Bringing this back.
So today I ripped the harness out of the car. I'm moving my battery to the cabin and want to clean up the bay some more. I decided to check the wbo2 stuff again after the harness was removed. I have no continuity between the orange wire and the shielding wire. However, the road speed wire and shield does.
Everything checks out otherwise. I'm curios as to what will happen when I re-install the harness.
My problems were that my 02 input wouldn't read the AEM voltage.
My fan DPO didn't work.
Any thoughts?
Should I be connecting it like this?

I've done everything stated in this thread.. im out of ideas. got it all plugged in yesterday, started it up. AV1 just sits at 2.5 volts.. all of the grounds checked out, everything. im starting to think it could be the ECU.. im going to try and back probe the Av1 wire with the AEM wire, and see if i can get a reading.
Other that that, this car runs awesome. I cleaned up some grounds and it seems to run a lot smoother.

Shielding to ground had continuity, Ground to Av1 showed nothing.. That means no short right?
Hopefully going to be able to get back in it on Tuesday. If anyone as any ideas please share them.

There isn't another ground that needs to be hooked up anywhere is there? Just a thought.. I wouldn't think so if everything else in ecu is working... But just an idea

ok i know its probably not the case but make sure that where the grounds in the ecu all connect that they are a solid connection... on my e6k all the the grounds connect at one pin to the ecu if i remember correctly...
