**Twin Turbo 67 Dart Project**

I am going to wire the fuel pumps as follows.

1 Pump will be used as the main pump but all 3 relays will be activated on the HOT side when the ignition is turned on. The 2 Auxiliary Fuel pumps will just need ground to the relay to turn them on. I will use 1 of the spare trigger wires in the MS3 Expansion Board to activate them with 2 set values. 3000RPM or 2PSI of Boost the Hysteria setting will be .50 PSI for them to shut off. This is the most fail safe way to wire these so if Over Boost or Rev Limiter etc gets activated it will cut all the pumps from fuel at once! If for some reason I run short of fuel using 1 pump as the main, I can easily have 2 pumps as the mains and have the 3rd one kick in say at 4000RPM or say 6PSI of boost or whatever. I will be separating the 12V Feed Line into 3 Separate Fused 20 Amp Circuits straight off a Battery Feed. I have the Relay board done complete and just need to add the other 2 Circuits and it will be Dunn like Dinner! haaaa
