How to Install the Roadmaster Diode 7 to 6 Wire Coil Kit on a 2015 Smart fortwo


Speaker 1: Today on our 2015 smart fortwo you're gonna be taking a look at, I'm gonna show you install the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit. Part number RM-15267.This is what our Diode kit looks like when it's installed. Six bolt here at the front of my vehicle. What this is gonna do, this is gonna give me connection point between my RV and my towed vehicle, or my smart car while it's being flat-towed behind the RV. This is gonna allow me to run my lights through my RV.For instance, once my umbilical cord is plugged into here, and it's plugged into my RV, once I step on the brakes, it's gonna activate the brake lights, or signal in the car, or in the Smart Car, while it's being towed. Same thing goes with my running lights, and both my turn signals.This diode kit is gonna hook directly into your factory tail light wiring.

The route from your six pole, that you mount in the front of the vehicle, to the back of the vehicle, it'll split off an go to the driver's side, and passenger's side wiring.Now, on each side, you're gonna have two diodes. First side, and the diodes are gonna protect your factory wiring from any back-feed from your RV. If there happens to be a short, or a problem in the wiring somewhere. It's gonna protect your factory wiring in your towed vehicle.This diode kit is gonna be one of five main components in a flat-tow setup. The other four are gonna be your baseplate, your tow bar, your safety cables, and your braking system.Our six pole plug, here, it's gonna have a spring loaded lid.

It will stay closed to help keep any moisture or debris off of the pins inside the plug. Now, your diode kit is only gonna be four wires. So, you're gonna have two extra pegs for any other accessories you may want to add on. For instance, like a battery charge line kit.Now, as far as the insulation goes, it is a fairly straight forward, pretty simple installation. You're gonna have a six pole plug that you're gonna mount somewhere in the front of the vehicle, you're gonna have about 30 feet of wire, you're gonna route to the back, whether it be underneath the vehicle, or through the interior of the vehicle.

Which is gonna tie into both tail lights with a couple of diodes.Now that we've gone over some of the features, let me show you just how easy it is to put in.This is what you're gonna get in your diode kit. You have your plexy coil, your umbilical cord that's gonna go from your towed vehicle to your RV. You're gonna have your four-pole wiring, for your wiring that's gonna go to your plug on your towed vehicle. Your diodes, and your six-pole plug. You're also gonna have a mounting bracket.

Now, depending on where you decide to mount this, you may need an extra bracket to get this mounted correctly.First thing I need to do, is I need to get one end of this wire, from the front of the car, to the back of the car to my tail light wiring. Now, there's a few different ways you can do it. You can go underneath the car to the back, feed it up both sides to your tail lights. You can run it through the car. There's actually a grommet right here, that comes out right underneath the dash. I'm probably gonna go that way. I'll just run it through there and then run it underneath the carpeting to the back. I can split it, because my wiring for both tail lights are right inside the panel on each side of the vehicle. So, I really don't need to be outside the vehicle with my wiring at all. I think it's gonna be easier to go that way.So, you can see where I came through the grommet there, very easy to get to inside. It's fairly easy to get to out here. What I need to do, is I'm gonna take a little bit of this, and I want to coil it up, this is a small car, so we're gonna have quite a bit of wire left over. I'm actually gonna coil up about like that. I'll just zip tie it, leave it hang here for now. Then we'll figure out where I'm gonna put my plug later. But, I'm gonna need some extra wire if I do a brake system, I'm gonna have to tie into it. So, I want to make sure I have enough that I got easy room to work.Now, what I'm gonna do with my wire, is I'm just gonna run it right underneath my edge of my carpet here. I may go on the edge here, I may try to feed it underneath my seat. And then try to come out toward the center behind these two seats here. So, just pull it up like this, and tuck it in there. You can do that all the way to the back.Once I got past the driver's seat, tucking it underneath the carpet, what I did is I just came up and went around the backside of the seat here, underneath the carpet, and I came right up this side. You can see how I got it ran. So, now I'll be able to run my wires right underneath this panel, and then I'll have two wires I'm gonna run across, and I can just lay them right in here, run up underneath that panel.Next thing we need to do is we need to separate our wires. I'm actually gonna strip these back pretty far. I decided what I'm gonna do instead of running my wire here, across to the other side, I'm actually gonna take it, I'm gonna tuck it right here. I'm gonna go ahead and remove the two fasteners. I have a tie-down loop right here. I'll be using a star bit to remove that. We'll be using a T-45. Then over on this side, there could be a plastic fastener, you just turn it, it kind of unscrews out of there.I'm gonna remove this loop here. It's gonna make it a little bit easier to get up in there. You can see, I've got my green and my brown wire left over here. I'm gonna go ahead, re-install my tie-down here. That way it keeps my wires tucked in there.I'm gonna go ahead and remove my panels from my driver and passenger side. You can see it has two releases, one here, one over here for the driver's side.At this point, I'm just gonna take my yellow wire, go right underneath the panel here. Just pull on this like that. Leave our white wire there. Come over to our passenger side. And my green and my brown wire, I'm gonna feed it behind the panel.Now you can see all my wires hidden. Got my green and my brown wire. Coming up through my panel here.The next thing you need to do is you need to test to determine which wires are for your signals. We've determined that our gray and green, and our black and green are gonna be our signals. Now, this is gonna be a combined system, so all our turn signals, and our stop light is gonna be for the black and green, and then our tail lights are gonna be for the gray and green. So, those are the two wires that I'm gonna be adding my diodes onto. In order to do this a little bit easier. I'm gonna go ahead and pull the plug out of the light socket, like this. And all's your gonna do, is on each side, you're just gonna pinch and pull it out.So, the first one we're gonna do is gonna be our tail light. Which is gonna be our brown wire coming off of our wiring that we ran back here. This is gonna be our gray and green, cut that wire like that, and we're gonna strip back, I would suggest stripping back just a little extra. These wires are a little thin. We're gonna take this one, it's got the one yellow connector on it, and we're gonna connect to one of our ends here, to one side of our wire. I'm gonna add the other one to the other side of the wire. This will go like this. Then for this one, we're gonna add on our brown wire. So, I'm actually gonna strip back one end here, and then the other part that I just cut off, I'm actually gonna strip off a little bit from there, like this. We're gonna put them together, and we're gonna put both of them inside of the yellow. Crimp them down. Make sure you've got a good hold. Then that's gonna be there.So, what did there, is I made myself a jumper. What I'm gonna do is I'm gonna take my brown wire now, and I'm gonna route it under and across and hook it right into that side.Now, I'm gonna do my turn signal and stop lamp, since they're combined. We're gonna be using the green wire. We're gonna repeat the same process here. Then four. This is gonna go like this. And then for this one, we do our green wire. Again, give yourself plenty. The only thing with this one is we're not gonna combining it with anything. It's gonna go directly into our butt connector, spayed connector here, and then plugged directly into the diode.Now, we can plug our tail light back in. What I'm gonna do, I'm gonna actually stick these together, like this. We're gonna be inside the vehicle. I'm gonna try to stick them back in here. This has got double sided tape on it, we'll peel this back, stick one on top of the other.I've got a bit pocket right in here, it's open, so, it's just a matter of getting my wires moved around enough, where I can stick it in there. Peel this off. Feed that down there.You can see, I just stuck it right to the inside of this pocket here, right against the wall. What I want to do, is I want to route this over here, so I can connect it to my wire. So, I can either run it across here, or I can run it around. It's dependent on whatever you want to do. I'm gonna try to, without taking this out again, try and get it around that, so I can get it over here. If I have too much trouble, I can always just run it across here too. It's completely up to you.You can see I routed my brown wire up behind my panel with my yellow wire. My white wire, is going to be my ground, and what's nice about it is I actually have a bolt right here, that is connecting all my ground wires to the body. So, all's I'm gonna do, I'm gonna add my ring terminal, take the nut off, put it on there, and add my nut back on.So, I'm gonna give myself a little bit extra so I can actually tuck my ground wire up behind the panel here. I'm gonna cut it about here. Strip it back. Add the ring terminal that comes in your kit. Crimp it into place. Make sure you've got a good hold. And we'll take a 10mm socket, go ahead and remove our nut, go ahead and add your ring terminal, and replace the nut. Just like that.So, we determined, through testing, on our driver's side, our brown wire with the gray stripe is gonna be our tail lights, which our jumper wire that we ran from the passenger side, we're gonna tie in with that diode. And then our black wire with the white stripe, is gonna be our stop light, and our turn signal. So, we're gonna be tying our yellow wire into that one. We're gonna connect them just the same way we did on our other side.So, what we're gonna do for this side, is you can see how it has an in and out. The single wire is going, or the single side out, is going to the light, and the side with the two on it, is going to your factory wiring your vehicle. Our brown wire that we got coming from the other side, instead of tying it to one of them, it's actually gonna be going into it's own connector.So, we'll cut this down, and leave yourself a little bit extra so you can move it around. Crimp it down. We're gonna add that, just like that. Now we'll do the same thing with our black and white wire, and our turn signals.Once you get all your wires, tucked in, nice and neat, you can go ahead and replace your panels. Replace your panels. Now we can move to the front of the vehicle.So, how I'm gonna do my wiring is this comes in your kit. This is to hold your six pole plug. If I mount it here, it's gonna sit right behind the license plate. So, I took a short bracket, part number 18144, and I bent it. You can kind of see how I bent it there. I'm actually gonna mount it like that, and this is gonna sit down on the bottom like this. And it'll be just in line with my baseplate here.So, I tried a self tightening screw here, and it wouldn't work. What I did, I just widened the hole a little bit, and I'm putting a nut and bolt through it. Because the whole inside of this bumper core right here, is all hollow, so I can reach back there and get a wrench on it. It doesn't matter what size you use. Just make sure it's big enough it's gonna hold it. And you're gonna want to drill out to whatever size you have. I'm gonna use an 11mm socket for the one that I have, and wrench to tighten it into place.My six pole bracket. Now, I'm just test fitting it right now. I'm gonna have to pull it back off when I go to put my fascia back on.So, you can see how my bracket comes through my fascia, and it's cut out enough to where I can get this top part of my bracket through, or this short bracket through. I added my six pole bracket that comes in my kit. Now, we can mount it two different ways. You can mount it like this, or you can spin it around and mount it. We're gonna have to cut out the hole for our six pole plug, which is gonna be there. I actually, just considered just mounting it like this, because the license plates comes right down over is bracket, and then with my plug, we'll actually be sitting under my license plate like this. As long as I can open my lid, I'm gonna mount it like that. If not, I'll just flip this bracket around and mount it the other way. But, for right now, I'm gonna go ahead and use this as my template so that I can cut this out.I'm just gonna use, you can use wire cutters, this grill is not that thick, so it cuts pretty easy. It should, we can mount this on here. And put the plug in.I'm gonna take my six pole plug, and no matter how you try to mount it, you can do it like that if you want. I'm actually gonna try it the other way. I like how it sits flush with the grill. It's gonna come with a couple of screws and nuts to mount it to the bracket here.Next thing I need to do is strip back my wires. We're gonna take the back of our plug, and the back of our plug actually tells us what's what. Right turn, left turn, ground, and TM is gonna be our running lights. Take a small fillips or flat head screw driver, you don't need to take these all the way out, they are small, and you will lose them.Next, we want to make sure we put our boot on. We're gonna do skinny side first over our wires. Just kind of leave it like that, then we can start connecting all of our wires. Green, for right turn. Yellow, left turn. White, ground. And finally, brown for our running lights. Take our boot slide it all the way to the top like that. You get some wire loom in your kit. I'm gonna use a little bit around my wires here. Just so you can't see them through the grill.What I'm gonna do, is I'm actually going to start right here on this boot, I'm actually gonna tape it closed. That way it stays on, kind of protects it from any water or anything getting in there. Then we can mount our bracket into place.Your kit is not gonna come with these screws, you can use anything that's gonna fit through the hole to hold it in place. I think I'm gonna go up like this. You can take a fillips or flat head screwdriver, a larger one. Get those tightened into place.Now, with an alternate power source, we're gonna test out our lights. This is gonna simulate being hooked up to your RV in flat-towing your vehicle.Tail lights. Left turn. Brake lights. Right turn.That'll do it for a look at an installation on the Roadmaster Diode 7-Wire to 6-Wire Flexo-Coil Wiring Kit, Part Number RM-15267, on our 2015 smart fortwo.
