Default Obd0 Pin out

I've seen two different pinouts. If you are facing the plug side of the ecu with plugs A B and C pluged in (you are facing the side of the plugs where the wires come out), is A1 on the top left or the top right?

Like this: A1, B1 and C1 on the top LEFT


Or this: A1, B1 and C1 on the top RIGHT

90Pray: I see that as being code 43 which is Fuel Supply system. I had to watch the last part to get the whole code. 0:21 - 0:31 is code 43.
