OBD1 to Serial port, wiring diagram???

[Jimbob GSI 3.0]

Any chance of  wiring diagram so I can make an OBD1 port to fit my OpelScanner, as I can`t find a new one anywhere so I¬m going to have to make one. Need the OBD1 to serial port wiring diagram, so I don`t blow up my Scanner box.

So you only use the 3 cables??
What are the other ones for??
And to save me time with a multi tester, have you a diagram of the OBD2 port to Serial port. As other wise I`ll be there a while!!! LOL.
