1992 240 AC wiring issues

[1992vt240]

Hi, just working on a new to me 1992 240. Looks like at some point the old compressor failed and the wiring was cut off to keep it from running and blowing out the rest of the system. Now trying to get the ac up and running with a new compressor and the hot wire is nowhere to be found. Does anyone know what harness the compressor hot wire originates from? Asking on behalf of the guy working on it, not an ac/wiring expert myself, so please excuse if my wording isn't quite right. Thank you!
