I have read numerous threads that say i need to log wideband data through the AC pressure switch/ sensor. It is supposed to be a red/black wire? So which wire would that be for a 01 tahoe? I have A/c request signal, A/C low pressure switch, A/C high pressure recirculation switch, or recirculation door control.
None of these are red/ black which one do i log through? Can someone help?
I am using a MTX-l and will be using the factory o2 sensor location. thanks
