Which wire supplies 12v / IGN /GND & power stock RX8 EMS/ECU?
 

hey guys, I installed rx8 reluctor ring & sensor to my 20b project to use my stock tachometer. I can't get the tach and power steering to work correctly. After looking at my harnesses, I'm certain that my stock ECU is not getting power from the battery. But even with the wire diagram, I can't figure out which wire to splice power, ign, GND, and the any necessary wires to get power to the stock ECU. could someone let me know? My engine harness is completely cut and hacked, so I need to know which wire(s) from the 5 white plastic connectors from behind the stock ECU to connect to supply power.

i found these to be very helpful for those trying to wire stock ecu without stock harness. now everything works!

Wow --great find--thanks for posting.
