As title states, I do not have a (OBD1) datalink connector (swap) and need to pass ref.

I know that one wire goes to D7 (Lt Blu), but it is a 3 pin connector.

1. What about the other two wires (ground and ?, which location)?
2. What wire goes to what pin on connector?

Thanks for any help... I have searched with no luck.

 

1 - green/white - ground - D22
2 - not used
3 - light blue - D7

thanks Relic1

anyone know what fits where when looking at connector from wire side?
