Wiring of the OBD2 connector?
Anyone know the way to hook one of these up? This is what I've found on it so far but I just wanted a second opinion before I do it.
PIN 2(PURPLE, some diagrams stated it's GREEN) data from pin 58 serial data.
PIN 4 (LT BLUE/BLACK)ground
PIN 5 (DARK BLUE)ground
PIN 16 ORANGE/BLACK)power at all times.
It just didn't sound right to me, it seems like there should be more than one wire going to the pcm and why would there be two that go to ground?
