adapting obd2 to 10 pin opel obd1

[newmedia]

i want to scan an opel vectra A
this model has an 10 pin OBD1 socket

my opel scanner adapter  is OBD2 - 16 pins
I read that i can  adapt this interfaces by using 3 wires

now the problem is what pin goes where ?

[Artur]

16 pin   ---   10 pin

4-5     ->        A
16       ->        F
7        ->        G

16 pin   ---   10 pin

4-5     ->        A
16       ->        F
7        ->        G

4-5 = >  4 and 5 / 4 or 5 ?

[Artur]

4 or 5, both are grounds.
