All you need to do is to break one of the connection to the 806-157 pressure switch.

Btw, we already discussed this. I tried that with 2D, but it didn't meet my expectations. At low IDC (i.e. idle or low RPM) the water jet istead of producing mist was just dripping water. So be careful when turning on the w/i while cruising - if the jet is not producing mist, the poured water might puddle, etc. bad things might happen after that.
Richard, any new solution on this? I was thinking in the future when I get an aftermarket ECU. Instead of using the air pressure switch of the 2D kit for activating the w/i to use the ECU for that. Instead of intake manifold pressure the W/I will activate when the fuel injectors IDC is above 35%.
Any comments about my plan to trigger the water injection IDC based instead of boost based? I wonder why the 2D doesn't have this option by default - since it already monitors the fuel IDC. It would have been much simpler to have some variable resistor on the 2D box to be able to adjust at what IDC to activate the W/I. Even the install would've been simpler - lack of two wires and the intake manifold pressure switch. Richard, have you done any similar experiments?
