COMPLETE ALDL PORT PINOUT

[turboponcho89]

Spent some time doing searches. Not a single website explains each pin and its function. I think I got it all but feel free to add your input.


What is found on most any search I performed...



My notes as information was gathered.



Turbo T ALDL port



TTA port



Syclone



Post a pic of your car's if it differs in any way.

Didn't find it. Must not be looking in the right place.
Please keep in mind OBD I was used thru 1995 so not all pins apply to every GM vehicle of the era.
