Today on the 2020 Jeep Grand Cherokee, we're going to be taking a look at and showing you how to install Roadmaster's Diode Wiring Kit. Here at eTrailer, we install, test fit, and review a lot of different products to help answer your questions and ensure proper fit. When flat towing your vehicle behind your motorhome, there's five main components you'll need to do so. First is our tow bar, which is our attachment between our motorhome and our vehicle. In addition to your tow bar, you'll need your safety cables, which is a supplemental attachment, in addition to your tow bar. You also need your base plate, which is the connection point on our vehicle that our tow bar is going to attach to. You also need your diode wiring, which takes all the lighting signals on your motorhome and transfers them to the lights on your vehicle so people will know your intentions when going down the road.And lastly, your supplemental braking system, which will take all of the brake inputs from your motorhome, send them to your vehicle, which will apply the brake inside your vehicle to help you come to a safe stop. These are available in a few different configurations. You can get just the diodes with wires, you can get the diodes with wires that also comes with your umbilical cable to connect your vehicle to your motorhome. And those are available in a couple of different configurations. You can get a coiled cable, a straight cable or a hybrid, which is partially straight and partially coiled. And that's going to vary on your tow bar, which one's going to work best for you.Our customer opted for the Nighthawk tow bar, which comes with your six way connector. So our customer purchased the kit that just has the four-pole ends on it, because we can just cut off those four pole ends and then adapt it to the six pole using the parts that came with this tow bar. Your diode wiring kit is going to take all the lighting signals from your motorhome and transfer them to the lights here at the back of the vehicle. The diodes ensure that the voltage can only be directed from the motorhome to our light. And they act as a one-way check valve, so that voltage can't back feed into the rest of our system and affect any of the wiring or computer systems on our vehicle. This is my preferred kit for getting lighting at the back of your vehicle. There are a couple of other options such as bulb and socket, which would require you to drill a hole inside your taillight assembly and add an additional bulb.That's a good option if you don't want to worry about voiding any warranty, because with the diodes, you do have to tap those into the wiring. Although I highly recommend the diodes over it because you have the potential chance for leaks down the road and stuff when you drill out and add the bulb. It does come with the stuff to seal it up, but over time it could definitely degrade.The last option is magnetic lights, which would stick on top of the roof and they just plug in right there at the front. They typically use a four-pole connector and this one of the quickest and easiest ones to get set up. You just got to pull them out, set them on top and you're good to go. But they're definitely one of the most unsightly and you have to set them up every single time. So even though it's easy, it's still extra work. With the diodes, you spend a little more time upfront getting the install done, but once it's done, you never have to worry about it again. You just plug in at the front of the motorhome and you're good to go.We'll begin our installation here at the front of the vehicle, by starting
