More 86/87 wiring diagram questions for the experts

Ok that makes sense and that's why I don't have it when I bought this harness. I guess I will have to make one up.
Can you tell me what the connector is for from my photo in post 15? Thank you

what is the dash harness from
if i had to guess its a regular regal and that plug is for the over the glovebox lamp module

That plug in my post 15 is part of the engine harness which I'm told is from a GN 86/87.

i see your pic (post #18) with the large grommet for the firewall and the connectors for c437 and the ecm , thats alll the wires that go inside the car
, where the hell does that flat connector (A-F) come from on the engine harness

its for the HVAC control , has nothing to do with getting it to run
it gets into the car through grommet at the bottom right of the AC box

techinically its not part of engine harness but does plug into it under the hood for power and blower control
