Air Suspension Deflate

What’s the best way to completely deflate the bags on the auto leveling suspension? I’m in the process of putting in a spacer and need the bags flat to install. Is there a fuse to pull or a line to disconnect?

That would have been a very good solution. I had the Cornfed kit and instructions didn’t go into detail on deflating bags.

For anyone doing this in the future, what I ended up doing was letting my suspension go to full droop. I then started the truck and set auto-leveling setting to low. Since there is no weight on the axle, the system will keep letting air out until it is basically deflated.
Disclaimer, it will take about 5 minutes for all the air to exit the bag.
It’s still a little tricky getting the spacer in. I suspect if you jack the axle up slightly you can get more air out.
