Fifth Wheel and Gooseneck Wiring Harness Installation - 2010 Toyota Tundra

Today on our 2010 Toyota Tundra, we're going to be taking a look at and installing the Draw-Tite fifth wheel and gooseneck wiring harness with a 7-pole connector, part number 20110. Here's what the fifth wheel gooseneck wiring looks like once it's installed in the truck. As you can see, it's tucked away nicely over here on the side of the bed. It's got this little housing for the 7-way connector that has a spring-loaded lid, in order to help keep out any dirt and debris. It's a nice, easy install. It comes with all the hardware that you'll need in order to install it. Something that's really nice about this wiring setup is that you don't have to run any extra wiring up into the cabin or under the hood. It just simply plugs in to your existing 7-way wiring. First thing we'll want to do to begin our install is we'll want to locate a good spot in the bed for us to mount this.

Curt 5th Wheel Wiring Harness Installation - 2015 Toyota Tundra

Today on our 2015 Toyota Tundra, we're going to show you how to install the Curt Fifth Wheel and Gooseneck Custom Wiring Harness with 7-Pole Connector, part number is C56000. To begin our installation, we're going to figure out to start where we're going to be mounting our 7-way plug. As you can see, this gives us an extension or a way to move these remotely from the wiring itself to allow us to hook up maybe a popup key or gooseneck, fifth wheel, stuff like that. Now, we're going to be mounting it somewhere over here in the back side of the truck, unless you need it somewhere else, each application may be a little bit different. I would avoid the sunk in areas. Those are really close to the bed side. What we're looking for is enough area for this once it flushes up against the truck there for this to pass through and also a plug that will be on that back side, so typically down lower in this area is a good idea.

Today on our 2001 Toy0ta Tundra, we'll be installing the Curt T-Connector Vehicle Wiring Harness with 4-Pole Flat Trailer Connector, part number C55378. We'll begin here underneath the rear of the vehicle, over here on the drivers side. You'll see that there's a large gray plug right here that actually has an end cap in it. To unplug this, we'll simply push in on the locking tab and gently pull downward. This is the wiring that we'll be tying in the new Curt T-Connector wiring harness to. Now for the box and the 4-flat end of the wiring harness, we're going to route it up here through the frame. This will allow us to protect the box, as well as give us a good flat area to secure the box using the 2-sided tape. We'll go ahead and use a little bit of rubbing alcohol to clean the surface first, before we attach the 2-sided tape to the box, and then attach the box to the frame of the vehicle. We'll go ahead and plug in our connection from the new wiring harness to the factory wiring harness, making sure that we hear the locking tab click into place. We'll go ahead and use a few zip-ties to secure up any excess wiring. Now for the 4-flat, we'll route it down here to the center of the hitch area. We'll then take the cover for the 4-flat, put it on the end of the 4-flat, and then loop it through the safety chain hole on the hitch. Once that goes through, we'll take the end cap and put it back over the end of our 4-flat.

Trailer Wiring Harness Adapter Installation - 2010 Toyota Tundra

Today on this 2010 Toyota Tundra pickup, we are going to install part number 37185. Also, we are going to use an install bracket, part number 118136 from Tow Ready. In this case what we are going to do is we have our factory 4-pole lose from the vehicle. Our 7 and 4-pole down to our 4-pole adapter is going to go on the end of this. Now we will take a few minutes to do some test fitting here because it is kind of close between the hitch and the bumper. So, we use our bracket. We can mount it this way or we can mount it this way. And we can mount it just like this. It does stick out kinda far. So what we can do is we can just take this bracket and flip it around. And if we are installing it backwards, it actually recesses a little bit. It sits a little tighter against the hitch and it is not the only thing that is sticking out further than the hitch itself. 1:00
