Here goes
The ALDL slots are FEDCBA from left to right.
Slot:F goes to ECM connector A7-Brown with black stripe wire
E goes to ECM conector A8- orange wire
D goes to ECM connector A5-black with white stripe wire
C- not listed Maybe not used? I would have to take ALDL down to check
B-goes to ECM connector A9-white with black stripe wire
A-goes to an m symbol-Probably ground- I am no electric expert
Hope this helps- Brad
