A9l wiring question
For my truck, I use the A9l ecu. Currently I have a problem with my passenger side O2 sensor. The problem is the "ignition run circuit". I need to trace this wire but don't know where it goes. In the A9l diagram, it doesn't specify where it goes.
Can anyone tell me where this wire goes?

Correct about the harness. When I search on line for the A9l wiring diagram, I see the O2 sensor has a wire that goes to 'ignition in run'. I have a problem with that wire but I don't know where it connects to on the other end

I'm getting a lean condition on the passenger side, when the motor is running this wire should have +12v but mine has no voltage when running
