OK I have been looking at things like the Auto Tap programming unit. It saids it needs an OBD II connector to work so I thought that ment it was only for 95+ F-Bodys. Turns out some 1995 Z28's (which is what I own) have OBD II connectors or that is what I heard. So I'm little confused here, do all OBD I computers have OBD I type connectors or do some of the later OBD I's come equipped with OBD II style connectors?

 

1995 V8 F-bodies are OBDI with an OBDII connector. Even though they have an OBDII connector, OBDII scan tools and programmers will not work.
