93 check engine light

Its been so long since working on this car, how to read the codes? I'm surprised its not the number 1 topic in the faq's.

Connect black plugs under dash to read saved codes.

Connect only the green plugs to read current existing codes.

Connect green and black plugs and drive around to erase the codes. When the cel has a constant blinking (no more long and short blinks) that means there are no active codes.

Thanks. I sure had a heck of time finding and connecting and disconnecting the black plugs.
So which ones do you connect when checking the timing?
