4-I did not do anything from connector to ECU. All does look good however when I unplug the connector. No corrosion or bent pins.

Got any ideas other than continuity check from plug at ECU to O2 plug?
Gotcha. Thank you for clearly answering those.

I would still suggest checking continuity from the DME connector to x6200 just to make sure the issue isn't there.

When you get a chance to check the continuity from the O2 plug to x6200, you'll most likely need a spare wire extension to check the loop. The purpose of this is to isolate where the issue is as it might be on pin 6 or even further up the chain.
