This is a guess. But the T-stat runs on 12 volts.
NOW.. That might just come from the FURNCE and not the A/C
If so, that's your problem, You removed the T-Stat Power Source
There may e a way to fix it but here is a suggestion
you had two blue wires on that furnace, One of them was 12 volt + the other was the return from the T-Stat
Obtain an automotive test light.. CLip it to a known ground and search for a good 12 volt source (Bright light) now clip it to one of the blue wires (Heck oth of them even and touch it to the 12 volt source, See if A/C now works
IF it does, get a license plate lamp socket (Wedge base) and bulb and make those connections solid.. The lamp will act as a self-reseting breaker if any shorts happen. I use that same system elsewhere in my RV.
