Video Transcript for Review of CURT Custom Fit Vehicle Wiring - Fifth Wheel and Gooseneck Wiring - C58FV

Hi there, I'm Michael with etrailer.com. Today we're gonna take a quick look at this CURT 5th Wheel and Gooseneck custom wiring harness. This is gonna provide a 4-way and a 7-way blade style connector in your truck bed so that you can very easily hook up your 5th wheel and gooseneck trailer and not have to worry about the hassle of trying to reach down to the connection point that's down by your bumper. And this is going to mount in your truck bed sidewall tailgate post or wheel well and it is going to be a custom fit for your 2019 and newer GMC Sierra and Chevrolet Silverado 1500, 2500, and 3500 with a factory 7-way. So this will plug right into your factory wiring. You're not gonna have to do any cutting or splicing into the wiring.

Basically, you'll just take your connector off. It's going to expose this kind of connection here that's currently on your vehicle. You'll then plug that portion into this and then reconnect your plug here. So that's going to re-complete that circuit. So your bumper mounted 7-way is still going to be working just fine, just like it originally did.

And then that's also going to then send your signal up to your truck bed. This is seven feet long and it is going to reach up to the truck bed so that you can more easily connect your 5th wheel and gooseneck. Make sure that you've got all the wiring that you need there. They do include instructions for you to get this installed. They walk you through that installation process even though it's very simple and they give you all the pictures that you need as well as some zip ties and to hold your wiring even place where you need it.

So very easy way to kind of extend your wiring harness or your wiring connector up into your truck bed so that you'll have much easier time hooking up when it's time to tow. So that completes our look for today. Again, I'm Michael with etrailer.com. Thanks for watching.

Super easy to install. The hardest part was pulling the old plug from the harness to the bumper connector. Although the instructions said to feed the bed connector from the bottom it was easier to feed the bed connectors (even though there were two) into the upper bed slot and then under the bed.



by:

Simple installation, worked as expected. With spray-in bed liner, the clips did not latch but no fault of the product.



by:

Product assembly fit and installed as it should, and has worked well all year , highly recommend

Solid harness but it’s sold as a direct fit for my truck and the way the harness is routed does not allow it to work on my truck. The connection to the outlet routes directly into the steel frame support of the box of my truck.

Stacey A. was very helpful and guided us towards the replacement product that we needed. Excellent customer service on her part.

Have not had time to install it yet but looks correct and as described. Product was delivered 1 day ahead of Est delivery date.
