How to Install a Roadmaster Tail Light Wiring Kit on a 2016 Chevrolet Spark


Ryan: Hey everybody my name is Ryan and here at etrailer we install, test fit and review a lot of different parts. That way we can try to answer any questions those of you might have and that's exactly what we're doing here today on our 2016 Chevrolet Spark. We're going to be taking a look at and showing you how to install the Roadmaster Vehicle Wiring Kit for Towed Vehicles. So you're going to need a total of five main components to flat tow your Spark down the road behind your motor home. The first one is going to be your base plate and that base plate is going to be that solid and reliable connection point, that way you can hook up your tow bar to it. That tow bar is going to be that second component.

That's going to be the physical link that connects the front of your Spark to the back of your motor home. The third main component is going to be safety cables and these are there in the event of an unlikely disconnect. These are going to keep your Spark connected to your motor home.The fourth main component is going to be tow bar wiring and the wiring is going to transfer the lighting functions from the back of your motor home to the back of your Chevy, keeping you safe and legal. Last but not least, the fifth main component is going to be a braking system and that braking system is going to apply the brakes in your Spark whenever you hit the brakes in your motor home. That's going to help bring you to a more safe and predictable stop and this is a perfect example on how the wiring is going to work.

As you can see we have the left turn signal going on our motor home and it's transferring back here to the left turn signal on our Spark. But not only are we going to get the left turn, but we'll also get our right turn, our brake lights and our running lights. So we have all of our bases covered to stay safe and legal. Now, what's pretty nice about the bulb and socket is that it's going to be completely isolated from your Chevy's factory wiring.We're not going to need to tap into that at all. So, if an electrical issue or a short we're to occur on the motor home side you're not going to have to worry at all about potentially damaging any of your factory electronics, which to me that put my mind at ease.

These electronics nowadays are really advanced and you don't want to do anything to jeopardize those and with this kit, it's something you're not going to have to worry about. I really like the fact that this kit uses LED bulbs. So they're up to date with the times, they're super bright and you know they're going to last a really long time. We're not going to have to worry about changing them out nearly as much as you would with those standard and candescent type bulbs and they have a nice modern appearance to them as well whenever they're on. So, they kind of look cool.

Now, one downside to the bulb and socket is you are going to have to drill a small hole into your taillight housing. So, that is one of the concerns you might have.I do suggest sealing that up really well when you do, do that, that way you don't have to worry about leaks or anything. But with that being said, even the diode wiring kits, the kits that you use diodes. Those still tap into the factory wiring, so one way or another you're still going to have to do a little bit of work. The bulb and socket you got to drill that hole and that diode wiring you're going to have to tap into the factory wiring harness. So you kind of have a choice there and I will say the bulb and socket isn't a bad one. Now, there is one thing I do want to mention and that is that this kit is not going to come with a connector that you can wire into the front of your vehicle. That way you can plug your wiring into it from the back of your motor home. Not really a huge deal, actually it's a little convenient at times because you can kind of pick and choose what connector you want to work best with your setup. Today our customer has a four way flat connector.So this is just a pigtail that we use a splice right into the wiring, super straightforward. If your set up is like this and you can pick up that pigtail right here at etrailer. But a more commonly used one is a six pin round-style connector and that is really common in the flat tow world and that's the style connector I would personally recommend. But other than that regardless of what connector you hook up, it's going to be super easy. You're just going to take the appropriate cable, plug it right in and hook it to your motor home. Now if you do plan on using that six pin connector, there's a kit available with this wiring that comes with a wire that has a six pin on one end. So you can plug into that six pin connector and a seven way on the other end that way you can plug into the back of your motor home. So if that's the route you want to go, I would suggest picking up the kit and again, you can find that here at etrailer.So at the end of the day, not a bad choice for tow bar wiring, it's definitely going to get the job done. Now, as far as the installation goes, it is quite a bit of work and it mostly lies just having to route all the wiring. But as far as hooking it up and everything, it's pretty straightforward. So as long as you take your time you should have no issues getting it done at home. Speaking of which, let's go ahead and do that together now. So to begin our installation, we're going to be here at the front of our Spark and we have the fascia removed. You don't have to have it removed to do this, however I'm doing this at the same time that we did our base plate so we have a lot more room to work. With that being said, what I did is I took one end of the bundle of wire that comes with the kit and I started to connect it to a four way plug here and this four way plug does not come included with the kit.With that being said, I hooked up three of them I just went color for color. Green to green, yellow to yellow, brown to brown and I used some heat shrink butt connectors which you can also find here at etrailer to pair them two together. So I left one open so I could show you how to do it. What you're going to do is just strip back the insulation, on both end, your connector end and your wiring side. I crimped on the butt connector here, but then you'll just take the stripped end of the wire, pop it into that end of the butt connector and crimp it down. Since these are heat shrinks, what I'll do is I'll take my heat gun and seal up the ends. Once we have that all connected, we can run the bundle of wire from the front here towards the back of our vehicle. So I'll go ahead and do that now and show you the path that I took to get back there. So I got our wiring ran and comes out of our plug here and I did tape up our connections here just for a little protection.I just figured I'd mentioned that. But what I did is I just shot it across the top of our base plate, used the zip tie along the way to secure it. Comes out right through this opening, kind of comes around and goes through there to the bottom side of our vehicle. So now underneath the vehicle, here's where our wiring came through and I just secured it through here and on the bottom side of the frame rail. Now, when you're routing this wiring you want to do your best to avoid any hot or moving parts. I brought it down. Kind of comes down, there's actually a plastic panel here if you kind of pulled out on that you can kind of sneak the wiring and under there. Comes out right here, pushed it through this hole in the frame, continued back with it, shot it straight through here. Again, make sure you zip tie it along the way.Then I started to push it up into the side and it comes over our axle and then right in front of the coil spring, there's a hole in the frame. Pushed it through that hole towards the back of our vehicle where our wiring comes out through there. So, here's the rest of our bundle. What we're going to do now is kind of let this hang here and move up top and get our tail lights removed. So to get our tail lights removed, we're going to open up our rear hatch and they're going to be held in place by two Phillips head's screws. Let me get those removed. What we should be able to do is kind of grab the tail light, kind of wiggle it back and forth gently and kind of pull back on it as well at the same time. Now once we get it freed we can remove our bulbs, that way we can work with just the light. So, these are just quarter-turn. So you're going to grab the back, rotate it a quarter turn and release them.So I'll just set this light to the side for now and repeat the same process over on the passenger side. Now we can do, we can grab our tail light and if we look on this top portion here it's nice and flat. So just to kind of give you a reference point if this we're on the back of the car, we're looking at this pocket here. So this flat surface we need to drill a hole, that way we can get our bulb inside of the housing. So, I kind of lined everything up and eyeballed it and I made a black dot where I want to drill my hole and you want to use a one inch hole saw and what I like to do is kind of get it started with the pilot bit. Then kind of hold it upside down like this, that way when we're drilling with our hole saw all the shavings are going to fall down and not get trapped inside of our taillight housing and since this is plastic you want to be real careful. You want to take your time.I typically find using low pressure and higher speed does a better job as opposed to really putting a lot of pressure on it. Get everything lined out here and drill the hole. So now that we have our hole drilled out. We can grab our bulb and you notice these little pieces of metal here, these are actually going to retain the bulb into the housing. But if you try to put that in there, they're not spread out far enough apart. So it's just going to be able to come right out with very little effort. So what you're going to want to do is take a peck 00:11:55 or a small screwdriver, something like that, and we just want to kind of pry these out a little bit. That'll create a little bit of tension when we go to push the bulb into the tail light and these will do a good job at keeping it in place. So, I would just like to bump them out a little bit and try it out.Sometimes it goes right in exactly how you want it, other times you may have to close them up a little bit or spread them out a little bit more. So that looks pretty good, something like that. I'll push it in there and it's still a little on the loose side, so I'll come back, open them up a little bit more and then that should do the trick. So that's exactly how we want it, we want it to kind of snap in there and not be able to pull out easily at all. So what I went ahead and did is took some silicone and sealed everything up really good that way we don't have to worry about any moisture or water getting inside of there. So I really blobbed it up there, that way it'll be extremely sealed. You can pick some of the silicone up right here at etrailer. Now while this is drying, what we're going to do is repeat this same exact process for our other tail light. So, now we can start to get our wiring set up.So, here's where we let it hang underneath the vehicle for the time being and all I did was just push the wiring up through our tail light pocket, so pretty straight forward there. You can kind of pull up the slack and what I've done is just separated each wire. Originally they're all connected like that, they're bonded and you can just put a slice in between them and kind of peel them apart. With that being said, over here on the driver's side we're not going to have to worry about the green wire over here. So I'll just push it back down through, out of the way for now. Then, I'm going to shorten up our other three wires. So I guess a little bit of length to work with here. Maybe something like that and I'll trim them, then I'm going to strip back the ends on all three. What we can do, is the white wire that we trimmed off, as well as the brown wire, we can take that extra length, feed it down through, because these two are going to get ran over to the passenger side.So we're going to tie these in to these wires and run the rest over to the passenger side. So I kind of just push this down, make it a little easier and more manageable to work with. So I'll take the end of our white wire and strip back that installation and I'm just going to tie that right into our other white wire here. So I'll just take them and twist them together. I'll do the same exact thing with the brown wire. So what I went ahead and did now, is just use some more heat shrink butt connectors to connect the wiring we ran up here to our tail light to our bulb and socket wiring. So here on the driver's side you're going to take your brown wires, connect it to the brown wire for your ball and socket. The white wires will go to the black wire on your ball and socket and the yellow wire will go to the red wire on your ball and socket. The kit does come with butt connectors to make these connections, they're not heat shrink and they'll work just fine.However I do highly recommend switching over to these, they're just a lot more durable and will really do a great job at preventing any potential corrosion. So what I went ahead and did, is just use some electrical tape to really help keep everything nice and sealed and at this point we can reinstall our tail light bulbs. Just going to push them back in place and then rotate them back quarter turn and then re-secure those. Sometimes they can be a little tricky to get lined up, but get all three of those back in and then we can just re-install our tail light the opposite way that we removed it. So now we can come back underneath of our vehicle and route those wires from the driver's side over to the passenger side. So they come down right here and what I did was just route them kind of behind our fascia. So they come up through our bumper beam, kind of just continue back through there, through there and they go up into the tail light pocket.Now before I pushed them up into the tail light pocket I added a ground wire, so you have a lot of extra length on those three wires that we just pushed up. So what I did is, I cut maybe two foot off of the white wire and created ground and that's this right here. So all I did was attach a ring terminal, crimped it on and then I used a screw to secure it to the body of our vehicle. Now you want to ground it to a nice thick piece of metal like we have here that way it will ensure a good ground. With that being said, I also pushed our ground wire up into the taillight pocket as well. So I went ahead and hooked up our tail light over here on the passenger side, pretty much the same way we did on the driver's side. So, here's where all of our wires come up. The green wire going to get butt connected to the red wire here.The brown wire, it's going to get butt connected to the brown wire and our white wire as well as that white ground wire, that's going to get connected to the black wire here. So now that we have everything connected up, we can go ahead plug our light bulbs back into the tail light housing and re-install the tail light the opposite way that we removed it. So now it's a good idea to test our wiring out to make sure everything is working properly. So I just hooked up to a tester box and then we can turn on our tail lights. Our left turn signal, our right turn signal and our brake lights. That'll finish up our look at and our installation of the Roadmaster Vehicle Wiring Kit for Towed Vehicles on our 2016 Chevy Spark.
