So if I understand correctly, you put a relay with a switch connected to the injectors fuse?

Yes, the fuse tap thing is plugged into the slot for the injector fuse. The relay is a 5 pin, power from the tap feeds pins 30, and 86. Pin 85 is connected to the wire leaving the fuse box, going to the normally open momentary switch, the other side of the switch is connected to ground. Pin 87a (the normally closed output) is wired back to the fuse taps lower right slot to send power to the injectors. Pin 87(normally open output) is not used.
