How to Install the Air Lift WirelessAIR Compressor System for Air Helper Springs on a 2019 GMC Sier


Hey everybody, Connor here today, etrailer.com. We're going to be taking a look at and showing you how to install the air lift wireless air compressor system here for our 2019 GMC Sierra 3,500. So in regards to air compressor kits, this is definitely going to be a personal favorite of mine. And the reason for this, it is extremely easy to install and use. It is a lot easier to install than pretty much any other air compressor system we offer. And the reason for this, everything is going to be contained on one bracket.

We have our manifold and our compressor mounted on one bracket, which we can bolt onto the vehicle with the U-bolt. Therefore, there's no drilling into the vehicle either so we don't have to make any permanent modifications. It's super simple to install. And definitely one, I encourage you guys to do at home by yourself.So in regards to using our airbags, we have two options; we can use the wireless remote which comes with our kit, we can also use an App on our phone, whichever we prefer. Now, I do really like this wireless remote here.

It's not too small, so we don't have to worry about losing it in the vehicle, has a nice ergonomic grip. So basically we'll show you how this works here. So we want to press the center button to turn it on. That's going to wake our controller up. So right now we have 35 PSI in each of our airbags.

That's actually going to be the max right now, the way it's currently configured, because it's set up to be used with the air springs that install inside the coral Springs.However, if you have a truck with the larger double bellow air bags, which have a much higher PSI rating of usually a hundred, even up to 150 in certain cases, we can go ahead and adjust the max inflation. In order to do this, we need to hold down the center button here for five seconds. This is going to bring up our menu and then we can go to settings, airbag tight, and then we can see here the different types of airbags, we're going to go with the load lifter or the ride control, both of those are a 100 PSI. So we'll go ahead and choose one of those, saved. Now, if we go back to the main screen here, we shouldn't be able to increase our pressure further than 35 PSI.Go up to 50, just as a baseline, hit the middle button and we should hear our compressor kick on.

So, as we mentioned earlier, we're going to see the current realtime inflation, that smaller number at the bottom whereas, whereas at the top here is going to be our desired set pressure. So let's go ahead and let that build now. And there we go. Now we're up to pressure. We heard our air compressor off. So the first step of our installation, we need to find a place to mount our main unit here, which houses our manifold and our compressor. So we need to find a place to mount this. Now the orientation doesn't matter for the exception of this logo can not face down. So we can't have it mounted like this, but it doesn't matter if it's mounted outside the vehicle.So we've looked over our truck here a little bit. We found that the best place to mount our little contained unit here, it's going to be on the passenger side here just directly below our rear passenger door. So you can see here, we have a nice open spot on the frame that we should be able to mount our unit right up in there. But before we do that, we're going to have a wiring harness on top of the frame here, there's going to be one little connector here, we'll take a trim panel tool, and we'll just pry that up, because it may or may not get in the way, we go to mount our unit here. So inner kit, we get a couple different options for hardware, depending on how we're going to mount it. There's some self tapping screws, there's some nuts and some bolts. And then we have a U-bolt, which is what you see here.And this is what we're going to be using for this particular application, because all we need to do is just simply come behind the frame rail here, come out to the top and then turn it to align it like so. Now we can go ahead and take our main unit here. We see we're going to have some holes on the top and bottom here, we're going to go ahead and line those up with our U-bolt. I'm going to use one hand to set it up in the place and the other one to hold U-bolt in the rear.Once that's on there, going to try to hold it as best I can with one hand, we're going to come back with a flat washer and then our lock nut. We'll go ahead and repeat the same combo of hardware here at the top. Take our 14 millimeter socket and secure it to the frame. Keep in mind, we do want to alternate back and forth when tightening. So we have about the same amount of threads protruding through our lock nut, both the top and bottom. So just going to go ahead, see if we can wiggle it, which we can't. So now we know it's secure against the frame. So the next thing we're going to do is we're going to grab the air filter, which goes to our air compressor. We're going to take the silver Barb fitting here, take it out of the package. And then we're going to thread this on to the back of our air filter.So there's going to be another one of these fittings on the top of our air compressor here. And basically what we need to do is, we need to take the airline that comes with our kit. Keep in mind that there's two different kinds of airlines, there's a harder one and then we have softer one here, which you can definitely tell just by squeezing it, it's going to be softer. And this is going to need to be used for our air filter installation. So as I said, we're going to have another Barb fitting on the top of our compressor. We're going to take one end of our hose, attach it to here. And then the other end is going to attach to the top of our compressor. But before we do that, we need to find a suitable mounting place for our filter that's going to be free of dirt and debris. We're not going to have to worry about too much water getting kicked up into it. So let's go ahead and do that now.So once we have our filter secure, we can go ahead and take our more pliable airline tubing. You can go ahead and stick one in onto our filter. Once we have it attached to our filter, we're going to take the other part of our line here. We're going to route it over to where our air compressor is, and then we're going to cut some of the slack off. Now we can go ahead and make our other connection here to the top of the compressor. Now we have a little bit more slack than we really need. So what we're going to do is we're just going to take a zip tie here and attach it to an existing wiring harness. So you don't have to worry about it falling down. That shouldn't be perfect.So the next thing we're going to do is we're going to take the coiled airline tubing that we get with our kit, and we're going to cut that in half because we're going to run one half from the manifold to the airbag on the driver's side and the other half from the manifold to the airbag on the passenger side. Now it does matter which slot goes into the manifold here, we have number one slot, that's going to go to the driver's side. We have number two slot, that's going to go to the passenger side. So we want to make sure that we have a nice and straight cut. But once we have that, we can go ahead and insert it into the push to connect fitting on our manifold. We'll simply push it in till you hear it click and then pull it out. Now we can go ahead and route this line here to the driver's side airbags, since we're in the number one port on our manifold.So now we've got our airline routes here from the manifold. We came up and behind this body mount here, we actually have a zip tie here. It's kind of hard to see, but we have it loosely because we're going to run another layer airline through it, but we're using this to secure it to our factory wiring harness. We have one here and then about six or seven inches up. And the reason this is important is, is because we have our factory exhaust right here. So you want to make sure the airline tubing stays above the frame and it doesn't lay over here on our exhaust because that will definitely melt the wire. Then once we come up here, we have another zip tie here. Again, just securing it to a factory wiring harness. And we actually came up and over the bed here.It's kind of hard to see, but if we look up in here above the gas tank, we're going to see part of the factory wiring harness here, we went ahead and attached another zip tie to our airline tubing. And we came out the back here, right where our airbag is. You can see up top here, we have another zip tie securing it to the brake hose here and the brake line. And now we just have it ran down here like so. So now we'll go ahead and cut our airline and attach it to our airbag. Pull it out to lock it in place. So if you'll notice in your kit here, we're going to have two of these T push to connect connectors. And basically what these four are, it's an optional install, if you want to add manual inflation valves to your system, therefore if the compressor die, you would still have a way to inflow your airbags.Now, essentially how these work are, what we do is we would just splice into one of our airlines here. It doesn't matter what point you can do it right here since it's nice and accessible, but we'd splice it in, cut the airline, attach one to the top one to the bottom, and then we'd have this other port here. And this would go to a piece of airline tubing. I went ahead and cut a small piece here just to show you. And this would allow us to mount our manual inflation valves, which are going to come with the actual airbags. So we can mount it there on there like so, and then we can go ahead and secure it to someplace on the vehicle that would be easily accessible. Now, if you wanted to, you could put the inflation valves and just zip tie it up here to where they are still accessible, but maybe not be the easiest place to reach, or you could run the airline tubing back to the rear bumper and have your inflation valves there. That all really just depends on preference, but we won't be installing these for this installation.So the next thing we're going to do is we're going to run power to our compressor, and in order to do that, you need to grab our wiring harness here that comes in the kit. We're going to grab the end with our square connector. It's going to be four pins here. It's going to match up perfectly with the connector here on our manifold. So we'll go ahead and plug that in now, we should hear an audible click when it's locked into place.Once that's done, we can go ahead and press this white tab up to lock it in place. Now we're going to go ahead and route our wires to the engine bay to our battery. But before we do that, we're going to have two connections that we need to make here. You can see a black and a red wire that come with our kit here, come with our harness that are attached to it. These are actually going to be connected to the black and red wires coming from our compressor. So what we need to do is we need to go ahead and cut off both of these connectors here and hardwire them to the wires on inaudible 00:11:47, using the included butt connectors. We'll show you what that looks like. We'll strip off about a quarter inch of the jacket, place one in into the butt connector, and then we'll crimp that on. We'll take the other end here and attach it to the red wire coming from our compressor.Crimp that on next. And then we'll go ahead and repeat the same process here for the black wire. Go ahead and give that a nice little tug. We do want to come back with a heat gun and go ahead and seal up these connectors next. So we went ahead and taped up our wires to some of our existing wiring here, just to make it look a little nicer, but now we can go ahead and route the bulk of our wiring harness up into the engine bay. We're going to do it to the frame rail here, and we're going to make sure we tie it to some existing wiring harnesses. So you don't have to make sure it's dropping down causing any issues, dragging the ground, anything like that. But there is a important note I need to make appear near the connector, is that we want to make sure that the wires leading from the connector aren't quite like this because if we get any water on these wires here, they're going to run down through there. They can get in there and corrode the contacts.So what the manufacturer recommends is we have a little bit of a loop down here to allow the water to run off, about just like that. Now we need to go ahead and attach our power wire to the positive battery terminal. Now, in order to get this cover off, we're going to have a bolt here which connects it to the firewall. That'll allow us to pivot this out of the way, and then we can sort of pry our cover up and that's going to reveal the positive post and the positive terminal on our battery here. So what we need to do now is before we just attach our wire directly to the positive terminal, we need to go ahead and install the inline fuse that comes with our kit. So we're going to go ahead and cut this wire here. I'm going to go ahead and strip some of the jacket off and then we can attach a butt connector.And once that's on there secure, we're going to take our fuse holder here and we're going to cut this in half, cut the loop in half here. And on one side, we're going to strip some jacket back, attach it to that butt connector. And the other side, we are going to attach a ring terminal. Let's go ahead and attach that ring terminal first.Now, before we go ahead and connect it to the positive battery terminal, we're going to go ahead and make sure our fuse isn't inserted because we don't want to insert it now for the step. And similar to what we did before is we're going to go ahead and take a 10 millimeter socket, to remove the nut on the top of our positive battery terminal. So we don't want to remove that nut completely. So again, we're going to go ahead and snip the ring terminal here so we can slide it around that bolt.So the final wire we have here is going to be the pink wire, which is for our ignition circuit. This needs to be attached to a keyed ignition source. However, we actually don't have to run it for our air compressor to work, but we are going to hook it up and show you guys how that's done. If you're not going to be using it, we can just go ahead and cut it off here and take the wire up. But in order to access this keyed ignition circuit, we need to get over to the driver's side because that's where our fuse boxes.So let's go ahead and route our wire over there now. So in order to get our ignition wire from the passenger side, over to the driver's side, where our fuse boxes, we had to go ahead and remove this little panel here. However, it's super simple to remove. There's just going to be several push pin fasteners here at various points, holding it down and you can see we have the pink wire ran. We have it zip tied to some existing wires. We've got to be careful here with the hood latch, you don't want to get that caught up in that. So we want to go ahead and secure it to the hood latch release cable, and then we just have it left off here and inside the fender well.So now that we have our ignition wire ran over here to the driver's side to our fuse box, we need to find a circuit rated for 10 amps or less that is keyed, meaning it only turns on with our ignition. Now he went ahead and did some testing here for you. And we found the perfect circuit takes a 10 amp fuse, and it's going to be located in the slot number 86. So to give you a better view of where the fuse was located here, it's going to be directly beside this 10 amp here.So we're going to go ahead, we already have the fuse removed, but we're going to go ahead and next, we can go ahead and attach our ignition wire to this circuit in order to do this, we're going to be using a fuse splice. We'll show you that now. So this is what our fuse splice is going to look like. If you don't have one, it doesn't come with the kit. So you're going to need to pick that up here through etrailer. And basically how this works is these two silver prongs here, they're going to install into the factory terminal, we're removed the fuse from, and then we're going to have two fuse slots on top. One of them is going to be for the factory 10 amp fuse that we removed from there. And the other one is going to be for the fuse for that circuit, which we're going to need to get one of those as well. We're going to be using a 10 amp. Then we can go ahead and plug in a fuse splice.Now the only thing left to do is attach our pink wire to the red wire coming from the fuse splice. So now that we have our two wires connected here, we can go ahead and plug in our fuse splice. We're going to secure our wire here up against the fender and we can re-install our fuse box cover. Now keep in mind, you may or may not need to extend the pink wire to reach over here to the driver's side fuse box. So you might want to go ahead and pick up some extra wire, or you may have some leftover from the harness that we cut off earlier. Now the final step, just to go ahead and install our fuse.So now that we have our fuse installed, we can go ahead and test our system out. We're going to take our remote along with our battery and insert it into here. Now we're going to go ahead and turn on the remote. So if we do have a leak, here's actually what it's going to look like. So you can see here, we have some bubbles forming and they're going to be coming from the push to connect fitting that we have our airline inserted into. So we're going to go ahead and deflate the system, we'll re-cut that line and test it again. And that'll do it today for our look and installation of the air lift wireless air compressor system here for our 2019 GMC Sierra 3,500.
