I also think that the wire feeding the WOT switch should not be fed via the relay (just the fuel pump)
I don't know about 2 stage N2O systems but do you shut off the first stage when the 2nd stage is activated ? it appears you are. Does the N2O retard have 2 wire activating it, that seems different from ones I have wired




Yes it does shut off the first stage and opens the
2nd via the timer.... and as I said above he is using
the first relay to take load off the switch
