Question about Honeywell Electronic Programmable Heat/Cool Thermostat - CT3300A100 Heater
Buy some more thermostat cable with the same number of conductors inside it that you need. Twist the wires in the wall to the conductors on the new cable you just bought. Wrap the connections with electrical tape and pull the new cable with the old cable, starting at the furnace. You will then have all brand new conductors to fit to your new thermostat.
