Quick Air 2 - Under the Hood Install

One of the best ways to significantly improve your Jeeps performance on the trails is to air your tires down. Lower air pressure will allow your tires to have a greater foot print which will give you a lot more traction on sand, snow and rocks. The only real problem with this is that once you get back on pavement, you will need to air them back up. When you're riding on tires 31 inches or taller, filling each one back up to 30± psi from 10 psi can take forever. That's why I choose to invest in a Quick Air 2. This compressor is fast, small and powerfull enough to reseat a busted tire bead (I have personally done this).

A few years back, I purchased a portable version of the Sun Performance Quick Air 2 air compressor so that I could use it in either my then 1998 Isuzu Rodeo or my Jeep TJ. Needless to say, I no longer own a Rodeo and so I decided to find a way to hard mount the compressor in an effort to save valuable space in my Jeep.

Please note that this write-up is based on a portable Quick Air 2 unit and the installation of a hard mount unit will most likely be different. If I could hazard to guess, installing a hard mount unit would be easier.

What You Will Need

• Sun Performance Quick Air 2
• 13mm Socket/Wrench
• Ratchet
• 6" Ratchet Extension
• Center Punch
• Hammer
• Hand Drill
• 3/8" Metal Drilling Bit
• Solderless Ring Terminal (3/8" Ring)
• Solderless Terminal Crimpping Pliers
• Zip Ties

Installation

1. The easiest way to work under your hood is to open it all the way and resting it against the top of your windshield. Placing a rag or something soft and padded here is a good idea as it will prevent any damage to your paint.

2. Go to the driver side of your Jeep and remove the 4 bolts securing the auxiliary tray using a 13mm socket.

3. Place the auxiliary tray on a workbench and then place your Quick Air 2 on top of it as shown in the pic to the left. Carefully located and mark off the location of all the bolt holes on the mounting plate using a center punch. I was only able to mark off 3 total.

Hard Mount Unit Install Instructions: If you have a hard mount unit, I would venture to guess that you should be able to mount the compressor directly to the auxiliary plate. In this case, I would mark off all the holes on the Quick Air mounting bracket on the the auxiliary plate using a center punch. From there, you should be able to drill holes and then bolt up the compressor to the plate and re-install.

4. Using a hand drill with a 3/8" metal drilling bit, drill out the holes on the mounting plate you just marked off.

5. Back under the hood, bolt the Quick Air 2 compressor directly to the auxiliary tray's mounting bracket minus the tray.

6. Take the positive and negative leads from the compressor, route it along the wiring harness attached to the firewall and zip tie them into place.

7. If your wires do not already have them on the ends, affix a solderless 3/8" ring terminal to each end now. Then, attach the leads to the positive and negative bolts on your battery.

8. Flip on your Quick Air 2's switch to make sure it works.

That should be it! Please let me know if you have any questions.
