Diode kit lets you wire your vehicle to accept the brake and turn signals from your RV for flat towing, all while preventing feedback from your RV. Wires 2-wire and 3-wire systems to operate as a combined lighting system.


  • Lets you wire your vehicle to accept your RV's tail, brake, and turn signal lights for flat towing
  • Wires towed car as combined system so that brake and turn signals travel along same wire
  • Prevents electrical feedback and the damage it can cause to your vehicle's electrical components
  • Heat-sealed casing protects diodes from the elements
  • Includes:
    • 4-Wire harness
    • 4 Diodes
    • 12 Wire connectors

Note: For applications that have separate lighting, this kit will cause your brake lights to function as both brake and turn signal lights. A wiring converter (118158 - sold separately) and 2 additional diodes will be needed if you want to retain separate turn and brake signals.

Separate vs. Combined Lighting Systems

Some automobiles operate on a 3-wire system, wherein the brake signal and the turn signals travel along different wires to illuminate different lights. (Typically, these vehicles have amber turn signals.) This is referred to as a "separate lighting system." When you hook up for flat towing using this kit, your towed car's lighting system will operate in a combined fashion regardless of whether it typically has combined or separate lighting. This means that the brake and turn signals sent by your RV to your towed car will be carried on a single wire. As a result, your car's brake lights will do the flashing for the turn signals. Your vehicle will still function as designed when not hooked up to your RV.

Do You Need a Brake Light Relay?

Because this kit wires your vehicle as a combined system, a brake light relay (sold separately) may be required if you use a supplemental braking system with your towing setup. A supplemental braking system depresses the brake pedal in your towed car every time you apply the brakes in your RV. So, if your towed car's brake lights illuminate when the brake pedal is pressed and the engine is off - as is the case when towing - then you need to install a relay to ensure that the lights on your towed car always act in accordance with the signals sent by your RV via the wiring harness. Without a relay, the brake signal from your towed car will override the turn signal sent by your RV when you slow down to make turns, creating a potential hazard.

Video Transcript for Demco 4-Diode Universal Towed Vehicle Wiring Kit Installation - 2017 Jeep Wrangler Unlimited

Hey everybody, Ryan here at etrailer. Today on our 2017 Jeep Wrangler Unlimited, we're gonna be taking a look at and showing you how to install the Demco Diode Wiring Kit for towed vehicles. So there is gonna be two different kits available. The one we have here has a six-way round connector and a cable that allows you to plug into the seven-way in the back of your motorhome. The other kit doesn't it come with this cable or the connector, just has a four-way flat type connector so if your motorhome has a four-way flat, you're able to just plug that right in. So there's gonna be a total of five main components needed to flat tow your Wrangler down the road safely.

First one's gonna be the base plate and that's gonna provide us with a solid and reliable connection point. That way we can hook our tow bar up to it. So the tow bar here is gonna be your second main component. This is gonna be the physical link that actually connects the front of your Jeep to the back of your motorhome. The third main component is going to be safety cables.

And these are gonna be there in the event of an unlikely disconnect. These are gonna keep your Jeep connected to your motorhome. The fourth main component is going to be tow bar wiring. And this wiring, what it's gonna do is transfer the lighting functions from the back of your RV to the back of your Wrangler, keeping you safe and legal. And last but not least, our fifth main component is going to be a braking system.

And now what that's gonna do is apply the brakes in your Wrangler whenever you hit the brakes in your motorhome, helping to bring you to a more predictable and safe stop. So this is a perfect example on how our wiring is going to work. As you can see, we have the left turn signal going on our motorhome, and it's transferring it back here to the Jeep. But you're also gonna get your right turn, your brake lights, and your running lights. So you'll have all your bases covered there.

Now, when it comes to tow bar wiring, a diode wiring kit like this is definitely the way to go in my opinion. Once you have it installed, you're not gonna be able to see it and it's gonna be super easy to use, which is really important. You don't want to spend a bunch of time messing around, setting everything up when you're trying to hit the road or enjoy yourself. With this one, all you're gonna have to do is plug in a connector at the front of your Jeep to the back of your motorhome. And that's really all there is to it. In comparison to some of the other kits like magnetic lighting, for example, those are gonna require you to set them up and remove them every single time. So, you're gonna have to find a spot to put your lights, take the wiring, drape it all the way over your Jeep to the front of it and set it up every time. And then, not to mention, when you are ready to disconnect, you're gonna have to take that big bundle of wire and find somewhere to store it. So, a set up like this definitely makes life a little bit easier. This kit also uses diodes and what those are gonna do is protect your jeeps factory wiring if a short or some type of an electrical issue we're to happen, so pretty important. Especially today's newer vehicles, they have a really sophisticated electronic systems. Everything's kind of tied in to everything else. So definitely don't want to do anything to jeopardize that. And since we have those diodes in place, it's something we're not gonna have to worry about. So, at the end of the day, if you're gonna be flat towing quite a bit, definitely the way to go, super easy to use. One thing I do like, comparison to some other kits, is a connector. If your out for this kit here that comes with the cable and the connector. The connector itself is made from aluminum. Typically, they're made from plastics. I feel like that aluminum will just hold up better. But overall, the kit feels really nice. All the wiring is nice and thick. Everything's just well-made. As far as the installation goes, really not too bad or it's not really super complicated. It's just kinda time consuming, you know Having to route all the wires and everything else. But as long as you stay focused, shouldn't really give you a whole lot of issues. You need a winch Let's go ahead and pull into the shop and do that together now. Now to begin our installation, we're going to be here at the front of our Jeep and I took our bundle of wire and just took one end of it and ran it up through our mounting bracket. Now, if you're going to be using the kit that has just this four-way end, all you're going to have to do is mount that up here at the front and route your wiring back. In our case for putting on the six-way connector plug. So what we're going to have to do is cut our four-way flat connector off. So I'll grab a pair of snips. Cut it back as close as we can, give us all that wiring. Once that's removed, you can strip back the insulation from each one of our wires. Once we have these stripped, we can grab the dust cover, slide that over, just kind of push it out of the way for now. Then I'm going to twist each one of these wires nice and tight, and that'll help ensure a good connection. And then we can move on and grab our connector plug here. So the way this is going to work, the terminals are going to be labeled and they're going to have set screws in them that we need to loosen up. So for example, we'll start with this one here. That's labeled TM for tail lights, our brown wire, will go to it. This one here is GD for ground. White wire will go there. This one's LT for left turn, so our yellow wire will go to that. And this one here, so we have RT for right turn, so our green wire will go there. So you take the flathead screwdriver, back out the set screws a little bit. And what you're going to do is take the corresponding wire. So we're gonna start with tail lights, so that'll be the brown wire. That'll just get put into the terminal. The wire sticks out a little bit. If you cut them too long, what I like to do is just trim it. I like the whole wire to be inside there, that way don't create any weak spots or anything like that over time. So pop that in there and tighten down our set screw. Now do the same process for our three remaining wires. So this is what the back of your connector plug is going to look like once you have the wires hooked up. And from there we can plug it, push it onto our bracket. You want to make sure to take your rubber dust cover, slide that over the back of the plug. That'll keep it protected. And I'm just going to take some hardware here and secure the connector plug to our bracket. This point we can start to route our wiring towards the back of our Jeep. Since the braking system that this Jeep is getting does require to be tapped into our diode wiring, I'm going to run this up into the engine compartment to make that a little easier. So what I've done is just cut off the four-way flat connector off the other end of our bundle of wire, dropped down a fish wire, which I'm just using a piece of tubing. Can use a coat hanger or something like that, and drop it down from the engine compartment. Taped my wire to it. Now we can go up top and feed our wire up into that engine compartment. So now in the engine compartment, here's where our wiring came up and then I just went around this edge then across the firewall, just following this factory wire loom all the way over to the other side. And right here, I dropped it straight down to the bottom side of our Jeep. So here's where our wiring kind of comes down under our vehicle. And right here in this area, just kind of underneath of our front door, I took the white wire and cut it in half very carefully. This side that goes to the front of our connector plug, in the connector plug up front rather, I stripped back the installation and I'm going to take one of the included ring terminals, slide that over the bare end of the wire and crimp it down. And this is going to be a ground. I got that attached. You want to secure this to a metal portion of our vehicle. And so I think I'm just going to go right here in this area. The feels nice and thick. Easy included self-tapping screw. So once that's secure, you want to take the remainder of your white wire and just strip that back off of the rest of the bundle. And you want to hold onto this portion of wire because we will be using it here in a moment. So I continue to route our wiring. So right here is where it comes over our frame rail from where we just attach that ground. So our wires, they run along through here and it's a little tricky to see, but it's kind of up on top of our frame rail almost. And when you're doing this, try your best to avoid any hot or moving parts. As long as it's not right on top of the exhaust and you got some good space there you'll be all right. Let's secure it along the way using some zip ties. I came up there here and up and over our rear subframe. It comes all the way over and drops down here. So over here on the driver's side, what I did was kind of just pull our green wire off of the yellow and brown and I took that white wire that we saved and just taped the end of it to our yellow and brown. From there, I took the other end of our white wire and our green wire and routed that over to the passenger side. So there's our green wire and our white wire, just ran it along the back of our bumper beam here, up and over our frame rail. And we can go up top, get our tail lights removed, that way we can put our wiring into position. So now here at the back of her Jeep, what we need to do is remove our tail lights. So to do that these inside screws are going to be some Phillips heads. We just need to pull those out. We should be able to grab our light and maneuver it around, get it pulled out. And then what we're going to do is just disconnect it, push down from that center tab, pull the two apart. And what we can do is just simply repeat the same process over on the other side. So I went ahead and just reached down, grabbed our wires and pulled them up into the tail light pocket, cut them to length, because the wire was a little long. And then I stripped back all the ends of the installation there. Our yellow wire's gonna receive a spade connector here. We'll slide that over and crimp it down. And what we're going to do with the white and brown wire, we're actually going to twist these together nice and tight. This end here, we're gonna put that in one spade connector. Get that crimped. Then we can go ahead and grab our diodes. And the side that has two labeled N, one of the spade terminals can you all on one side. Yellow one will go another diode. Now we can kind of just let these hang for the time being. So I went ahead and identified our signals here from our factory wiring and what I found was that the tail light signal is going to be this white wire with the orange stripe. And our stop and turn signal, we're going to use this white wire with the green stripe. So what we're going to do is cut those wires in half like so, and each end, we're going to grab our wire strippers, strip back the ends of the installation. And then we can grab one of the red or purple terminals there, slide that over the end, and crimp it down. So I'm going to repeat that same process for our three remaining ends there. Now that we have the ends all crimped on, we can hook them up to our diodes. So we'll start with our stop and turn. So that'll be the dial that has a new yellow wire. And since the white and green factory wires control it, we're just going to hook up one side to our diode terminal there. And the white and green wire that's closest to the plug, that's going to go on the side that has one terminal labeled out. Plug that in. And essentially do the same thing for our tail light signal, white and orange, closest to the plug we'll go to out. And the white and orange on the other side, will just get plugged into the last remaining terminal on our diode. Now that we have everything hooked up, go ahead, take our tail light, get that plug back in. We can just take tail light and reinstall it. Over here on the passenger side, I went ahead and hooked up our diodes pretty much the same exact way that we did the other side. The only difference is going to be the color of factory wires. So the white wire with a yellow stripe, that's going to be our stop and turn. So your new green wire will get plugged into that. And the factory wire with the white with a purple stripe, that's going to be your tail light signal, so the new white wire will get plugged into that diode. So once you have them hooked up, this point we just go ahead and take our light and get this re-installed as well. So now that everything is hooked up, it's a good idea to test our wiring to make sure it's working properly. So I went ahead and plugged into a tester box. Now you can use your motorhome, but keep in mind if you have any electrical issues going on there, this could give you a false reading, so I suggest using a box. That being said, we'll turn on our tail lights, our left turn signal, our right turn signal, and our brakes. And that'll finish up our look at and our installation of the Demco Diode Wiring Kit for towed vehicles on our 2017 Jeep Wrangler unlimited..

Great product, but you need to be handy, and have some technical knowledge.


What I expected. Wish the harness had been two feet longer (installed on JLUR). The installation video one was a good resource. Worked as advertised.


Plug and play, pretty much, product works and is still working! Thanks.

  • Troubleshooting Right Brake Light Coming On when Left Blinker Activated on Flat Towed Vehicle
    I would start by checking your ground wire on the motorhome and on the vehicle side of the Roadmaster # RM-15267, since that's the root of a lot of issues we see and should at least resolve the issue with the license plate light, but there's a lot going on here. I will also say that the diodes are not wire specific, meaning they can be used on any wire. To have the right brake light come on when the left blinker comes on is rather odd, since they should be on completely different circuits....
