Racecraft, if the description about location, of switches , relays and fuses, doesn't help then go with 336muffin's info and call Fleetwood.
Denso and Evans are way different in location, switches and wiring.
So far I've found pressure switch ( only one ) located next to receiver dryer, sending a signal to a relay ( not shown in Evans wiring diagrams, but obviously not Freightliner ) 2 circuit breakers marked A/C with wiring disappearing into 2 different harnesses, one goes the condenser fan ( not shown in Evans or Freightliner wiring diagrams) the other goes through the fire wall, and I haven't been able to track it to the control. I hope my system never gives me trouble because it'll be a headache to figure out.
As to the A/C lines being , Evans , Newmar or Freightliner , I'll re-new my password and see if they come up with Freightliner part numbers on-line, I'll examine them end to end this summer as I replace the heater hoses.
Can't wait to get started on that.
