My AC wasn't working(not blowing cold air) so I grab some cans of 134a and attempt to add the refrigerant. I notice that the AC clutch isn't engaged either. After about 10 minutes it seemed as though the can of refrigerant was still full. So I pull out my mainfold gauge set to check the pressure and I get 0, nothing, nada. I've read through quite a few posts, but there weren't many dealing with the M119 AC issue.

So far I've bridged the pressure switch and have checked all fuses; still nothing from the compressor.
My biggest question is, how do I jump the compressor? I've seen posts referring to the green/white wire. But on this M119 I can barely see the back of the compressor let alone the wires. I have looked from up top and below.
Thanks in advance
