Q: service engine light came on and stays on, I need to diagnose problem for smog on 1995 Oldsmobile Cutlass Ciera

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
Beginning in 1994, GM began the migration to the ultimate goal of all vehicles being OBD-II compliant, and my Oldsmobile is in the 20% or so that were sent over prior to 1996. Actually, it is a hydrid, mostly OBD_II compliant, yet packed in an OBD-I form. I have observed this by the changes in the ALDL connector. only 12 pins and cant use the usual jumper from A to B. so can modern scaners (OBD-II help me?

So if I take my car with the 12 pin DLC to say Pep-Boys, will they have the adapter to go from 16 pin to 12 pin DLC? Or should I go to a more Professional service center?
