How to Install an ARB Air Compressor Step-by-Step

Getting Your ARB Air Compressor Installed: A Step-by-Step Guide

Installing an ARB air compressor is a rewarding project. It brings the convenience of on-demand air right to your fingertips. We’ll guide you through the process. You’ll have your compressor ready for the trail in no time.

Pre-Installation Checklist: What You’ll Need

Before you begin, make sure you have everything. Having your tools and parts ready saves a lot of time. It also prevents last-minute trips to the auto parts store. This ensures a smoother installation process.

Essential Tools for the Job

You won’t need a whole workshop for this. Basic tools will get the job done. You’ll want a good set of wrenches and sockets. A drill and drill bits are also necessary. Don’t forget wire strippers, crimpers, and a multimeter. A torque wrench is highly recommended for certain connections. Safety glasses are a must, always protect your eyes!

Components Included and Additional Parts

Your ARB compressor kit typically includes the compressor itself, a mounting bracket, and wiring. You might also find a pressure switch. Check your kit against the manual. You may need to purchase additional items. These could include airline tubing, fittings, and a fuse holder with the correct amperage fuse. It’s also wise to have some electrical tape and zip ties on hand. These are great for keeping things tidy.

Choosing the Right Mounting Location

Where you mount your compressor is important. It needs to be secure and protected. It should also be accessible for maintenance. Consider the airflow around the unit. Compressors can get warm during operation. You don’t want to stifle its ventilation.

Factors to Consider for Placement

Many enthusiasts choose a spot under the hood. Others prefer a location in the cargo area or under a seat. Think about how you’ll run the air lines and electrical connections. Some common locations are near the battery for easy power access. Another popular spot is the engine bay, away from excessive heat and moisture. Research found that a well-ventilated area is key to longevity.

Protecting Your Compressor

Try to avoid mounting the compressor in a place where it could get directly hit by water or debris. While they are robust, keeping them clean and dry will help them last longer. If you’re mounting it in a less protected area, consider using a protective cover.

Wiring Your ARB Air Compressor Correctly

This is often the most intimidating part for DIYers. However, with a little patience, you can wire it up correctly. ARB compressors are designed to be wired directly to your vehicle’s battery. This ensures they get the power they need to operate efficiently.

Understanding the Wiring Diagram

Always refer to the specific wiring diagram that came with your ARB compressor. It’s your roadmap for success. Most setups involve connecting the compressor’s positive wire to a fused power source. The negative wire typically connects to the vehicle’s chassis or battery negative terminal. A relay is often used to protect the compressor’s switch from excessive current.

Connecting to the Battery and Fuse Protection

You’ll want to connect the main power wire to a heavy-duty fuse holder. This holder should have a fuse rated appropriately for your compressor model. This is a critical safety step. It prevents damage to the compressor and your vehicle’s electrical system in case of a short circuit. Many experts suggest a fuse at least 30 amps, but always check your manual.

Using a Relay for Optimal Performance

A relay acts like an electronic switch. It allows a low-current signal to control a high-current device. In this case, it allows your dash switch to activate the compressor without carrying the full load. This setup prevents overheating of your switch and wiring. We found that using the included relay harness simplifies this process considerably.

Making the Connections Secure

Use proper crimp connectors for all electrical connections. Avoid just twisting wires together and wrapping them in tape. This can lead to loose connections and potential problems down the line. Ensure all connections are tight and insulated. This will ensure reliable operation.

Testing Your New Air Compressor

Once everything is wired up, it’s time for the moment of truth! A thorough test ensures everything works as it should. This prevents you from finding out about a problem on a remote trail.

Initial Power-Up Test

Turn your vehicle’s ignition to the “on” position but don’t start the engine yet. Flip the switch for your air compressor. You should hear the compressor start to run. If it doesn’t, immediately turn off the ignition and double-check all your wiring connections. Use your multimeter to check for voltage at the compressor.

Running the Compressor and Checking for Leaks

Let the compressor run for a minute or two. Listen for any unusual noises. Check for any air leaks at the fittings if you have an air tank or tire connected. Many ARB kits come with a quick-connect fitting. You can attach a tire chuck to test pressure. Ensure the compressor can build pressure effectively. We found that letting it run for a few minutes helps seat the seals properly.

Final Checks and Tidying Up

Secure all wiring with zip ties. Make sure no wires are rubbing against any moving parts. Double-check that your air lines are routed safely and won’t kink. Ensure your mounting hardware is still tight. A final inspection will give you peace of mind.
