Extension plugs into your existing 7-way, RV-style connector to route functionality from the rear of your vehicle to your truck bed for quick, easy hookup of your 5th-wheel or gooseneck trailer.The cable was delivered promptly and it functions as advertised. Be aware that it is a thick cable if you are planning on running it through tight openings or sharp turns. I bought it mainly to allow connecting to a trailer while not hitched to it and to allow in-line balasts to be on a cable rather than putting a strain on the socket on the tow vehicle. But I also wanted to check when brake lights came on when coasting in various modes of a PHEV. I gently left the tailgate resting on the cable rather than closing it for that test.
It wasn't what I explained i needed. The product is perfect. What I asked for was an 8 ft that I could hardwire to the trailer that had the plug on the truck end.
Heather A - 04/01/2022Works great, no worry of unconnected wiring from too tight harness
Good quality, just what I needed
Pretty pathetic service from etrailer. Order place on Aug 25th with ETA of the following Friday (1o days). But nope, I wait. It finally (and supposedly ships) on Sept 7th (13 days later). On Sept 14th I received a confirmation that my items were delivered, but nope. Not to my house anyway. Avoid these folks if you want something to arrive when they say it will arrive.
Brooke M - 09/23/2021I had a great experience. Ordered the wrong cord, realized it a day later. Was able to cancel the order, and order the correct cord. It showed a day early. Very good customer service.
This extension is well made. I have to admit I was really disappointed that they choose to save a few pennies and not include screws or bolts for the female end.
When boondocking for a extended time, I tried hooking the supplied cord from my new tent camper to my truck's socket, but it was impossible with out collapsing the end of the tent which extends over the tongue. The supplied cord was just 4 inches too short, how annoying! With this extension, I can now recharge the batteries without having to partially disassemble the camper.
I bought the adapter based on advice. The 7-Pole Round Trailer Connector Adapter # PK12727 is NOT the same as the Lance plug. Adapter is good quality and arrived quickly bu unfortunately would not work for my Lance camper factory plug.
Mike L - 10/02/2018Good product. Fit perfectly. And as always Tim, The good folks at etrailer did a great job getting it to me. I have bought several items from etrailer and they all have been good quality components.thx.
Well made, should work well for my condition where I need a longer 7pin round cord. Appears to be constructed of quality materials.
Arrived as described. I order all my trailers stuff form here. Great company, great help and very friendly
Worked great!
I cut the unit in half, and connected one side to my electric jack and the receptical side mounted to my battery box
Excellent product!!
Great 7-Pin trailer extension cable.
We purchased a new 5th wheel so had to upgrade the wiring harness. This harness was a simple plug and play and works great with our new 5th wheel. My husband leaves it plugged into his wire harness under the bumper and has it run up between the tailgate and the back of the bed and just leaves it in his truck. We do have a cover on our truck so it is not exposed to the elements. I would highly recommend this wiring harness to anyone.
Just what I was looking for! Our fifth wheel has a short cable on hitch and when getting in tight turns or steep angles would come unhooked. This product allowed me to mount in bed and took care of issues. Quick delivery so we'll be ready for the next trip!
This is the cats meow. Took maybe 15 minutes to install, most of which was drilling the hole. Connections were spot on. After a year still working great. If you haul a 5th wheel, gooseneck or just need an in bed ug I highly recommend this item.
Decent hitch but etrailer again shorted me parts.
I contacted etrailer and told them the parts that were shorted.
They did not take responsibility and blamed it on the manufacture.
This is now the second time I have had problems with etrailer in the last 6 months.
Now my customer is pissed that the hitch will take an additional 1 week for the missing parts to be shipped.
I am done with etrailer.
Exactly what I needed and had been looking for. My trailer wiring wasn't long enough for my new truck and I need an extension. Thought about making one myself but this was so much better. I won't hesitate to look on your web site for any future needs.
Appears to be well made. Price was right and as always the service from etrailer was second to none. I'm sure by the look of it that it will perform as intended.
The 7-pin extension is the perfect solution, allowing me to work on the trailer lights and brakes while at home. I am impressed with the selection of products available and will undoubtedly make more purchases throughout the year!
Easy to connect to existing wiring harness, allows for extra space. Very sturdy connection.
The extension cable if perfect for the gooseneck trailer to semi truck 5th wheel. No need to cut up and extend the trailer cable.
This product is well-built arrived promptly and worked as expected. After a year of using it it is still working flawlessly
Hugh quality molded cable and connector s.
