Here's how to retrieve the codes. https://www.fiero.nl/cgi-bin/main.cgi?ECMCodes As for the bulbs, you will have to remove the back of the instrument cluster, and I believe you can reach some of them that way, but for some of the lower ones you will have to remove the cluster. There are instructions in a Haynes manual, and probably a thread here on the forum about it also.
I've seen the article here on where the connector should be, but my lighter is between the seats and all I have is a Chilton's Manual and it isn'r much good. Thanks for the reply
Using the appropriate Torx bit, remove the black trim plate where the lighter is located. Peek back inside and on the passenger side of the opening, you should see the ALDL connector. The two terminals that you jumper are the two on the lower row, passenger end of the ALDL. Illustrations in the manuals show the ALDL as it's mounted underneath the dash in other vehicles. In the Fiero application, for some reason they mounted it upside down, so the 2 terminals are just the opposite.
Be sure you have the ignition off when you insert the jumper and when you remove the jumper to prevent possible damage to the ECM. Record any codes stored, then go back to the battery area and unplug the round barrel type connector for about a minute to clear the trouble codes. It's easier than disconnecting the battery cable and it doesn't delete your radio pre-sets.
Welcome to Fiero fun and frustration. I was up in Yorktown a few years ago and bought an 86GT from the owner of the Duke of York Hotel on Water Street. Nice area up there.

It's right behind that plate that surrounds the lighter, just like Fierofool said. Just remove 2 screws with the torx bit heads. The link I provided didn't say where it was located. I was assuming that was a given.

A ya in this case it is in even the Chilton manual, where the OB1 plug is, as others have said it is right behind the lighter plate, remove the 2 torx screws holding that on, remove the plate and you can't miss it. just because in most other cars it was visible doesn't mean it is in all of them.

Thank you to all that replied to my request for help in finding the ECM test connector, if it wasn't for this web site and you, I would never have found it. 1Fred
LOL he's helping stop telling him to stop helping, That a future Fiero mechanic that guy has right there, or maybe he could be his camera man next time he makes a you tube video.
