Air Lift Wireless ONE and Air Lift LoadLifter 5000 install

I installed the Air Lifter Wireless ONE compressor and LoadLifter 5000 airbags on my 2006 GMC 2500 about eight months ago, and I would like to share the install process.

The directions are very clear and easy to follow. Everything was bolt on, so no welding or cutting of any kind.

The air bags attach to the frame where the factory bump stop is located. Remove the bump stop and attach air bag. The kit comes with a plate that attaches to the axle. Depending on truck this step may be different.

Next is the compressor. There is a plate located under the bed of the truck that I used for the compressor location. The air manifold can only be oriented in a couple of different ways per instructions. I attached the manifold to the bed cross member.

The plumbing and running of the air hoses was most time consuming. I had to drop spare tire to run an air hose to the rear bumper for the manual inflate. Before I ran any air hose I installed in wire loom for protection. This is not critical, but I did it and also helps clean up the install.


Electric wiring is next and final step.

I did not like the way Air Lift wanted to power the compressor directly from the ignition fuse tap so I installed a relay........... https://www.amazon.com/gp/product/B0...?ie=UTF8&psc=1
The relay is powered by a 12 volt accessory stud at the fuse box and the relay is tripped by the ignition fuse tap. The compressor will only run with the ignition on.

Once again I wire loomed all the electrical wiring for protection and for a clean install. If you plan on buying bulk wire loom, I suggest Amazon. It is 1/3 of the price compared to the auto part stores!!

I really like having the compressor. It will keep the bags at the desired 5 psi while unloaded and air the system up with a push of the button. You can control the pressure in the bags on the fly while driving down the road.

I have around 4500-5000 towing miles on this system with no problems. I highly recommend Air Lift. Their customer service is top notch. When I first installed the system the air manifold was registering the wrong psi. I called customer service and they promptly sent a replacement.

Hopefully this may help someone who may have questions about the install process. There are also videos on YouTube on this type of install.

I also used a relay to install my airless one compressor. Like you, I believe it is a safer install. (Might have been you, but someone on here noted the relay install.)

As for the compressor, I installed it in the bed at the front left. And with a fiberglass tonneau cover, it will remain nice a dry at all times. I very seldom load anything in my truck other than some lumber, so nothing will get near the compressor, and under the 1500 GMC, I could only find two places to install the compressor. Both were on the outside of the side frame rails, making it next to impossible to use the power drill to drill the screws into the frame.

There was one place on the inside of the right rail, but too close to the exhaust for me.

As for bags, I used Firestone Ride Rite, but that is primarily due to the fact I had a very bad experience with Airlift bags a few years ago.

I have the same bags and compressor on my f250. I made a mounting bracket from sheet metal steel from HD and secured it up to the underside of the bed with the manifold and all secured to that.

I wired to the 12v accessory power for the 7 pin tow plug. Nice because the wires r so short and that it is switched for accessory ignition. Maybe useful for someone else trying this in the future too

I have a Wireless One kit to install in my Forester I'm just wondering about the relay. The wiring harness that came with mine has a relay on it, is it for something else? Did you install an additional one?
Thanks I'm not a great electrician.

Different. He is talking about how he receives power from the 12V battery constant, but rather than having it always powered, he used a relay which is wired to ignition power. When power is tripped from ignition it switches the relay, which then supplies power to the compressor via the 12V constant.

Depending on where you want to wire it up, this is a fine approach. like I said, I wired mine to the 12V ignition switched wire on the 7pin trailer harness. It is 20A. For my ground, I simply drilled a hole in a safe/appropriate spot under the truck in the framing piece holding the spare tire up, and used a ring-terminal. It works perfectly and no having to fish wires all the way up to inside the cab, under the hood (battery terminal) all that jazz. Zero issues and I got this idea from powerstroke.org where other people had done it.

BATT+ (in MY truck, check yours)
Receives power only when your ignition is turned on
OR if your trailer is hooked up, it will receive power from the trailer battery.

Can't wire to the trailer hot on most GM vehicles. I know on my previous two, and my current pickup the B+ wire to the trailer is hot at all times. (All 1500 series, cannot speak for larger trucks.)

As for the "new" relay wiring, this is basically the diagram for how I wired mine under the hood...

The air manifold is the brain in the system. When the manifold needs air for the system it trips the relay on the Air Lift wiring harness to turn on the compressor.

Air Lift (per directions) wants to tap power from an ignition source so power will only go to the system when the ignition is turned on. If you tap into a constant 12 volt and a bag or hose develops a leak when the truck is parked, it will run the compressor and may drain your battery(s). I do not like the way Air Lift wants to tap directly into the fuse block to power the system and the fuse block stills has to power the ignition fuse. To me, the fuse block was only designed to power only the ignition and not the ignition PLUS a compressor.

On my truck the 12 volt at the 7way plug is constant hot, so tapping there was not an option for me.

To keep the extra draw off the fuse block, I added a relay to power the system. The relay has constant 12 volt power supply from an extra 12 volt stud for accessories. The switch power to the relay comes from the wire tap into the ignition fuse. I believe the switch voltage is 0.25-0.5 volt (can't remember). So I'm adding minimum voltage to the factory fuse block.

Mine is wired the same as f5moab.......GREAT DIAGRAM!

Fantastic thanks guys that really helps clear it up for me. I have a Ford E-450 chassis, I'll get the tester out and poke around.

I am thinking of installing bags on my truck. Would there be anything wrong with wiring the compressor to the running lights? That way you could have the engine off, turn on the running lights and listen to see if compressor is running.

There was a good post a guy had on powerstroke.org for installing his wireless One. He actually installed on his f150 (has a 350 now) but it was so similar I used it as a basis for how I installed mine. You can search there I bet and find it.

That's how mine is except I just wired to a 12v ignition powered source. Put the key in, turn it to ON/ACC but don't start the truck and if my bags need air, the compressor turns on before I even turn the truck over (start it). Likewise I'd say they need less air it let's it out.

Mine turns on, if needed, when I turn ignition to On.

Always been curious as to what would happen if you connected an item with a 12A draw such as the Airlift compressor to a 15A circuit and the factory installed items on that circuit were power to around 12A when the compressor clicked On and started to draw an additional 12A. I would guess it would blow the 15A fuse in the fuse block; if you were not on the buss side of the fuse. But what would happen if you were on the buss side (circuits that feed the 15A fuse)? Don't want to try it.

I noticed Captain America did not use the fuse tap that came with the Airlift system. (Great photos I might add!) I didn't like it either and on the newer vehicles that use the Micro ATR fuse, it fits too loose on the fuse leg. So I also installed a fuse tap similar to the one in his picture. Harder to find for the new ATR Micro fuse but Autozone does carry the Cooper Bussman Double ATR fuse tap.

And on these newer GM products, most of my 15A circuits were using the newer Micro 3 fuse that has three circuits on one fuse.

And I will add, as Captain America shows in his great photos, use plastic conduit to protect the electrical wires and the air tubing.

I used it on the electrical wiring from front to back, but only used it on the air tubing where it went down and over metal parts (when I fished it from the bed down under the truck).

You can wire the system to the running lights; however, the system will only run with the running lights on. You have to manually turn the lights on to power the system. The bags need a minimum of 5 psi, with temperature change or loading of the truck the compressor automatically kicks on to adjust air pressure.

I can turn the key to accessory or run and the system is hot without starting the engine.

This is the fuse tap I used...https://www.amazon.com/Pico-0956PT-B...=mini+fuse+tap

I bought mine from a parts store. I should of bought it from Amazon, its half the price.

I installed the firestone 5000 air bags and the AirLift Wireless one compressor on my 2015 RAM 3500. They make a big difference. the instructions say to maintain a minimum of 5 psi to prevent damage to the air bags
