Thanks for any input.

Can't be definitive, but . . . on this wiring diagram
http://www.wiringdiagrams21.com/wp-c...ng-diagram.gif , BLACK/YELLOW is a common connector to the battery negative terminal, or GROUND. Don't know if, prior to 1990, other ground connections were used for the CDI and for the starter relay; the wiring diagram linked shows YELLOW/BLACK as a shared battery negative connection, throughout the wiring scheme.
Before you swap out wiring harnesses, I'd suggest you take your ohm-meter and run a continuity check between the CDI and the starter relay connections and ground, with and without the BLACK/YELLOW wire connected to each terminal. If the terminals show continuity with ground without the wire, looks like
machts nichts to me, suggesting the '90-and-later connection might be for redundancy and insuring a low-resistance path to ground. Postulation and inference, only!
