I'm doing a 94 12v 47rh swap in a square crew cab dually, I think I have everything figured out except what psi switches to use. So heres my plan run two normally open switches out of the gov port for lock up and od, then run a normally closed switch under boost pressure so when you stomp on it it will toss it out of od and lock up then when boost goes back down it will ground and both will work as usual. But what should I get for switches? I think these will work for the od and lock up there adjustable up to 60 psi, but what psi should I shut them off at in the boost switch 10 psi? Thanks

have you considered simple toggle switches in the dash to take manual control over those functions? I had to do that in my 12v 47RH due to bad wiring/PCM issues and seems to work fine.
