Found this inside the wiring harness, wrapped up in black tape. I'ts been disconnected for some time. 12ga wire, green with no tracer

Naasty little splice from years ago. Could it have gone here? The original wire looks to be in the 10-12ga. vicinity, black, no tracer & is very brittle. This one is getting replaced when the time comes. It was connected to the power side of the starter solinoid.

Also found this wire when I pulled the loom off the wires going up to the voltage reg. Looks like it loops back down. Wondering what it was for. Black wire, no tracer, 10-12ga.

I havent had time to pull the looms/black tape & trace everything. Not to that point yet.
