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 tha
