fuel pump control I'm just about to wind up my LS1/ RX7 conversion. I read in another thread the PCM fuel relay control is active high. I need a ground to turn my RX7 relay on. I assume I need to use the fuel pump enable signal then. Does it switch on / off at the same time as the fuel pump control signal?
Also- dumb question. What is the shift pattern for a T56?

probably easier to reconfigure or replace the rx7 relay with one you can trigger hot. then you could use any wire that goes +12 with the ignition on (though you wont have a timed prime pulse.. it will just stay on)
the pattern is 1 up left 2 down 3up right 4 down 5 up right 6 down and reverse up and way right.

cut the power wire for the relay... stick it to ground... run the wire the from the old fuel pump turn on to the PCM.... simple.
(athough swap that the other way around if your relay has polarity... i havent ever come across a automotive one that was, but i never messed with RX7s... i dont fit in them
)
