Okay, here is what has been going on. First off, i really have no use for the A/F gauge. the only reason I am trying to solve this is to make sure i get the O2 working properely. my A/F gauge has been reading Ov since the swap (no lights at all unless i unplug the sensor wire and get the 1v solid green led). I went ahead and got a different O2 sensor from hams for a test to see if my other was bad. I still get nothing on the gauge when it is plugged in. Now I am going to the harness to the 16" extension section to see what I can find. What color of wires am i looking for in this extension section that go to the O2? I believe that they are pink, white and blue? do all of these have to be shielded? I was told that it wasn't that important on the O2. i will just make sure I have a good connection at least. So, i am just using this O2 gauge to test the O2 i guess. Any other input is great for future reference.
