just wanted to give an update:

culprit found..

when i had no power at pin 26 on the x60004 DME plug, that essentially powers the DME via ignition...

pin 26 from that plug goes to the E36 X20 round plug, to pin 22, which is protected by fuse 26 on the E36 fuse box... sure enough that damn 10a fuse was blown.

I didnt see it when checking fuses cause a 10a BMW fuse is so thin and sits on top that i missed seeing, only until i pulled the fuse and used my glasses..

changed the fuse and starts up immediately.

Thank you to all who helped and explained wiring, again its something im really weak on but this process helped understand to read schematics and trace wires.
