How to Install the Curt T-Connector Vehicle Wiring Harness on a 2020 Honda CR-V


Ryan: Hey everybody my name's Ryan, and here at etrailer, we install, test fit, and review a lot of different parts. That way we can try to answer any questions those of you might have. That's exactly what we're doing here today on our 2020 Honda CRV. We're going to be taking a look at and showing you how to install the Curt T-Connector Vehicle Wiring Harness.A lot of people use these CRVs to do a little bit of everything. I think it's really well known that these are great all-around vehicles. So, with that being said, a lot of people not only use accessories, but they also do a little bit of towing as well and that's where the wiring is going to come into play.

You're going to need it to transfer the lighting signals from the back of your Honda to the back of your trailer, keeping you safe and legal.What's really nice about this kit is whenever you're not using the wiring, you're not even going to see it. It's not going to take away from the looks of your Honda. But whenever you are ready to use it, it's going to be super easy. If we open up our hatch, the wiring is actually going to be stored inside. So not only is it out of sight, but it's also out of the elements, so it's going to stay protected.

So if we open up our floor covering, you can see our wiring is going to be stored in the compartment down here. So whenever we're ready to hook up to our trailer we can simply just drape our wiring over the threshold here and close the hatch on it, and that's perfectly acceptable. That's what the wiring is designed to do. I will say anywhere is fine, other than the latch, you don't want to get it hung up in there because it could potentially get damaged.Once we have it draped over, we can close up our hatch and plug into our trailer and with this kit too, it gives us a lot of length here, so we shouldn't have any issues plugging in it. The connector here is going to have a nice thick, rubber dust cover so we shouldn't have to worry too much about any corrosion or anything like that.

I do suggest, especially if you use this a lot, just from time to time, to apply some dielectric grease to the terminals, that way we can ensure these will stay in perfect shape. What's nice too about the dust cap, let's say if you drop your trailer and you plan on coming back a couple hours later to pick it up, you can always just kind of wrap this around the hitch here and leave it temporarily stored like that, so really useful, especially if you have a bunch of stuff in the back of your car, you don't have to try to put it away just to have to pull it out a few hours later.One thing I really like about this kit is the fact that it uses a module box and what that's going to do is protect your Honda's factory wiring if a short or anything like that we're to occur on the trailer side. For me, that's really important. It really gives me some peace of mind. These newer cars have really advanced electrical systems and you wouldn't want to do anything to jeopardize that.

With this kit and because of that module box, it's something you're not going to have to worry about.One of the things a lot of customers ask about is locating the factory plug because this kit does utilize a connector that Honda already has back here. It simply just plugs right into there. But it can be a little tricky to find, you don't have a ton of space. With that being said that connector plug is located right here in this area, just behind the panel. During installation, I'll show you what panels I removed and how I took them off to get to that plug. Speaking of which, let's go ahead and do that together now.To begin our installation we are going to be here at the back of our CRV and we're going to need to open up the rear hatch. And what we're going to need to do is remove some panels that way we can locate our factory connector plug. So the first panel we're going to take out is this floor covering, it's pretty straight forward you can just lift up on it, pull it out and set it off to the side. Then we're going to have to remove our threshold here. So this is two different pieces. You're going to have a small piece in the center, and to remove it you can just kind of grab the bottom and pull, and that's going to release these clips here, set that to the side.Then we can remove the actual large portion of threshold as well. So again, same deal, just kind of grab one corner, pulling up, work it off and set it to the side. Then if we move up, we're going to have this panel that runs across the top here. We need to pull that off as well. Pretty much the same deal you can kind of just grab one corner of it and start to work it down.Once we have it off we'll set it to the side. So these are the fasteners that's holding this top panel end. If one of them falls out, not really a huge deal, you can simply just take it and slide it back into place. So then if you move in just a little bit, you can see right here on this flat portion of the panel, we're going to have a cargo hook and what you're going to do, we need to pull this out so you can open it up about halfway and then underneath it, on the bottom side, if you take a flathead screwdriver, there's a white tab in there and you can just kind of push it down and while you're pushing it down you can pull that whole assembly out. So here's kind of a better look at that white tab. You can see it in there, and you just push on it and that's going to allow you to release it.If you look on the driver's side, we're going to have this handle here that folds our seats down, and if we kind of open that up, there's going to be a small little cover behind it. And we can take a flathead screwdriver, kind of push down on it, then flip it out of the way. And behind there, there's going to be two Phillips head screws. So go ahead and pull those out. Now what we can do is pull these panels out a little bit and our connector plug that we're looking for should be located behind them. So what you can do, is kind of just peel back this weather stripping some and take a trim tool or something similar and kind of start to pry behind the panels here.You don't need to take these completely off, we just need to free them up that way we'll be able to kind of peel them back and locate our plug. So once this bottom portion of the panel is relatively loose we need to do the same thing for this upper portion. The connector plugs should be located behind it. And if you look through the opening where my tool is you can see a connector plug with some brownish tape around it. That's going to be the connector plug that we need to plug our harness into.So what I'll do is cut this tape and be able to pull this plug out a little bit that way it's easier to see and work with. So after removing that tape, it gave us a little bit of extra working room, but not too much. So it is a little tight back here, but that's okay. Once we have that done we can take our new harness and one end of it is going to match up with the plug and so we're simply just going to plug those ends together.Now that we have it plugged in we can grab our included fuse and place it in the fuse holder. Close up our dust cover and then what I'm going to do is take our module box and secure it somewhere behind the panel here. That way it's not bouncing around when we're driving down the road. So I'll go and do that now and then show you what it looks like once I have it done.So I went ahead and secured our module box and I just used a couple of zip ties and secured it to the body of our vehicle. And our four pole wiring actually just runs down and you want to make sure to push it out of the bottom side of this panel here, that way we can kind of store it back here by our spare tire whenever we're not using it.Now before we put everything back together, it's a good idea to check our wiring to make sure it's working properly. I do suggest using a little tester like this one here. You can find it here at etrailer and I said it because if something on your trailer is faulty, it may give you a false reading. With that being said, we'll hit our brakes. We'll turn on our running lights. We'll check our left turn signal as well as our right turn signal. So now that we know our wiring works, we can start to reattach all of our panels and put everything back together the opposite way that we removed it.Whenever you kind of start doing the side panel you want to make sure that the weather-stripping isn't pinched behind there, it wants to sit on top. So what you can kind of do is kind of just use your hands to roll it back and work your way down the panel. And that'll finish up our look at and our installation of the Curt T-Connector Vehicle Wiring Harness on our 2020 Honda CRV.
