Triggering 2nd fuel pump Pro-m efi
So, I have a dual external fuel pump setup. I want to hook one pump up to a separate relay and trigger it via one of the programmable outputs when i'm above a certain load. I think I have it figured out on how to trigger on/off the pump but, i'm not sure what the difference between "active high" and "active low" is. Can someone explain this? Also, i'm thinking that I need to connect the output wire to the 12v switched input on the relay. Thoughts?
