PRB Conversion PRA Car, a different way... possible?

[Sandaman]

- Remove the pink wire from connector E4 (signal ground 3) and connect to A16 (Primary Heated Oxygen sensor - ). This is best done with an AMP pin removal tool. A16 is unused on the UK Civic Type R harness.

- Unplug the rear oxygen sensor and disable OBDII in K-Manager.

- Connect A22 (use a T-Tap) which is unused on the UK Civic Type R harness to A2. This provides a switched 12V to the ECU to tell it that the oxygen sensor heater is receiving 12V and working.

Quite simple and straightforward question:

Cant I just wire the pink wire of the primary O2 directly to A16, that way I can leave the secondary O2 sensor alone(and keep it connected) and don't have to disable OBDII?

[Mr Aryan]

would love to know that too

Since I get no answers, let me put it this way:

Is E4 on the PRB ecu used for the secondary O2 like on the PRA ecu?

I've developed a scheme for this propose



it's not tested, but I think it's right on schemes, can you finish that develop trying that
