❤❤❤ hi mounted my 4 Viair air compressors in the toolbox in the bed of my pick up truck for my airhorns. I did not want them underneath of the vehicle because they’re going to be exposed to a lot of bad weather, water, and dirt. I’ve pumped my system all the way up to 250 psi it all of my fittings did not blow apart but I sent them with pressure switches that go up to 170 psi and then all for compressors get turned off. I put the system together just for air horns to keep people awake when they’re driving down the road and they might for some reason not be paying attention. I don’t want him to crash into my new truck so I can give them a check up from the neck up as they start weaving into my lane. I’ve got a 2 1/2 gallon air tank and the system is unbelievable when I show it to anybody they are totally blown away. ❤❤❤
Sounds like a nice setup. The air compressors are sealed up pretty good except for the filter part that takes in air. Mine are high enough up under the truck that they stay pretty clean all the time. As long as I'm not out mud bogging or anything they should be fine. I've wanted to get some air horns for my truck too but have not as of yet. I mainly use mine for airing up tires and blowing things out to clean the dust out. Maybe one day I'll throw on the horns. I think it would be pretty nice. I've seen setups where the normal horn works until you flip an upfitter switch then the air horn will work instead of the normal one. Would be pretty nice. Thanks for the comment!
❤. I bought two starter solenoid’s for my air compressor system using the. 4 VIAIR air compressors for my system. I have four gauge wire copper wire, not aluminum coated copper wire that goes from my battery inside of the pick up truck toolbox that’s in my bed. People need to talk about the copper wire. That’s coated with aluminum. It’s not good for the system. If you’re pulling high amperage like I am. People need to be careful as to what they purchase off of Amazon. Some of it is real cheap junk. Cherry pick the wire that you purchase. I have an 80 amp fuse, about 8 inches away from the positive terminal on my battery. The 4 gauge wire goes all the way down the frame of my truck open to the Tool Box that’s in the bed of my pick up truck to activate. 4 VIAIR air compressors. I do have six of these compressors, but there’s not enough room in the toolbox for. 6 air compressor, so I was only able to put 4 of them in the toolbox with a 2 1/2 gallon air tank. The system that I put together is very detailed. It’s very reliable and I did hit the bypass/boost switch to bypass the pressure switch and ran it all the way up to 250 psi and none of the hoses steel braided hoses I might add did not come apart, but I do have a pressure switch that shut everything off at 170 psi I put the system together just for super loud Hadley air horns in the grill of my truck where you cannot see it, but it will wake the dead if I need to wake somebody up before they hit my truck. It’s a shame that we cannot post pictures when we post comments or videos on UA-cam because my system is completely highly detailed ❤❤
Nice.. And yes, I've dealt with the wire issues before. It does take some digging to get a good piece of wire off amazon. You never know what that stuff is going to be when you finally receive it. My first setup I did have the wire from the battery to the first fuse there disintegrate basically. I replaced it with a better wire as well as some heat shrinking and it's been good ever since thankfully.
I like your system it’s very detailed. It’s a clean application, but I would never put my air compressors in an area that could get filthy, dirty and get water splashed all over them everything that I put together, including. 4 VIAIR air compressors are in the toolbox in my pick up truck, so they never get in the weather. I don’t want them to be splashed with water or any kind of mud and filth. I have a 80 amp fuse that activates all 4 VIAIR air compressors at the same time but I do have a switch where I can activate just two of them if I do not use that switch all 4 four of them come to life with the flick of one switch if I want rapid air recovery for my airhorns. I think everybody should stay away from the copper coated aluminum wire. Copper coated. Aluminum wire is not safe for high amperage. Be careful when you buy off of Amazon. Make sure it’s solid copper that is not coated with aluminum.
Yeah, I went through thinking about it under the truck like that. Being I don't have a tool box in the back of my truck I just decided to put them under the truck. The air compressors are 100% sealed except the air intake part, which is not really a problem as I wouldn't have them on while I'm off road or driving anyways. So far, after almost three years of them being under there, they are surprisingly clean. I think they are high enough under there and the transfer case gives them good blocking from most of the grime. Only real issue I've had is with the pressure switch in the manifold being straight up and down allows moisture to get down into the switch and rust it out. I've had to replace it twice already.. Thanks for the comments!
I like your set up! I'd like to install my tank above the spare as well. I'm trying to get a good look at what you used for a bracket. Does your tire hang a little lower than before the install? It appears that your bracket is below the crossbars that run between the frame rails. Thanks!
Yes it does hang about and inch or so lower with my setup. It’s hard to get a good view of it while the truck is on the ground. It was a one or two inch square tube that was used to mount the tank. Works great so far. Up and out of the way and I still have my spare tire. Thanks for the comment!
Heyhey, That is mounted with the Viair 95900 Compressor Mounting Bracket that I got from Amazon. Works like a champ. My only issue, which I didn't think about at the time, is that the compressors are taking the space up if I was wanting to get a 60 gallon S&B diesel tank. But other than that it works great. Thanks!!
Question buddy, I'm installing this system as well and I was to have the compressors turn on with a aux switch as well. My question is looks like you wired the compressors straight to the battery but to still have it turn on/off with your aux switch? How did you do that?
The compressors are wired to the solenoid. The solenoid is wired directly to the battery. The pressure switch is wired to the solenoid and to the upfitter switch. The upfitter powers the pressure switch and if it sees less than 160 PSI it sends power to the solenoid which will feed power to the compressors.
It's been fine where it's at. Seems that it's high enough that nothing really gets on it. I don't do any mud bogging or anything like that so it seems to do fine. The pressure switch has died on me once though from moisture and I just replaced it. Was like 15 bucks or so I think for that.
❤ I noticed that your steel braided wire is too close to the exhaust that can create a leak when the steel braided coating gets real hot. It will cause a leak. Trust me, I have experience that it was my fault that I did not properly route the steel braided hose that goes from my toolbox to my air horns in my air pressure gauge in the cab of my truck. Keep your steel braided hose away from the exhaust. The hose will last much longer. ❤❤
Thanks for the tip.. I've had it under there like it for over two years now and everything has been fine so far. Hopefully it will stay like that! I will keep an eye on it though.
You would love to see pictures of my operation in my truck. I’m very proud of what I built for my truck and it keeps the stupid people from getting too close. The air horns are extremely loud and they wake up the dead that are stupid on the freeway.
This is an ideal setup. Very well done.
Thanks!!
That's solid work.
Thanks!
Nice job brother!
Thanks!
Nice mounting job. thanks for showing your setup up close and detailed.
Glad you found some use from it. Thanks for the comment!

How are those compressors mounted to the truck? that is a clean install. What mount did you use to make that look so nice?

Like this.. (that "to keyed power source" is the upfitter switch) drive.google.com/file/d/1_KB97ybsPiOnU8YIlKnEMNruk-E_9sk4/view?usp=sharing
How has the relay held up being mounted there?
It's been fine where it's at. Seems that it's high enough that nothing really gets on it. I don't do any mud bogging or anything like that so it seems to do fine. The pressure switch has died on me once though from moisture and I just replaced it. Was like 15 bucks or so I think for that.
