I'm currently rewiring my 90 Miata and installing a push-to-start button to replace the key cylinder and go completely keyless, because racecar. The way it will work is there will be two separate switches, first is a toggle on/off and the other will be a momentary switch. The on/off will activate the ignition circuit, and then the momentary is held and fires the starter. I'll have to deal with the ignition lock as well to be completely keyless but that's mechanical.
I'm an amateur when it comes to wiring. I have experience with basic audio wiring and such but did a lot of research and reading to try and draw this up. I was just hoping to get a second opinion on my diagram as well as make sure I'm reading factory wiring diagram correctly.
I included a pic of the wiring diagram for the ignition switch. I drew up the diagram that includes four relays, 2 SPDT and 2 SPST, but I feel like it could be done more efficiently and I also want to make sure my ground leaving the coils of the relays won't short the whole system and if I should use an external 12v source to tie into the ignition switch.
