Question What is this black box in rear trunk near ECU?

What is the black box to the right of ECU on this 1999 986 manual? This is the kind of wiring you do NOT want to find when troubleshooting a no-start situation. The mystery box has 2 wires coming out of it: red and black and they connect to a yellow and black wire from the harness.

It looks maybe like a remote starter as I "think" the yellow and black are ignition and starter.

Any guesses and any idea where the yellow and black wire should go instead of this box ? Thanks in advance.
