There are two black wires coming out of the EFIS main connector. One of the two is quite short. The documentation only shows one black wire. What is the second one for?

I planned to use that as a ground to case for wire shields.

Hi Noah,
Tom has this right. The short black wire is tied to the serial line shields. This wire should be attached to the case connection screw that is located on the rear of the EFIS and labeled with a ground symbol. See the 'EFIS Main Cable' schematic for additional details.
Take care,

Ahh, I see it now, threw me locating it away from all the other wires on the diagram and not labeling it black. OK, cool - thanks.
