When your trailer plug is just out of reach, the TorkLift Wiring Harness Extension for 21" SuperTruss Hitch Extender - 7-Way RV gives you the extra length you need. It adds a solid 21 inches between the truck and trailer connection, keeping the plug from pulling loose during tight turns or when towing with extensions. The male 7-way on one end and RV-style female 7-way on the other make it simple to plug right in and go.
There’s no splicing or wiring guesswork here. This extension plugs directly into your existing 7-way, instantly extending power for lights, brakes, and charge lines. It’s a clean, direct connection that works just like your factory wiring—only longer.
Road grime and rain can cause corrosion if wiring isn’t sealed up right. This harness uses a tough plug-and-lead design with solid terminals to maintain good contact even after years of use. Periodic cleaning keeps the pins clear of dirt or debris so the signals stay strong trip after trip.
The connector housing has accessible screws that let you open it up for inspection or bracket mounting when needed. You can loosen the rear screw to release the cable or remove the mounting plate to attach a bracket. Using dielectric grease helps protect the contacts from moisture and corrosion so everything stays working smoothly.

Today we're going to be taking a look at the Torque lift line of wiring harness extensions for use with the super truck hitch extenders. These are available in several different lengths. Just depending on how long that hitch extender that you're using is going to be. This is Torque's Lifts 36" extension that matches their 36" super stress. If you're going with the longer super truss, get the longer. If you're going with the shorter, get the shorter. Really a nice option to where you can plug it right into the back of your vehicle, bring your power down to where it's right here, readily available and accessible for you to get to. What we're going to do is take our, what looks like a trailer plug end, we're going to pass it through our bracket.
It's just flexible enough we can kind of bend that bracket so allow it to come through. Then here's what we want, that's our 7 pole connector. We're going to be bale to hook our trailer up right here. We've got the nice safety chain connections there an then also our wiring connection. Slide that in.
We're pass our screw through the face there and then just put our nuts on the back. Now, the hardware's not provided so you'll need some hardware to pass through there. You can see our bracket's kind of got the oblong holes to make it to where it'll fit a lot of different style harnesses. I'm going to put a flat washer on to give our nut a good surface to bite to when we tighten it down. Now we can go ahead and tighten those down as well. At that point, we're mounted on, got a nice secure connection point.
We can basically just plug this right into the back of our truck. You don't want this to be hanging down underneath our hitch where it might drag or something like that. That will complete today's look at the Torque Lift wiring harness extensions for the super truck hitch extender.

Bought with 21" hitch extension for torklift super hitch. Appears to be good quality and will test out soon
This harness extension has served well in extending my connection to a more handy spot one my motorcycle rack on the back of my motorhome. Zero complaints. Quick delivery and reasonable price from etrailer too!
Excellent customer service and product
Perfect fit with my 21” hitch extension. Easy to install and hook up to the trailer.
I used this product as an extension to my existing harness because our new truck's plug in is located in a different place than the previous one and the chord would disconnect when turning. Not the intended purpose for this product but it works just fine.
My wiring harness works great. Best of all Etrailer ad my sales person was wonderful and understood exactly what I needed. I spent 3 hours on the phone and internet trying to find what I needed and none of them had a clue. This company truly has the most knowledgeable staff by far. I will not use anyone else from this point forward.
Towed the camped from NY to California and back and this worked perfectly with a hitch extension
My travel trailer cord was not adequately reaching my Expedition plug. Had already been pulled out when making a left turn. This extension worked great! Nice and secure fitting. Wrapped the excess once around the tongue jack for a better fit.
Way over priced for a non-weather proof extension. This extension would be exposed to water intrusion when installed. The wires into receptacle/plug ends are open for water seepage. This product appears assembled from off-the-shelf items, not molded for weatherproof integrity. This inferior design is not evident in the site photos of the product. And the price - twice as much as alternatives I have discovered since purchase. See the attached photos for the missing detail. I would likely return if I could and just assemble my own at a lower price. This item is not what I expect from eTrailer.

Its been a year and the extension cord still works great! Stays secure and gives enough room for turning.
