Hey everybody, Ryan here at etrailer. Today, we're gonna be taking a look at and showing you how to install the Tekonsha ZCI Vehicle Wiring Harness, on our 2014 Mercedes-Benz GL-Class. So, there's something that is pretty cool about this setup, is the fact that we can store our wiring inside. That way when we're not using it, it's not gonna be out in the elements and you're not gonna be able to notice it. So whenever you are ready to use it, you can open up your storage latch there, drape it out over the bumper and hook up to your trailer. Now, this is designed to be closed in that hatch, so you're not gonna have to worry about damaging it or anything, as long as you're on the weather stripping and away from the latch.

But probably, the coolest thing about this kit, is a fact that you're not gonna have to actually cut or splice into your Mercedes wiring. Because honestly, with a vehicle like this, that's probably one of the last things that you wanna do, is start chopping into wires on a vehicle like this, and with the setup, you're not gonna have to worry about that. And that's because, at the end of the wires on our kit, the way it picks up those signals, our brake lights, tail lights and turn lights, is it just uses a clip that more or less a snaps around that wire and gets a signal that way. So, you're not hacking into it or puncturing that wire in any way. So, what's nice is whenever you close your hatch, it's gonna give us plenty of length.

Hangs down, right next where your hitch should be and will allow us to hook up to that trailer. So this is just a standard four way flat type connector, super common it'll work with a lot of different trailers, and one thing about this kit is it's really well-built. I'm a big fan Tekonsha, actually have a Tekonsha wiring kit on my own vehicles so I've got faith in them. And so you should have confidence knowing that this will last a very long time, but other than that it's gonna be a great solution to be able to power up your trailer, that way the lights work and you'll be safe and legal. Now, as far as the installation goes you may be thinking Mercedes-Benz probably complicated, and actually that really wasn't the case.

Everything's pretty easy to get to you don't have to remove a ton of stuff. The wires are easy to find and everything like that I will say probably the most challenging part or most time consuming part at least is having to run the power wire from the back up into the engine compartment. But as long as you take your time really shouldn't give you a whole lot of issues. Speaking of which let's go ahead and put this all together now. To begin our install, we're gonna be here at the back of our Mercedes and we need to gain access to the back of it.

So we'll open up our hatch and then we're just gonna have a couple of panels that we need to remove that way we can gain access to the back of our taillights. So if we look at this side panel here we can remove that it's just more or less just gonna pop out. You can kinda grab it there in the middle, pull this in and out first, pull it straight up, and set that off to the side and that'll give us access to our taillights. Now the passenger side of our vehicle is set up the exact same way so you'd simply pull that panel out from over there as well. Now we need to do is remove our threshold here and we're gonna have one Torx spit fastener on each side of it, so if you lift up your four covering you will be able to see the fastener. It's a T30 Torx bit, so once I pull this one out we'll pull the one on the other side out as well. So now if you grab your threshold you can kinda loosen it up and if it doesn't just pop right off one thing you can do is get a trim tool like this. It's kinda like a little plastic pry bar more or less and get it underneath the edge. There's some plastic push pin fasteners that are holding this thing in place. So you kinda just work your way down and free them. If you flip it over you can see that's what they look like, that's what we're releasing. Well with this free we can go ahead and set it off to the side out of the way for now. What I went ahead and did was take our wiring, and I grabbed the connector that said left turn, and I went in through that opening here on the passenger side gonna appeal back my carpet, and push that connec
