Vette(s): 77 coupe, yellow, auto, L series, A/C, T top, Grey leather interior. It is about 75% & matching #'s. The miles are 117K & intend on restoring bit by bit to enjoy Cruises & rallies in Florida , & maybe some shows ?

Can anyone tell me which pins are A & B on my ECM connector under the dash. I have an early 86 with a 12 pin connector. I do not want to jump the wrong terminals in order to read the flash codes & hurt the electronics. So a picture or explanation will help me out. Thanks in advance guys.
