Pins #15 & #31 on "Black" connector to PCM

These are the Battery Feed Wires for the PCM, Where do they get their power from?

Shoebox's wiring diagrams are for a 95, but they show the feed to those two pins coming from the red +12V box, through a fusible link, then to fuse #4 in the instrument panel, then to connector C210, then splits to the 2 PCM pins.
