    here's a lame ascii art....
    some cars have a B, some don't etc... this is just an example.
    obd0 and 2 are differen't.... but since i see a 5th gen coupe, here's what a basic obd1 ecu looks like. the letters are just examples... i'm too lazy too look up and verify that there is no B plug...

    Code:
    |---------------------------------------------|
    | A1 A3 ... | c1 c3 ... | D1 D3 D5 ... | 
    | A2 A4 ... | c2 c4 ... | D2 D4 D6 ... |
    |---------------------------------------------|
    
    now remeber, some obd's don't have a C plug and all that... but basically, it goes left to right abcd...
    and goes numbers like i did above.

    obd2 is different. they have 3 or 4 rows sometimes
