I'm new to the Honda tuning scene as I bought my mid-life crisis car last fall so I'm probably will get blasted for my questions about the wiring but here goes:

I see all the insulation grounds of the grey wires coming out of the firewall tied to a Logic Ground of the B Pin 2 connector. Is this done from the factory? I don't see the insulation grounds being used on the engine side of any connector so I wondered why this was done. If it is used for signal I would think you would pick up noise this way unless it was tied directly to battery ground somewhere.

I see a white wire in a solid grey cable not connected (assumed it to be a D Primary Heated O2 sensor wire). The D Pin 14 connector wire (green/yellow) was also floating but I do not know if it was tied to ground, 12V or other. I assume this was what the white wire was tied to originally from the factory.

I have been throwing an intermittent code 17 VSS error and had replaced the VSS but still have the intermittent code. Wondered if some of the floating wires might have something to do with a bad signal.

I know the car was tuned with Uberdata but I have to look at the programming to see what sensors were disabled or reprogrammed etc. The engine has been modified with performance items plus a turbo but I lack detailed information of the complete (real) mods it has.

Thank you in advance for any help anybody can provide.
