Default Obtain code on 1990 ALDL

What pins need to be grounded on the ALDL in order to make the codes flash?

Is the Killebrew ALDL diag manual just an echo of the Chilton explanation of the codes?

A and B or A and G

it depends on which you want to see, and, how quickly you can count blinks!

A and G is the best, and for detail on how it works, check this thread (versus me typing for 2 hours ):
