O2 elimination

[Lithium]

Can some one tell me why my GTO ECU is missing the pin for one of my o2 sensors at the ECU. My ECU has no pin in pin 55 which is heated o2 sensor wire per stealth 316. anyone have any idea why that would be?

GTO's only had one o2.

GTO's only had one o2.

I was hoping you would say that. Would that possible be pin 56???

That I cannot answer with 100% positiveness. We'll let someone who knows for sure help out here.

Any one with a GTO want to help me out? I need to know the o2 position in the exhaust and its heated signal wire at the ecu.

It's probably the same as the non-turbos with one O2. This would make pin 56 the signal wire and the single sensor would be positioned at the rear of the downpipe right before the cat.
