Q: G5 Quad Delphi 4 wire Pump Connections ?

Hi,

I am trying to test the coolant pumps on my g5 because one cpu is overheating and there are no coolant leaks, there are 2 Delphi pumps each with 4 wires, they are connected to a black 12 way plug.

I am wondering if I can connect a 12v supply to the pumps to check that they function ok..

If anybody knows what the 4 wires are on the pumps I would be most grateful..

Thanks In Advance

Acestu
