Hi everyone,
I'm in the process on changing the engine of my OffRoad car. The new engine will be an EJ25 NA from a Subaru Forester 03.
At this point I'm working with the wiring harness and need to make sure I don't cut a cable that will be needed later. So the question is What cables should I keep? So far I have identified the following ones.

Cables to keep:
The Vehicle speed sensor.
The neutral position switch.
Rear Oxigen Sensor.
Front Oxigen Sensor.
Oil pressure switch.
Starter Motor.
THROTTLE POSITION SENSOR <= Not sure with this???
PRESSURE SENSOR
INTAKE AIR TEMPERATURE SENSOR
ENGINE COOLANT TEMPERATURE SENSOR AND THERMOMETER
KNOCK SENSOR
CRANKSHAFT POSITION SENSOR
CAMSHAFT POSITION SENSOR
IDLE AIR CONTROL SOLENOID VALVE
IGNITION COIL AND IGNITOR
AIR ASSIST INJECTOR SOLENOID VALVE
PURGE CONTROL SOLENOID VALVE <= Not sure with this???
CABLES TO FUEL INJECTORS
Sub fan motor
Radiator main fan motor
Generator

Which ones am I missing?

regards.

  Hi Fernando

  Keep relays and fuse box, and obd 2 connection.  Keep ECU unless using a aftermarket ECU, Stinger or other.

Thanks Steve,
Great PDF document Will be useful.
I'm planning to use original ECU and everything I could use from donor vehicle.

After removing tape from the harness, there are a looooot of cables to get rid off....

Nice exhaust. Is it protected in some way, that it is not affected in case of raining water getting in?

Car is usually in garage but if needed would place a 5 gal bucket over pipes if left for extended periods in the outdoors.

Talk to www.enginewiring.com; they rework Subaru factory wiring harnesses & can delete the unnecessary wires and sensors, they have a VSS & fuel tank sensor work-around, and they can re-loom your harness for a cleaner appearance.
