Review of the Roadmaster Universal Diode Wiring Kit


Hi there flat towers. Today, we're gonna be taking a look at Roadmaster's Diode Wiring Kit with flexible coil cable. When you flat tow your vehicle you need some way to take the lights that's on your motor home and make them visible here at the back of your vehicle. And there's a lot of different ways that you can do that. But it's important so that people behind know your intentions when going down the road. Cause this vehicle that you're pulling behind your motor home is likely obstructing some of the lights on your motor home.

So they may not be visible. So that's why it's important, they're back here. Roadmaster's Diode Wiring Kit is my personal favorite way to get lighting here at the back of the vehicle. It will take all the signals from your motor home. You just plug into the seven-way connector and it will transfer those signals, just like you would a trailer to the lights back here.

But the diodes act as a one way check valve that will allow those currents from our motor home to illuminate our lights but will not let it backfeed into the factory wiring here are on our vehicle. So that way it can't cause any damage to its components. Now some other options are like magnetic lights, there's bulb and socket and there are other manufacturers that make diodes but this is definitely one of the easiest ways. It's an economical solution and Roadmaster has done a very good job in providing a very durable kit. Let's go take a quick look at the front before we get into some of the other kits.

So in addition to the diodes and the wiring you need to get it installed on your vehicle. With this kit, you also get a flexible coiled cable. That is a seven-way on one side and a six-way on the other side. Six-way is the most common connector for the front of a flat tow setup on your vehicle. And seven-way is the most common at the back of your motor home.

So that way we can easily make our connection. The connector does come included with this kit. So that way you have your six-way connector here for your vehicle and you get a mounting bracket with it as well. And it really does come with everything you need to get the lights operating. So, now we're gonna go ahead and head to the back. I'm gonna pull down one of the Roadmaster diodes and we'll take a look at that diode in a little bit further detail and also compare it to some of the other manufacturers diodes. So, here I have the Roadmaster diodes. I went ahead and pulled them down from the location I had 'em secured to. And we can see the diodes have a very thick metal heat sink all the way around because these diodes, depending on the lighting that you have at the back of your vehicle, especially if you have incandescent lights on your vehicle there can be quite a bit of current that is running through these circuits to our lights here. And that heat sink, the metal heat sink on here with the fins helps to dissipate that heat, keeping it cool. So that way we can deliver the current we need without any interruptions or damaging our diodes or wiring or anything back here. They have adhesive backing on 'em as well. So you could stick it in place. This is a Jeep here, so we didn't want to just stick it on there. He probably does some off-roading, go through some creeks and stuff. So we're gonna use cable ties to secure it, but depending on the vehicle you're working on, if you don't put it through those rougher environments, the adhesive pads work out really nice that just come included with it. Here's another manufacturer's diodes. These are the ones from Demco that we offer here and you can see they're puny to the Roadmaster ones. They have a plastic outer shell. And I mean, it's nice potted, I guess it's all sealed up but so is the Roadmaster one. And the Roadmaster comes with, again, those really durable heat dissipation heat sinks on there and this has just got nothing on it. So the heat's just, hopefully can radiate the way it needs to where it's installed. There also is no adhesive pad or anything on these. So I just don't prefer these over the Roadmaster. They're just so much better with a harder metal shell that dissipates the heat. The sticker also clearly labels the in and the out on our Roadmaster ones. And it is molded into the plastic here but it can be difficult to see and it's only on one side. So for installation purposes, I just really prefer the Roadmaster for the durability of their diodes. They're just a little bit easier to work with and you get plenty of cable wire length as well as connectors to install everything with the Roadmaster kit. And while these are the ones from Demco, Blue Ox has some diodes that we offer here at etrailer and they're very similar to the Demco in their shape and size and style. So, I would still recommend the Roadmaster over those as well. So we've taken a look at a couple of the other manufacturers diode kits and by far Roadmaster's got the nicest diodes with those heat sinks but there are some other options besides diodes. So here I have magnetic lights. So if you didn't want to have to tap into the vehicle's existing wiring and install these. It is a little bit of an initial setup to get diodes installed. I mean, most vehicles it's gonna be somewhere between probably an hour and two hours of installation. Whereas these magnetic lights really don't have, hardly any installation. They simply just stick to the vehicle. Now you could see where, you had something like this Jeep here. You're not gonna be able to stick them on the roof because one, there is no roof. And two, if it had one it's likely a soft top that it's not gonna adhere to at the magnetic surface. But you could put 'em on the side, you know, they will still work on a lot of different vehicles. It'll stick to the side and that's still plenty close to illuminate and do what it needs to do. The problem with the magnetic lights though is, see this big jumbo of wires here. Well, you gotta undo this, run it up to the front and plug it into your motor home every single time you want a flat tow. With the diode wiring kit that we installed, it has a connector at the front and you just plug it in. So, hooking up and unhooking is extremely fast in comparison to magnetic lights with our diode kit. But again the installation process, so this is almost nothing. So I, if you're afraid of doing the install, if it's just not something you're into or if you just want something quick for, that you can move from vehicle to vehicle. Magnetic lights are an awesome option for multiple vehicles but if you're gonna be hooking up, and this is your main flat tow vehicle you're planning on for have for several years, I highly recommend the diodes to save you so much more time in the long run. And it's just a cleaner install. These things are gonna be sticking here on the side. Most of the magnetic lights do have a surface on bottom to prevent scratches and abrasions. But over time, this does get worn off and you could potentially get scratches. Whereas our diodes are just in there that heavy duty heat sinks gonna keep it working for many years to come. The last option is a bulb and socket kit, where you physically drill a hole into the assembly and add your own bulb that you will then illuminate using your motor home and run wiring up to. So it's a totally separate bulb. That's separate from your vehicle. That's just for lighting up when you're hooked to the motor home. And that's, to me, it's just as involved as an installation process as a diode kit but you have to modify your taillight assembly. And when you modify that and put a hole in it, you do seal it up but there's just another chance for leaks to occur in there which can damage your components if you do get a leak. The extra bulb that you install in there if it's an incandescent bulb but is gonna generate some heat. And if you have it close to certain components you could get deformations. And a lot of states do require safety inspections where moisture, if it does enter in there will fail a safety inspection. So I typically recommend to stay away from the bulb and socket kit as the labor is just as intensive as diodes and the results are just less pleasing. And oftentimes on these new vehicles that have LED lights, there's not room inside the assemblies to put a bulb in there anyway. So if you drill that hole and find out it doesn't fit you're in a real bad spot. Whereas our diode kit here works with basically any vehicle and we've got a lot of video content here at etrailer to show you how to install it on your specific vehicle. So you want to use our fit, guys, so you can find the most appropriate videos and parts for your vehicle. And that completes our look at Roadmaster's Diode Wiring Kit with flexible coiled cable..
