Hello neighbors. It's Brad here at etrailer. And today we're taking a look at the cut seven to four and five pole adapter. So as the name implies you are able to adapt a factory seven way to a four and five pole. And that's really nice because a lot of vehicles will have the factory seven way on there but maybe not the four pole. So if you look came to hook up to a trailer and realize that they have a four or five pole, you might be out of luck or have to run additional wire to permanently mount it.
Well, that's where this comes into play. So that's gonna allow you to be able to have your seven way, your four pole, as well as your five pole just with plugging into the factory seven lane. Now, sometimes your towing vehicle will not recognize the LED lamps on your trailer. And that's where this is great too as plugging that in is gonna allow this to send that signal to your vehicle making sure that your lights are actually working with your signals. So like our neighbor here they have a trailer with a four pole but they got a new vehicle that has a seven way.
So instead of having to run all new wiring for it you can simply plug this into the factory seven way. You can take your four pole and plug it in or if you have the same vehicle but you're towing a different trailer. This gives you that same ability. So having this is going to allow you to hook up electrically to those trailers. So now let's go ahead and test it.
So first I'm gonna start with my running lights. Next I'm gonna do my left turn signal, my right turn signal. And then finally my brakes. Now this neighbor also toes, a boat trailer. So having the five pole is gonna be really nice for the surge lockout as well as reverse light.
Now, for some of your foreign vehicles or high end vehicles that have LED taillights sometimes they don't have enough power to power the trailer lights. Well, this is gonna help with that. Allowing that to give it enough juice to be able to still retain your lights on the trailer. Something that's really nice about this is the size and that if you normally tow a seven pole you can simply swap this in whenever you're picking up a different trailer and need to hook up or really you can use this to hook up to any trailer. You have that ability and you can keep this in your glove compartment until you need it. And that was a look at the cur seven, two, four and five way adapter..

Curt 7-way connector to 4-way or 5-way flat connector is designed for use on vehicles with Trailer Lamp-Out sensors when towing a trailer equipped with LED lights.Used on a 2012 Mercedes-Benz Sprinter, Factory tow package with a Kuat piston pro x bike rack. Totally makes the brake, turn signals, running lights work on the rack.
EXACTLY what I needed. My problem was we need the lamp on the lifted license plate on our mobility ramp and that constantly causes the lamp outs on Kia 2024 Telluride to alarm. After applying the plug, no more warnings! Thank goodness! What an obnoxious feature!
This is an essential item for towing my LED equipped trailer with my 2023 Volvo. Without it my car does not recognize the trailer being connected and does not go into towing mode.
C35FR solved the issue with my 2016 F150 not recognizing Hollywood Racks Light Bar.((Etrailer part HLY54RR). The light works as designed with this adapter.
This adapter is perfect for enabling LED trailer lights for use with an older vehicle that uses incandescent lights. In my case, I use a 2004 Sprinter as a tow vehicle, and without this adapter, I had no brake lights, turn signals, or flashers on a Wells Cargo trailer built in 2014. With the adapter, all trailer lights work! Other solutions exist to fix this problem, including external resisters that provide sufficient load to trigger the lights, but this adapter is the perfect simple fix.
Incredible service by e-Trailer and specifically by Emily who answered my questions even on Sunday! She was knowledgeable about the product and knew exactly what I needed to solve the problem with the lights on my trailer. I would do business with e-Trailer again in a heartbeat. They are the best!!!
Perfect match. Great quality.
Shipped promptly, arrived safe - packaged well, and works perfectly. Thank you!
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!)
Product as described and works as it should. I have this adapter on a 2008 Mercedes ML320 CDI and a 2008 Mercedes GL320 CDI. I have hooked both suvs into uhaul trailers with led lights and everything is working good.

Still working great. I keep in my trunk as part od my car kit.
Works perfectly on my Porsche 955!
Super fast delivery!!!
The adapter works great
Works great!
The product was exactly what I needed. Thanks for the help.
Works like a charm.
Doesn't work with my 2021 GMC 3500 HD Sierra. The 7 way works with trailers but I can't get the adapter 4 way to work with LED lights. The truck sees that there is a "trailer" attached but the LED's don't work. If I put the LEDs on a 12V battery they all work brilliantly.
Called CURT. They didn't know what would allow LEDs to work with my truck.
Looking for a solution.

A simple and perhaps silly thing to do would be to make sure that everything is properly seated on both the trailer side and vehicle side. Additionally, this part does have a one year limited warranty you may want to look into if making sure things are plugged in all the way doesnt help.
Was having a dilemma about how to address the hyperblinking and other issues with my trailer LED lights. This worked perfectly, and was quick and easy. Seems to be a well constructed product as well. 2021 Sprinter
I ordered a series of parts to use a hitch extender for my truck camper. The process was easy, the online specs and details ensured I ordered the correct parts. Everything works as advertised a year later. I’m pulling a 16’ enclosed Sure-Trac trailer for my UTV and it lights up the night. Thanks etrailer for an easy process.
