I am re-wrapping my SC400 wiring harness and I want to eliminate as much wires as possible to tidy up he harness. Emissions, ABS and TRAC has been deleted so I do not need all those extra wires in the harness. My question is:

What are the minimum sensors needed for the ECU to not trigger limp-mode?

What I am sure it needs:
- Knock sensors
- Injectors
- Crank Sensor
- Cam sensors
- Igniters
- Hydro Fan pressure sensor (disconnecting this sensor will cause the oil light to come on and stall the engine - important to notice if doing E-fan conversion)
- Hydro tensioner sensor (same as above, disconnecting this sensor will cause the oi light to come on and cause the engine to stall)
- MAF
- All trans sensors
- O2 sensors

What I am not sure about:

- Does the ECU need all the temp sensors? If not, which one does it need?
*There are 3 temp sensors on the front coolant bridge and one in the radiator.

- Does the ECU need the oil pressure sensor located by the oil filter?

- Does the ECU need the oil level sensor located on the left-side of the oil pan?

- Does the ECU need the power steering pressure sensor connected to the PS rack?

- Does the ECU need the air temp sensor located under the top-intake plenum?

- Does the ECU need both TPS sensors? (TRAC vs. normal)

Keep in mind, my question is which sensors are REQUIRED for the ECU not to run in limp mode and not what missing sensors will cause a check engine light. I know well what can casue a check engine light and that is not my concern - since I am rewrapping the harness I want to eliminate as much wires as possible to clean this out.

Any help is appreciated.
