Sam!
I always prefer to feed the
whole system via a master relay. This means you can use low current signals to control the main power feed relay for the nitrous system.
You can use it as you have suggested. But I always go for the safest option that wont put any undue load on my original components should something go wrong or short out etc. My cars electric system is now 35 years old
My main concern with my system is making sure that everything shuts down if my fuel pressure drops too low.
I'm running 250-300hp of nitrous on my old MGB. So I dont want any more melted / cracked pistons in the collection of 12 that I have at present
Maybe I'm being too fussy? I dont think so!! Lack of petrol with the nitrous flowing = trouble!
Your controller will handle the load of the pulsoids with no problems. I just use the master relay as my failsafe.
On modern cars, the fuel delivery system is more reliable than mine. So its not as likely to go wrong. But I have been on the wrong end of 200hp of gas with no petrol a few times now. And that was due to fitting crap fuel pressure switches. Trevs switch has saved me engine damage 3 times in the last 18 months.
Just try what you have mate. The wiring diagram looks ok to me.
