Hey guys, John here with RealTruck.com.
Today I want to show you how to install the Access LED Backup Light Bar on this 2015 GMC
Sierra Denali 2500.
So as you can see here guys, we've got it out of the bag.
Our light strip comes with everything you need to put it on the truck.
Of course, the light strip itself.
The wiring is already attached to it, so all you have to do is hook this stuff up and also
your instruction sheet to tell you how to put it on.
So, let's get this on the truck.
So, we're ready to install our backup lights.
The first thing we want to do because we're going to be hooking that into the factory
OE backup light wiring.
So we're going to take this taillight out and I'm going show you guys how to attach
that in here to the backup light and the taillight.
And you do that, just remove the two screws that are on the inside here.
And then once you do that you can just pull the light right out of the truck and what
that's going to do is that's going to give you access to the backup light, which is right
here and so, I'm going to show you guys here how to hook that in.
We're going to go ahead and install the light strip now.
And when we get done with that, we'll come up here and we'll hook it into this light.
We're going to take our alcohol prep pad.
Now these aren't supplied with that.
You can pick these up at drugstores, hardware stores, some have those.
If not, you can just use isopropyl and some type of a cotton cloth.
Not a cotton ball but a cotton cloth and wipe this whole area up here clean with this.
First wash it with soap and water and then we'll wipe it down with this.
So that way it will help the double-sided tape stick and keep that on the truck.
Okay, so we've got our area where we're going to install this all cleaned up.
Went ahead and peeled back about an inch and a half of the backing off of the double-sided
tape and what we're going to do is just leave that hang loose there.
And because we have the tailgate cap light style on the truck, we went ahead and ran
this in behind the wires that work the lights here so we can get this centered.
And then once we have it centered in place and where we're going to be wanting to put
this because this is a 39-inch strip.
So we want to center it on here so it looks right.
Then we'll go ahead and bring it up here to the back of the truck and we're just going
to push it down on the ends.
And get the ends in place and once we get that, where we can see where it's going to
go, then we'll go ahead and let the truck down and we'll get a hold of the pieces of
the backing that we put on there.
And we're going to peel them off from up at the top.
All right, so we've got it in place now.
So what we're going to do at this point then, is we're going to go ahead and attach it by
pulling the piece that we left loose on the backing.
And then just attach it.
Kind of go along and push down as you peel the backing and then that'll allow us to keep
this in place where we want it.
And then I'm going to grab the one on this side and pull it towards the center.
So now what we're going to do then, is we're just going to go along here once we have the
tape pulled and just push down on it to get it so that it's attached to the back of the
truck really well.
Okay, so what we're going to do then, is we're just going to unwrap this tape from around
the wire here.
And that's going to allow us to get in here to our backup light wiring and once we're
able to do that, then we'll be able to hook our new backup light right into that.
Now, you can't really use a wire-stripper on this because of the wires inside.
This is just a protective coating on them so we have to actually slice it and pull the
wires out of it.
So then once we have those out, then what we're going to do, is we're going to use a
couple of Scotchloks and you can pick those up at your local hardware store or your automotive
parts store and I'll grab those and I'll show you guys what those are and how to use those.
Okay, so we have here our Scotchloks.
If you look on this side, you can see that one hole goes all the way through.
One is blocked.
Well, the one that goes all the way through is the one we're going to put over our wire
on our factory wiring harness here.
And then what we're going to do then is the green wire is going to attach with the red
wire and I think, it's probably a good idea on this particular instance because this is
such a small wire, to go ahead and strip this and then just fold it over.
And then what that's going to do, is that just going to give it, even more, stuff to
contact to in here.
And so we're going to slide that inside here now and that's going to go into the side where
it's blocked on one end.
Now, make sure you get it back in there far enough that it sets into the metal piece you
see sticking up here because that's what we're going to clamp down.
Okay, so now I'm just using a pair of channel locks to clamp down on that and to push that
through.
And what that's going to do, that's going to lock that in and hopefully we've attached
those wires.
And then once you have that, then you just take this piece, fold it over and latch it
down.
Now, we're going to do the same thing with the ground wire.
We're going to just attach it right here on the ground side of this.
Okay and once you get to this point, it's usually a good idea to go ahead and test this
to make sure that it's working before we go and put this all back together.
So, I'm just going to set this up here for right now so it doesn't fall on me.
So, we've tested it.
Everything's hooked up right.
It's working correctly so we're going to go ahead and put our taillight back in.
There you have it.
That's how quick, simple and easy it is to install the Access Backup LED Tailgate Light
Bar on to your truck.
So, remember until next time, happy motoring.
