I have a white Rodgers Emerson Electric control board on a York furnace. Model 50a50-241. York 031 01266-000. How do I get 24vac to a thermostat that requires this? Is there a terminal on the board that I can tap? Does it matter if it is already in use?
Thank you:)

OK, so since no one decided to help me I'll answer it myself. I figured out there IS a terminal on the unit for the 'c' wire. On this particular unit it is marked 'thermostat'. Thanks for nothing askmehelpdesk.com!
