How to Install a Trailer Wiring Harness on a 2014 Chevrolet Traverse


Today on our 2014 Chevrolet traverse, we're going to be taking a look at and showing how to install the Tekonsha T1 vehicle wiring harness for factory tow package with seven way trailer connector, part number 118271. With the seven way, you're going to have more versatility with trailers. It also allows you to use trailer brakes, as long as you have a brake controller installed on your vehicle. This is what you're going to get in your wiring kit. You're going to get your seven way connector that's going to be hooked up on the back of your vehicle. You're going to have your plug, which this end's going to hook into your seven way once we get it ran. This end's going to hook into your existing wiring, which I'm going to show you how to install that.

You're going to have your fuses, your relays and you're going to have a few zip ties. What I'm going to use today, is I'm going to have a pair of wire cutters for my zip ties and I'm going to have a trim panel tool, so that I can reach up and pull out the wiring, which I'm going to show you how to do now. To start our installation, our wiring harness that we need to connect to is up here on the inside behind this panel. What I'm going to do is I'm going to pull it down using my trim panel tool because its connected into the side. You can see this is our wiring harness, existing wiring harness that is connected to our vehicle. You look down here on the bottom, has a square shaped area.

If you look on the wiring harness that we're connecting, the bottom of this one kind of has a square shaped add-on. That's the part that's going to slide inside of there. Now before we make our connections, it's a good idea to put some dielectric grease on your connections, kind of helps keep the moisture away from them. We're going to make sure we get some on all of our points here. This is what it looks like when it's connected. What you want to do is when you put the two pieces together, you want to make sure you listen for the click.

When you hear the click, you know you're connected. Now that we have it connected, we're going to route our wiring this way. We're going to go over top our hitch. We're just going to let that hang there for now. What we're going to do is we're going to run a zip tie right through here to get our wiring up there.

The reason we're going that is we want to keep it away from the exhaust. Now as you can see, we already have a welded on mounting plate here. Our seven way will not connect on there. What we're going to have to do is we're going to have to use this bracket here, part number PK12711U-26. Now the bracket comes with two self tapping screws to install onto your hitch. I'm actually going to replace it with these two bolts and nuts. Once we get these two nuts and bolts mounted here, we'll go ahead and snug it up just to hold our bracket in place. I'm going to use a Phillips screwdriver and a 3/8 socket. Now we can mount our seven way onto our bracket and we're going to have four corners to attach. Now that we have all of our hardware in place, go ahead and tighten everything up. Now that we have our seven way firmly in place, we'll go ahead and hook up our wiring. Again we're going to take some dielectric grease, we'll just put it on the mounting points here. Now as you can see, we have some extra wiring. All I'm going to do, I'm just going to bundle it up and I'm going to zip tie it right up here to the back of the hitch. Once we have all our wiring connected in the back, now we can come up to the front on the fuse panel and we can start inserting our fuses and our relays. I'll use a screwdriver, you just want to push that forward. Then same on these other remaining too. We're just going to set that aside. We're going to start with our 10 amp fuses. We're first we're going to do our trailer back up, which is going to be F8 right here. We'll go ahead and put our 10 amp fuse, one of our 10 amp fuses in that spot. Our next position is going to be right turn, going to be position F17, which is going to be right here. Our next one is going to be left turn, which is going to be position 21, which is directly behind it. Our last 10 amp fuse is going to be for our trailer park lamps, that's going to be position F41. Next we're going to move onto our 30 amp fuses. First one's going to be our trailer power, it's going to be F30, which is going to be this one here. Our next one going to be for trailer brake, it's going to be F34, which is going to be right behind it. Next we're going to have our relays. One is going to be right turn signal, it's going to go in R16, which is going to be right here. Next one's going to be left turn signal, it's going to be in R15, going to be right here. Our next one is going to be for our trailer back up. It's going to be right here on this end. Now that we have all our fuses in place, we'll go ahead and put our cover back on and we'll test it out. We have our running lights, our brake lights, left turn, right turn. That'll do it for the Tekonsha T1 vehicle wiring harness for factory tow package with seven way trailer connector, part number 118271 on our 2014 Chevrolet Traverse.
