like jkh says need more info. are you sure you have the correct job print? this could be confusing you. i see one print that has the relays you say, but also has a AF relay that causes the car to pick su or sd depending on the fire service landing for main or alternate.
on this print fsh n/o relay contact feeds af n/o, n/c and then heads to su sd circuits. it is a fairly easy circuit you could pull the su or sd coil wire, and then use meter to work your way back and see where the voltage is coming from. dover contact count is 1-4 left to right from the back. if you are not sure about print, you could always trace coil circuit wiring from the su,sd coil and see if it corresponds to the print
