BGarofalo Posted July 23, 2016 Share Posted July 23, 2016 I'm going through this Mack I bought and there are 2 switches that are factory that I'm not sure what they do. I figured rather than trace wires I would just ask. Both are located next to the PTO throttle and both light up but don't appear to actually do anything. Any help would be appreciated.
