WTH is the ALDL? Is this another term for the ECM (engine Control moduel?
I am not sure exactly what ALDL stands for, but it is the plug to connect a computer to so that you can read the ecm. In the Fiero it is located right behind the cigarette lighter. The ECM is right beside the drivers right hand shoulder, behind the "glove box" in the center console.
The ALDL connector, connects a computer to the ECM. You can also use the ALDL to flash the Service Engine light so that you can read the codes that the ECM has stored. This is done by jumpering two pins. You can find out more on reading codes here on the forum. On the main page Cliff has a link to it.
