Thanks for all the input guys, I'm going to try this mod soon.  I am
interested in that schematic though.  Why would you need relays?  As far as
I understand it the positive to the fifth injector is on all the time when
the ignition is on, and the negative is what triggers it to come on.  So if
you have the switch grounding the injector you shouldn't need any relays?!
