Video Transcript for Curt T-Connector Vehicle Wiring Harness Installation - 2019 Subaru Legacy

Hey everyone, Shane here with etrailer.com. Today, I have a 2019 Subaru Legacy. I'm gonna walk you how to install the CURT T-connector Vehicle Wiring Harness with four pole flat trailer harness. For our wires are going to look like when it's installed, it's going to be designed to live inside the vehicle and when we're ready to use it. You simply hang it out over top the rubber seal, make sure it's staying away from the connector point. Close your hatch, or close your trunk lid.

Connect it to your trailer and you're ready to go. When we're not using it, we can simply roll it up, throw our dust cap on it, and it can be stored right underneath our panel in our little storage compartment here above our spare tire. This is going to give us all the proper lighting functions that we're gonna need to safely tow a trailer, both turn signals, running lights and brake lights. It's going to come with a nice dust cap. So when we're not using it, simply install the dust cap on it keeps your connection from getting corroded or anything clogged inside of those.

We're going to have three amps per circuit for our stop and turn signals. Five amps per circuit for our tail lights. It's not going to be great for obviously pulling a trailer, but what if we had a cargo carrier or cargo box that was big enough that covered or partially covered tail lights, where nobody behind us can see what we're doing. There are options for some cargo carriers that you can mount lights on them. You simply plug this into them.

And then it gives you your running lights, your brake lights, and turn signals on the back of that cargo carrier. Basically take up for what's covering your lights so that again, really going you're safe. This is going to be adaptable to work with five, six, and seven pole plug, which you can find here at Etrailer. As far as the installation process, pretty simple and straightforward. I'm going to plug them behind each taillight.

So we don't have to do any splicing there. It's going to have a converter box, the converter box filled with potting material and what the converter box does it protects, the vehicle factory wiring from back, if there's a wiring issue on the trailer side. We're gonna have a power wire that runs up to the battery. It's going to be connected to a fuse holder and connected to the positive side of the battery. Other than that, that's all there really is to the installation portion. Now that we've gone over some of the features, let's go ahead and walk you out to get it done. Start your installation. We need to get in the truck. We're gonna remove our floor coverings, including the foam pad. That's sitting here underneath your floor. Once you get that removed, you're gonna take a trim panel tool on your threshold. You're gonna have three push pin fasteners. Remember to remove all three and then we're going to remove the threshold. We're just going to pull up and then we'll set that aside. And we're going to come to our panels. We're going to have the tie down, all we're going to do is spin it. And it'll allow you to pull it out, remove this fastener here. And then we're going to have one up here. Once you get those off, we'll be able to pull our liner out. We're gonna repeat that same process, on the other side. When it comes to the taillight on our driver's side. We're going to look through this white plug. We're going to push down on the taillight on the top. Disconnect the wiring on our wiring harness north, the yellow, red, and brown wire. We're going to install that in its place plug one end into the wire we just disconnect, the other one's going back into the taillight. And we'll have our ground wire. It's going to come with self tapper, however this bolt right here, holds our taillight in place and it's on a metal surface. So I'm just going to loosen that nut, slide this on and reinstall the nut. We can do it on either one of these. I think I might do it on this one. That way I can mount my converter box down here in this corner and it doesn't affect me putting this panel back in place. Taking that eight millimeter socket, we can remove that top. Ran two sided sticky tape from our kit, peel off one side install on our box. Doesn't really matter which side. Push it in place like that. I take our green wire and our four pole wire, we're going to run it right over to the center of the vehicle, just like that. Next we're going to take the black wire coming off our converter box. It's going to be pre-stripped and we're going to install the butt connector. We're going to take the bundle wire that comes with our kit it's going look like this. We're going to take one end we're going to strip it back and install it in the other end of the butt connector. I'm going to take some electrical tape and I'm going to run around that butt connector. Next we need to get the other end of our black wire out of the vehicle because we're going to be running up front and to engine compartment. There's a plug down in that corner that we can go through. However it's kind of hard to get to. We don't really have a plug here that we can just drive it through to. So if you look right here, we have a little flap. This is to release air pressure. When you close your doors. We can take our wire and we can feed it right down through one of them. And it'll come out underneath the vehicle. Once you have everything done on that side, you can go ahead and reinstall your panel. We're going to route the green wire over to our passenger side, install it the same way. That's when we need to get our black wire ran up to the front of the vehicle, to the engine compartment. Let me get it done real quick and I'll show you how I did it. When you're running your wire up, you want to make sure you're staying away from anything hot or moving. Since our exhaust is sitting right here, what I did is I took out this fastener, this fastener, took my wire and tucked in behind this plastic panel. Re-installed those, bring the wire right up you can see it right there. Behind here there's a bracket right there going over the top of it. Then you have these existing hard lines, right Existing wiring and hard lines over the top of everything here, it came down right over here. See we're my line is. Once they got to here, took out a couple of bolts here and then push the fasteners all the way up along this edge, pulled down this panel and tucked my wire up underneath. Once you get up, once we get up to here, right about this end, went straight across. This is my wire. I have a pull wire that I had sent down previously from up top, you can use a wire hanger and really use anything. I'm using an airline tube. I'm going to make sure when you run this up, you have your steering arm right here. It's going to rotate right here at this knuckle. So you can see what I did. I got behind this hard line, behind this hard line, behind the hard line there on top. When I pulled up my wire on these hard line they're going to hold my wire away from this knuckle. See where I came up, what I did is, I ran the wire back behind a brake booster, ran it through underneath this wire. I'm gonna run it underneath this positive cable here to the positive side of the battery. We're going to cut it down to size first. Might cut it about here. Strip back the end. Then add on a butt connector. You want to add heat shrink. You can add that on as well. You can find those here at Etrailer. They do not come with your kit though. Take off the two ends here on our fuse holder. One end, will go in here. I'm going to take some electrical tape. I'm going to tape up this end. Put this in we're going put a ring terminal. Then we're going to attach edge to the positive side of our battery. While we do that, I'm going to get my wire zip tied. Right in here. I'm going to run this through here. Through my cap. 12 millimeter socket and remove this nut. Take our ring terminal. Want to make sure that the fuse is not in the holder We install it on the positive side of the battery. Re-install the nut. Once we get it tight, we can install our fuse. Once we install the fuse, we can test it out and make sure it's working correctly. Then we'll test everything out and using part number I, two, six. Left turn, right turn, brake lights, running lights. Once you tested everything out, you know it's working correctly go ahead and install your dust cap. And you're ready to go. And if your looking at end installation on the car tee connector, we have a wiring harness with four pole flat trailer connector, on a 2019 Subaru legacy..
