Many off-roading enthusiasts have heard about the Rubicon locker, a popular modification for their Jeep Wranglers. This locker is known to improve the vehicle’s off-road performance by providing better traction and stability, especially on rough terrains. However, installing a Rubicon locker can be a daunting task, and it requires proper wiring to function effectively.
In this article, we will provide you with a comprehensive guide on how to wire a Rubicon locker, a compressor, and an optional switch. We will also discuss some frequently asked questions to help you understand this process better. So, let’s dive in!
What is a Rubicon Locker?
A Rubicon locker is a locking differential that works by preventing the wheels from rotating independently. It forces both the wheels on the axle to spin together, providing better traction and stability. This is especially helpful when you’re off-roading and need to navigate challenging terrains.
However, to install a Rubicon locker, you need to make some wiring modifications. These modifications include wiring the locker, compressor, and a switch to control the airflow.
The Components You’ll Need
Before you start wiring your Rubicon locker, you need to ensure that you have all the necessary components. These components include:
| Component | Description |
|---|---|
| Locker | The Rubicon locker itself |
| Compressor | The air compressor that powers the locker |
| Solenoid Valve | A valve that controls the airflow to the locker |
| Wires | Electrical wires for connecting the components |
| Fuse Holder | A device that holds a fuse to protect the electrical circuit |
| Switch | An optional switch to control the locker |
| Relay | A device that controls the electrical flow to the locker |
| Fuses | The fuses that protect the electrical circuit |
Once you have all the components, you’re ready to start wiring your Rubicon locker to your Jeep Wrangler.
Wiring Your Rubicon Locker
Step 1: Mounting the Components
The first step is to mount the Rubicon locker, compressor, and solenoid valve. Here’s how you can do it:
- Mount the locker onto your Jeep’s differential, following the manufacturer’s instructions.
- Mount the compressor in a secure location, preferably under the hood, using the provided hardware.
- Mount the solenoid valve near the compressor, using the provided hardware.
Make sure all the components are mounted securely and won’t rattle or shift during operation.
Step 2: Wiring the Locker
To wire the locker, you’ll need to connect the locker, compressor, and solenoid valve. Here’s how you can do it:
- Connect the locker’s electrical connector to the solenoid valve.
- Connect one of the solenoid valve’s wires to the compressor’s positive terminal.
- Connect the other wire from the solenoid valve to the locker’s electrical connector.
- Connect the compressor’s negative terminal to a good ground on your vehicle’s frame.
Note that the color of the wires may vary depending on the manufacturer, so be sure to check your locker’s manual for specific instructions.
Step 3: Wiring the Compressor
Now that you’ve wired the locker, it’s time to wire the compressor. Here’s how you can do it:
- Connect the compressor’s positive wire to a 12V power source using a 30-amp fuse.
- Connect the compressor’s negative wire to a good ground on your vehicle’s frame.
You can use a fuse holder to protect the electrical circuit from any potential shorts or overloads.
Step 4: Wiring the Switch (Optional)
If you want to control your Rubicon locker using a switch, you’ll need to wire it as well. Here’s how you can do it:
- Mount the switch in a convenient location, such as on the dashboard.
- Connect one of the switch’s terminals to the solenoid valve’s positive terminal.
- Connect the other switch terminal to a 12V power source using a 5-amp fuse.
Make sure to use the appropriate fuse size for your switch and wiring.
