Trailer wiring was too short for use with a weight distributing hitch.
Cut this to length and attached a plug on the end.
Plug the trailer wire harness into this extension and other end to truck.
Saved cutting and extending original trailer wiring.
The quality of this trailer plug connector should make it last forever! The seal at the end will withstand the constant bending and twisting that this daily-use utility trailer will put to it. The blade style RV plug end will fit any factory equipped pickup receptacle so I can use multiple tow vehicles.
Right now 3 stars. Received the connector 12 Oct 2021. The cord on the trailer had the same connector on it which worked if you manipulated the pins to make connection (reason for replacing). The wiring colors on trailer, old connector snd new connector are the same, so adding new connector wasn’t a problem. When I plugged into the vehicle and tried the lights, nothing worked properly. The only time any lights came on was when right turn or hazard switches were activated and ALL the lights on trailer came on flashing. Tried the connection on 2 vehicles with same result. Called etrailer and they are sending another connector. Will give update then.

The harness is of great quality and well marked for installation.
The cord worked well, the length was just right for my set up!
This umbilical has different gauge wires within it. The heaviest gauge being #10, which should correspond to the brake power supply and ground. It does not. Only one of the two #10 wires corresponds with brakes, the other one is going to a light’s blade on your vehicle’s socket. So all the effort spent on ensuring that you wired your brakes with the required #10 wires is lost when you splice this connector to your trailer. You’ll have #10 positive to your brakes yet the ground will be #12 or #14. Grounds are always the weak link in 12 volt electrics.
Excellent Product from a great Company

Great
Used this on my snowmobile trailer. The cable outer jacket is to rigid (Not flexible). Gets worse in colder temps. Don't recommend it for cold use. Picture is in garage at 53F. Cable is so stiff it won't fall on the floor.
As always, I got exactly what I ordered, on time without any glitches. Etrailer are my go to guys for all my trailer accessories. Great company to do business with.
Very good quality
Great quality, affordable and easy wiring. The extra length let me change the configuration to better suit me trailer/truck setup.
the wire colors doesn't match standard wire colors, need to determine which wire color corresponds to what position on the connector end. other than that quality and construction is good.

The Hopkins part # H20043 uses the following wire coloring: White Wire - Ground Red Wire - Left Turn and Brake Brown Wire - Right Turn and Brake Green Wire - Tail Lights Blue Wire - Brake Power Black Wire - 12 volt or hot lead Yellow Wire - Aux. I recommend wiring your trailer by function and not color. If there is a circuit you do not need for any reason it does not have to be connected.
It works. After I spent the time putting this in, figuring out the color code, then testing it in a socket, when I realized that the plug only uses one contact blade per wire. Which is plainly shown in the picture but I was expecting a higher quality plug like the one that I replaced so didn't notice that in the picture. In is in and works. Not worth spending the time and money to replace it until needed.
Be careful! The wire colors on this harness do not follow standard trailer colors. Make sure you follow the chart listed with the product.
Check the function of your wires on Trailer and Truck! Product is perfectly fine. It's wired for RV Traditional. My Truck is RV Traditional. My Trailer is SAE Standard. Took me a minute to figure it out. My advice... hook this up to your truck and with a meter and test light confirm the function of each wire. Do the same with your trailer. If you don't understand that... hire someone that does. eTrailer.com awesome as always.
Placed order on Saturday, hadn’t shipped by Tuesday. Called and spoke with Alex J who was professional, knowledgeable and helpful. She did a great job.
I fabricated a receiver hitch motorcycle rack, I used trailer wiring and led lights, so I have lights on the rack. Just plug it in to the truck trailer plug. Good quality and instructions with etrailer supply's.Thanks
Everything was Delivered quickly. The plug fixed my issues with my trailer brakes and the new jack is so much better than the manual recommend it to everyone easy install
ALWAYS A PLEASURE DOING BUSINESS WITH E TRAILER.
This is the second one I have ordered from E trailer and it works well.
My horse trailer OEM unit was brittle and stiff, after just a few years. This new wire harness from etrailer fixed the problem and was easy to install. It is even a little longer then the OEM, so there is more more room for turning sharp corners.

Still works great. Great connection with the tow vehicle, and still very pliable wires!
Bought a 20 year old horse trailer and needed to rewire it. The original pigtail had a 6 terminal plug, my new pick-up had a flat four and a 7 pin. When I bought it the guy gave me a 6 to 7 pin adapter but it didn't allow electric brakes. They are required in my state for a trailer over 1500 lbs. Think trailer with two horses. So I bought this pigtail. It is top quality and has large gauge wiring. I also needed break-away switch so I needed a battery. This pig-tail has #10 wires for both 30 amps (+12V) and Chassis ground. This really puts a charge in the trailer battery. (would do the same for an RV) Then #14 wire for the brake signal. This plugs right into the seven pin plug on my pickup with the tow package. Highly recommend.
Works as designed
