Hello,
I replaced the wire harness in my 97 k1500 5.7 with a new replacement from GM about a year ago. The replacement wire harness did not come with wires for the 02 sensors or egr, egr I'm not worried about but I would like my front 02's. I cannot find clear data or diagrams as to what wires for the 02's go to what pin for the pcm. I found some pin out charts but cant make sense of what o2 is what and where the heater circuit wires go to. Any assistance would be appreciated.
