2008 Ranger (B4000) A/C PCM Ground wire

2008 Ranger (B4000) A/C PCM Ground wire
I've got a 2008 "Ranger" (Mazda B4000), 4X4, 4.0L on which I can't get the A/C system to work.
What has been done / tested so far
- All fuses are good
- A/C Compressor clutch relay switch is good
- Has the A/C system flushed and refilled : pressures are perfect
- HP and LP cutoff switches are in working condition
- I've jumped the relay switch and the clutch kicks in and the A/C system provides cold air, so the clutch and compressor are good
Now I have no ground coming from the relay comtrol terminals, and I do believe that ground is coming from the PCM-ECU, probably a broken wire, but which one...?
That's why I request your help to help me identify this wire with a PCM/ECU wiring diagram.
Help would be greatly appreciated as the hot weather is lurking in.
