How to Install the Roadmaster Diode 7 to 6 Wire Coil Kit on a 2019 Chevrolet Colorado


Ryan: How's it going Ryan here at etrailer.com. Today on our 2019 Chevrolet Colorado, we're going to be taking a look at and showing you how to install the Roadmaster Diode Wiring Kit. This is going to allow you to transfer the lighting signals from the back of your motorhome, to the back of the Colorado. That way you'll be safe and legal as you flat tow your Colorado down the road. What I really like about these compared to some of the others is the fact that once we get them installed, all we have to do to use them is plug them in, compared to some of the other ones where we have to drill into our tail light housing, or the magnetic style. For example, we have wires hanging, we have to set it up every time, and we have to worry about those magnets scratching up our truck's paint.Our diodes are actually going to separate our new wiring from our factory wiring.

And that's especially useful in the case of a short or something like that. It's going to protect our factory wiring from any type of damage. Now, one of the things I really like about the kit is that it's going to come with a bracket to bolt your plug too, which is also included as well as a coiled wire to connect to your motorhome. And that's everything you're going to need to get your Colorado all hooked up. Now, there is one more thing that I personally used and it's a long bracket which can be found here at etrailer.

And the reason I use that was to help pull our connector or our plug rather, flush with the bumper. So if you want to set it up like this, that's one thing you're probably going to need to pick up.And since the cord is coiled, whenever you turn, it's going to stretch out. Whenever you get back to normal, it's going to get smaller. That way, you're not going to have to worry about it dragging on the ground. Now, putting together a flat tow setup can be a little bit overwhelming, but keep in mind, there's only five main components.

You're going to have your base plate, your tow bar, your diode wiring, your braking system, and your safety cables. Now getting your wiring installed can be a little time consuming, but as long as you take your time, you shouldn't have any problems. Speaking of which, let's go ahead and do that together now. To begin our installation, our fascia is removed and that's because we did a base plate earlier and decided to do the wiring now, but it's still out of the way because we will have a lot more room. We're going to need to first route our wiring from the front of the vehicle, where we want our connection point to be, all the way to the back by the tail lights.Oh, here's the path that I took and just ran it along our bumper beam, then up along the side of our radiator, that little pocket, and pushed it into the engine compartment.

And this came along through here, and towards the back here, I actually dropped that wiring down next to our frame rail. So here's where our wiring drops down, and I dropped it on the outside of the frame rail. That way we're sure to avoid any hot or moving parts. And just dropped it down over our body mount, and then I just followed this factory wiring all the way down the side. Once I got to about this point, I ran the wire over our frame rail to the inside of our truck. And here's where our wire outcomes on the inside of our frame rail. Once again, I just followed that factory wiring and up and over our metal brace and a little bit right passes by the tire inaudible 00:03:54 again to the outside of the inaudible 00:03:56 wheel secured it using a zip tie up here.And now since our wiring is right by our tail lights, all we can do is go up to the back of our truck and get started on those. Now, if you come back here to our tail light, we're going to need to remove it. So we're going to have two screws, one here, and one here, we'll take those out using a t15 Torx bit. Then once we have those screws out, we can kind of put some pressure towards us, on our tail light to pop it out. And if you flip it around, you'll see all of our bulbs. We'll just take these out that way. We can set our tail light off to the side. So you'll just spin these, about a quarter of a turn, you'll just pull out. A little clip there, just rest those down there and set our light off to the side. Now, just a quick tech tip, these alignment pins here can get kind of hung up and yet, if they come out completely like this, it's no big deal. You're just going to have to put a little more tension on the tail light when you go to remove it. But once this one is disconnected and set off to the side, you can repeat that same process over on the passenger side.So back now underneath the truck to our wiring, what we're going to do is separate our four wires from each other, and then we can run them up into our tail light. So I'll just take a pair of snips and kind of carefully cut in between each wire. Then we're able to peel them apart from each other. Now I'm just going to peel these all the way back as far as I can. So with all of our wires separated, then we just twisted the ends of them together, and then we can feed it up into that opening that goes to our tail light pocket. Now with our wires ran up through the taillight pocket, we can test our factory tail light wiring to find the tail light or running light signal. Now I'm going to be tapping into the bulb closest to the top of the truck. So with the tail lights on, go ahead and use our test light to find the signal and we'll start with this orange wire. So when we propagate, you can see that it's lighting up and making noise. So we've identified our taillight signal.So I went ahead and turned on our left blinker and we can find the turn signal wire. So go ahead and check this gray wire. And it's flashing with the turn signal, so we know that's it. Now we can focus on hooking up or diodes. So we'll go ahead and take our gray wire and our orange wire and cut those in half. We're going to strip each end back to expose the wiring underneath that insulation. I kind of like to twist the wires together, to keep them nice and tight. Do that on both ends. What we're going to do is take the blue terminals off of our diodes and connect those to each end of our wire. So we'll go ahead and slide that over it and we'll just crimp it down. Now we can plug our diodes in. I like to use some dielectric grease on the terminals just to help keep them a little more protected. We're going to spread that on there, we're to take the end that says out with a single terminal and plug that into the orange wire closest to the bulb.The other end of the orange wire will go on one of the end terminals. Now we're going to hook up our brown wire. So we'll kind of measure this out to length, and cut that. And what we're going to do is take the other end of the brown wire that we just trimmed and strip that back as well. We're just going to connect those two together. With them to connect together, we can grab the yellow terminal, slide that over both of them, crimp it down and put that onto the last remaining terminal on our diode. Now for the other one, we're going to take our diode, again, put some of that dielectric grease on, flood the single out post with the gray wire, closest to the bulb. Take the other end of the gray wire, put it on one of the end terminals. We're going to take our yellow wire, cut it to length, put it on one of the blue terminals, once you have it crimped down. And that one will finally plug onto that last remaining terminal. Just like that.Now what we're going to do is take our diodes and secure them together. So on the back side will be some sticky tape, just peel that backing paper off, we'll just line them up nice and straight, and push them together. Now we can reinstall our tail light. However, I do want to point out our green and white wire that we ran up earlier, this is actually going to get routed over to the passenger side of the vehicle. So we'll just go ahead and push those back down through the underside of our truck. So the bulbs will get installed in the same way into the tail light, just kind of push them in. Once they fall down, we're going to spin them a quarter turn. Line everything back up, and resecure the tail light. Now we can take our white wire and find a place to ground it. Now I'm going to choose right here as long as it's a solid clean piece of metal, it should be all right. We'll go ahead and do this, kind of cut off that extra wire and just strip back the insulation, take the included ring terminal, get that crimped onto the wire and then I'll take the included self inaudible 00:11:19 texture and use that to secure it to our frame.Make sure it's nice and snug, and we're good to go. I went ahead and routed our green and brown wire over to the passenger side tail light. That's the path that I took. You'll see some zip ties along the way to keep it secured. So here's where our two wires ran up just like the driver's side. And now at this point we can start to connect our diodes. Same thing, we're going to be using this bulb closest to the top. And I went ahead and tested the wiring. We're going to be using the gray wire as well as the orange wire. Once all those are crimped on, we'll go ahead and take one of our diodes. What we're going to do is take the single one that says out, put that into the orange wire closest to the bulb, and connect the other end of the orange wire to one of the terminals that say in.Now, the brown wire is what we're going to connect to the style. Grab our other diode single terminal that says out, plug into the gray wire close to the ball. Then the other end of the gray wire, one of the end terminals. And finally, we're able to get our green wire set up plugin to that last remaining terminal. I'll just go ahead and get it reinstalled and secure. Now, at this point, we can hook up our plug and our mounting bracket. However, I did find our mounting bracket is kind of short. So I actually used here, a No-Drill Long Bracket, then I was able to connect to our bumper beam, that way it'll give us some distance and we can mount everything where it's easily accessible. Now, we can take our rubber grommet and run our wiring through it first. And if you're wondering what this red wire is, our customer is installing a charge line kit. So it makes sense to do this right now at the same time.We'll go ahead and take the bracket, put that over the wires as well. And now we can peel back the insulation to expose the wire underneath. Now we can take our plug and get our wires hooked up to it. Now, there is some lettering that lets us know which wire goes where. We'll have LT for left turn, and that'll be our yellow wire, RT for right turn, that'll be our green wire, TM and that'll be for our tail lights which will be the brown wire. GD is going to be ground for our white wire. And the one in the center here will be for our red charge line. So the way these work is, these little set screws, we'll have to loosen them up a little bit. Then you'll take the corresponding wire, which in this case, we're working on the LT. So we'll grab our yellow wire, we push that wire all the way down into place. Let me simply just tighten up that set screw. I'm going to repeat that same process for the remaining wires.What I like to do is take some dielectric grease and just really cover those terminals with it, to help keep them protected from any corrosion. We can go ahead and slide our bracket over as well as our rubber cap. What I like to do is just take a little bit of electrical tape and kind of tape around that just to help keep any moisture out of there. So I went ahead and secured our plug to our bracketry, get it nice and solid. Now we can go ahead and test it to make sure everything's working correctly. So I went ahead and plugged everything into our tester. And if you don't have one of these, you could always just use your motorhome. And so now we can go ahead and turn it on to make sure our tail lights are working. Our left turn, our right turn, and finally our brake lights. And that'll finish up our look at and our installation of the Roadmaster Diode Wiring Kit on our 2019 Chevrolet, Colorado..
