I would like to power the injectors from the battery buss. Looking at Z-19, do I need to install a complete switch and diode system for the injectors like is done for the fuel pump and ECU, or can I tie on to the fuel pump OR the ECU system after either the switch (add a separate diode) or after one of the diodes? There will be the two DPDT switches to disable the primary and secondary injectors after this connection. My panel is becoming somewhat switch festooned and I would like to keep more switches to a minimum. How have you guys accomplished this? Thanks. Bill B
