I've tried to jump my A & B connectors to get my car to flash it's diagnostic codes but that doesn't work on my 1994 Pontiac Firebird 3.4 V6. I've also read and have been told that the 1994 Firebird with the 12 pin ALDL isn't made to flash codes. I'm sure when GM made these cars they also made (or at least licensed) some way to retrieve the diagnostic codes. I REALLY want to find one of those original code readers but can't even start out looking until I know what they were called back then. I found a (new/in original box) Equus Model 3123 GM Code Reader and it says on the package that it only works on Firebirds up to 1993. Is it the GM Equus Code Reader 1.6..? Thanks

Thanks Goodguy. So you're saying I can use any scanner, even a brand new OBD2 unit , as long as I have a 12 pin-to-16 pin adapter cable?

that is right

I've been trying to self diagnose a rough running issue for like 3 months under the impression that I needed a OBD1 scanner to scan my OBD1 PCM and being told no OBD1 code reader would work on my car. This clears that up for me. I'm buying an adapter. Thanks.
