I need the schematics for a goodman nonprogramable thermostat. I'm putting in a honeywell programmable and the wiring isn't the same

If you give us the color of wires and what letter they go to on the old thermostat we can walk you through it. Turn power off to unit before removing cover on T-stat so you don't blow a transformer or low voltage fuse.
