finally got ecu installed this weekend. I soldered the two most important inputs: the cam and crank trigger, then hit em with heatshrink. I stripped the crappy insulator off a ton a butt connectors and butt connected + heatshrinked the rest. Will post a pic of my I/O table. Actually fairly easy to figure out once I got the right wiring manual (which required me to try about 5 before getting one with the correct plugs and colors).
Protip for anyone else doing a similar thing: think about cable management the
whole time. seriously. beginning to end. Mine looked like this towards the end:

more for my own reference, problems ive had so far:
-tapped +14v instead of "on" +14v
-used wrong PClink software (G4 vs G4+)
-updated with wrong firmware
-main relay not energizing
-no spark when cranking, good spark while testing
-no RPM reading
-learned I had to use "ej25 Quad AVCS" trigger setup
-setting base timing - finding the mark on crank pulley
-have spark, fuel, offset, still no fire.
-IAT sensor: GM open element - drill tap intercooler
