At work today I was tryin to diagnose a problem a guy had with his superchips tuner. The tuner was not getting constant power from the OBD 2 port like it should have been to sustain itself. If you turned the key to the On position the tuner would get power and work but as soon as you were required by the tuner to turn the key off it would lose power and restart itself. My question is, does anyone know the wiring order of the port? As in which wire is supposed to have a constant 12v source in the OBD 2 port? Any help would be appreciated, I wanna get this guys tuner workin. Oh and btw it's a 97 Ram 1500 with the 5.9L.
