I installed my vpc/safc's rpm wire into pin 58. That's the pin that the TT guys use. But I was reading the NA OBDI write-up and it says to use pin57 as the rpm wire. I dunno which one to use really. I've already wired it into the ecu and I'm not sure if it even matters.
I also have my 2-step turbo timer into pin58 and that seems to work. What's the diff between 57 and 58?
