Video Transcript for TorkLift Wiring Harness Extensions For SuperTruss Hitch Extenders Review

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.

Best buy ever. Now I have a safe reasonable connection, without stretching

Exactly what I needed.

- TLW6042

The Torklift Wiring Harness Extention shipped quick and good condition. I plan to use it for a slide in truck camper. It will be used to extend the electrical from the camper to truck and give me another location to disconnect it from truck when the loaded hitch hauler is on. The truck does not have a isolator for the battery so I will use the manual disconnect and mount it in a easier to reach location.

Ask the Experts about this TorkLift Trailer Wiring

  • Converting 7-way Round Pin Trailer Connector on Semi Tractor to 7-way Blade for Towing RV
    Typically, the 7-way blade and the 7-way round pin are wired differently. The 7-way blade combines the brake lamp signal with the right and left turn signal circuits, but the 7-way round pin will carry those three functions on three different circuits, one right turn, one left and one brake lamp. What I'd recommend you do is install an additional 7-way blade style trailer connection like # PK11898 on your semi-truck. Be sure to look at the product description page for the wire color...

  • Adapter from Truck with 7-Blade to Camper with 7-Round Connectors
    An extension is going to be male on one side and female on the other. We have a 4 foot extension, part # TLW6042, that's a 7-way on each end. We don't carry an 8 foot long extension but we do have a 10 foot, part # TLW6510, that should work for you.

  • Recommendation to Extend Existing 7-Way Connector to Clear Truck Bed Camper
    For an adapter that will extend your existing 7-Way beyond the rear of the truck bed camper, I recommend the TorkLift Wiring Harness Extension # TLW6042. One end of the wiring harness will plug directly into your current 7-Way, while the other end features a 7-Way port for connecting to your boat trailer. This measures exactly 4 feet long, end to end, so it will work perfectly. I have attached a short video demonstration on this product that you can also check out.

  • Torklift Camper Tie Downs for 2021 Ford Super Duty with 8 foot Bed

For a rubber mat that fits your bed you'd then want the Westin part number # 50-6415. For a 7-way extension we have a few options like the part # TLW6024 which is 24 inches long, part # TLW6036 which is 36 inches long, and part # TLW6042 which is 42 inches long.

  • Can TorkLift Wiring Extensions for SuperTruss Hitch Extenders Be Shortened
    You could cut and resplice the # TLW6532 7-way wiring harness extension to shorten it, but I'd personally be leery about that as the splices could possibly be vulnerable to the elements and corrosion. The best practice would be to get a harness in the correct length so you don't need to cut it up. TorkLift offers the extensions in the following lengths: • 24 inch, part # TLW6024 • 28 inch, part # TLW6028 • 32 inch, part # TLW6032 • 36 inch, part # TLW6036 • 42 inch, part # TLW6042 •...

  • 36 Inch SuperTruss Hitch Extender and Wiring Extension For TorkLift SuperHitch
    To ensure that you actually need a 36 inch extender, and not something a little longer or shorter, TorkLift recommends taking the following measurement: If the camper is mounted on the truck, Measure from the face of the truck's rear bumper to the outside edge of the camper's bumper. This is the length of the extension that you need. If the camper is not mounted on the truck: 1. Measure from the inside of the front of your truck bed to the outside face of the truck's rear bumper. 2....

  • 7-Way Wiring Extension for Camper with Jayco Square Connector
    The Curt 6-Pole Square wiring extension # C58034 uses two Jayco style connectors, both a vehicle side and a trailer side connector, so it can serve as an extension. If you want to install a standard RV 7-way plug on your existing trailer wiring so that the trailer directly matches the connector on the Honda you can use plug # A7WCB. Another route is to install a junction box with a built-in 7-way, such as etrailer # e99011. This box mounts on the trailer and accepts the existing trailer...
