How to Install the Roadmaster Flexo-Coil Kit on a 2019 Chevrolet Equinox


Rob: Hey everybody. Rob here at etrailer.com, and today we're going to be taking a look at the Roadmaster Flexo-Coil Wiring Kit on our 2019 Chevrolet Equinox. Now, whenever you're going to flat-tow your Equinox behind your motorhome, you need a way to get those light signals to the back. Now, a lot of diode kits aren't going to come with an umbilical cord or the socket, that's where our Flexo Kit is going to help us out because we're going to be able to transfer the signals from our motorhome through the cord into the six-way plug on our vehicle that's tied into our tow bar wiring, that way, when we're driving down the road, if we need to change lanes, the motorhome signals are going to mirror what's on our Equinox so that everybody around us knows what's going on and we can be safe traveling down the road.I really like this style cord because it is coiled, so whenever we have it hooked up all the way, we'll still have enough slack for it to stretch when we go around turns, but at the same time, you can see it's going to retract back and it's going to keep all that slack from dragging the ground. On one end of the cord, we're going to have our seven-way connector, this is going to be pretty standard for most RVs and it's still going to have that little latch on there to make sure that it catches the door so it won't get ripped out for any reason.On the other end, we're going to have a six-way connector, and just so you know there is two different industry standards of how the cord is wired up, and our Roadmaster cord, the center pin, is for your power. They're also going to give us a six-way plug.

That way we can connect everything and wire it in. Again, it's got a little latch on there so it'll prevent that plug from getting pulled out. As far as the installation goes, it's pretty simple. We're just going to plug into the back of our motorhome, mount the six-way plug on the front of our Equinox, wire it up, and then we just connect the cord.Now, as far as wiring, the plug itself goes .. It's fairly easy and all the terminals are going to be labeled, but let's bring our Equinox from the shop and show you how we wired ours up.

To begin our installation, I want to start off by saying that our fascia is not on our Equinox because we just got done installing our base plate and wiring, and I suggest doing all of the components at once because it's going to make routing all your wires a lot easier, plus, with our fascia off, it's going to make a lot easier for you to see at home.Now that the wire's inside the loom, I can leave myself a little bit of excess, plus, we can always slide the loom forward or backward to make sure we have enough slack there. All routed back towards where I have my tow bar wiring, and I'll try to use some zip ties to zip-tie it directly to the base plate here and run it towards the driver's side. So now that we have our fascia back on, we can wire up the plug on the front of our Equinox. Now, your diodes are not going to come with a plug and socket, so we're using the Roadmaster 7-Wire to 6-Wire Flexo Wiring Kit, which is going to give you the car side plug along with an umbilical cord to connect everything up.So first, we want to separate our four-pole wiring and our charge line kit that we ran so we can get everything connected inside the plug. So we're just going to separate each one of these wires, we don't need to go too far back, just maybe one inch, two inches, to work with on each individual wire.

Split them back and we want to strip back the end of each one of our wires. This one did get a little damaged, but that's okay because we're going to have to strip back the end of it anyway and we can always cut off the little bit of excess and make sure that the installation is where it needs to be.Let's go ahead and trim that off. So, I'll pull the boot off the back of our plug, we want to feed the wires into the small end and slide the boot back out of the way until we have them all exposed again. Now, if we look at the back of our terminal, you're going to see all of the terminals are going to be labeled.If we start at the top here, it's going to have a TM, that's going to be for trailer marker, that's going to be our brown wire, and we go in a counter-clockwise position, the large pin is going to be labeled GD, that's for ground. And we keep going, LT for left turn, that will be your yellow wire, RT for right turns, it'll be our green wire, and then our center pin, you see there's an A with an arrow pointing to it, that's our auxiliary power source, so we want to make sure we hook our charge line up to the center pin.

You're going to grab yourself a really small Phillips screwdriver, we're going to loosen up the set screw, don't take it out because they're extremely easy to lose and really small, so you just want to loosen it up so that we can get the wire inside, and we'll grab the corresponding wire with the terminal.In this case, we're working with the trailer marker terminal, so grab a brown wire, make sure we get it all the way into the terminal and we'll tighten up that set screw and make sure it's nice and secure. And if you'll notice, I like to leave just a tiny bit of copper sticking out the top that way we don't have to worry about the screw hitting the insulation and causing any kind of intermittent issues, but at the same time, you don't want too much to where it's going to crossover and contact any of the other terminals. So we're just going to go through and hook up the rest of our wires.So, once you have them all connected, this is what it should look like. I always like to put some dielectric grease in between all the connectors, and this is just going to help keep out any moisture and prevent any kind of corrosion from building up. So I fill this entire cavity up so there's no pockets of air or anything else that could potentially get in there. Once we have a good amount in there, we can take the boot and we're going to slide it back over all of our wires. And then what I like to do is I'll take some electrical tape and I'm going to wrap the entire back of the plug and even tape some of the end of it, so again, nothing can get inside of the connector or the boot.Now we'll line up our plug, many of these provisions are in our base plate, so we'll just use the self-tapping screws and go right into them. Get one started, run up the other side and put that in as well. And the final step of our installation is going to be testing our wiring. Now, I suggest using a tester, that way, if there is any problems, we don't have to worry about figuring out if it's on the motorhome or on our Equinox.So I have my Equinox hooked up to my tester to simulate my motorhome, and if I turn on the tail light function, we can see that those are working properly, as well as the left turn signal, the brakes, and the right turn signal. All we have left to do now is hook up to the motorhome and hit the road. Now that we have everything hooked up, that'll finish up your installation and your look at the Roadmaster Charge Line Kit For Towed Vehicles on our 2019 Chevrolet Equinox.
