Curt T-Connector Vehicle Wiring Harness with 7-Way Trailer Connector

Video Transcript for Curt T-Connector Vehicle Wiring Harness Installation - 2021 Honda Passport

Hey everybody, Ryan here at etrailer. Today on our 2021 Honda Passport, we're gonna be taking a look at and showing you how to install the CURT 7-way vehicle wiring harness. People use these Passports to do a little bit of everything, which does include some relatively heavy towing. You know it makes sense, the hitches available for them are very capable and these are really capable SUV. So people get out on the road a lot pulling around some heavy trailers. And those larger trailers are generally gonna have the 7-way round type connector.

And this is gonna allow you to hook up to that trailer. That way, all your lights work and everything else. You also get your reverse light circuit and your 12 volt auxiliary power as well. So you kinda get everything you need there. And if you ever need to, say maybe pull a smaller trailer or one that has a 4-way flat connector, not a big deal, you can always just grab an adapter like this, which will allow you to plug into the 7-way and then that'll convert it into 4-way flat.

That way, you can still tow the smaller trailers if you ever need to. So at the end of the day, it's just nice to know that your Passport is not gonna be limited to towing only certain types of trailers. With this wiring, you're gonna be able to pull those larger ones and plug into them. And if you ever need to pull a smaller ones, you can always use one of those types of adapters and that'll allow you to do that here as well. A great all around kit that's gonna get the job done.

Now as far as the installation goes, really not too bad. For the most part, it's plug and play, but you do have to take some things apart to route the wires and actually get everything plugged in. So it will take you a little bit of time, but really shouldn't give you a lot of issues. Speaking of which, let's go ahead and do that together now. To begin our install, we're gonna be here at the back of our Passport.

And what we're gonna need to do is locate some factory connectors, which will be inside. And so we'll open up our hatch. And what we're gonna need to do is remove some of our floor coverings. So let's go ahead and grab everything off the floor that we can. We'll just slip the stuff off to the side for the time being. This one we can probably just fold up. That way, we don't have to deal with trying to get that completely removed. So to get these trays out, we're gonna have a couple of latches here. We can just rotate them quarter turn, and we should be able to just lift up on this and move it out of the way. Now, we can go ahead and get the spare out of the way. So we'll rotate this T-handle till it comes out. Eventually we'll get there, here, pull those out and grab the spare and get this out of the way as well. And we might as well get this out of the way too, this foam compartment with tools in there. And so this locked off and we'll be able to remove it. Now on the corner here, towards the back of the vehicle, we're gonna have a push pin type fastener. We need to remove that. You can use a trim panel tool or a flat-head screwdriver to pop that out. We'll be set up the exact same way on the other side, so I went ahead and removed that one as well. So with those removed, you should be able to grab up on our carpeting and kinda work it out from our vehicle and get this out of the way as well. Just over here on the driver's side, we're gonna have a couple of fasteners that we need to remove. If you look at our cargo hook here, we can flip that up. Then there'll be a cover, plastic cover, and you can kinda get a pick or a flat-head screwdriver behind there and pry it up. And what that's going to expose is a Phillips head screw. Now the screws in there are really tight, so you can take the screwdriver and try to turn it, and you might get lucky. If chances are good, you'll probably strip it. But kind of an old trick here, every screwdriver is gonna be a little bit different, but a lot of them will have like the, have a bolt almost right there, or sometimes the handles will allow you to put a wrench, a box wrench over the top of it. And that's a case with this one. So what this is gonna allow you to do is put downward pressure on that screwdriver and turn that wrench, and that's gonna help you break it free. And while you have some extra leverage and by pushing down on it while you're turning that wrench, you're not gonna have to worry about stripping it out. So it's just kind of an old trick there, if you're having trouble with this. We'll go ahead and remove this and set it aside for now. If we continue to move up this pillar here, we're gonna have one more fastener. So again, behind this cover, just release it. There's gonna be an eight millimeter bolt. So this one we'll grab our socket, and get this removed. Now we go ahead and remove our threshold. So with this, you just pull straight up on it. Get this out of the way. And over here towards the middle, we'll see this plastic teal here. We're going to release it as well. So take a trim tool or a flat-head screwdriver and get these pop out. These are pretty brittle. So make sure you're holding them good before you start trying to go pull off on them. And that way you don't break them. It's like this and this, get out of the way for now too. Now, if we take this panel here around the driver's side, we can pop this thing free. Take a trim tool or something similar, gonna work behind it and just kinda work our way down. It's gonna release some fasteners. And we should be able to look back in here and locate our connector plug. So the plug that we're looking for is up a little bit further. Can't pull our panel out because we have this connector. We'll disconnect that, you push down on the center tab, pull it out. Now we can kinda work this up and out of the way, and you can see we're gonna have this exposed connector, right there. That's the one that we're gonna be working with. And the one that we're gonna use to plug in our new harness. So this is a grommet here that we're gonna use throughout our wiring from the outside to the inside of our vehicle. What you want to do is push on grommet and you wanna push it down towards the floor, like so. And now what we're gonna do is go from the bottom up. So we'll get underneath our vehicle and start to get our wiring routed. Now underneath our vehicle, and here's our grommet, push out of the way. We're gonna use that hole, we're gonna take our new harness, and feed that up into the inside of our vehicle. So we'll just carefully work everything in. So now that we ever wiring in here, we can peel back our panel there, take the connector plug, and plug this on in. At this point, we can grab the included 20 amp fuse, get that plugged into the holder, close up that dust cover. And I wanna mention this connector here, in our case, we're not using it. But if you had to disconnect the backup sensor harness, you're gonna wanna reconnect it to this here. That'll allow it to still function. But in our case, we don't need to do that. So that's what this is for. Chances are pretty good, you're not gonna have to, but in case you do, this is why this is here. Now we can take the white wire here with the pre-attached ring terminal. This is gonna need to get grounded to the body of our vehicle. We have a thick metal bracket right here. That'll work perfectly. We're gonna take this self-tapping screw, get through there, take our drill and you just secure this to that bracket. This point, we'll grab the two-sided sticky tape, and this is what we're gonna use to secure our converter box here, peel off both ends and make sure that the surfaces are nice and clean. And this is gonna be a little tricky to see while I'm doing this, but it's gonna get on a nice flat surface. Now behind here, and push down on it, make sure it's solid. That way, we can ensure we have proper adhesion. Now we need to do is trim our grommet. That way, it'll fit around our new wiring and still we have to go back in place. So I'm just gonna cut a slit in it with pair of snips here. And when you're doing this, just be careful not to cut those factory wires. And you don't wanna create any issues there. So you wanna be deliberate, pay attention to what you're doing. Cut that opening there, kinda work this back down. And once you have it, tuck back in there like that. It actually sealed up pretty nice, but be on the safe side, kit comes with some silicone. You can open that up. And we'll just put some sealer on this as well. Just kinda jam some of that in there. Now back underneath the vehicle, I went ahead and mounted up our 7-way connector to this bracket. This bracket does not come included. And in order to get this done, you will need a bracket to mount this up. So in our case, I just use a 7-way bracket because our hitch actually has a spot to mount that to. If your hitch does not have any bracket at all, you're gonna need a no-drill bracket as well as the 7-way bracket. So I definitely urge you to check this out because you're not gonna have a way to mount up your plug and you're not gonna be able to use it. So with that said, we're gonna take our 7-way connector there on the terminal side, and we're gonna apply some dielectric grease. This'll help keep it protected from corrosion and wear and tear. And then it's simply just gonna plug right into our 7-way, like so. And then with our wiring, what I'll do is go ahead and secure this. I'll come back and show you how it works. So we got this wiring secured, pretty straight forward, just run it along through here. And I used a peek lamp, secured it to this brace. That way, our wiring doesn't drop down, just run it right over our hitch where it plugs into our 7-way connector. Now we need to pop the hood and install some fuses. So lift the hood up, here on the driver's side, we're gonna have this fuse box, push on the three tabs, pop that up out of the way. This opening there, we're gonna take this 30 amp fuse, push that in. The opening right next to it, we're gonna take this 20 amp fuse and get this one installed. They're pretty small, they're kinda tricky. And then this one right here to the left of that 10 amp fuse, we're gonna take the 20 amp fuse and we'll get that in as well. And all these fuses are included. So you don't have to worry about them separately. Well, we have these hooked up. We're gonna put this back on. Now, we'll go ahead and test everything to make sure it's working. So now to test everything, I went ahead and plugged in this tester. And I strongly recommend using one of these as opposed to just plugging into a trailer because if your trailer has any faults, you could potentially think it's the wiring causing an issue, and this tester will bypass that. But that said, as something I have my key turned on. I have my 12 volt auxiliary power lit up. We'll try out our brakes. Our left turn, our right turn, our tail lights. And I'll start up the car, put it in reverse and make sure there's work as well. Now that we know everything works, what we can do is put all of our panels and everything back together, the opposite way that we removed them. And that'll finish up our look at and our installation of the CURT 7-way vehicle wiring harness on our 2021 Honda Passport..
