142 isn't actually vehicle specific and will work on your F-150.
view full answer... - Adapter to Prevent Bulb Out Error Code of 2021 Ford F-150 Towing Trailer with LED TaillightsFor your 2021 Ford F-150 that is showing a lamp out error code when you connect a trailer with LED trailer taillights the correct adapter to fix the issue would be the part # 20142 that you referenced. This will put enough load on the trailer wiring to allow the truck to stop thinking that a bulb went out.
view full answer... - Adapter to Allow 2019 Mercedes GLS450 to Tow Trailer with LED TaillightsNewer European vehicles like your 2019 Mercedes GLS450 notoriously don't like trailers with LED taillights. For these situations the solution is the 7-way adapter part # 20142 which has diodes built into it so that the vehicle thinks a trailer with standard lights is being used.
view full answer... - Solution To Allow 12 Volt Accessory Circuit to be Active on 2019 Mercedes SprinterThe 7-way to 7-way lamp out adapter # 20142 would work for your 2019 Mercedes Sprinter to prevent the sensor issue you are experiencing. We've had customers with Sprinter vans like yours and they reported that this fixed the issue.
view full answer... - Does a 2018 Chev Silverado 2500HD Have Lamp Out Sensors The 2018 Chevy Silverado 2500 models do have the lamp out sensors as do more and more American made vehicles as they get more computerized. Whether your specific trailer will trigger the sensor or not is unknown as they do vary. If you find you have an issue, then I recommend the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass - 7-Way RV to 7-Way RV - Vehicle End # 20142 which has load resistors to allow the trailer to function well without the vehicle having that lamp out error.

Some vehicles are more picky about ground connections than others, which would explain why the boat trailer is working well with your older truck but not your 2021 Sierra. The most likely trouble spot is the main ground where the trailer connector grounds to the trailer frame. This can usually be found on the trailer tongue, simply trace the white ground wire from the trailer connector to locate...
view full answer... - Why Would Trailer Wiring of Boat HyperFlash After Getting SubmergedWater and electronics don't generally mix well so what you are experiencing would be related to something getting wet and causing odd behavior from your trailer wiring. The # 20142 would not fix your issue. Best option would be to go over the wiring of the trailer wiring looking for any exposed sections and insulating as needed. You should also verify if you can whether or not your trailer lights are submersible. I attached a link to all of the submersible trailer lights we offer as well.
view full answer... - Using Tow Ready # 20142 Adapter to Fool Bulb Out Sensor in RV While Pulling Tow Dolly w/ LED LampsIf the sensor lamp you're seeing displayed is indicating that you have a trailer taillight bulb out, the Tow Ready # 20142 will indeed work. Since LED's draw a tiny fraction of the power that incandescent bulbs do, a vehicle with a bulb out sensor will think that you have a burned out bulb. The # 20142 has a load resistor in it that fools the sensor into thinking that more power is being drawn through the circuit. If you'd care to view a product description video featuring the # 20142,...
view full answer... - Will Wiring Adapter # 20142 Prevent Hyperflashing of Taillights on Cargo Carrier of MB SprinterYes, the part # 20142 has load resistors built into them to allow them to prevent hyper-flashing that is caused by LED trailer lights. Or in your case cargo carrier lights.
view full answer... - Does the Lamp Out Bypass adapter part # 20142 Use Resistors to Prevent Lamp Out ErrorThe Lamp Out Bypass adapter part # 20142 that you referenced basically just has resistors in it to simulate the load of incandescent bulbs to prevent the lamp out error. It could be that the resistors you installed on your trailer have enough resistance to get the lights to function properly but not get rid of the error message.
view full answer... - Tow Ready Lamp Out Adapter Recommendation for a 2012 Mercedes Towing LED Light TrailerYes, the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass # 20142 that you referenced is designed to do exactly what you are needing. This connector is designed to let foreign vehicles with lamp-out warnings tow trailers with LED lights. You would want to plug this into the 7-way on your vehicle.

What is happening in your situation is just a weak ground on your trailer.

You have a good enough ground to operate just the running lights or just the the blinkers but when you try to do them both at...
view full answer... - How To Improve Voltage On 7-Way Trailer Connector for a Mercedes Benz GLS550Yes, the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass part # 20142 will help you receive a full/constant 12 volt signal from the trailer connector pins on your Mercedes Benz GLS550. The device has built-in load resistors that work to bring the correct voltage up to the pins on the trailer connector. The low/varying voltage is common on German vehicles such as Audi, Porsche, BMW, and Mercedes.
view full answer... - Will Sensor Prevent Warning If Light Is Out Using The Trailer Connector Adapter # 20142Yes, The Trailer Connector Adapter w/ Lamp-Out Sensor Bypass # 20142 will still display the lamp of message is lamp is out. The adapter is designed for vehicles with lamp out sensors such as Audi, Mercedes-Benz, Volkswagen, and Porsche. This adapter plugs into the 7-way, RV-style trailer connector on your vehicle. This adapter also provides a new 7-way, RV-style trailer connector that works with trailers that have LED lights. I attached a review video link below.

You will want the Trailer Connector Adapter w/ Lamp-Out Sensor Bypass - 7-Way RV to 7-Way RV - Vehicle End # 20142 which has the load resistors inside to help with exactly what you stated.
