This has been one of the coolest projects I've done. Everything was made from parts and scratch, no pre-made harness or anything. Did 2 compressors that automatically kick on when the key is on using relays that also auto shut off when the tank hits 200 psi. I also did a 2 sensor digital display for the tank psi and the airbag psi. A switch in the cab let's you go up and down when ever you want. The speed for airing down is also adjustable with a nozzle at the end. Theres alot of wire in this truck! The right 2 ports were left free for a future train horn also. Thanks for having me do this project Jake! Videos are in the comments.
