    You can use two water solenoids part number 4340 with one water injections unit part number 4259. Just run the two activation wires to both of the solenoids.

    When the enigne is runnig is the green light pulsing? if not there is a good chance you are not getting a trigger signal. Check the white wire you connected to the spark plug wire.

    Thank you
