I am in the middle of setting up my WFP system. I am at the stage of wiring the pump and controller in, I have got 4 wires from the controller (Red, Black, Blue and Brown). My pump is a 100PSI Shureflo. I have the Red from the controller to positive feed. I have the Black from the controller to earth. I have the Black from the pump to Blue on the controller. And the Red from the pump to the Brown from the controller. Now is this the correct way around as I seem to have constant power at the pump and the controller doesn't turn the pump or off when holding the "ENTER" arrow and neither is it controlling the flow rate when pressing the up/down arrows.
