    Finally getting around to doing a write-up on this. It's been completed for a few months now. Atleast this way I can give a little feedback on the functionality:D

    Compressor: From seller SafeVehicleProducts on eBay. Evidently he's not selling compressors anymore but its identical (specs and looks) to the VIAIR 350C. 100% duty cycle with ~1.2cfm. Although it states it's 200psi capable, I won't ever need to drive it that high.

    Tank: VIAIR 2.5 gallon 200 psi tank. VIAIR 2.5gal tank The perfect size to fit in the spare tire cavity

    Wiring: 10 AWG since wiring long runs

    Hose: 3/8" ID hose (from Lowe's)

    Fittings: All types. These things suck to find and plan for. They are never as cheap as you would want them to be either. I did find some quick connect couplers that I like though. They are made by Legacy: Legacy ColorConnex couplers

    And lots of other miscellaneous stuff.

    On to some pictures:

    Started by finding a place to mount the compressor. I've seen this done before and it was the best place I could find to put it. Where it would be mostly protected and would be in my way under the hood.

    IMG_6494_bdc2be5b7732d9800b132e636ba0e6d9f2bf5f63.jpg

    And back in the truck:
    IMG_6496_2f1929892519289222695ffa46bb5b5896e16084.jpg

    Wired in the relay:

    IMG_7458_b4867d81bcb3831f5aad41830e8ac413f0d0450d.jpg

    Needed to find a place to put the switch, so I came up with this location. I actually like the location alot. Can't be seen from the rest of the vehicle's seats so it's kinda stealthy, atleast until you open the driver's door.
    IMG_7462_a0cfb56f9fc60e82b1ed1f2f6255e36752a8ee8a.jpg

    IMG_7461_811bff37cfcfb77400a330f10743448158c5fab2.jpg

    Now I needed to mount the tank. Removed the spare since that is really the only place, besides the bed, that can handle a tank of useful size. Fabbed up some brackets of 3/16" steel, and it mounted up easily. It's tucked up out of the way but still easy to get to for draining.
    IMG_7465_99a648d3bd4ce7559b76afb808f1dc6970e1a665.jpg

    IMG_7467_e3bb4a66d90b83b3cd4c00b9edd029fc12aa58d0.jpg

    IMG_7470_34e85dfed08f9a6a2ff00737fc953025a408fa0b.jpg

    Can barely seem them in the picture, but I cut some spacers (white in the picture) that mount between the tank and the bracket on the drain side. This is so that the moisture will make it to the drain. It's a very slight angle. The spacers might be 1/4".
    IMG_7480_86ae4cac9376da6668362bf45f0c1cd1d0094927.jpg

    Now the business end of the system. I fabbed up yet another bracket to hold a manifold in the engine bay. It mounts to the pre-tapped holes in the fender. Manifold is 2x 3/8", 3x 1/4"NPT. The 3/8" in comes from the tank in the back, the 3/8" out goes to my horns, 1 1/4" goes to the regulator, 1 1/4" goes to gauge, and the last one is capped for now. This setup has worked awesome so far. Oh, the black thing on the end of the coupler is just a little rubber cap to keep dirt out.
    IMG_8541_35aca1d028132b962c0241c4cb4042375d51f9bc.jpg

    IMG_8543_93cf9c6191c25f1d519d7dc4571f80af38ca8ea6.jpg

    IMG_8542_2d1d2ba841ea3f0efba0aee2af4f6ebc0a7138a4.jpg

    The air pressure gauge inside the cab is from GlowShift: GlowShift gauge Honestly, the gauge is cheap. The bezel is flimsy and easily dented, the wiring is silly, and overall feel is a 6-7/10. Haven't tested its accuracy though. It's an OK buy for an inexpensive gauge, but if I were doing multiple gauges, I would probably invest in a little more well built unit. The color adaptability is a nice feature though.

    So you'll notice that the gauge is tilted here. That's because I'm still working on my pillar pod and the fit is really tight with the gauge. I'm living with it for now.

    IMG_8553_c7c91a782cf75796e54c29fde83c262eb99e1dbf.jpg

    That's it for now. The system has been used several times. I've aired up several tires and used the blowgun with it several times and it has performed well. Don't have times though. I haven't run any air tools with it, mainly because I don't own any, but I plan to test some out on it.

    That's it for now. Let me know what you think!

    Looks nice. Good writeup.

    Where is your spare going to go? Does it end up taking more space than the air tank would have?

    Nice write-up, thanks for taking your time. Onboard air system is on my list of things to do, but will have to wait for now. There are a lot of things I would like to do first

    Thanks guys! Hopefully it will be of use to someone in the future. That's why I take so many pictures! I always need more info than I can find it seems.

    Since you asked...Custom tiregate build :D

    So nope, doesn't take up any of my bed space. Before the gate, I had the spare in the basket on top.

    Yep, through one of the rubber grommets. Sealed it with some RTV. Then along the frame bundled up in some loom.

    Did you run the power wire for the switch and the compressor through firewall that leads to the engine bay? I ask because I can't find a way to wire something from the bed and have the wires directly lead to the engine bay

    The switch in the cab only activates the relay. I'm pretty sure I ran the power wire up the inside of the fender, keeping it away from any hot surfaces, and loomed it ofcourse. It's been a little while since I did it! Haha, I'll have to check and make sure, but I'm about 98% sure that's what I did.

    From the picture it looks like when you rear squats it might hit the tank? Or is it just the angle of the picture?

    Just the angle. It's away from the axle enough to where it wont hit. I'll try and get some more pictures of the clearance.

    Any updates on how well this works? I have a different mounting idea, but this is the system that I would like to run.

    Can't you just run a pressure regulator relay? That way the pump just comes on when the air pressure gets low to a certain point? I would think that would be better than running a dedicated switch no?
