Question Can someone help identify what this black with white stripe wire, next to the computer, is?

While correctly wiring my 86 for mass-air, I came across this 12 gauge (or so) wire. It's black with a faded white stripe and what looks to be a connector, or maybe a fusible link, but nothing on the other end. Any ideas?

Not sure how different the 86 is from 88-90, but there is a BK/W wire, circuit 359 the goes to several things in that area.

It goes to the self test connector, and serves as signal return for various sensors. Should go to pin 46 on the PCM.

Again, it could be different for 86, but the manual I have is for a 90.
