Ok,

just wanting a little clarification:

NC = no connection????

I see in the power point, there are 3 wires off the molex connection, however, it is circled "4 wires used".

the diagrams show 4 items:

12+
NC
ACC
GND.

the NC in the pin out diagram says it is a ground on the pump.

I only have 3 pins that came with the connector.
