Help needed- Autometer wideband to SCT analog cable

[Comin' in Hot]

I want to connect my Autometer wideband gauge up to my SCT XCal3, I have the analog cable, but I am not sure of the wiring. I've done a few Google searches with no clear answer.

Here are the two wiring diagrams:

Sometimes I'm blind, I didn't see this, this helps. Anyone know what the white wire on the SCT cable is for?
