I'm replacing the A/C
thermostat in my 1971 Ambassador 29. This unit had a separate thermostat for the heat. In the process of the rebuild the old thermostat has disappeared.
The four wires (original, I believe) which went to the old thermostat are :
black, brown, red and green.
Could someone tell me how those map to sockets on the new thermostat:
Y (Compressor contactor)
C (24vac common - optional)
G (Fan Relay)
I realize I'm being lazy but I'm still a bit overwhelmed and really don't want to delve into the AC unit now if I don't have to.
Thanks very much,
