Detroit 60 fan clutch setup

Hello all

Can someone with a Detroit 60 in their International help me out with their fan clutch setup? My fan has been locked on since I bought the truck. Runs fine but I want the fan to work correctly as winter approaches.

I have an air line that's sitting on the top side of the engine that's going nowhere (has been cut off after a solenoid connection) but I'm not sure what goes where. I will try to post pics but I'm not sure I can (can't remember if this forum lets me or not).

I have an 1993 International 8300 with the 11.1L. If someone has a manual for these, would really like to see the relevant pages on the fan. Thanks!
