I used a timing tuner with a window switch with wot switch for the first stage and a window switch for the second.
fjo and others have window switchs with first gear lockout, delay and stuff
you could have that little hidden switch in the dash like Torettos red car in the first fast and the furious. that way when ur done changing your 10 gears, if your loosing you could spray um
