Explaining My DIY 4×4 Air Locker Setup: Parts, Wiring Diagram, And Demonstration


This is a full walkthrough of my entire offroad 4×4 air locker setup covering the physical location of all the components, wiring, and air parts. First I lay it all out on the whiteboard, then show where everything is located and how it is wired up. I also cover the air compressor, air tank, air regulator and fittings then demonstrate the differential locked and unlocked while up on the lift.

Here is a link to the video where I covered the installation process of putting the locker inside the differential: https://youtu.be/8f1zspWC9ZM

This is how I did it. Post your thoughts in the comments because I’m always up for learning!

Hope you enjoy!
