I have been asked to wire a septic grinder pump for a new house. I am looking at two cords coming out - one with 6 wires # 12 - (black, red, white, orange, blue and green)and the other cord has just 2 wires # 14. The pump is a 2HP, 230V. There is .9 ohms resistance between white and blue and white and black. There is a 2.2 ohms reading between black and blue. All other readings are OL or in the megohms. My take is that the cord with two small wires is a moisture sensor (?) and .9 ohms between white and blue would indicate L1 and L2 (?) but what about the other 3 wires red, black and red (obviously green would be for GND). Tank is filled up with rain water and there is no paperwork. Can somebody help me with this? Tx
