how do i install a thermostat to a Goodman air handler? Preferably a diagram.

I have moved your question to a thread of its own. Your question trailed on the end of a guy asking about truck driving and a felony. I'm sure that the people who can answer your question probably would not have see it there.

I know you're new, but please understand that it is never a good idea to piggyback a question on someone else's question.

I take it you have a heat pump? Can you list the number and color of the wires and where they were connected on the old thermostat, not all installers use the same colors. Mike
