With the 95 OBD I cars, you should not need that Black box that the hahn kit comes with. Assuming that it is the fuel cut defencer you are talking about, that is for the OBDII cars, because when their ECU sees a voltage above 4.7 volts coming from the map sensor, it cuts fuel which can be bad for our cars...and it will run like ass...
but you are in luck. you got a 95..just like me. You shouldn't need any kind of fuel cut defence. I still have my check valves in mine, because the kit i got had the map sensor already put together with them I am gonna try taking them out real soon, but others have done it fine without any kind of defense on the 95. Our ECU doesn't freak out under boost.
As for hooking up your regulator, just disconnect your fuel return line where it comes off the fuel rail, connect one side of the regulator to the fuel rail, and the other side to the return line running back to the tank. Then just connect that vacuum line to a good source.
Hopefully, i cleared a couple of things up for ya...
