Boost trigger

If you hook the blue wire up as shown, you can change a jumper on the control board, on the left side, from IDC to MPS. This allows you to trigger the system at a specific boost point instead of an IDC point. For example, you can set the system to start spraying at 5psi, then inject on IDC after. The trip/trigger pot is now used to set the boost point at which you want to inject.
