How to Install the Extang B-Light LED Lighting System on a 2018 Toyota Tundra


Ryan: Hey everybody, Ryan here at etrailer. Today on our 2018 Toyota Tundra, we're going to be taking a look at it and showing you how to install the Extang B-light LED lighting system for truck beds.I'll go ahead and flip our lights off. And this is when they're really going to shine. You can see in a dark room, they pretty much light up your whole entire truck bed and you shouldn't have any issues finding whatever it is you may need.This lighting kit is really handy. The extra light is always useful. So whether you work out of the bed of your truck lot, maybe you have a lot of tools back here and you're constantly in and out or maybe you like to tailgate, so you get together with your friends and you'd like to throw off the light and kind of show off what's inside of your truck.

This has got to get the job done.And since the lights are LEDs, they really are going to do a great job of throwing off a lot of light. Even in a well lit room, like we're in today, you can see that they're clearly illuminating our truck bed making it easier to see.These lights are really going to work out well for those of you that have a Tonneau cover like our customer does today. Now, even when it's sunny outside in the middle afternoon, when your Tonneau cover is closed it can still be pretty tricky to see inside your truck bed and get what you need. So the lights will really work out well then, too. So when you flip them on, you can actually see what you're doing in there.And when your Tonneau cover is down at nighttime the lights are going to be that much better.

So because of that Tonneau cover you can't hit your cab light and get that illumination back here that you normally could without the cover. So, that problem's going to be eliminated by turning these on. And it's going to prevent you from having to flip your Tonneau cover open for that cab light to work. Or maybe say, you need two hands back here and you can't hold the flashlight to see what you're doing to get your stuff out. So, the lights here on this switch are going to eliminate all of those issues for you.I will say one thing I really would have liked to have seen is everything you're going to need to get it installed included in this one kit.

It is lacking a few of the parts and pieces that you're going to need to completely set it up the way you want. But it's really not a big deal. Etrailer offers everything you're going to need, and I'll show you what I use to get the job done. Now, as far as the installation goes, it's really not too bad. It's a little tedious and time consuming just because we do have to run some wires.

But as long as you take your time you should have no problem getting it done at home in the garage or maybe even in the driveway. Speaking of which, let's go ahead and do that together now.To begin our install, we're going to be in the bed of our Tundra. And first thing we're going to need to do is find a spot to mount up all of our lights. But before we get too carried away with that, in the past when I've done these I have noticed that the very ends of the wires have these little indicators stickers that lets us know which one is positive and negative.I've noticed that these things can come off really easy and then it leaves you a little confused trying to identify what wires what. So I do suggest before you start working with them, just take a piece of tape or something like that and put it on the end of the wire to help you identify it, if these do happen to come off.So where I'm going to mount our lights is along this edge here underneath the bar Tonneau cover rail where the lights aren't going to be in the way of anything or really interfere or be all that noticeable whenever they're not turned on. It's a nice flat edge. When you mount these, you want to be sure that the surface is really nice and clean and dry. I like to take some rubbing alcohol and wipe everything down real well. The end of the wire that has the light on it, you're going to want to make sure this is the light that's going to be towards the very front of the truck. So this one you want to start in the front of your bed and work your way back.We got a couple of different options on how we can actually secure our lights. You can either use an included screw and use this little bracket here on the light to hold it in place. But what I've found is actually the included sticky tape is very, very strong and works out really well. So I opted to use that instead of the little screw. Once the area is clean peel off that backing paper, line it up wherever you want it and push it firmly against the surface. And this is how I'm going to mount all of our lights.So just to kind of give you an idea on how I actually mounted up all of the lights, here's what they look like. Now, when I'm doing this what I try to do is space them apart evenly. That way, when we turn our lights on everything will be evenly distributed and then they'll really illuminate the back of our truck.Now what we need to do once our lights are mounted is figure out a way to get the end of the wires dropped down underneath of our truck. So there is a factory hole right here you could always just drop them down through. However, we would have some wire exposed and I feel like you might get hung up on that over time or something like that. So, what I've opted to do is just drill a new hole. I'm going to go right up here in this area and I'll drill an opening and then use a grommet. Once that holes in you can push that grommet in and feed the wires through and it'll look really tidy and clean.Whenever you're drilling this, be careful. Because if you have a really long drill bit and kind of lose control of it, you don't want to punch out the other side of your truck bed. So, keep that in mind. The step bit should get it going and if you have to come back with a regular drill bit to enlarge it to the proper size, we can do that then. inaudible 00:06:25. Once we enlarge the hole to the correct size, we'll just push our grommet in and we can take the end of our wires and start to feed them through to the bottom side of the truck.Once we had our wire through what I did is just came back with some RTV silicone. Just put a drop on it, just to help keep everything sealed up.From there, I just simply repeated that same process over here on the passenger side, mounted up our lights the same way. And again, dropped our wire down to the bottom side of the truck by drilling a hole and using that same grommet.So now underneath the truck here on the passenger side, what we need to do is route those wires that we dropped down over to the driver's side so we can hook everything up in one area. So here's where our wire came down and I simply zip tied it to some factory wiring here, and simply just routed it towards the driver's side of our trunk. It's right up through here. It's a little tricky to see, but you can feel it really well just right above our spare tire. Comes out right here over our frame rail. And, this is where we let it drop down.So now what we can do is work on connecting the ground wire from the lights over here on the passenger side and the lights over here on the driver's side. So what I did was kind of separated the wires, that way I can kind of work with them individually. And these are the two ground wires from our LEDs. So I kind of just moved these other ones out of the way that we're not to be working with for now. What we're going to do though is trim off the excess wiring here and use a ring terminal to get them connected to each other. So, I'll give us a little slack, trim that off, going to strip back the ends to expose the insulation underneath. inaudible 00:09:18Now, we're just going to twist these together. That way it'll share the same ground. We want to get them nice and tight. Now I'm going to take a ring terminal and crimp it on. So this ring terminal is not included. If you need them you can find it here at etrailer. So that just slides on the bare end of the wire. Take our crimps and smash it down.We need to find a spot to ground our ring terminal to the chassis. Well, if you look up right here there's going to be a bracket connected to the body of our vehicle. And I think that should work out really well. I'm going to take that bolt out using a 10 millimeter. inaudible 00:10:15 We'll take our bolt, just put our ring terminal over it, like so. And then we're just going to re-secure it. inaudible 00:10:31.So, while we're underneath the truck, now it'd be a great time to run a power wire from back here all the way up to the truck's battery. Now, the power wire is not included with this kit so you will have to pick this up separately and you can find that right here at etrailer.So I already routed it, but what I've done is just kind of came over our frame gear next to our spare tire and secure it with some zip ties and do your best to avoid hot moving parts. I essentially just followed the frame right up along through here, zip tying in it as we go. And it's a little tricky to see, but I just stayed inside of our frame rail here along the whole length of our fuel tank. So the wires kind of up in this opening here, kind of to the side of our fuel tank. inaudible 00:11:35 You can kind of see it there, I just continued along, and it comes out right here. So from here, I just follow these factory lines. I put that wire on the backside of it, that way this heat shield will kind of help protect it.At this point, I was able to route our wiring up along our firewall. And how I did that is I used to pull wire. So I went under the hood, dropped down a piece of air tubing, you can also use a coat hanger, something like that. Tape your wire to it and then you're able to pull it right up where you need it to go.So now under the hood, here's where our power wire came up, right up along through here. And what we're going to do now is connect it to a fuse holder. What we're going to do is strip the insulation back, and twist, and I'm going to crimp on a heat shrink butt connector. So just slide right over that end and get crimped down. We can take our fuse holder, make sure that the fuse is not installed. That's the very last thing we're going to do once everything else is hooked up. inaudible 00:13:28 We'll cut that in half and strip back those ends, as well. On one end of our fuse holder we're going to take a ring terminal, crimp it down. The other end of our fuse holder, it's going to get placed in the other end of our butt connector here. And we'll crimp that down too. Now since I have a heat shrink butt connector, I'll come in with my heat gun and seal up the ends. inaudible 00:14:14.So then what we can do is hook up our ring terminal here to the positive battery terminal. So open up that cover, and right here we're going to have a 12 millimeter nut. You're going to remove that, slide our ring terminal over and be sure, again, not to have your fuse installed yet. Let's slide that over it and then simply tighten our nut back down.We're now here at the back of the truck. Our main power wire that we just ran up to the battery as well as the two positive or power wires from our lights, these are going to get hooked up to a switch. So before we hook these up, we need to figure out a spot to mount the switch, that way we can run our wires up to it and get them plugged in.This is the area that I chose to mount up our switch. So I've just created an opening large enough to work with, but not so big that our trim piece here wouldn't it covered up. And this right here, I made it just wide enough that our switch will fit in there nice and snug and we won't have to worry about it bouncing around. I will say right behind this first layer of metal, there is another sheet of metal and I drilled through it too. That way we can easily connect our wires up to the switch. So, once you make this first opening, what you're going to want to do to create that next opening is remove your tail light. That's just going to make life a lot easier. The tail light is held in place by two Torx bit screws.We'll simply just pull those out. You can grab your taillight and work it out and release it. Those tabs are what we're pulling to it to break free. Then we can kind of just let it hang for now. And so right here, you can see that opening that I drilled and created to allow our wires to pass through everything.Now, what I did is just ran our wires up into the tail light pocket, really simple. When they're hanging under the truck you just push them straight up and you can grab them up here. We're going to get these ready to hook up to our switch. The first one we're going to do is the power wire. I'm using a spade terminal. Again, these are not included so you will have to pick them up separately. But strip the installation back, I'm choosing to use the yellow size for our thicker wire here. And crimp it down. inaudible 00:17:42 And for our two light power wires, strip them back and we're going to twist these two together. Get these nice and tight. I'm going to use a blue size for this one, slide that spade connector over there, crimp it down. Then what I'm going to do is just take these ends and run them through the hole that we drilled.So here where our wires pass through we can now grab our switch and get them plugged in. These terminals will just simply slide onto the prongs here on our switch.Now that we have our switched plugged in we can simply just push it into position.And now that we're finished up back here, we can go ahead and re-install our taillight the opposite way that we removed it.Now that we have everything hooked up, we'll come back under the hood and put our fuse in. That way we can test our lights and make sure they're working properly.So the big moment of truth, let's go ahead and flip our switch and make sure our lights turn on like they should. So they're turning on correctly. Let's go ahead and flip it the other way and make sure that they turn off. So it looks like everything is functioning properly.And that'll finish up our look at and our installation of the Extang LED lighting system for truck beds on our 2018 Toyota Tundra.
