electrical connection

[swing]

I was wondering if anyone has hooked up a firestone electrical compressor. I have a 2013 Chevy Silverado 3500 and would like to install air bags on it with the electrical compressor but I need to hook up a 30amp electrical connection to an accessory side on the fuse box but have no idea on where to hook into the electrical system for this system so it activates when I turn the key on. any help would be appreciated.

find the relay center(or anyother fuse block that has good size flat male terminal) and using a test light find a terminal thats on with the key on and off when key is off ,,,,put in the inline fuse and carry on ,,,

 

not hard to find at all,,,,,,

On those trucks there is a stud that is in the underhood fuse box toward the front that is intended for these kinds of accessories. I use mine for accessories like that, look in the manual it is listed.
