I'm in the process of rewiring my OBDII connector after a STI v7 jdm swap in a Legacy GT 99.
I can log no problem, but right now I can't pull out the rom (read ) or write anything.
I was wondering if it is because I don't have any wires going to pins 9 and 15 of the OBDII connector. On the tactrix cable these pins are referred as
9: L line (Subaru specific)
15: ISO 9141-2 L line
Can you guys give me more info about the L line?
