2d system on 94 RX-7: pump running continuously?

[scl]

Well, I checked the water manifold pressure switch (next to the pump) and discovered that a grey wire from the loom has broken free of the switch. There is one black wire and one grey wire connected to the water pressure switch. Based on the wiring diagram, the broken grey wire needs to be soldered back onto the water pressure switch at the site of the existing grey wire. Does this sound correct? It seems as though this should fix the problem, as believe this means the pressure switch has been deactivated due to the disconnected grey wire. Thoughts?

Thanks,
