stand alone question
does buying a standalone ecu completely replace your wiring harness?
second of all, how much of a wiring harness has to actually be plugged in for the car to run? im still fighting with putting my harness in and i dont have a bac plug and im missing atleast one other plug, thanks

Generally, yes. A standalone would replace the emissions harness.
The stock ECU will run with only the following sensors:
AFM
CAS
It won't run well, but it will run. Minimally for a properly running stock ECU you need:
AFM
CAS
TPS
Intake Air Temp
Engine Coolant Temp
Boost / Pressure Sensor
Atmospheric Pressure Sensor
Knock Sensor
O2 Sensor
Everything else can be unplugged and the car will still run.
