Not sure about JDM, but on USDM the A/C clutch wire is black/red (although same connector as you're showing). The mating connector is on (E) harness (battery to starter) near the strut tower. you can try looking for mating connector near that area, assuming it didn't break and fell off.

what if battery was moved to hatch. There's a single wire jerry rigged that goes through firewall loom.
Normally battery relocation should not affect it.
A/C clutch wire comes from X12 connector (big gray one), you can trace it and see if you can find an unplugged single connector.
