I have read in different postings where the computer in the 1995 LaSabre is an ECM, it is described as OBD 1.5., it isn't a true PCM. It has an OBD2 style terminal block but it is my understanding that it isn't wired like a true OBD2 terminal block would be wired. Is there a way to read it without a scan tool?
