Sudden fuel pump issues

Hey fellas, I'm having some problems with my fuel pump. It's shortage out somewhere, because it works and then I'll shut it off and it stops workin. If I wiggle the ECM connection it runs again. So imma assume that it is a faulty/loose wite that needs to be fixed. Its not the fuses, they've been checked. First question is, does this happen to anyone else? And second and more importantly, which wire(s) run the fuel pump? This way I can save some time and patience and go straight to the wire thats causing the problem. Thanks fellas

I hate two faced people...I'm never sure which face to slap first =P

The signal from pin A8 of the black ECU connector goes to the Br/Bl wire of the fuel cutout relay coil.
This energized the fuel cutout relay allowing current to flow via the Br wire to the fuel pump.

Wow, didn't actually expect a detailed answer like that, most of the local shops had no idea. I appreciate the help, you really know your stuff
