1985 K10 ALDL

[Emfinger]

My ALDL only has A, B, C, D and F
I can't find a ECM pinout that looks like it. Nor a wiring diagram for the carburetor-ed 1985 K10 "M" truck.
With ECM labeled 2015 102 77767282 77-6865 Claims to replace 1226865 .
Can anyone point me in a helpful direction?

Thank you for your time.
