Ok had an engine swap everything seems fine 98 legacy gt to 04 wrx 2.0t engine / drivetrain and ecu ... but i cannot access the ecu via the diagnostic port with my tactrix cable.. i'm guessing wither the diag port was not hooked up, anyone have any info on what wires from the ecu go to the diag port on a 04 wrx? or can i just pin directly from the ecu?
Any Help would be great, ideally i would like to direct wire it to the ecu
Thanks
