you need to find the wire from the ECU to the injectors then you can duplicate my switch. check Honda forums for a master wire diagram set (my matrix forums had one for me) and start looking for the wire you need.
try this diagram:

you want to add your relay in line with the yellow/black wire after it combines the injectors but before it merges with anything else.
