P better, can you explain why that is. What "bad things" would happen
P if I did that?

What would happen is you would run the A/C compressor every time that relay
kicked in for the fan. there is an internal connection in the thermostat
between Y and G when the fan is in auto position. if you left it in the on
position it would be OK but that would defeat the purpose of the relay
