If I remember correctly the stat gets its power from the control board on the front A/C.
Lots of screw nuts and cheap connectors under the A/C that goes to a junction box, the stat, pre-wire for garage A/C and the bedroom A/C.

Front AC has 1 comm cord, main AC has 2 but all connections look good. I'm sure it's in the comm cord, I just spent $450 getting the bed jacks rewired

Your thermostate should get it's power from the furnace, it would then send the signal to which ever unit you are useing.
