1st post here!

Been in the process of restoring the 6pi and vdi system on my brothers 1990 s5 rx7. I have everything necessary to get the systems to work, but the previous owner cut the connectors that send the rpm signals allowing air pump pressure to pass through the solenoids to then go to the 6pi / vdi. Was hoping someone could show me what wires send the rpm signals and I could get it all functioning. Thanks everyone!

 

welcome to the board.

until someone else comes with more pointed knowledge/experiences with this, you can start with the FSM in the meantime.

you can get a copy here: Foxed.ca

 

black and white wires = constant 12v (1 wire for each)
blue and white wire = 6pi
black and yellow wire = vdi
