Hey all, I'm replacing my pool pump motor -- installing a Century STS1152R in place of the original AO Smith Century 1081. I was told the 1152R was the replacement model. On the original 1081, there were four wires: Green (ground), Red (which went to "Line 1"), Blue (which went to "Line 2") and Black (which went to "Line 3"). The new motor has spots called L1-High, L2-Line and A-Low and ground. Any idea how those correlate to the old ones? Is black the right one to connect to L2?
