I have the 421-page Assembly Manual from Millenium Industries. What kind of control is shown on page 399? I can't read the title line, but I know someone here knows what this is. (Looks like an air-ride control, or A/C control...or maybe it's a vacuum-operated 8-track player!).

Thanks in Advance,

 

Figured it out. It's the A/C control (35C60).
