GM ECM into '72 datsun wiring diagram Low Rez

This is the wiring diagram I created for my (original) swap of a GM '7747 ECM into my '72 Z. I basically copied an original Z diagram, modified it, and then drew in the necessary parts of the ECM diagram. Note that all switched (+) power for the system comes from a central distribution terminal dedicated to the ECM, except for hot leads (generally heavy loads) to relays, which are separately fused (though that's not really shown - sorry). This distribution is shown in the same way that GM did it, with a note "switched" at the appropriate spots. I was mostly interested in debugging the simplified ECM wiring.

Currently I'm running a '7730 ecm, which uses different pins on the ECM, though they generally have the same names (and functions). I didn't have to change any sensors out for that modification.
