I need to know what wires on an obd2 s14 engine harness need power (12v) in order to have a functioning car.

The short:
The car (ka24det s14) is wired on an 8 switch relay panel. No body harness. Switches for ign, start, fuel, lights, fan, blah. The engine harness is mostly in tact, after some work.

After a bit of research, it seems that only the eccs relay pin 4 and ign switch pin 38 need 12v to have a running car. This proved correct, as the car does start and run, although like total shit.

Am I missing power to anything else?

After digging in a bit more and checking out my AEM ems wire view, looks like I need provide power to pins 56, 61, and 70. That might be why I couldn't get the ems to sync. Can anyone confirm?
