So I just finished up the wiring diagram and I think I have set up how I want. I have seen people say you do not need a relay for the solenoids for positive from battery with the NOS mini since it’s basically the grounding switch, I have the relay set up on my wiring though bc I want the fuel pressure safety switch to be able to cut off the power to the relays if for some reason pressure drops from low or no fuel or failed fuel pump.
I also repurposed the heater switch to be the trigger for the 2 step/rpm limited just for fun to make noise and maybe shoot flames!
