astra data/ diagnostic pins link - martin_n
I have a 1,4 astra petrol 1995 the engine management light comes on intermitently

i know i have to bridge pin a and b to get the fault codes , but i dont know which pins they are as they are not marked

the data link block has 2 columns of 5 connectors


thanks in anticipation
